Hiring the wrong contractor is the single most expensive mistake a San Diego homeowner can make on a remodel or addition. A great design and a solid budget can still fall apart in the hands of the wrong team. Before you sign anything, here’s what actually separates a reliable, licensed general contractor from a risk you’ll regret.
1. Confirm an Active California Contractor’s License
Every general contractor working in California must carry an active license issued by the Contractors State License Board (CSLB). Don’t take a business card’s word for it — look up the license number yourself on the CSLB website and confirm three things:
- The license is active, not expired or suspended
- The classification matches your project (a “B-2” contractor can perform non-structural remodeling only; a “B” General Building license is required for structural remodeling, additions, or new builds)
- The bond and workers’ compensation insurance are current
Any contractor who hesitates to give you a license number, or whose number doesn’t check out, is an automatic disqualifier.
2. Ask About Design-Build vs. Separate Design and Construction
San Diego homeowners typically choose between two models:
- Design-bid-build: You hire an architect or designer first, get a finished set of plans, then shop that design out to multiple contractors for bids.
- Design-build: One company handles design, permitting, and construction either under a single contract or in multiple phases
Design-build tends to move faster and creates a single point of accountability — there’s no finger-pointing between the designer and the builder when a change comes up mid-project. It also lets your contractor pressure-test the design against real construction costs early, before you fall in love with a plan you can’t afford to build.
3. Get Detailed Proposals, Not Ballpark Numbers
A vague one-page quote is a warning sign. A trustworthy contractor should hand you a detailed proposal that specifies what is and what is not included in the scope of work. Look for specifics on what material the contractor is providing and what material you are required to provide.. This is what lets you compare bids apples-to-apples, and it’s what protects you from “surprise” change orders once the walls are already open.
4. Look at Real, Local Projects — Not Just Photos
Anyone can post a gallery of glossy “after” photos. Ask instead:
- Can I see 2–3 completed projects similar in scope to mine?
- Can I speak with those homeowners directly?
- Have you pulled permits and passed inspections in my specific city or county jurisdiction?
San Diego County spans fifteen municipalities — City of San Diego, County of San Diego Carlsbad, Encinitas, Chula Vista, and more — each with its own permitting office and quirks. A contractor with a long track record across San Diego County will already know what your local building department expects, which can save weeks on your timeline.
5. Understand Who Manages Your Project Day to Day
Ask who will actually be on-site supervising your project, how often, and who your single point of contact is if a question comes up. Vague answers here often predict a chaotic project later.
6. Read the Contract Line by Line
Before signing, make sure the contract clearly spells out:
- Total project cost and payment schedule
- Down payment amount – California law limits down payments on home improvement contracts to $1000 or 10% of the project value, whichever is least. If your contractor is asking you for more, this may be a red flag.
- Start and estimated completion dates
- What happens if the project runs long or over budget
- Warranty terms on workmanship and materials
California law also gives homeowners specific cancellation rights and requires contracts over a certain dollar amount to include mandatory disclosures — a legitimate contractor will already have these built into their paperwork.
The Bottom Line
The right general contractor doesn’t just build well — they communicate clearly, price honestly, and know San Diego’s permitting landscape inside and out. Price Builders has been a licensed design-build general contractor in San Diego County for more than 30 years (CA License #B-667161), guiding homeowners from concept through final inspection on additions, remodels, and ADUs.
