Home Remodeling & Construction in San Francisco, CA: Built for Victorians, Flats, and Narrow City Lots
Momentum Construction is a licensed design-build remodeling contractor (CSLB #1028128) serving San Francisco since 2017 from our base in Belmont on the Peninsula. We handle kitchens, baths, room additions, ADUs, roofing, flooring, painting, and outdoor work on the city’s older housing stock, from the Mission to the Richmond, managing design, permitting, and construction under one roof.
How long do San Francisco remodel permits actually take?
Longer than almost anywhere else in the Bay Area. Permits in San Francisco run through the SF Planning Department and the Department of Building Inspection (DBI), not San Mateo County, even for homeowners on the Peninsula border. Interior-only kitchen and bath work can sometimes move over the counter in weeks, but anything touching the building envelope, adding square footage, or sitting in an RH district often triggers a 30-day neighbor notification under Planning Code Section 311. During that window any neighbor can file a Discretionary Review and send the project to a Planning Commission hearing, which can add months. We scope projects around this reality from day one rather than discovering it mid-build.
Remodeling a Victorian, Edwardian, or Sunset row house
San Francisco’s housing stock is unusually specific: ornate Queen Anne and Italianate Victorians in Pacific Heights, the Mission, and Noe Valley; lighter, simpler Edwardian flats; and the tightly packed Sunset and Richmond row houses with shared walls and garage-level ground floors. These homes share predictable challenges – small, chopped-up rooms, narrow lots, and reliance on interior light wells for daylight in the middle of the floor plan. Our design-build approach focuses on opening up labyrinthine layouts and improving flow while preserving the original trim, casing, plaster detail, and facade character that the city protects in historic districts. Matching old-growth wood, stains, and millwork profiles is detail work we plan for, not a surprise at the end.
Can I add an ADU or legalize an in-law unit?
Often, yes. San Francisco’s ADU program applies citywide to districts that permit residential use, and the ground-floor garage or storage level of a typical flat or row house is the classic conversion candidate. We handle ground-floor and garage-conversion ADUs, additions at the rear, and the legalization of existing unpermitted in-law units through DBI’s checklist process. The local program has its own size limits and design standards distinct from the state pathway, and choosing the right track up front changes the timeline, the parking and exposure requirements, and what you can build.
Does your building need a soft-story seismic retrofit?
If you own a wood-frame building with five or more units, two or more stories, and a weak or open ground floor (typically tuck-under parking), it likely falls under San Francisco’s mandatory soft-story retrofit ordinance. Retrofit work generally stays at the first floor and is a natural moment to coordinate other improvements. We can fold structural strengthening into a broader remodel or ground-floor ADU rather than running it as a separate, disruptive project.
Full-service remodeling across San Francisco
Beyond kitchens, baths, additions, and ADUs, we handle roofing on flat and low-slope city rooflines, flooring including matching original hardwood, interior and exterior painting suited to fog, salt air, and Victorian color schemes, and outdoor hardscape, patios, and decks on the compact yards and rear lots common in Bernal Heights, Glen Park, and the Sunset.
San Francisco remodeling FAQ
Do I need a permit for a kitchen or bath remodel in SF? Almost always. Work involving structural changes, the exterior, plumbing, or electrical requires a DBI permit, and only the most cosmetic refresh avoids one.
Will my project go to a neighborhood notification or hearing? Many residential projects that change the envelope or add units trigger Section 311 notification, which opens the door to Discretionary Review. We design to reduce that exposure where possible.
Do you work in historic districts? Yes. We plan around facade preservation and the city’s review requirements for character-defining features from the start.
