Finding a reliable contractor in San Diego can be difficult when dealing with poor communication or very high bids. Building a backyard granny flat is a large project, and finding the right team for the job matters. San Diego ADU Solutions knows that homeowners need to know how to separate experienced builders from unreliable workers.
Start With the License and Bond Check
Homeowners should always verify a contractor's credentials directly. The California Contractors State License Board website allows anyone to type in a license number to check status. An active B-General Building license is required, and workers' compensation insurance must also be verified. If a worker on your property falls off a ladder and lacks insurance, the homeowner's insurance policy gets dragged into a lawsuit.
The duration of the active license should also be reviewed. If the license was issued recently under a new business name, extra caution is needed.
The Questions You Need to Ask Face-to-Face
Contractor pricing is only one part of the evaluation. Homeowners should ask how many detached secondary dwelling units the team has built within city limits or San Diego County jurisdiction. Building codes in San Diego are very specific, especially regarding local coastal commission rules and steep sloping lots in neighborhoods like La Mesa or Clairemont. The contractor must handle all city inspections rather than leaving that task to the homeowner.
- Who handles utility tie-ins and SDGE coordination?
- Do you use in-house crews or subcontractors for framing and plumbing?
- Can I visit a job site you are currently framing right now?
What a Real Estimate Looks Like
Vague quotes that lack detail should be rejected immediately. A legitimate estimate from an experienced crew like San Diego ADU Solutions breaks down line items: earthwork, foundation, framing, roofing, drywall, finishes, and allowances for fixtures. If fixture allowances are missing, homeowners will face unexpected change orders later in the process.
Payment schedules require careful attention as well. California law states that a contractor cannot request more than 10 percent down or $1,000, whichever is less, to start a residential remodeling or ADU project. Any builder demanding half down upfront should be avoided.
Red Flags That Mean Walk Away
Unmarked trucks, missing physical office addresses, cash-only payment terms, and claims that permits are unnecessary for a backyard cottage are major warning signs. San Diego building inspectors enforce strict rules regarding unpermitted construction, and tearing down illegal framing results in major financial losses.
Homeowners must trust their instincts during the process. If issues arise during the initial consultation, the project will likely encounter similar problems during construction. San Diego ADU Solutions provides ADU Contractor services for homes in San Diego, CA.
