How to Value a General Contracting Business in Illinois

General contracting businesses in Illinois are valued at 2x to 5x SDE or 0.3x to 0.6x annual revenue, with significant variation based on project type (residential, commercial, government), bonding capacity, backlog quality, and whether the business can operate without the owner's personal client relationships.

Backlog and Pipeline

The signed backlog — work contracted but not yet completed — is a tangible future revenue asset. A GC with $3M in signed backlog is worth more today than an identical business with an empty pipeline. Buyers will review all contracts, payment histories, and margin profiles during due diligence. Work-in-progress schedules and surety bond relationships are closely examined.

License and Bonding

Illinois contractor licensing requirements vary by municipality. The selling contractor's license may or may not be required for the buyer to operate under. Surety bonds and the bonding capacity of the business are critical for commercial contractors — buyers who lack bonding relationships or track record may need to build these post-acquisition, which affects the transition plan.

Client relationship dependency is the most common value risk in GC businesses. If major accounts are tied to the owner's personal friendships, a thoughtful transition plan and potentially an earnout tied to revenue retention may be appropriate.

How Illinois buyers put a number on how to value a general contracting business

This page is the valuation guide. It is not the sale-process playbook. Seller’s discretionary earnings (SDE) is the cash a full-time working owner can take after you normalize the books. Start with the tax return. Add owner pay and one-time costs. Subtract the wage you must pay to replace the owner.

GC recasts on backlog gross profit and a market-rate PM, not last year’s completed hospital wing. Add back owner-superintendent hours, then isolate retainage that may never collect and any job that is really the seller’s license. Bonding capacity is a cap, not an add-back. A 3x–5x SDE band assumes contracted backlog and a qualifying party who stays.

Planning band on this vertical: 3x–5x SDE. That is a range, not a quote. BizBuySell’s Q2 2026 Insight Report showed a 2.7× cash-flow multiple across all reported closed deals. Do not use that marketplace average as this shop’s appraisal.

A worked planning example (illustration)

Illustration only — not a quote for any Illinois shop. A general contractor whose tax return shows $189,000 of net profit is not worth $189,000 × a rumor multiple.

Add back the owner’s $121,000 W-2 and payroll tax, $22,500 of discretionary benefits, $9,500 of accepted one-time cost, and $9,000 of personal expenses that a buyer will not run. Then subtract $1,000 of replacement labor if the owner still diagnoses, sells, or closes the books.

Adjusted SDE in this illustration is $350,000. At 4.00x, enterprise value is $1,400,000 before debt, working capital, holdback, and tax.

SDE line items buyers actually use

1. Reported net profit (tax return, not the marketing P&L)
2. + Interest expense
3. + Income taxes (not payroll, sales, or property tax)
4. + Depreciation and amortization
5. + Owner W-2, bonuses, and payroll taxes on the owner
6. + Discretionary owner benefits that a buyer will not keep (auto, personal travel, family on payroll with no role)
7. + Accepted one-time or non-recurring expenses
8. − Market-rate replacement labor for owner work that will not transfer
9. = Seller’s Discretionary Earnings (SDE)

What moves the multiple up or down

• Contracted backlog with collectible retainage
• A staying qualifying party and PM
• Bonding a successor can keep
• Mix that is not one developer
• Clean lien and OSHA history

What does not transfer with the price

Illinois has no statewide general-contractor license, but Chicago requires a general contractor license and many suburbs register GCs. Roofing work inside the GC still needs an IDFPR roofing license. The Illinois Home Repair and Remodeling Act applies to residential. Bonding and municipal prequalification sit on the named entity and the qualifying individual — they reset when that person leaves.

Diligence that changes the number

• Backlog that is contracted versus verbal
• Who holds Chicago or municipal GC registration and any IDFPR roofing qualifier
• Bonding capacity, work-on-hand, and retainage aging
• PM and superintendent tenure
• Customer concentration among developers or public bodies
• Litigation, lien, and OSHA file

Documents to gather this week

1. Three years of signed business tax returns and matching P&Ls
2. Year-to-date P&L, balance sheet, and three months of bank statements
3. Current lease, amendments, and a plain-English remaining term
4. License and permit list, including who holds each card
5. Top-customer concentration (names redacted until an NDA)

A simple Illinois close calendar

Plan six to twelve months from cleanup to close on a prepared Main Street deal. Start CBS-1 and any Chicago or Cook notices at letter-of-intent, not the week of funding. Landlord consent often takes longer than the lender.
