Design-build kitchens, bathrooms, additions, ADUs, whole-home remodels & outdoor living — one dedicated team from design through construction.
New Bay Builders serves San Francisco homeowners with full-service design-build remodeling. Our portfolio includes multiple San Francisco full-house remodels and kitchens — including projects on 36th Ave, Tiffany Ave, 43rd Ave, 44th Ave, and Silver Ave — and we bring that same one-team approach to every city project, from kitchens and bathrooms to additions, ADUs, whole-home remodels, and landscaping & hardscape.
Every project starts with a free consultation and a detailed written scope, so you know exactly what’s included before work begins. Visit our Alameda showroom — 2515 Santa Clara Ave, Suite 207 — by appointment to explore cabinetry, countertops, and finishes in person, or call (510) 295-3205 to get started.
