A construction contract is the single most effective risk-management tool available on a California project, and the one most often signed without review. California layers statutory requirements on top of ordinary contract law: mandatory terms for home improvement work, restrictions on what indemnity clauses may say, non-waivable prompt payment deadlines, and a licensing rule that can void a contractor’s right to payment entirely. Bay Legal, P.C. drafts, reviews, negotiates, and litigates construction contracts for owners, general contractors, subcontractors, and developers throughout California.
Definition: A construction contract is the written agreement fixing scope, price, schedule, and risk allocation between parties to a building project.
I had the pleasure of working with Kelsey and she was fantastic! Her work on an agreement review was comprehensive and she went out of her way to make I understood everything.

What goes wrong when a construction contract is not reviewed?
Four failures account for most of the litigation, and all four are cheaper to prevent than to argue about:
- A non-compliant home improvement contract. A residential agreement that misses the mandatory terms can be voidable at the owner’s election and exposes the contractor to CSLB discipline.
- An unenforceable indemnity clause. A provision that violates California’s anti-indemnity statutes is void to the extent of the violation, so the risk transfer the general contractor thought it bought does not exist.
- Payment terms that ignore the prompt payment statutes. Those deadlines carry penalties and fee-shifting, and the retention protections cannot be contracted away.
- No workable change order procedure. Change orders are the most common source of construction disputes, and a contract without a clear written procedure guarantees an argument the first time conditions change.
Which contract structure fits the project?
Five structures cover almost every California project, and the choice decides who carries cost risk.
| Structure | How pricing works | Who carries cost risk | Typical use |
|---|---|---|---|
| Fixed price (lump sum) | One agreed price for the whole scope | Contractor | Residential and smaller commercial work with a defined scope |
| Cost plus | Actual costs reimbursed, plus a fixed or percentage fee | Owner | Scope that cannot be fully defined at contracting |
| Time and materials | Hourly labour rates plus materials at cost with a markup | Owner | Limited-scope or emergency work |
| Guaranteed maximum price | Costs reimbursed up to a ceiling; overruns are the contractor’s | Shared, with a cap | Commercial and institutional projects |
| Design-build | Design and construction under one entity | Design-builder | Projects favouring single-point responsibility |
What must a California home improvement contract include?
More than most contractors realise. Business and Professions Code section 7159 applies to most residential work over $500 and sets mandatory terms. The contract must be in writing and must state the contractor’s name, business address, and licence number, a detailed description of the work and materials, the total price, approximate start and completion dates, a change order form, a mechanics lien warning, notice of the owner’s right to require a payment and performance bond, and a three-day right to cancel where the contract was solicited at the owner’s home.
Two payment limits sit inside the same section. The down payment may not exceed $1,000 or 10 percent of the contract price, whichever is less. Progress payments may not exceed the value of work performed or materials delivered. Section 7159.5 imposes parallel requirements across home improvement contracts generally. Contractors who furnish a payment and performance bond are exempt from the down payment and progress payment restrictions.
Non-compliance is not a technicality. It can make the contract voidable at the owner’s election and it exposes the contractor to discipline by the Contractors State License Board.
Are indemnity provisions enforceable in California construction contracts?
Only within limits, and the limits override whatever the contract says. Civil Code section 2782 is the primary anti-indemnity statute for construction. It prohibits provisions indemnifying the promisee — usually the general contractor or owner — against liability for its own sole negligence or wilful misconduct, the arrangement generally called Type I indemnity. For residential construction, section 2782(d) goes further and voids provisions requiring a subcontractor to indemnify a builder for defect claims arising from the builder’s own negligence.
Civil Code section 2782.05, applying to contracts entered into on or after January 1, 2013, prohibits provisions requiring a subcontractor to indemnify or insure a general contractor or construction manager against claims arising from that party’s active negligence or wilful misconduct. A provision violating either section is void to the extent of the violation, whatever the drafting.
What remains available is Type II indemnity — covering the indemnitee’s passive negligence but not its active or sole negligence. Drafting to the enforceable edge of that line is the whole exercise, and reviewing the other side’s proposed clause for unenforceable terms is the mirror image of it.
What are California’s prompt payment rules on private projects?
A schedule of deadlines with penalties attached, and the retention protections cannot be waived by contract.
| Obligation | Deadline | Authority |
|---|---|---|
| Owner pays direct contractor | 30 days after a payment demand, unless otherwise agreed in writing | Civ. Code § 8800 |
| Owner may withhold on a good faith dispute | Up to 150% of the disputed amount | Civ. Code § 8800 |
| Owner releases retention | 45 days after completion of the work of improvement | Civ. Code § 8812 |
| Direct contractor passes retention to subcontractor | 10 days after receiving it | Civ. Code § 8814 |
| General contractor pays progress payment to subcontractor | 7 days after receiving payment from the owner | Bus. & Prof. Code § 7108.5 |
| Penalty for wrongful retention withholding | 2% per month on the amount withheld, plus fees and costs to the prevailing party | Civ. Code § 8818 |
Full text: § 8800 · § 8812 · § 8814 · § 8818 · § 8820 (non-waivability) · Bus. & Prof. Code § 7108.5.
What happens when work is done without a written change order?
It becomes an argument, and the contractor’s position weakens considerably. California construction contracts generally require change orders in writing and signed before the changed work begins, a requirement codified for home improvement contracts in section 7159. Work performed without one is difficult to enforce under the contract itself.
It is not necessarily unpaid. California courts recognise quantum meruit and unjust enrichment, which can allow recovery of the reasonable value of extra work where the owner directed it or knowingly accepted it. But that is a fallback theory litigated after the fact, not a contractual right. The practical guidance runs both ways: owners should insist on written change orders, and contractors should decline extra work without written authorisation.
Pay-if-paid or pay-when-paid — what is the difference?
One sets timing. The other can eliminate the right to payment altogether, and subcontractors sign both without noticing which they have agreed to.
A pay-when-paid clause treats the owner’s payment to the general contractor as the timing mechanism for payment down the chain. It establishes a reasonable time for payment; it does not make the owner’s payment a condition of the subcontractor’s right to be paid. A pay-if-paid clause makes the owner’s payment a condition precedent — no payment from the owner, no right to payment at all. Enforceability turns on how clearly the contract expresses the condition, and a subcontractor facing a genuine pay-if-paid clause on a project where the owner defaults may have no contractual claim.
Can a licensing lapse cost a contractor the right to payment?
Yes, and the rule is strict. Under Business and Professions Code section 7031, a contractor who was not duly licensed at all times during performance cannot bring an action to recover compensation for that work. California courts have applied it where the lapse was brief and inadvertent. The section also permits the owner to recover compensation already paid.
Two practical consequences. Contractors should treat continuous licensure as an operating requirement rather than an administrative one, and verify it for every subcontractor. Owners should confirm licence status through the Contractors State License Board before signing. Construction contracts should carry representations and warranties on licensure for exactly this reason.

Frequently Asked Questions
What must a California home improvement contract include?
Business and Professions Code section 7159 requires most residential work over $500 to be in writing, with the contractor’s name, address, and licence number, a detailed description of work and materials, the price, approximate start and completion dates, a change order form, a mechanics lien warning, and a three-day cancellation right where solicited at the home. Down payment is capped at $1,000 or 10 percent, whichever is less.
Are indemnity provisions in California construction contracts enforceable?
Only if they comply with Civil Code sections 2782 and 2782.05. California voids Type I indemnity requiring a party to indemnify another for that party’s sole negligence or wilful misconduct. Section 2782(d) additionally voids subcontractor indemnity for a builder’s own negligence on residential defect claims. Type II provisions covering passive but not active negligence remain enforceable.
What are California’s prompt payment requirements on private projects?
Owners must pay direct contractors within 30 days of a payment demand under Civil Code section 8800, release retention within 45 days of completion under section 8812, and contractors must pass retention to subcontractors within 10 days under section 8814. Late retention carries a 2 percent monthly penalty plus fees under section 8818. These protections cannot be waived.
What happens if work is performed without a written change order?
Enforcing payment under the contract becomes difficult, particularly on home improvement contracts where section 7159 requires written, signed change orders before extra work begins. California courts do recognise quantum meruit and unjust enrichment, so a contractor may still recover the reasonable value of work the owner directed or knowingly accepted. Neither party should rely on that fallback.
What is the difference between pay-if-paid and pay-when-paid?
A pay-when-paid clause sets the timing of payment down the chain but does not make the owner’s payment a condition of the subcontractor’s right to be paid. A pay-if-paid clause makes it a condition precedent, so if the owner never pays, the subcontractor may have no contractual right to payment at all. Enforceability depends on how clearly the condition is expressed.
Can a contractor lose the right to payment over a licence lapse?
Yes. Business and Professions Code section 7031 bars a contractor who was not duly licensed at all times during performance from suing to recover compensation, and courts have applied it to brief and inadvertent lapses. The owner may additionally recover amounts already paid. Verify licensure through the CSLB and carry licensure warranties in the contract.
Should the contract require arbitration or litigation?
It depends on priorities. Arbitration is usually faster and private but offers limited appellate rights and real arbitrator fees. Superior Court litigation preserves full appellate rights but takes longer. Many California construction contracts use a tiered clause requiring negotiation, then mediation, then arbitration or litigation.
Related Questions
Does a construction contract have to be in writing in California?
Home improvement contracts over $500 must be, under section 7159. Beyond that, an oral construction contract can be enforceable, but proving its terms is the problem — and the statutory protections that depend on written terms will not be available.
Who should provide the contract, the owner or the contractor?
Whoever drafts it generally allocates risk in their own favour. That is a reason to have counsel review a contract handed to you, not a reason to refuse it. The more useful question is which provisions are negotiable.
What is a flow-down provision?
A subcontract term binding the subcontractor to obligations the general contractor owes the owner under the prime contract. It is worth reading carefully, since it can import obligations the subcontractor never saw.
Can I terminate a construction contract mid-project?
It depends on whether the contract provides for termination for cause, for convenience, or both, and on what each triggers. Terminating without a contractual basis is itself a breach, and wrongful termination claims are common.
Does the contract affect my mechanics lien rights?
Yes, substantially. Contract terms bear on notice timing, retention, and the amount claimable. Payment disputes should be handled in a way that preserves lien remedies rather than forfeiting them while negotiating.
Talk to a California construction contract attorney
Review before signature costs a fraction of the dispute it prevents, and most of what matters in a construction contract stops being negotiable the moment it is signed.
