The Mistake of Not Setting Aside a Contingency Fund

If you’ve ever watched a build or renovation go sideways, you can usually trace the stress back to one decision made at the very beginning: not setting aside a contingency fund. The plan looked airtight, the spreadsheet felt comforting, and then reality walked onto the jobsite with a sledgehammer—hidden rot, a permitting delay, a blown lead time on windows, a code change, a surprise utility line under the driveway. I’ve managed enough projects to know that contingency isn’t a “nice-to-have.” It’s oxygen. Without it, every hiccup turns into a crisis, relationships strain, and the project quality suffers. With it, the job breathes.

What a Contingency Fund Actually Is (and Isn’t)

A contingency fund is money reserved to cover risks you can’t fully define at the start—unknown site conditions, price volatility, code changes, design clarifications, and owner-driven tweaks you’ll swear you won’t make but probably will.

What it’s not:

  • It’s not a slush fund for random upgrades you decide to add “since we’re already opening the walls.”
  • It’s not padding for a contractor to boost profits.
  • It’s not a substitute for good planning, due diligence, or proper estimating.

Think of contingency as your project’s shock absorbers. The goal is to finish with some of it unused, not to avoid setting it aside so the budget looks prettier on paper.

How Much Contingency Do You Need?

Short answer: more than you think, tailored to project type and risk.

Typical ranges I recommend (based on residential and small development work):

  • Ground-up custom home: 8–12% of hard construction costs. I personally prefer 10–12% unless it’s a truly simple build on a clean lot with full geotech and survey.
  • Major renovations/additions: 15–20% of hard costs. Older homes with unknown wiring, plumbing, or structural quirks push toward 20%.
  • Light cosmetic remodels (no moving walls, no major MEP changes): 10–12%.
  • Land development or complex hillside/urban infill: 12–20% plus 2–3 months of carry reserve for delays.
  • Flips/investor rehabs: at least 10–15% on scope you control, and 5–10% on market/carry risks.

Lenders often require a contingency:

  • Construction loans commonly require 5–10%.
  • FHA 203(k) renovation loans typically require 10% and can go up to 20% if utilities are off or risk is higher.
  • Fannie Mae HomeStyle renovation loans often include around 10% contingency depending on the consultant and scope.

If you’re under 10% on any project with real unknowns, you’re betting the house against statistics. On countless projects, I’ve seen that “we’ll be fine” optimism cost far more than a properly sized reserve.

Where Cost Overruns Actually Come From

It’s not just “surprises behind the walls.” Overruns compound from small events and choices:

  • Hidden conditions: Painted-over knob-and-tube wiring, asbestos, termite damage, failing drain tiles, rock during excavation, undersized joists, rotted sill plates.
  • Scope creep: Adding can lights, upgrading tile, switching to inset cabinets, choosing a higher-end roofing system after seeing samples.
  • Design clarifications: Details the drawings didn’t fully resolve—fire blocking requirements, insulation around tricky transitions, stair headroom adjustments, beam sizes after final engineer review.
  • Price volatility: A quote that holds 15 days on specialty windows suddenly expires; steel prices rise; mechanical equipment lead times force product changes.
  • Permitting/code shifts: Plan checker requires additional shear panels; sprinklers get triggered by your design area; energy compliance pushes you to a different HVAC layout.
  • Weather and sequencing: A week of rain, a cold snap delaying exterior finishes, or a supplier backlog cascading through trades.
  • Owner-caused delays: Late selections, long-lead materials chosen after rough-in, design edits after framing.

Each one is manageable with a reserve. Without one, they chain react into redesigns, rework, schedule gaps, and compromises you’ll regret.

A Tale of Two Budgets: What Happens When You Skip Contingency

Let’s walk through a real-style scenario. Names changed, pain intact.

Scenario A: Custom Home Without Contingency

  • Budget: $600,000 hard costs + $100,000 soft costs. No contingency.
  • During excavation: hit ledge rock. Extra blasting and haul-off: +$24,000.
  • Structural revisions: engineer upsizes two beams based on actual spans: +$8,500.
  • Window lead time: chosen brand delays delivery 5 weeks; switch to comparable brand: +$6,800 due to frame upgrade.
  • Well depth: expected 220 ft; actual 380 ft plus stronger pump: +$12,500.
  • Energy code update mid-permit: additional exterior foam and detailing: +$14,000.
  • Owner changes: add four skylights and two exterior outlets: +$5,100.

Total: +$70,900 above budget. Cash scramble starts. They trim landscaping, downgrade countertops, cut the covered porch they really wanted, and stretch the schedule by six weeks while waiting for funds.

Scenario B: Same Home With a 10% Contingency

  • Budget: same base costs, plus $60,000 contingency.
  • Same surprises total +$70,900. The builder and owner meet weekly to prioritize.
  • They cover the first $60,000 from contingency and choose to defer some upgraded lighting and site extras to save $11,000.
  • Result: high-quality structure, no debt scramble, schedule impact reduced to 2 weeks, relationship intact.

The difference isn’t that the second project had fewer surprises. It had faster, calmer decision-making and far less downstream damage.

The Psychology Behind Underfunding Contingency

  • Optimism bias: We think our project will go “as planned,” even though almost no project ever does.
  • Anchoring: Initial numbers harden in your mind. Any increase feels like failure, so you resist adding contingency to keep the spreadsheet “clean.”
  • Scope blindness: You underestimate the complexity and interdependency of trades, materials, and scheduling.
  • Decision fatigue: Without a reserve, you frame every choice as binary—spend or fail. With a reserve, you can make nuanced trade-offs.

A contingency fund isn’t permission to spend. It’s permission to think clearly under stress.

How to Size Your Contingency the Smart Way

Instead of picking one percentage and hoping for the best, break contingency into buckets tied to actual risks. Here’s the process I use with clients.

Step 1: Identify Known Unknowns by Category

  • Site: soils, rock, water table, utilities depth/condition, drainage.
  • Structure: framing corrections, beam sizing, termite/dry rot repair.
  • MEP (Mechanical/Electrical/Plumbing): panel upgrades, venting routes, plumbing reroutes due to structural conflicts.
  • Envelope: flashing details, insulation upgrades to meet energy scores.
  • Interior: framing for specialty finishes, custom shower prep, tile layout complexities.
  • Admin/Soft: plan check comments, additional surveys, architectural revisions.
  • Schedule: weather days, long-lead swaps, inspections backlog.

Step 2: Assign Ranges per Category

  • Site: 2–5% for clean infill; 5–10% for rural/hillside or unknown soils.
  • Structure: 1–3% new build; 5–8% old homes.
  • MEP: 1–3% new build; 5–10% renovations.
  • Envelope/interior: 1–3%.
  • Soft/admin: 0.5–2%.
  • Schedule/carry reserve: at least one month of interest, temp housing, or rent overlap; two months for big renos.

Add them up and reconcile to an overall target (10–20% depending on project type). If your bottom-up sum is 9% on a 1950s house with a basement, you’re kidding yourself.

Step 3: Separate Owner Changes from True Unknowns

Create a small Owner Upgrade Reserve (2–4%) separate from the contingency. This keeps you from raiding the unknowns bucket when you fall for nicer fixtures. It also keeps you honest. If you upgrade past that reserve, you’re making a conscious choice, not stealing from the risk fund.

Step 4: Add Escalation Buffer if Your Timeline Is Long

On a 12–18 month build, carry a 2–4% price escalation buffer unless materials are locked. Negotiate price locks or stock materials early where prudent.

Step 5: Translate Percentages into Real Numbers

If hard costs total $550,000:

  • Base contingency (new custom build, modest risk): 10% = $55,000
  • Owner upgrade reserve: 3% = $16,500
  • Carry reserve for delays (two months P&I and temp living): $8,000–$15,000, depending on your financing and housing.
  • Total cash reserve plan: roughly $80,000–$90,000.

People who balk at this number rarely balk when change orders trickle in for a cumulative $75,000. The difference is you’re choosing your pain upfront or in the middle of the project.

Where to Park the Contingency and Who Controls It

The answer depends on your contract structure.

  • Lump Sum (Fixed Price): The contractor prices the scope; you hold an Owner Contingency separate from the contract sum. Change orders against that fund are approved by you. If the contractor includes a contractor contingency, ask what it covers (means/methods risk) and how unused funds are handled.
  • Cost-Plus with GMP (Guaranteed Maximum Price): There is often a contractor contingency inside the GMP for coordination and minor scope gaps. You still hold an Owner Contingency for unknown conditions and owner changes. Negotiate transparency on how contractor contingency is used and whether savings return to you.
  • Cost-Plus (No GMP): High trust, high transparency. You absolutely need an Owner Contingency because there’s no ceiling. Use tight change order protocols.

Always:

  • Keep the owner contingency in a dedicated account, not mixed with your general checking.
  • Track spending with a live change order log. Review at least weekly.
  • Agree on approval thresholds. For example, the builder can authorize up to $1,500 for urgent safety/code issues; anything else requires written approval.
  • Document with photos and memos. Paper wins every argument.

What Good Preconstruction Really Saves You

Contingency isn’t a substitute for due diligence. You’re lowering the amplitude of surprises, not inviting them. Here are preconstruction steps that shave risk—and I mean materially:

  • Geotechnical report and percolation test: $2,500–$5,000. Can save $10,000–$50,000 by properly sizing foundations, drainage, and septic.
  • Site survey with topography and utilities locate: $1,800–$4,500. Avoids setbacks, encroachments, and costly grading mistakes.
  • Camera inspection of sewer lateral: $250–$600. Failure mid-build can be a $6,000–$20,000 surprise.
  • Exploratory demo for renovations: $1,500–$3,000. Open a few surgical holes to inspect structure, wiring, plumbing. Catch knob-and-tube or concealed rot now.
  • Hazardous materials testing (asbestos/lead): $300–$1,200 for samples. Abatement is manageable when planned; chaotic when it shows up mid-demo.
  • Detailed takeoffs and scope alignment session: half a day with your GC and lead subs. Clarify allowances and unit prices for unknowns (rock excavation, extra joist replacements, additional insulation areas).

The best savings I’ve seen came from $4,200 spent on due diligence that prevented a $37,000 foundation redesign and schedule slip.

A Quick Primer on Allowances, Alternates, and Contingency

These three get tangled and cause fights. Here’s how to keep them straight:

  • Allowances: Placeholder amounts for items not fully selected at contract time (e.g., tile at $10/sf material, appliances at $12,000). If your selections exceed the allowance, you pay the difference. Allowances are not contingency.
  • Alternates: Optional scope items priced separately (e.g., standing seam roof instead of architectural shingles at +$18,000). Use alternates to keep dream items visible without committing funds until you see how contingency plays out.
  • Contingency: Reserved funds for unknowns or necessary changes, not preplanned upgrades.

Pro tip: If you know you’ll want the nicer tile, increase the allowance upfront. Don’t pretend the baseline is fine and plan quietly to raid contingency later. That’s how budgets die.

The Real Cost of Not Having a Contingency

You lose more than money when the project gets tight.

  • Quality erosion: You start cutting waterproofing, flashing, or inspection steps—exactly the wrong corners.
  • Schedule slide: Every decision requires a financial meeting; work stops while you figure out funding.
  • Adversarial relationships: Contractor and owner start protecting their own interests. Collaboration turns into “prove it.”
  • Financing issues: If a lender won’t fund the overage, you’re forced into high-interest credit or scope reductions that devalue the result.
  • Emotional toll: I’ve watched owners who loved their project become exhausted by day 90 of “Can we afford this?” The joy evaporates.

On the flip side, funded projects move faster and make better decisions. You can say yes to the right solutions at the right time.

Case Study: A 1954 Ranch Renovation

Scope: 1,600 sf ranch, new kitchen, two baths, new roof, partial rewiring, open up between kitchen and living room, new HVAC. Budget target: $210,000. The owners initially wanted only 7% contingency; we settled on 17% after a walkthrough.

What happened:

  • Opened walls: found cloth-sheathed wiring spliced in wall cavities. Full rewire required by inspector. +$12,800.
  • Floor sag at hallway: two compromised joists due to past plumbing leak, rot in subfloor. +$5,600 for sister joists and subfloor replacement.
  • Asbestos in old floor mastic: abatement +$3,900.
  • Venting conflict: hood vent path blocked by beam; needed reroute and low-profile ducting. +$1,700.
  • Owner changes: upgraded to quartzite counters, +$3,400 over allowance.

Total overages: $27,400. Contingency was $35,700. We finished with $8,300 left, which the owners used for a small patio and better lighting. Without that reserve, they would have cut back on the electrical upgrade—the worst possible decision for safety and resale.

How to Release and Track Contingency Without Losing Control

  • Set a simple rule: Any use of contingency must tie to one of these categories—unforeseen condition, code/compliance change, documented design ambiguity, or owner-requested change. If it doesn’t fit, it doesn’t spend.
  • Keep a single source of truth: a change order log with:
  • Description
  • Category (Unforeseen/Code/Design/Owner)
  • Cost impact
  • Schedule impact
  • Decision date and who approved
  • Before/After contingency balance
  • Review weekly: Five minutes is enough when you stay on top of it. Waiting a month means surprises and friction.
  • Pre-approve unit pricing: Rock excavation per yard; additional joist replacement per lineal foot; framing backout per opening. When conditions hit, you can authorize quickly at known rates.

Financing and Contingency: How Lenders Treat It

  • Construction loans: Many lenders include a contingency line in the draw schedule—often 5–10%. If you don’t spend it, great; it reduces your final loan. If you do spend it, it’s funded like any other draw with invoices and inspections.
  • Renovation loans (FHA 203(k), Fannie Mae HomeStyle): The contingency is usually required and retained until needed. For 203(k), it’s commonly 10%, and may be 15–20% if utilities are off or risk is higher. Understand that you can’t redeploy those funds for pure upgrades until certain thresholds are met.
  • Appraisals: Appraisers look at total project cost to establish future value and Loan-to-Cost Ratios. If your contingency isn’t recognized and you blow through the budget, you risk out-of-pocket overruns that don’t increase appraised value.
  • Carry costs: Build a separate reserve for interest, rent overlap, temporary housing, storage, and moving. A two-month buffer is sensible on most renovations. On longer projects, three months has saved more sanity than I can measure.

Contractor Negotiation: How to Keep the Peace and the Budget

  • Ask for a contingency narrative in the proposal: If the GC carries a contractor contingency, what does it cover? Coordination errors? Minor scope gaps? What happens to unspent funds?
  • Set markup caps on change orders: For example, 10–15% overhead and 5% profit on COs. Transparency reduces suspicion and the temptation to procrastinate decisions.
  • Agree on weather days and schedule float: Put in writing how weather delays are counted and documented. For many regions, expect 5–10 weather days in a typical season; more in rainy/snowy climates.
  • Align on allowances: Use realistic allowances that match your taste. If you know your bath tile will be $18–25/sf, don’t let an $8/sf placeholder into the contract.

Reducing Risk Without Killing the Budget

You can protect yourself without throwing money at everything:

  • Lock critical lead-time items early: Windows, exterior doors, specialty HVAC equipment. A re-sequencing due to window delays can burn thousands in lost efficiency.
  • Design for flexibility: Choose products with multiple comparable brands. If one delays, you have a backup that doesn’t derail the aesthetic or budget.
  • Build alternates into the bid: Have priced options ready. If contingency stays healthy, you can accept the upgrade. If not, you haven’t designed yourself into a corner.
  • Use mock-ups and samples: A one-hour tile layout mock-up can save days of rework. Clarify grout lines, edge trims, and transitions before the tile is fully set.

Common Mistakes I See—and How to Avoid Them

  1. Underfunding contingency to “win” the budget meeting – Fix: Set the reserve based on risk, not wishful thinking. If you can’t afford a proper reserve, reduce scope.
  1. Spending contingency on upgrades in month one – Fix: Lock a rule—no elective upgrades from contingency until after rough-ins and first inspections, when the biggest unknowns are out.
  1. Mixing allowances and contingency – Fix: Track them separately. If you exceed an allowance, adjust the allowance or pay cash—don’t hide it in contingency.
  1. Not documenting decisions – Fix: Every change gets a signed change order, with a cost and schedule impact. It’s not bureaucracy; it’s how you avoid resentments and “I thought we agreed” moments.
  1. Not running quick root-cause reviews – Fix: After a painful change order, ask “What could we do earlier next time to catch this?” It’s amazing how many surprises were actually knowable with one phone call or a flashlight.
  1. Raiding contingency for decorator items while cutting performance items – Fix: Never downgrade waterproofing, flashing, structure, or HVAC quality to fund shiny things. Beauty fades fast when water gets in.

What If Your Contingency Is Running Low?

Options that won’t wreck your project:

  • Re-sequence and pause finish upgrades: Keep the shell, structure, and MEP quality intact; push some high-end finishes to a later phase.
  • Value-engineer selectively: Swap materials where performance is equivalent—e.g., engineered siding with proper detailing instead of an exotic species.
  • Tap alternates you priced earlier: If a nicer roof or patio was an alternate, formally reject it and restore that money to the core.
  • Seek modest financing top-up: If you’re within lender tolerance, a small line of credit can be cheaper than long-term regret on major compromises.
  • Seller credits or scope reduction on purchases: For investors mid-flip, negotiate credits around appraisal or listing price; don’t pour good money after bad on over-improvements for the neighborhood.

Do not:

  • Cut waterproofing, flashing, or drainage details.
  • Accept unvented or improperly sized mechanical systems to save a few thousand.
  • Skip inspections or testing.
  • Eliminate contingency visibility from your tracking—hiding the problem always makes it worse.

Schedules and Contingency: Time Is Money

A schedule contingency (time buffer) is just as crucial as a cost contingency. A two-week buffer can prevent a 6–8 week blowout once delays stack. Strategies:

  • Insert float into critical path items: 3–5 days in key sequences like window delivery-to-install, inspections, and utility tie-ins.
  • Build weather contingency aligned with your climate:
  • Northern winters: expect slowdowns for exterior work; plan interior sequencing to compensate.
  • Humid climates: allow extra drying time for mud, paint, and flooring acclimation.
  • Coastal zones: corrosion-resistant fasteners and stricter inspections—add calendar time for coordination.

Every day of delay usually costs in carry and inefficiency. A little schedule padding is cheap insurance.

Investors and Developers: Project Pro Formas Need Real Reserves

For small developments and flips:

  • Construction contingency: 8–12% ground-up; 10–15% renovation.
  • Soft cost contingency: 2–4% for design, permits, legal.
  • Carry contingency: 2–3 months of debt service and operating reserve.
  • Exit price sensitivity: Underwrite sales at a conservative comp and increase days-on-market buffer by 15–30% in cooling markets.

Stress-test:

  • Add 5% to construction costs and 30 days to schedule. Does your IRR hold above your threshold? If not, sharpen design or walk.
  • Include a permitting-delay scenario. I’ve had municipalities require surprise traffic studies or utility coordination that added 4–8 weeks.

Experienced operators don’t just carry the contingency—they actually honor it when tempted by scope creep.

Insurance and Contract Clauses That Play Nicely With Contingency

  • Builder’s Risk Insurance: Covers the structure during construction against things like fire, theft, and some weather events. Not a contingency replacement but part of risk management.
  • Unit pricing for unknowns: Pre-agree on rock excavation per cubic yard or hazardous materials abatement per unit. Speeds decisions and avoids price gouging during panic.
  • Force majeure and weather-defined terms: Be explicit about what qualifies and how it’s documented.
  • Allowance reconciliation schedule: Monthly reconciliation keeps allowance overruns from hiding until it’s too late.

Real Numbers: Sample Budget with Contingency Flow

Project: 2,400 sf custom home on a lightly sloped lot.

  • Hard costs baseline: $640,000
  • Sitework: $75,000
  • Foundation: $58,000
  • Framing/structure: $110,000
  • Windows/doors: $48,000
  • Roofing/siding: $62,000
  • Mechanical: $68,000
  • Electrical: $44,000
  • Plumbing: $46,000
  • Insulation/drywall: $36,000
  • Finish carpentry: $34,000
  • Flooring/tile: $27,000
  • Paint: $17,000
  • Misc./cleanup: $15,000
  • Soft costs: $82,000 (architect, engineering, permits, surveys)
  • Contingency: 10% hard costs = $64,000
  • Owner upgrade reserve: 3% = $19,200
  • Carry reserve (two months P&I and rent overlap): $12,000

During the job:

  • Unforeseen: extra drainage and sub-grade waterproofing +$11,500
  • Design clarification: upgrade LVL size +$3,200
  • Price volatility: alternative HVAC units due to lead time +$5,800
  • Owner changes: laundry room millwork and mudroom tile upgrade +$6,900
  • Waste line reroute after concrete sawcut +$4,600

Total unplanned: $32,000 (contingency draw: $26,100; owner upgrades: $5,900)

Remaining contingency mid-project: $37,900. With that cushion, the team green-lights the originally priced alternate for covered rear deck (+$18,500). Project still retains ~$19,400 in contingency heading into finishes, where small add-ons inevitably appear. They end within $8,000 of the initial contingency—money well-spent versus scrambling.

How Contingency Affects Resale Value and Livability

Spending contingency on the right things pays you back:

  • Structural integrity: Appraisers and inspectors catch shortcuts. Solid framing, proper beams, and code-compliant work translate into higher valuations and fewer buyer objections.
  • Moisture management: Correct drainage, flashing, and waterproofing prevent the single most expensive category of residential construction failures.
  • Electrical capacity and layout: A modern service panel and thoughtful circuits improve livability and reduce insurance headaches.
  • Mechanical performance: Properly sized and commissioned HVAC keeps energy bills down and comfort up, which shows in buyer feedback and energy scores.

I’ve seen homes that cut waterproofing to “save” $3,000 end up with $30,000–$60,000 in remediation and a stigma that kills resale. Contingency gives you the stamina to do it right.

Selections and Deadlines: Your Secret Weapon Against Budget Bleed

Selections made on time are a hidden contingency saver. The later you decide, the fewer options—and the more expensive the fixes.

  • Establish a selections calendar by phase:
  • Pre-framing: windows/doors, roofing, siding, exterior colors
  • Rough-in: plumbing fixtures, tubs/showers, HVAC equipment, electrical layout and fixture rough
  • Drywall: tile patterns, trims, cabinet layouts
  • Finishes: hardware, paint, flooring, appliances
  • Build submittal/approval lead times into the schedule. If your chosen faucet takes 9 weeks, you need that order in long before rough-in to check rough heights and valve types.
  • Aim for 85–90% selections before demo or excavation on renos. On new builds, have the big-ticket items locked before framing. This habit alone can reduce change orders by 20–30% in my experience.

Regional Risk Adjustments Worth Considering

  • Coastal/marine environments: Stainless or hot-dipped galvanized fasteners; higher-grade flashing; more inspection scrutiny on connections. Budget for that and carry a bit more contingency for envelope detailing.
  • Cold climates: Longer drying times, potential temp heat, and season-sensitive exterior work. Add calendar float and fuel costs.
  • Expansive clays and high water tables: Geotech is not optional. Contingency for foundation and drainage adjustments should be toward the high end of the range.
  • Wildfire/High-wind zones: Upgraded roofing, vent screens, tempered glass, hold-downs, and inspection rigor. Price and schedule contingencies go up accordingly.

Taxes and Accounting: Track It the Right Way

  • Keep detailed change orders and invoices tied to categories. They become part of your cost basis in the home or investment property and simplify conversations with appraisers, insurers, and potential buyers.
  • Unused contingency isn’t “income.” It’s simply money you didn’t spend. In financed projects, it may reduce your final draw and long-term interest.
  • Investors: Code your contingency uses by CapEx versus repairs for depreciation and basis tracking. Clean records protect your return.

Contingency for Rental Properties and Long-Term Owners

This isn’t just for construction. Owning property without reserves is a slow-motion budget crash.

  • Operating reserve: 5–8% of gross rents for routine repairs and vacancies.
  • Capital expenditure reserve: $250–400+ per unit per year for single-family rentals, adjusted for age and systems condition. Roofs, HVAC, water heaters, exterior painting—these aren’t surprises. They’re scheduled events dressed up as emergencies when unfunded.
  • Turnover reserve: A half-month rent equivalent per turnover for paint, patching, cleaning, and minor upgrades.

Think of it as the same discipline at a different speed. Future-you will be grateful.

A Practical Checklist You Can Use

  • Before you bid:
  • Get geotechnical, survey, and necessary testing done.
  • Capture reality: exploratory demo, sewer scoping, hazard testing.
  • Price alternates and set realistic allowances.
  • Create a selections calendar with lead times.
  • Budget setup:
  • Set base contingency: 10–12% new build; 15–20% reno.
  • Add owner upgrade reserve: 2–4%.
  • Add carry reserve: 1–3 months of housing/interest.
  • Keep contingency, owner upgrades, and allowances separate.
  • Contracts and controls:
  • Define change order markup caps.
  • Clarify contractor vs. owner contingency and usage rules.
  • Pre-approve unit prices for common unknowns.
  • Establish approval thresholds and documentation flow.
  • During construction:
  • Review the change order log weekly.
  • Approve only documented, categorized uses of contingency.
  • Lock selections per calendar to protect schedule.
  • Reforecast the contingency balance at each milestone (post-foundation, post-rough, pre-finishes).
  • If things tighten:
  • Prioritize structure, waterproofing, and MEP quality.
  • Defer non-critical finishes or alternates.
  • Use value engineering intelligently, not bluntly.

The Quiet Upside of a Well-Funded Contingency

The best part of carrying a contingency isn’t just avoiding disaster. It’s the freedom to choose well. You can say yes to the right fix rather than the quick fix. You can approve the framing correction the inspector requests without grinding the job to a halt. You can keep relationships strong because you’re not negotiating from scarcity on every decision.

There’s a financial return too. Finished projects with fewer compromises sell better, appraise cleaner, and live more comfortably. They also maintain their integrity long after the paint dries, because the money went to the bones and the details, not just the visible shine.

I’ve never had a client call me years later and say, “I wish we’d carried less contingency.” But I have a long list of folks who wish they’d had the buffer to keep the project they wanted, instead of the one they settled for when the budget cracked.

Set the reserve. Treat it with respect. Then build with confidence and fewer surprises. That’s how you protect your project, your money, and your sanity.
