Keep Your Family Warm and Safe—No Matter What

It's restricted, not outright banned. BAAQMD Regulation 6, Rule 3 requires any new wood-burning device to be EPA-certified (open-hearth masonry fireplaces generally can't be newly installed), and the county and cities layer their own building permit requirements on top. On Winter Spare the Air days, burning is prohibited in any wood-burning device regardless of certification—that applies countywide, from San Mateo to Pescadero. A local hearth dealer who's dealt with BAAQMD compliance before is worth more here than in most counties, since the rules aren't intuitive.

Mostly climate. At 2,475 heating degree days and winter lows averaging in the mid-40s, San Mateo County's heating season is short and mild compared to almost anywhere else that burns wood for warmth. A furnace or heat pump handles the load without much strain most winters, so there's little practical case for adding a wood stove purely for heat. Add BAAQMD's wood-burning restrictions and the wildfire-smoke sensitivity that comes with living near county open space, and wood heat just never became part of the local building culture the way it is in colder, drier parts of the state.

Yes, in most cases, if the unit is EPA-certified and you get the right permits—through the city building department if you're in an incorporated city like San Mateo or Redwood City, or through the county's Planning and Building Department for unincorporated areas like La Honda or Loma Mar. Replacing an old, uncertified fireplace or stove with a certified unit is generally viewed more favorably than adding a brand-new one where none existed. A dealer familiar with BAAQMD Rule 6-3 can tell you quickly whether your specific property and appliance choice will clear permitting.

BAAQMD issues Winter Spare the Air alerts on days when regional air quality is forecast to be poor—typically during still, cold, high-pressure stretches when smoke gets trapped near the ground. On those days, burning in any wood-burning device is prohibited across all nine Bay Area counties, San Mateo included, regardless of whether your stove is EPA-certified. Violations can carry fines. If you're weighing wood heat here, plan around the fact that you may not be able to burn on exactly the days you'd want to.

For homeowners in the county's more exposed, wildland-adjacent areas—La Honda, Woodside, Portola Valley, Pescadero—this is actually the strongest local case for wood heat. PG&E Public Safety Power Shutoffs (PSPS) during dry, windy conditions can leave a property without grid power, and without power, gas furnace blowers and electric heat pumps stop working. An EPA-certified wood stove burns without any electrical input, which makes it one of the only heat sources that keeps working through a multi-day PSPS event. It's a narrower use case than climates with real winter cold, but for county residents in fire-prone terrain it's a legitimate reason to consider one.

Locally, oak, madrone, and Douglas fir are the most common species available, often from tree removal or clearing on wildland-adjacent properties in the foothill communities. Oak burns dense and long; madrone is hard and clean-burning but less commonly sold commercially; Douglas fir needs a full season or more of seasoning before it burns efficiently. Because there isn't much of a countywide firewood delivery market—unlike drier, wood-heating-heavy parts of the state—most wood-stove owners here source wood from their own property or from a small number of local arborists and tree services.

Yes. Whether you're in an incorporated city or unincorporated county land, a building permit is required for any new wood-burning device installation, and the unit itself needs to meet EPA certification standards to pass inspection under BAAQMD's rules. If you're replacing an existing, older fireplace or stove, permitting is usually more straightforward than adding a wood-burning appliance where one never existed. A local dealer who regularly pulls permits in San Mateo County will know which path applies to your specific property.

For nearly all San Mateo County homes, gas is the more practical fit: it's not subject to BAAQMD's wood-burning restrictions or Spare the Air burn bans, it doesn't depend on sourcing and seasoning firewood, and most of the county has natural gas or propane infrastructure already in place. Wood only pulls ahead in one specific scenario—as off-grid backup heat during PG&E PSPS events in wildland-adjacent communities like La Honda or Portola Valley, where a stove that doesn't need electricity has real value. If you're not in that situation, gas is almost certainly the better answer.

Because wood heat is a niche request here, not every hearth retailer in the county stocks or installs wood-burning units—many have shifted their business almost entirely to gas and electric. The dealers worth calling are the ones who can speak fluently about BAAQMD Regulation 6-3, EPA certification requirements, and Spare the Air compliance, since getting that wrong means a failed inspection or a fine. That's exactly the kind of local matching Find My Fireplace exists for—we'll only point you toward a wood-capable dealer if a wood stove genuinely makes sense for your property and situation.

Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.

An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.

If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.

On average, a fireplace adds back to the home about the same amount you spent installing it. Add the monthly savings from heating the rooms you actually use instead of the whole house—often hundreds of dollars a year—and the value case is strong before you even count what a fire does for how your family uses the room.
