Common Questions
What homeowners ask
What license does a general contractor need in California?
General contractors must hold a Class B (General Building Contractor) license from the CSLB. For kitchen remodels that include electrical or plumbing, they either hold those sub-licenses or hire licensed subcontractors.
Do I need a permit for a kitchen remodel?
Most kitchen remodels that involve moving walls, electrical, or plumbing require permits. A cosmetic remodel (new countertops, paint, cabinet refacing) may not. Your contractor will advise you during the estimate.
What is an ADU?
An Accessory Dwelling Unit is a secondary housing unit on your property — attached to your home, above a garage, or a detached backyard cottage. California's ADU laws have become very permissive; many homeowners are adding ADUs for rental income or family housing.
Can I get natural stone countertops from Mexico?
Yes. For kitchen and bathroom remodels, NexaBuilder can source natural stone countertops, backsplash tile, and custom finishes imported from Mexico. Available per project request for qualifying builds.
