Construction Services in Half Moon Bay, CA
If you own a home in Half Moon Bay, you’ve likely discovered that construction here doesn’t work the way it does over the hill. The Coastal Commission’s jurisdiction covers virtually every developed parcel in the 94019 zip code, which means even a modest addition or exterior alteration can require a Coastal Development Permit on top of the city’s own building permit. That dual review changes timelines, budgets, and the order you do things in. We work inside that system every week, and we answer our own phone at (877) 610-1318 when you call with questions. The crews that show up at your door are Tom Barrett’s own people, not subcontractors hired off a list. You’ll see the same faces from the first estimate to the final inspection.
Since 1998, Barrett & Sons Construction has been the owner-operated alternative to outfits that quote one price on the phone and hand you a different bill at the door. Tom Barrett publishes his name, his address, and his license number. Look them up before you sign anything. Ask anyone on your street. We’re comfortable with that.

Why Half Moon Bay Homeowners Choose Barrett & Sons Construction
Coastal construction in Half Moon Bay punishes contractors who don’t plan for what’s behind the drywall. Homes in the Old Town core and along the Highway 92 corridor are often early-1900s fishing cottages or mid-century ranch houses that have been breathing salt air for decades. You’ll hear more about that below, but the short version is this: we open walls expecting to find rot, and we write the scope accordingly before work starts. No surprise invoices later, because every scope change, every allowance, and every price adjustment arrives as a written change order before a single nail moves.
We serve homeowners in Frenchmans Creek, Ocean Colony, and the neighborhoods around Miramar and Princeton-by-the-Sea. When someone on those streets calls us, a live person answers, 24/7, not a voicemail box and not an out-of-state call center. The home team at Barrett & Sons runs background-checked, uniformed crew members on every visit. Our 90-Day Done Right Promise is written on every contract, not buried in fine print: if something isn’t right, Tom Barrett comes back and makes it right, one call. That promise means something in a small town where you’ll see us at the hardware store on Saturday.
We’re also one of the few crews working Half Moon Bay that actively likes the permit inspector. The permit inspector works for you, not for me. That’s why we have a published offer: Free Second Opinion on Any Written Estimate. Bring us any written estimate from another contractor, and we’ll tell you frankly whether it covers what your house actually needs, including the coastal-zone permit path.
Construction Services We Offer in Half Moon Bay
Kitchen Remodeling in Half Moon Bay
Half Moon Bay kitchens in older cottages often hide rot in the sill plates behind the cabinets, and salt air eats standard cabinet hardware faster than inland. We scope for those discoveries up front, and we install named brands like KraftMaid and Cambria so you know exactly what’s going into your home.

Bathroom Remodeling in Half Moon Bay
Fog and coastal humidity make bathroom ventilation a real structural issue here, not a checklist item. We’ll assess your existing venting before we open a single wall, and we’ll put the moisture mitigation plan in writing before demo starts.

Roofing in Half Moon Bay
Between the salt air, the fog drip from coastal cypress, and the wind off the Pacific, roofing in the 94019 zip code has very little in common with roofing in Hillsborough or Millbrae. We carry GAF and CertainTeed, and we use hot-dipped or stainless fasteners because anything less corrodes and fails prematurely here.

Windows & Doors
Coastal exposure means window and door flashing is non-negotiable. We install Andersen and Marvin products and we detail the openings for wind-driven rain and constant damp air, which is what actually kills window frames in Half Moon Bay.

Fence Installation
Fog, salt, and wind shape every fence decision on the coast, from post depth to fastener choice to the finish on the boards. We build fences that stay upright and don’t rust out at the hardware, and we’ll tell you honestly which materials will and won’t hold up on your street.

Driveway & Pavers
Pavers near the coast need proper base preparation and drainage because our subgrade runs wet for months at a stretch even without rain. We install Techo-Bloc and Belgard products, and we cut in the drainage the fog belt demands.

Home Additions & ADU
This is where Half Moon Bay’s Coastal Development Permit process matters most. Adding square footage in the city almost always means a dual permit path, and we’ve walked enough Half Moon Bay additions through Coastal Commission review to know where the tripwires are. We’ll tell you the realistic timeline before you sign.

We work throughout the 94019 zip code, with most of our Half Moon Bay projects falling in these areas:

Because we schedule from our San Francisco Bay Area office and keep crews local, most Half Moon Bay estimates happen within a few days of your call. The coastal zone review clocks run on their own schedule, and we’ll set those expectations honestly from the first conversation.
Why Half Moon Bay’s Climate & Housing Affect Construction
Virtually all of Half Moon Bay’s developed area falls within the California Coastal Commission’s coastal zone. What that means in practice: nearly every construction project, whether it’s an addition, a rebuild, or even a significant exterior alteration, requires a Coastal Development Permit on top of standard city permits. That dual-permit process is administered through the Coastal Commission’s San Francisco District office, and it imposes strict setback, visual, and environmental review requirements that contractors working even 8 to 10 miles inland in San Mateo County never face. We plan for that review from day one, and we write it into the scope and the schedule.
The housing stock tells its own story. Early-1900s fishing and farming cottages in the Old Town core, mid-century ranch homes along the Highway 92 corridors, and newer coastal developments near Miramar and Princeton-by-the-Sea all sit in the same persistent marine layer. We routinely open walls in older Half Moon Bay wood-framed structures and find rot in sill plates, sheathing, and exterior trim that decades of salt air have quietly advanced. Budgeting for remediation isn’t a contingency here; it’s standard practice. Fog drip from the coastal cypress and eucalyptus belt keeps rooflines and foundation perimeters wet even without measurable rainfall. That’s why we spec stainless or hot-dipped fasteners, vapor barriers, and moisture management details as the baseline, not an upgrade.

FAQs About Construction in Half Moon Bay
Most likely yes. Because nearly all of the 94019 zip code sits in the Coastal Commission’s coastal zone, additions, rebuilds, and significant exterior alterations require a Coastal Development Permit in addition to standard city permits, and even some interior remodels can trigger review if they change exterior square footage. We’ll determine your exact permit path before we write the estimate, and we pull the permits ourselves. Call (877) 610-1318 and we’ll check your property address.
The honest answer is that the Coastal Commission’s review clock adds time that inland contractors never face. A standard kitchen remodel may take 3 to 4 months, but a project requiring full Coastal Development Permit review can add 2 to 6 months or more before construction starts. We set those expectations clearly in the first conversation, and we keep you posted as the review moves. Call (877) 610-1318 and Tom will walk you through the realistic timeline for your street.
If hidden conditions surface, yes, the scope can change, but only through a written change order that you sign before any new work proceeds. In Half Moon Bay’s older housing stock, we expect rot and corrosion, so we build realistic allowances into the initial quote. An allowance that isn’t on paper is a surprise waiting for a date. We put it on paper. Call (877) 610-1318 and ask us about how we handle discovery work.
Yes, on every eligible job. The permit inspector works for you, not for me, which is exactly why I like having him on site. We pull permits, schedule inspections, and close them out before we call the job done. The last contractor most people used told them permits were optional. They aren’t. Call (877) 610-1318 and we’ll explain what your project triggers.
It’s written on every contract, not buried in fine print. If something isn’t done right within 90 days of completion, Tom Barrett comes back and makes it right, one call. It applies to every Barrett & Sons construction and remodeling job in Half Moon Bay. Call (877) 610-1318 and we’ll send you a copy of the promise in writing.

What Half Moon Bay Customers Say
"The bathroom was finished on the day he said at the start, which nobody had led me to believe was possible."
- Loretta Vanterpool"His sons run the crews and they were in our house for four months. Not once did I feel I had to be home to keep an eye on things."
- Camila Fuentes"Beautiful work and honest pricing throughout. The project ran about three weeks past the estimate waiting on the cabinets, which was the supplier rather than him, though the delay was still real."
- Genevieve Ashcombe
