Making South San Francisco Homes Work Better
Most South San Francisco homes were built in the 1950s and 60s when families lived differently. Kitchens were closed off from dining rooms because cooking smells needed to stay contained. Bathrooms were tiny because people spent less time getting ready. Single-car garages made sense when most families owned one vehicle.
Nobody planned for home offices, open entertaining spaces, or rental units in the backyard. The electrical systems can’t handle modern appliances without tripping breakers. Small bathrooms feel cramped when multiple people need to get ready for work. Closed-off kitchens isolate whoever’s cooking from family conversations.
Your home should work for how you actually live today – whether that means opening up walls for better flow, converting unused space into income-generating ADUs, or updating systems that struggle with modern demands. We handle the construction work that makes South San Francisco homes more functional, more comfortable, and more valuable.

Romy Construction fully remodeled a guest cottage with kitchen and bath in 2024 for us in San Francisco. The quality, the efficiency, the price and the communication all the way through were just great. Everything we asked for and more, all our ideas came alive in the hands of his great crew. He has a great commitment to detail, but also always listened to what we needed. We picked out the important materials (tile etc) and he provided the rest. We couldn't be happier. All thumbs up for Romy Construction! Irel Can2024-11-08Trustindex verifies that the original source of the review is Google. Buenas obras les recomiendo. Koorosh Davoodian2024-08-28Trustindex verifies that the original source of the review is Google. The wood on my balcony was aging and needed repair. I also wanted to replace the railing with metal. I had a specific design in mind, and Romy was able to build exactly what I wanted. His team worked tirelessly every day, even over the weekend, to get the project done. He paid attention to every little detail. Not only did he get the details right, he also made great suggestions along the way. The work was done quickly, yet carefully. The update elevated our house to the next level. Thanks Romy! Raquel V2024-08-10Trustindex verifies that the original source of the review is Google. All the past torrential rainstorms over the years had left our deck and staircase crumbling from dry rot. Several google searches and a bit of research later, I am so happy we found this guy! Romy and his team do excellent work and he’s fast. From start to finish, he was professional and communicative with the details of our project. He came in with the estimate by the next day, explained the details, then they showed up the following week to start. He was on time everyday, organized with the lumber & deliveries, and kept the work area spotless before they left each day. With our needs and his recommendation, we decided on Trex, because there’s little to no maintenance needed for years. Our deck is so beautiful now and we are happy customers. Thanks Romy! Austin Hwang2024-07-08Trustindex verifies that the original source of the review is Google. Romy did an amazing job helping us take down our wall and lay new flooring in our living room. He was incredibly thorough, efficient, and communicative. Cannot recommend him enough - we will definitely be relying on him for future projects. We reached out to several contractors for quotes and romy was the most affordable. He got started right away and finished within 2 weeks.

Kitchen Remodeling
Your kitchen probably has that galley layout with walls separating it from the dining room. Or cabinets that don't reach the ceiling, wasting storage space. Maybe the electrical can't handle modern appliances without tripping breakers.
We handle the layout changes that make kitchens work better. Removing walls to create open space. Adding islands for extra prep area and storage. Updating electrical panels so you can run the dishwasher and microwave at the same time.
Cabinet installation includes soft-close doors and full-extension drawers that actually use all the space inside. Quartz countertops that don't stain when you spill wine. Tile backsplashes that are easy to clean after cooking.
The city requires permits for electrical and plumbing changes. We handle the paperwork and coordinate inspections so your project doesn't get delayed.
Bathroom Renovations
Small bathrooms are common in South San Francisco homes. You're probably dealing with a pedestal sink that offers zero storage. A bathtub nobody uses taking up half the room. Medicine cabinets that barely fit your toothbrush.
Tub-to-shower conversions give you more floor space and easier access. Walk-in showers with built-in niches for shampoo bottles. Vanities with drawers for all the stuff that used to sit on your counter.
We also handle the accessibility modifications that make bathrooms safer as you get older. Grab bars that are properly anchored into studs. Curbless showers that don't require stepping over anything. Non-slip flooring that looks good but prevents falls.
Tile work includes waterproofing behind shower walls - the kind that prevents mold problems down the road. Plumbing updates that improve water pressure and temperature control.

Complete Home Updates That Make Sense
Some houses need more than single-room updates. The electrical panel that sparks when you flip switches. Plumbing that loses pressure when someone flushes the toilet. Heating systems that leave some rooms cold while others are too hot.
We coordinate these whole-house improvements so you don't have walls torn open multiple times. Electrical panel upgrades that handle modern electrical loads. Plumbing re-piping that improves pressure throughout the house. HVAC systems that actually heat and cool evenly.
Room additions make sense when you need more space but like your neighborhood. Master suite additions with private bathrooms. Family rooms that give kids space to play. Home offices that separate work from living areas.
The engineering and permits for additions are more complex. We work with structural engineers and handle the city approval process from start to finish.
ADU Construction
South San Francisco allows ADUs in most residential zones. That means you can build a separate unit in your backyard or convert your garage into rental space. With Bay Area rents, a small ADU can bring in $2,000-3,000 per month.
Detached ADUs work well for larger lots. We handle foundation work, electrical service upgrades, and utility connections. The city requires separate water and electrical meters for most ADU types.
Garage conversions cost less but need proper insulation, heating, and sometimes ceiling height adjustments. We also handle the parking replacement requirements - you can't eliminate required parking spaces without city approval.
Basement conversions work if you have enough ceiling height and can add proper egress windows. These projects often need waterproofing and drainage improvements.
The permit process takes 2-3 months in South San Francisco. We handle plan submissions, engineering requirements, and inspection coordination.

Exterior Work and Outdoor Living Spaces
South San Francisco gets more wind and fog than other Bay Area cities. Your house needs siding and roofing that handles moisture without rotting or warping, plus outdoor spaces that work in this climate.
Fiber cement siding lasts longer than wood and doesn't need repainting every few years. Composite roofing handles wind better than asphalt shingles. Dual-pane windows reduce condensation and improve heating efficiency.
Your backyard probably has potential you're not using. Composite decking doesn't splinter or require annual staining like wood. It costs more upfront but saves maintenance time and money over the years. We include proper drainage underneath so water doesn't pool and cause problems.
Privacy fencing blocks wind and creates usable space for barbecues and family gatherings. Cedar and redwood naturally resist moisture and insects common in the Bay Area. Concrete patios work well for dining areas and fire pits with proper excavation and drainage that prevents cracking during wet winters.
We also handle the maintenance that prevents bigger problems - gutter cleaning and repair, deck staining that prevents wood rot, and caulking around windows and doors that keeps water out of your walls.
Some South San Francisco neighborhoods have HOA requirements for exterior colors and materials. We know which areas have restrictions and help you choose options that get approved. The city requires permits for decks over 30 inches high and fences over 6 feet. We know the setback requirements and handle the paperwork.

Frequently Asked Questions
Common questions about our kitchen, bathroom, and home remodeling services in South San Francisco and the Bay Area.
Most kitchen projects take 3-6 weeks depending on layout changes and permit requirements. Simple cabinet and countertop updates finish faster. Projects that move plumbing or remove walls need city permits and take longer. We give you a realistic timeline upfront and keep you updated if anything changes.
Yes, but you need to meet parking replacement requirements and ceiling height minimums. Most garage conversions need insulation, proper heating, and sometimes foundation work. The city requires separate electrical meters for most ADU types. We handle the permit process and help you understand what's required for your specific property.
Depends on what you're changing. Moving plumbing or electrical requires permits. Simple fixture replacements usually don't. If you're removing walls or changing the layout, you definitely need city approval. We handle permit applications and know which projects require inspections.
Fiber cement lasts 25-30 years without major maintenance. Wood siding needs repainting every 5-7 years and can rot in Bay Area moisture. Fiber cement handles wind and fog better than wood materials and doesn't attract insects or rot from moisture.
Some South San Francisco neighborhoods have color and material restrictions. We know which areas have HOA requirements and help you choose options that get approved. We can also attend HOA meetings if needed to explain your project and get faster approval.
Whole-house projects require more coordination but let you update everything at once. We handle structural changes, electrical and plumbing upgrades, and finish work in phases so you can stay in your home during most of the construction. The timeline depends on how much you're changing.
