FOUNDATIONS ESTIMATING.

Chicago foundation contractors: go from site walkthrough to priced bid in 8 minutes. Built for Illinois soil, frost, and permit requirements.
§ Chicago fast facts

QUICK ANSWERS.

Do I need a permit for foundation crack repair or underpinning in Chicago?

Yes. The Chicago Department of Buildings requires a building permit for any foundation alteration that affects the structural load path, including underpinning and helical pier installation. Cosmetic crack filling may not require a permit, but any structural repair does. Confirm scope with the DOB before pricing a job as permit-exempt.

Does Chicago have special soil investigation requirements for foundation work?

Chapter 18 of the Chicago Building Code governs soils and foundations. Larger or more complex projects — particularly those involving underpinning adjacent to existing structures or new construction on questionable fill — may require geotechnical documentation and special inspection. Budget those line items into your bid scope before submitting.

§ Built for Chicago

LOCAL FACTS.

CHICAGO-AREA FOUNDATION CREW LABOR RATE.

$75–$110/hr depending on union vs. open-shop; Chicago Laborers Local 1 and Cement Masons Local 502 set prevailing wage rates that apply on public and many commercial projects in Cook County.

ILLINOIS FROST DEPTH (CHICAGO AREA).

42 inches — the minimum footing depth required by Illinois Building Code for the Chicago metro, driving excavation scope and cost on every new foundation and most underpinning jobs.

CITY OF CHICAGO BUILDING PERMIT FEE (RESIDENTIAL FOUNDATION WORK).

Typically $800–$2,400 for residential foundation repair or underpinning, calculated on project valuation through the Chicago Department of Buildings; commercial projects scale higher.

§ Why foundations pros in Chicago use Estimate.Pro

THE BID ENGINE.

## Foundation Estimating in Chicago Is Not Generic Work Chicago sits on a mix of soft clay, fill, and glacial till that drives foundation decisions other markets never face. You're quoting helical piers in Bridgeport one week and underpinning a Logan Square two-flat the next. The soil bearing conditions, frost depth, and City of Chicago permit requirements all feed directly into your numbers — and a generic spreadsheet doesn't know any of that. Estimate.Pro is built for the 25 trades that actually build things, foundations included. It gives you a scoped estimate in a median of 8 minutes from walkthrough to sendable bid. --- ## What Chicago Foundation Work Actually Costs Labor rates for foundation crews in the Chicago metro run $75–$110 per hour depending on whether you're running a union shop or an open-shop crew out of the suburbs. Concrete pricing at local ready-mix suppliers has averaged $175–$205 per cubic yard in recent quarters, and that number moves with fuel and aggregate costs. Permit fees add up fast. A structural repair or underpinning project in the City of Chicago typically requires a Building Permit through the Chicago Department of Buildings, with fees calculated on project valuation — commonly $800–$2,400 for residential foundation work, more for commercial. Pulling numbers too early, before scope is locked, burns margin before the job even starts. Estimate.Pro lets you save your own material cost workspace so your ready-mix pricing, rebar, and anchor bolt costs reflect your actual supplier relationships — not national averages that don't match your Schaumburg or Cicero supply house invoices. --- ## The Frost Line Problem Every Chicago Foundation Contractor Knows Illinois Building Code sets the frost depth at 42 inches in the Chicago area. That drives footing depth on every new pour and every repair scope. When you're underpinning an existing foundation that was originally footed too shallow, the remediation scope — and the cost — changes fast. When you walk a job with the Estimate.Pro app, AR measurement on supported devices lets you capture dimensions live. Camera and photo measurements are marked as estimates so you never confuse field-verified numbers with preliminary data. The scope-of-work output accounts for the line items you define: excavation depth, footing dimensions, pier spacing, waterproofing membrane, drain tile. --- ## Underpinning, Crack Repair, New Construction — Different Scopes, Same Tool Foundation contractors in Chicago quote across a wide range of project types: - **Underpinning and helical pier installation** for settling two-flats and coach houses - **Waterproofing and drain tile** in older Bungalow Belt basements - **New poured-wall foundations** for infill construction on Chicago's 25-foot lots - **Crack injection and structural repair** for limestone or brick foundation systems in greystone buildings Each of these has a different material list, different labor units, and a different permit path. Estimate.Pro lets you build trade-specific line-item templates so your underpinning scope doesn't start from the same blank page as a drain tile job. --- ## Getting Paid Without Eating 3% If you're on the Free tier, Stripe Connect payments run a 3% platform fee. Upgrade to Pro at $39 per seat per month and that fee drops to 0%. For larger crews, the flat Crew plan at $399 per month covers your whole team. Elite at $79 per seat per month adds invoice export workflows and the full Stripe Connect integration — useful when you're billing a general contractor on a schedule of values for a multi-phase foundation scope. There's no credit card required to start. The Free tier is free forever. --- ## Chicago-Specific Compliance Points That Affect Your Scope The City of Chicago enforces the Chicago Building Code, which incorporates and amends the IBC. Foundation work in Chicago frequently triggers requirements under: - **Chicago Building Code Chapter 18** (Soils and Foundations), which governs bearing capacity assumptions and requires geotechnical documentation on larger projects - **Illinois Environmental Protection Act** requirements when disturbing soil near former industrial sites — relevant in areas like the West Side, South Side industrial corridors, and former rail yards being redeveloped - **City of Chicago building permit requirements** for any foundation alteration, including underpinning, that affects structural load path Scoping these line items correctly at bid time — soil borings, vapor mitigation, special inspection — is the difference between winning a profitable job and winning a money-loser. --- ## Start Bidding Sharper Today Estimate.Pro is free to start, takes no credit card, and supports foundation work alongside 24 other trades. Your first walkthrough-to-bid takes 8 minutes or less. Build your material cost workspace once, and every bid after that gets faster.
