How to Choose a Patio Contractor in San Diego

Updated November 1, 2026

A patio cover, pergola or sunroom is a structure attached to your biggest investment, so who builds it matters as much as what you build. California has clear consumer protections for home improvement projects. Here is how to use them.

1. Confirm the license

In California, any project worth $1,000 or more in combined labor and materials requires a licensed contractor. That threshold rose from $500 on January 1, 2025. Look up the license number on the CSLB license lookup and check that:

• The license is active and in the business name on your quote
• The classification fits the work
• There are no current disciplinary actions
• Workers' compensation is on file if the contractor has employees. It is required by law when they do

2. Get two or three written quotes

Ask each contractor to quote the same size, style and materials so you can compare fairly. A good quote spells out the structure, roof type, color, footings, electrical work, permits, cleanup and timeline.

3. Know the payment rules

California limits what a contractor can collect up front on a home improvement job:

• Down payment: no more than $1,000 or 10 percent of the contract price, whichever is less. There is no exception for special-order materials, unless the contractor carries specific blanket performance and payment bonds.
• Progress payments: payments may not get ahead of the work actually completed.

A contractor who asks for half up front is breaking the rules, which is a red flag on its own.

4. Read the contract

Home improvement contracts over $500 must be in writing. Look for:

• A description of the work and materials, the price and a payment schedule
• Who will obtain the building permits
• Start and completion dates
• The contractor's license number, address and phone
• Cleanup and debris removal
• Warranty terms in writing, if a warranty is offered
• That any changes will be made in writing and signed by both parties

You generally have three business days to cancel a home improvement contract, or five if you are 65 or older, by giving written notice. Exceptions apply, such as contracts signed at the contractor's place of business.

5. Protect yourself from liens

Subcontractors and suppliers who are not paid can place a lien on your home, even if you paid your contractor. Ask for a list of subcontractors and suppliers, and get lien releases as each part of the work is paid for.

Red flags

• A large deposit or cash-only payment
• No written contract, or pressure to sign the same day
• Suggesting you pull the permit yourself as the owner-builder
• A license number that does not match the business name
• A price far below the other quotes with no clear reason
