4.1 Home Improvement Contract (HIC) Requirements & Mandatory Disclosures
Key Takeaways
- Any home improvement job on a 1-4 unit residential property where combined labor and materials exceed $500 requires a written Home Improvement Contract (HIC) under Business & Professions Code §7159.
- Down payments on an HIC can never exceed $1,000 or 10% of the total contract price, whichever is less, and the cap must be printed in the contract in bold type.
- Homeowners have a statutory right to cancel an HIC until midnight of the third business day after signing, extended to the fifth business day for senior citizens age 65 and older, under Civil Code §§1689.6-1689.7.
- Every HIC must include a verbatim Mechanics Lien Warning, the contractor's license number, and a description of materials and equipment; omitting required terms is a misdemeanor under §7159.5.
- New construction of a dwelling, projects of $500 or less, and most subcontracts between a direct contractor and a specialty subcontractor are exempt from HIC requirements.
Home Improvement Contract (HIC) Requirements & Mandatory Disclosures
California regulates residential remodeling and repair work through Business and Professions (B&P) Code §7159, the Home Improvement Contract (HIC) statute. This law applies to every trade classification licensed by the California Contractors State License Board (CSLB), including C-20 HVAC contractors, and it is one of the most heavily tested topics on the Law & Business exam's Contract Requirements and Execution domain (21% of that exam).
When a Written HIC Is Legally Required
B&P Code §7159 broadly defines home improvement as repairing, remodeling, altering, converting, or modernizing a residential building or the property around it. For a C-20 contractor, this covers everything from installing a new central air-conditioning system to replacing a furnace, adding ductwork, or converting a home to a heat pump.
A written HIC is mandatory whenever:
- The work is performed on a residential structure of one to four units (single-family homes, duplexes, triplexes, or fourplexes), and
- The aggregate contract price — combined labor and materials — exceeds $500.
If the job is $500 or less, or if it qualifies under the narrower service and repair contract rules covered in Section 4.2, the full HIC paperwork is not required. New construction of a dwelling built for first sale, and subcontracts between a direct contractor and a specialty subcontractor where the homeowner is not a contracting party, also fall outside §7159's HIC requirements — though the direct contractor remains fully responsible to the homeowner for the finished work.
Required Contract Elements
An HIC must be a single, complete document — the core terms cannot simply be incorporated by reference to an outside document. At minimum, it must contain:
| Required Element | What It Must Show |
|---|---|
| Contractor identity | Name, business address, and CSLB license number |
| Scope of work | Description of the work, materials, and equipment, such as the manufacturer, model, and capacity of the condenser and furnace being installed |
| Total contract price | Stated in dollars and cents |
| Down payment | Dollar amount, capped as described below |
| Payment schedule | Amount of each progress payment tied to a specific phase of work |
| Start and completion dates | Approximate start date and completion date, or number of days |
| Cancellation notice | The 3-day (or 5-day senior) right to cancel, plus an attached cancellation form |
| Mechanics Lien Warning | Verbatim statutory notice, described below |
| Arbitration clause, if included | Must comply with §7191 formatting rules |
The Mechanics Lien Warning
Every HIC must display a heading titled Mechanics Lien Warning, using statutory language that explains how unpaid subcontractors, suppliers, and laborers can record a lien against the homeowner's property even after the homeowner has already paid the contractor in full. The contract must also state that once a portion of the work has been paid for, the contractor must furnish the homeowner an unconditional lien release for that portion before requesting the next payment (Civil Code §§8400, 8404).
The Down Payment Cap: $1,000 or 10%, Whichever Is Less
The most frequently tested number in this section is the statutory down-payment ceiling. Under B&P Code §7159(d)(8), a contractor cannot request or accept a down payment larger than $1,000, or 10% of the total contract price — whichever amount is smaller. The contract itself must print this rule in at least 12-point boldface type.
| Contract Price | 10% of Price | Statutory Cap (Lesser Amount) |
|---|---|---|
| $4,500 mini-split install | $450 | $450 |
| $8,000 furnace and coil replacement | $800 | $800 |
| $10,000 heat pump conversion | $1,000 | $1,000 |
| $22,000 full system and duct replacement | $2,200 | $1,000 |
Notice that once the contract price passes $10,000, the flat $1,000 ceiling always controls, no matter how large the job gets. A C-20 contractor who collects $2,500 up front on a $22,000 system replacement, reasoning that it is under 10% and can be adjusted later, has still violated §7159.
The Right to Cancel
A homeowner who signs an HIC has a statutory right to cancel the contract until midnight of the third business day after signing, under Civil Code §§1689.6-1689.7 (the Home Solicitation Sales framework incorporated into §7159). If the buyer is a senior citizen age 65 or older, that window extends to the fifth business day. The contract must include this notice in the same language used to negotiate the deal, along with a detachable Notice of Cancellation form the homeowner can sign and return.
Consequences of Getting It Wrong
Violating the HIC formatting, down-payment, or disclosure rules is a misdemeanor under B&P Code §7159.5, punishable by a fine of $100 to $5,000, up to one year in county jail, or both — separate from any CSLB license discipline. A defective HIC can also be unenforceable against the homeowner, though the statute preserves the contractor's ability to recover the reasonable value of completed work through equitable remedies designed to prevent the homeowner from being unjustly enriched.
