Common Questions
What homeowners ask
What license does a home remodeling contractor need in California?
Remodeling contractors must hold a B-1 (General Building) license from the CSLB for projects over $500. Specialty trades (C-10 electrical, C-36 plumbing, C-20 HVAC) require their own C-class licenses. Always verify at cslb.ca.gov before signing a contract.
Do I need permits for a kitchen or bathroom remodel in LA?
Yes for structural work, electrical upgrades, plumbing changes, and ventilation. Cosmetic work (paint, flooring, cabinet replacement without plumbing changes) typically does not require permits. Your licensed B-1 contractor should identify and pull all required permits before work begins.
How long does a kitchen remodel take in Southern California?
A partial kitchen remodel (cabinets, countertops, appliances) takes 3–5 weeks. A full gut-and-rebuild typically takes 6–12 weeks. Lead time on custom cabinets and stone countertops — especially Mexican imports — often drives the overall schedule.
Can I live in my home during a remodel?
For kitchen remodels, most homeowners stay and use a temporary kitchen setup. For master bath remodels, staying is usually fine if you have a secondary bathroom. For whole-home remodels or major structural work, temporary housing for 2–6 months is often more practical and cost-effective.
