Frequently Asked Questions
Common questions about our kitchen, bathroom, and home remodeling services in San Mateo and the Bay Area.
Yes, most kitchen and bathroom renovations require permits, especially if you're moving plumbing, electrical, or walls. We handle all permit applications and inspections. Simple fixture swaps usually don't need permits, but anything involving plumbing or electrical changes does.
Most kitchen renovations take 4-6 weeks from demo to completion. Timeline depends on cabinet delivery, any structural changes, and permit approval time. We'll give you a realistic schedule before starting and keep you updated if anything changes.
Depends on your specific lot and setback requirements. San Mateo County has minimum setback rules, but we can often work with tight spaces. Junior ADUs (JADUs) are good options for smaller properties since they're built within your existing home.
ADUs are separate dwelling units with their own utilities and kitchen. JADUs are smaller units within your existing home that share some utilities but have separate entrances. JADUs are less expensive to build and work well for family members.
Yes, but we determine what's load-bearing first and get proper engineering when needed. Removing the wrong wall can be expensive to fix, so we always check before cutting. Structural changes require permits and inspections.
Deck costs vary based on size, materials, and site conditions. Composite decking costs more upfront but lasts longer with less maintenance than wood. We provide detailed estimates that include permits, structural work, and materials.
