Fast, Reliable General Contractor Across South San Francisco
Most people who call a General Contractor in South San Francisco are standing in a 1950s stucco house with a kitchen or bathroom that has stopped meeting their needs. The questions are almost always the same: what will it cost, what will we find when the walls come open, and who has responsibility for the work. Here’s our direct answer: a mid-range kitchen remodel in South San Francisco runs $16,520 to $53,100, a bathroom remodel $10,620 to $33,040, and a home addition $53,100 to $153,400. Those are real ranges calibrated to this market, and they assume surprises will be found. We’re Seaside Contractors, led by Glen Sorrento, and we have been opening walls in South San Francisco long enough to know what is behind most of them. Call (833) 589-8103 when you are ready to price your project honestly.
Why Seaside Contractors Is South San Francisco’s Preferred General Contractor Company
South San Francisco is not one housing market. It is two. The flat, grid-planned neighborhoods like Baden, Orange Park, and Sunshine Gardens hold 1940s – 1960s stucco tract homes built fast and built tight to the street. The corridor near El Camino Real and the Caltrain line has newer infill multifamily. Both require different approaches, different materials, and different permit strategies. We work both. Homeowners here tend to come to us prepared, they know brand names, and they ask whether a contractor can really deliver one accountable team rather than a patchwork of subs. That is the core of what we do.
South San Francisco customers also ask harder questions than most, because a lot of them work in biotech and life sciences. They expect documentation, written allowances, and a change-order process that respects their intelligence. We write every surprise into a supplement with photo documentation and get approval in writing before we touch it. That is how a remodel closes on schedule instead of drifting.
Styles & brands we work with
General Contractor Services in South San Francisco
General Contractor Services in South San Francisco begin with inspection, not assumption. A kitchen remodel in a Baden tract home usually involves load-bearing wall removal or reconfiguration, all-new plumbing rough-in, electrical upgrades to current code, cabinet installation, countertop fabrication, backsplash, and flooring. When a South San Francisco homeowner asks what it costs, we give ranges tied to scope, not a flat number that moves later. A full kitchen runs $16,520 to $53,100. A small kitchen remodel sits lower, at $10,620 to $23,600. Cabinet installation alone runs $4,720 to $15,340, countertops $2,360 to $7,670, and a kitchen island $3,540 to $11,800.
Whole-home and addition scope
A whole-home remodel in South San Francisco typically starts at $70,000 and runs well past $150,000 depending on square footage and structural work. A room addition runs $53,100 to $153,400. The permit matters here. Adding square footage in an older tract often means upgrading the service panel, and on some lots, it means a closer look at soil conditions before any concrete is poured.
ADU and garage conversion
South San Francisco lots in the flats tend to be rectangular and modest, which makes an attached ADU or garage conversion the practical path for many homeowners. ADU construction runs $106,200 to $259,600. A garage conversion runs $35,400 to $94,400. We handle both, including prefab ADUs through manufacturers like Abodu and Dvele.

Construction Company in South San Francisco
Construction Company work in South San Francisco carries a constraint that most neighboring cities never face. The northern flats, particularly around Baden and the eastern edge, sit directly under active SFO approach paths. Any crane or rooftop mechanical equipment on a remodel can trip FAA/SFO airspace height review. That review runs on its own clock, not the contractor’s, and it changes sequencing. We plan for it from the first site visit. A roof replacement in South San Francisco runs $9,440 to $23,600. A home addition on a lot near the approach path may need a height clearance letter before we can even set a crane date.
Structural and systems work
Older South San Francisco homes carry a specific set of hidden conditions: outdated electrical panels, undersized floor joists, cast-iron drain lines that have rusted thin, and foundation cracks from decades of bay-fill settlement. We open, document, and price before we build. That is the only honest way to run a construction contract here.
Moisture and site preparation
The fog-cooled marine layer that rolls through the gap between the Santa Cruz Mountains and the bay keeps temperatures mild but air damp for long stretches. Stucco and flashing details need to be sequenced around that dampness, not against it. On the shoreline edge, we specify corrosion-resistant fasteners and hardware as a default, because salt-laden bay air eats zinc-plated components fast. These are not optional upgrades. They are how you pass inspection and avoid callbacks.
Trusted Brands We Service in South San Francisco
South San Francisco homeowners care about what goes behind the wall and what goes on top of the counter. We use Toto and American Standard for plumbing fixtures, Schluter for waterproofing membranes and shower systems, and Sterling for solid, value-priced bath fixtures. These are not exotic lines. They are the brands that hold up in a damp coastal climate and that parts suppliers near South San Francisco keep in stock. When a fixture or membrane fails during a renovation, waiting on a backorder means a stalled job. Our brand partnerships mean we can spec and source without that delay.

AfterCommon General Contractor Problems We See in South San Francisco Homes
- Cloth-wrapped wiring and outdated panels. Homes built in the 1940s and 1950s around Baden and Orange Park often still carry original electrical systems. Once a wall is open and a permit is pulled, code requires upgrades, and that cost is real.
- Failed shower-pan membranes. A 1950s bath with a tile shower is often hiding a rotten subfloor under a membrane that gave out years ago. We see this constantly in South San Francisco tract homes.
- Stucco that traps moisture. The marine layer keeps stucco damp, and poorly detailed flashing at roof lines and windows lets water get in and stay in. We open these assemblies carefully and rebuild with proper drainage planes.
- Corrosion on bay-fill edge lots. Homes near the shoreline deal with salt corrosion on exposed fasteners, hardware, and even structural connectors. We specify stainless or coated hardware there as a standard practice.

FAQs About General Contractor in South San Francisco
Because most 1940s – 1960s tract homes in South San Francisco still contain cloth-wrapped wiring, undersized framing, or failed waterproofing that is invisible until the wall is open. Once a permit is pulled, code requires electrical and structural upgrades, and those are mandatory costs, not optional extras. On a 1950s stucco cottage off Baden Avenue, our crew opened a kitchen wall for a load-bearing reconfiguration and found cloth-wrapped wiring and a subfloor that had been rotting under a failed shower pan in the adjacent bath. We stopped, wrote a supplement with photo documentation, and got written approval before proceeding. That is why we write allowances into every contract. Call (833) 589-8103 for a detailed quote that plans for what is behind the wall, not against it.
Most interior kitchen and bath remodels do not trigger FAA/SFO airspace review, because no crane or rooftop equipment is involved. The review becomes relevant on projects with cranes, rooftop mechanical units, or structural work that changes rooflines in the northern flats under the approach paths. If a crane is needed, the review runs on its own schedule and must be resolved before scheduling. We identify that requirement during the first site visit, not after permits are pulled. Call (833) 589-8103 and we’ll tell you early whether your project has an airspace trigger.
A real General Contractor in South San Francisco puts the following in writing before work starts: a fixed scope of work, line-item pricing with allowances for unknown conditions, a draw schedule tied to completed milestones, written change orders for every surprise with photo documentation, and a workmanship warranty. If a contractor here will not put allowances and change-order procedures in the contract, walk away. That contractor is planning to price the job on the fly. Call (833) 589-8103 and we’ll show you our contract format before you sign anything.
On shoreline-edge homes in South San Francisco, we specify stainless or coated fasteners and hardware as a standard, and we sequence stucco and flashing work around the fog cycle so assemblies dry properly. Zinc-plated hardware corrodes fast in salt-laden bay air, and trapped moisture in a stucco wall means rot and mold that do not surface for years. Moisture-tolerant assemblies are not an upgrade here; they are the difference between a remodel that lasts and one that fails at the five-year mark. Call (833) 589-8103 for a moisture assessment on your specific lot.
Yes, and on most South San Francisco lots in the flats, a garage conversion or attached ADU is the most practical path to added square footage. A garage conversion runs $35,400 to $94,400. Full ADU construction runs $106,200 to $259,600, including prefab options through Abodu, Dvele, and other manufacturers. Lot coverage, setbacks, and soil conditions on bay-fill edge lots all need to be checked before design is finalized. Call (833) 589-8103 and we’ll walk your lot with you.
