Understanding Fixed Price Contracts: Essential Guidance for California Homeowners
At Costo Construction, we believe in building projects founded on transparency, legality, and mutual understanding. A core component of that philosophy is understanding Fixed Price Contracts—the legally mandated standard for residential construction projects in California—and the legal restrictions surrounding other contract types, such as cost-plus agreements.
The Compliant Framework for Fixed Price Contracts in California
California law explicitly regulates the types of contracts that licensed contractors can use for residential home improvements. Under Business and Professions Code § 7159.5, cost-plus contracts are prohibited for home improvement projects unless certain narrowly defined exceptions apply.
This law was enacted to protect consumers from unpredictable costs and to promote transparency. It mandates that home improvement contracts be fixed price (lump sum) agreements, which specify a total, predetermined amount for the entire scope of work.

Why Are Cost-Plus Contracts Illegal for Residential Projects?
According to authoritative construction law resources and the CSLB’s official guidance, cost-plus contracts are illegal for residential home improvements because they:
Lack transparency:** Homeowners cannot accurately predict total project costs upfront.
Encourage disputes:** Cost overruns and unexpected charges often lead to conflicts.
Create potential for abuse:** Without strict regulation, cost-plus agreements can be exploited, leading to inflated costs.
The California Contractors State License Board (CSLB) emphasizes that fixed price contracts provide the necessary clarity and protection for homeowners. They also specify that contracts must be in writing, include specific terms, and define the scope, schedule, and price.

The Critical Role of Fixed Price Contracts
The law’s emphasis on fixed price contracts underscores the importance of thorough upfront planning. To draft an enforceable fixed price contract, contractors and homeowners must:
Complete detailed design and planning before signing.
Develop a comprehensive scope of work. Enough for your contractor to set a fixed price to.
Specify materials and finishes. Information cannot be general such as “tile”. Your contractor requires specific descriptions of the tile in order to set a price to it’s supply and installation costs.
Set an anticipated schedule and a payment schedule.
This upfront work ensures that all aspects of the project are known, allowing the contractor to provide an accurate, fixed total project price.

Managing Unknowns with Change Orders
While fixed price contracts are designed for certainty, unexpected conditions or scope changes can occur. To handle these, California law permits change orders—formal written amendments to the original contract.
A proper change order must:
Be approved in writing by both parties.
Clearly specify the additional scope and costs.
Be included in the contract documentation, often with a sample change order form.
Including a sample or template change order within the contract facilitates smooth modifications and protects both parties from misunderstandings.

Essential Elements of a Legally Compliant Fixed Price Contract
A robust, legally compliant Fixed Price Contract for residential projects in California should include:
A detailed scope of work: Clearly specifying what work will be performed.
A written schedule: Outlining start and completion dates.
A fixed or lump sum price: The total project cost.
A fixed payment schedule: Payments linked to milestones or completion phases.
Disclosures required by law: Including licensing, license number, and legal notices.
These elements are mandated by California law to ensure transparency, accountability, and enforceability.

Exceptions: Commercial and New Construction Contracts
It’s important to note that California law restricting cost-plus contracts primarily applies to residential home improvement projects. Commercial construction contracts and new build contracts may still utilize cost-plus arrangements when appropriate, provided they comply with relevant laws and regulations.
