Everything you need to know before, during, and after your project. California-specific advice backed by CSLB regulations and real industry data.
Hiring a Contractor
9 answersHow to verify a contractor's license in California
Every contractor working on projects over $500 in California must hold a valid CSLB license. Here's how to check and what to look for.
Red flags when hiring a contractor
Warning signs that a contractor might not be trustworthy: no license on estimate, asking for large deposits, no written contract, pressure to start immediately.
How many estimates should I get?
Get at least 3 estimates from different contractors. Compare not just price but scope, materials, timeline, warranty, and payment terms.
Money & Payments
9 answersCalifornia deposit limits: what your contractor can legally ask for
California law (B&P Code 7159.5) limits deposits to $1,000 or 10% of the contract, whichever is less. Any contractor asking for more is breaking the law.
How to structure a safe payment schedule
Never pay ahead of work completed. Tie payments to milestones: deposit, demo complete, rough inspection, substantial completion, final walkthrough.
Understanding lien waivers and why they matter
A lien waiver is your proof that you paid. Without one, a subcontractor or supplier could file a lien on your home even if you already paid your contractor.
Contracts & Legal
9 answersWhat should be in your construction contract
A good contract includes: detailed scope, specific materials, timeline with milestones, payment schedule, change order process, warranty, insurance requirements, and dispute resolution.
Change orders: when they're legitimate and when they're not
Some change orders are legitimate (hidden damage, code requirements). Others are from poor initial scoping. Know the difference.
What to do when things go wrong
Document everything. Start with a written complaint to the contractor. Then file with CSLB. Mediation and small claims court are options for disputes under $10,000.
Project Planning

Typical timeline: 2-3 weeks for design/permits, 1 week demo, 2-3 weeks rough, 2-3 weeks finish. Total: 6-12 weeks.
Bathroom remodel: costs, timeline, and what to watch for
Budget $15,000-50,000 for a mid-range bathroom remodel. Waterproofing is critical - don't let your contractor skip it.
ADU guide: California regulations, costs, and timeline
California allows ADUs on most residential lots. Typical cost: $150,000-350,000 for a detached ADU.
Permits explained: when you need them and how to get them
Most remodeling projects in California need a building permit. Your contractor should pull permits - if they suggest skipping, that's a red flag.
Inspections & Quality
6 answersWhat city inspectors look for at each stage
Inspections happen at key milestones: foundation, framing, rough (plumbing, electrical, mechanical), insulation, drywall, and final.
How to do your own quality check before final payment
Walk through every room with a checklist: paint, trim, caulking, outlets, cabinets, doors, tile, appliances. Document everything.
