Choosing a contractor is a documentation and risk-control process. A referral can identify a candidate, but it does not verify the candidate's current license, classification, insurance, availability, or fit for the work. Start with a written scope, give bidders the same information, and preserve the evidence behind the selection.
The California Contractors State License Board advises consumers to obtain at least three written bids and compare them using identical plans, specifications, and scope. CSLB also warns against automatically choosing the lowest bid. Its current contractor-selection guidance explains the checks consumers should make before hiring.
Define the work before requesting prices
A useful scope tells bidders what result is required and what conditions are known. Include the property address and work area, drawings or photos, measurements that have been verified, materials or performance requirements, access constraints, occupied-area rules, required permits, working hours, target schedule, cleanup, protection of existing finishes, and closeout documents.
Separate required work from optional alternatives. If a contractor identifies an additional condition during a site visit, issue the same clarification to every bidder still under consideration. Otherwise the prices may reflect different projects.
Verify identity, license, and classification
A license number printed on a proposal is not enough. CSLB says contractors must show their license number on business cards, bids, and contracts, but the number still needs verification. Use CSLB's official Check a License tool to review the current status and available complaint disclosure before hiring or signing.
Confirm that the business name, personnel, and license number match the party submitting the bid and contract. Review the license classification against the proposed work. If a home-improvement salesperson is involved, CSLB provides a registration lookup through the same tool. Save a dated copy or record of the verification in the project file.
Review insurance and business information
CSLB recommends verifying the contractor's business address and telephone number. It also advises asking for insurance information and checking the license history. California contractors with employees generally must carry workers' compensation insurance, subject to the rules described by CSLB. Commercial general liability insurance is different and is not universally required by CSLB.
Ask a qualified insurance professional what evidence and coverage terms are appropriate for the property and scope. Do not rely on a certificate alone to decide whether coverage is adequate, and do not assume one limit fits every project. Keep the documents and verification notes with the contract.
Compare complete written bids
Build a comparison that shows more than the total price:
- scope inclusions, exclusions, and allowances;
- materials, quantities, and substitutions;
- permit responsibility and inspection assumptions;
- schedule, sequencing, and occupied-area protections;
- payment schedule and change-order process;
- warranty and closeout requirements;
- license, insurance, references, and relevant project experience.
A materially lower bid may reflect a different scope, omitted work, an estimating error, or another explanation. Ask written questions and update the comparison. Price becomes meaningful only after the bids describe the same work.
Check references for comparable work
Ask for recent projects that resemble the property type, size, occupied conditions, and technical scope. With the reference's permission, ask whether the contractor communicated changes, managed the site, met documentation requirements, and completed punch-list or warranty items. Online reviews can provide leads, but they should not replace license verification, direct references, or contract review.
Control changes during the project
Require written change documentation before changed work proceeds except where emergency conditions require an authorized response. A change should identify the condition, revised scope, price, schedule effect, and approval. Track submittals, permits, inspections, daily or periodic progress evidence, invoices, and payments against the contract.
Closeout should match the scope. Collect final inspection records when applicable, warranties, manuals, approved substitutions, completion photos, keys or access items, lien-related documents required for the project, and a final cost record. Have counsel advise on contract language, notices, payment protections, and lien requirements.
Keep vendor selection connected to property management
The California Department of Real Estate's Property Management reference chapter lists maintenance schedules and repairs, independent-contractor license and insurance checks, estimates, purchasing, records, and owner reports among a manager's duties. The selection file should remain connected to the work order, budget, owner authorization, and completion evidence.
