How Much Deposit Should a Chicago Contractor Ask For?

No City or State rule we can find sets a number. Here is how to protect yourself anyway.

Short answer

We have not found a Chicago or Illinois rule that caps a contractor deposit or sets a percentage, so be wary of anyone who quotes one as law. What you can control is the structure: a written contract, which Illinois requires for home repair over $1,000, and payments tied to work finished in stages. Pay by a traceable method, keep receipts, and treat a big demand for cash up front as a reason to slow down.

There is no deposit number we can give you, because we can't point to a City of Chicago or State of Illinois rule that sets a cap or a percentage for a Chicago contractor deposit. Anyone who says "the law says 10 percent" or "never more than a third" is giving you a rule of thumb, not a rule. What you can do is control how the money moves, and that matters more than the number.

What does Illinois actually require?

The Illinois Home Repair and Remodeling Act applies to a residence of 1 to 6 units (815 ILCS 513/10). For home repair or remodeling over $1,000, the contractor must give you a written contract or work order to sign before starting. It must state the total cost, with parts and materials listed with reasonable particularity, plus the business name and address (815 ILCS 513/15). The contractor must also give you the pamphlet "Home Repair: Know Your Consumer Rights" before you sign, and for jobs over $1,000 you sign a dated acknowledgment form (815 ILCS 513/20).

The Act does not, as far as our sources show, set a deposit amount. Our post on what your Illinois home repair contract must say goes line by line. Check the current text, and ask an attorney if you need a legal read.

How should payments be structured?

This part is practice, not law. Ask for a payment schedule that follows the work, written into the contract:

  1. A start payment that is clearly explained, such as materials ordered or permit and mobilization costs, with the contractor showing what it buys.
  2. Stage payments tied to finished milestones you can see: for a porch, say, demolition done, framing done, then guards and stairs done.
  3. A final payment held until the work is finished, any required City inspection has passed, and you have walked it with a punch list.

Ask: "What does each payment buy, and what happens if work stops?" If the answer is vague, so is the plan. Compare the structure between bids, not just the total, and see how to compare contractor estimates.

Cash and no paper

Pay by check or another traceable method, and keep every receipt. A contractor who insists on cash and won't put the payment schedule in writing is on our red flag list.

What are the warning signs on deposits?

If a contractor breaks the Act, a person who suffers actual damage can sue under the Consumer Fraud and Deceptive Business Practices Act, and the Attorney General or a State's Attorney can act on a pattern (815 ILCS 513/30). That is a remedy after the fact. Structure the payments so you never need it.

Common questions

We have not found a Chicago or Illinois rule that caps a deposit or sets a percentage. The Home Repair and Remodeling Act requires a written contract for work over $1,000 but, per our sources, does not set a deposit amount. Check the current law or ask an attorney.

There is no official number, so we won't quote one. A better test is whether the deposit is explained in writing, such as materials or permit costs, and followed by payments tied to finished stages, with the last payment held until the work is done.

Pay by check or another traceable method and keep receipts. A contractor who insists on cash and won't put the payment schedule in a signed contract is a warning sign. See our red flag list.
