Fast, Reliable General Contractor Across Broadmoor
Most Broadmoor homeowners who call us are standing in a house that has outgrown its floor plan, or they’re looking out the back window at an open lot that could hold a shop, an ADU, or an addition, but they don’t know where the county will actually let them build. That’s where we come in. Timberline Contractors handles the whole job: San Mateo County permits, septic and well setback scoping, grading and drainage, framing, finishes, and the final county inspection sign-off. If you’re planning a remodel, addition, or detached structure on your Broadmoor lot, call (866) 253-5808 for a free estimate, and we’ll tell you straight what’s buildable before you spend a dollar on plans.
Why Timberline Contractors Is Broadmoor’s Preferred General Contractor Company
Broadmoor is a small unincorporated pocket of San Mateo County completely surrounded by Daly City, and that changes how every project gets permitted, inspected, and built. We’ve pulled county permits on Broadmoor jobs enough times to know that the septic and well setbacks, not the house footprint, often dictate where a structure can sit. Homeowners here tell us they appreciate that we don’t guess at that stuff, we survey it, scope it, and price it before quoting. Nelson Fung leads our team with a builder’s instinct for the details that blow up budgets when they’re missed, from fog-damp lumber to county site-plan review timelines. When a Broadmoor customer references a past job we did for their neighbor, we know exactly which house they mean, because this is a tight community and word travels fast.
Styles & brands we work with







Licensed General Contractor in Broadmoor
A Licensed General Contractor in Broadmoor manages the whole project under one contract: county permit submittal, site work, framing, rough-in, finishes, and the county inspection that closes the job. On an acreage parcel, that scope frequently expands to grading, drainage, septic and well setbacks, and long material hauls that a city contractor never thinks about. We scope that work first. A home addition in Broadmoor typically runs $45,000 to $130,000, and an ADU construction project falls between $90,000 and $220,000, depending on site conditions and finish level.
County Permitting and Site Scoping
San Mateo County’s building department reviews Broadmoor projects, not Daly City’s. That means site plans, setback verifications, and grading and drainage plans get county-level scrutiny, and a parcel that looks flat from the road can fail a site review on slope or drainage. We handle that before quoting so the number we give you holds.
Grading, Drainage, and Equipment Access
Open acreage lots rarely have staging room or a clean equipment path. If we can’t get a concrete truck or a framing crew’s load in without cutting a temporary road, that’s a line item, not a surprise. We walk the lot with you, check the slope and the soil, and put the access plan in the estimate.
Residential General Contractor in Broadmoor
A Residential General Contractor in Broadmoor handles the homes people actually live in here: post-WWII stucco-over-wood-frame houses packed tight against neighbors, with converted garages and in-law units everywhere. A kitchen remodel in Broadmoor runs $14,000 to $45,000, a bathroom remodel $9,000 to $28,000, and a garage conversion $30,000 to $80,000, but the numbers only mean something after we’ve looked at your framing, your stucco, and your lot lines. Dense side-by-side lots mean scaffolding and exterior work often land inches from a neighbor’s wall, and that changes access, protection, and sometimes the sequence of the whole job.
Stucco, Roofing, and the Marine Envelope
Broadmoor sits on the foggy, wind-exposed Pacific side of the Peninsula. Persistent marine moisture and salt air chew through exterior paint, siding fasteners, and roofing faster than homeowners expect, so we inspect the full envelope before quoting any interior remodel. A leaking wall behind a kitchen cabinet will eat the new cabinet, and we’d rather find it before we hang it.
Dense-Lot Sequencing
When your house is four feet from your neighbor’s, exterior work has to be sequenced carefully. We schedule stucco repairs, window replacements, and any scaffolding around the neighbor’s access and the county’s inspection windows. One contractor handling every phase means that sequence doesn’t slip between trades.
Trusted Brands We Service in Broadmoor
We don’t hand you a three-ring binder of third-tier options and call it a day. Our team works with over 50 brand partners across cabinetry, countertops, roofing, windows, plumbing, fencing, hardscaping, and prefab construction. For Broadmoor’s marine exposure, we lean toward GAF, CertainTeed, and Owens Corning roofing systems that hold up to wind-driven moisture and salt air. Inside, we bring the showroom to the project, with Cambria quartz, Grohe fixtures, and forty-plus other brands available without you driving to three separate design centers. We stock common parts locally for Broadmoor jobs and can usually get specialty materials staged on your lot within the county’s inspection timeline.

AfterCommon General Contractor Problems We See in Broadmoor Homes
- Quoting before the county site review. A builder quotes the building footprint, then the county flags the septic or well setback, and the pad has to move. We run the setback check first, so the quote matches the buildable site.
- Underestimating long material hauls. Broadmoor’s open lots and narrow entries mean deliveries take longer, and fog-damp lumber needs covered staging. We build that into the draw schedule, not the change-order column.
- Treating grading and drainage as an afterthought. A sloped Broadmoor lot that drains wrong will undermine an outbuilding slab in one winter. We scope drainage before concrete, always.
- Marine moisture on the envelope. Stucco and roofing details that work inland fail here in five years instead of fifteen. We specify fasteners, flashing, and sealants for salt air, not for the Bay Area average.
Pricing for General Contractor in Broadmoor, CA
Broadmoor pricing reflects two realities: county-level permit and inspection requirements, and site conditions that range from dense side-by-side lots to open acreage with septic and well constraints. The table below gives you honest ranges for the work we do most here. What moves the number: setback corrections, drainage work, equipment access, material haul distance, and finish selections. A Cambria countertop upgrade costs more than a standard quartz, and we’ll show you both numbers before you choose. Call (866) 253-5808 for a free estimate, and we’ll give you a written line-item quote that covers the site scope, not just the structure.

FAQs About General Contractor in Broadmoor
Broadmoor is an unincorporated pocket of San Mateo County (ZIP 94015) completely surrounded by Daly City, so the county building department, not Daly City’s, issues your permits and sends inspectors. That changes everything from setback calculations to plan review timelines, and you need a contractor who has worked that system enough times to submit plans that pass review without two extra cycles. Call (866) 253-5808 and we’ll check your parcel’s jurisdiction and requirements before you commit.
On a Broadmoor acreage parcel, the septic system and well clearance zones often dictate where a structure can physically sit, and they can push a planned addition or detached ADU into a different corner of the lot. We verify those setbacks with the county before quoting, then stake the pad location against the county site plan. Get your free estimate at (866) 253-5808, and we’ll tell you what’s actually buildable.
Yes, in measurable ways. Morning fog and damp wood mean we schedule envelope work, stucco and roofing, after inspections and on dry windows, and we cover stored lumber. Salt air also pushes us toward corrosion-resistant fasteners and higher-grade roofing systems from GAF, CertainTeed, or Owens Corning, which cost a bit more up front and avoid premature failure. We’ll show you those material line items in the quote, call (866) 253-5808.
Often yes, but the answer depends on septic and well setbacks, lot slope, and county site-plan approval, not on how big the structure looks on a sketch. We scoped a detached shop-and-ADU on an acreage parcel off Broadmoor Drive where the septic and well clearances, not the building footprint, set the final pad location. Call (866) 253-5808 and we’ll run the site check before you spend money on plans.
A written line-item scope that includes site conditions, grading and drainage, material haul and staging, the finish schedule, and every allowance and change order in writing before we break ground. On our Broadmoor jobs, including the detached shop-and-ADU with the Cambria countertop upgrade, every change order was documented before work started, so the punch list closed clean. Call (866) 253-5808 for a free estimate with that discipline built in.
