Keep Your Family Warm and Safe—No Matter What

In almost all cases, no. BAAQMD Regulation 6, Rule 3 has banned installing new wood-burning fireplaces in new construction and major remodels since 2015, and this applies citywide across every Palo Alto zip code from 94301 to 94306. The only wood-burning appliances still permitted are EPA Phase 2-certified wood stoves or inserts installed into an existing, already-approved masonry chimney, plus pellet stoves in rare cases. If you're building new or doing a full remodel, a gas or electric fireplace is the standard path—both remain unrestricted.

Yes, it applies to every household in Santa Clara County, including Palo Alto. From November 1 through February 28 each year, BAAQMD issues a Spare the Air Alert on days when fine particulate pollution is forecast to reach unhealthy levels. On those days, burning wood in any device—fireplace, wood stove, or insert, certified or not—is illegal, with fines starting around $100 for a first violation. The only exemption is for homes registered with BAAQMD as having no other adequate source of heat, which is essentially nonexistent in Palo Alto given how thoroughly PG&E's gas and electric service covers the city.

You can use an existing, uncertified masonry fireplace on non-alert days, but many Palo Alto homeowners choose to retrofit it instead. Installing an EPA Phase 2-certified wood stove or insert into your existing chimney is still allowed under BAAQMD rules and cuts particulate emissions dramatically compared to an open masonry fireplace, sometimes by 90 percent or more. It also gives you a legal, permitted path to enjoy the fireplace on non-alert days, and BAAQMD has periodically run wood stove change-out incentive programs offering a rebate toward replacing an old uncertified unit.

Because most local projects involve retrofitting an existing masonry fireplace rather than building new venting from scratch, costs typically run $6,000 to $12,000 for a certified insert, chimney liner, and permit—on the higher end of national averages, reflecting Bay Area labor rates and the added step of BAAQMD compliance documentation. A dealer familiar with the City of Palo Alto Development Services permitting process can give you a firm number after inspecting your chimney and confirming it can be relined and vented to code.

Two reasons: climate and regulation. Palo Alto has a mild, short heating season with an average winter low of 39°F, mild enough that central gas or heat-pump systems handle nearly all heating needs without any supplemental wood heat. Compare that to a genuinely cold-climate city like Duluth, MN, which has a much longer, harder winter heating season and where a wood stove can serve as real backup heat during outages. On top of that, BAAQMD's wood-burning rule and Spare the Air restrictions mean most homeowners who want the occasional fire find a gas insert easier to live with day to day.

Oak, madrone, and Douglas fir are the most common species sold by Peninsula and South Bay firewood suppliers, with oak generally preferred for its longer, steadier burn. Because Spare the Air alerts can be called on short notice throughout the winter, most Palo Alto wood-burning households keep a smaller stock on hand for occasional fires rather than laying in the multi-cord winter supply you'd see in a colder climate.

Yes, periodically. BAAQMD has run wood stove and fireplace change-out programs offering incentives, sometimes several hundred dollars, toward removing an old uncertified device or replacing it with a cleaner option, including EPA-certified wood inserts, gas inserts, or electric fireplaces. Funding and availability vary year to year, so check the district's current program status before budgeting one into your project.

Santa Clara County is designated a non-attainment area for particulate matter, meaning the region already struggles to meet federal air quality standards, which is part of why BAAQMD regulates wood smoke so tightly. Add regular wildfire smoke events from August through October, and Palo Alto residents are often breathing compromised air for several weeks a year before a single wood fire is lit locally. That combination is a big part of why the district treats wood burning as an exception to manage carefully rather than a default heating choice.

For nearly all Palo Alto homeowners, gas or electric is the more practical choice: both are unrestricted by Spare the Air rules, don't require a masonry chimney, and suit the city's mild climate and reliable PG&E-served grid. Wood makes sense in a narrower case: you already have an existing, code-compliant masonry chimney and specifically want the experience of a real wood fire for occasional use, understanding the Spare the Air restrictions that come with it. If that's you, an EPA-certified insert is the only appliance that keeps you compliant; if not, a gas insert or electric fireplace gives you flame and ambiance without the permitting hurdles.

New wood stoves are 70%+ efficient, so far less heat goes up the flue—which also means less draft to get a fire established. The rule: build a genuinely hot fire for about 45 minutes before you choke it down. Skip that and you get smoke in the room, creosote in the chimney, and a fire that never takes off. Most performance complaints trace straight back to this.

An insert is a fireplace that slides into a pre-existing wood-burning fireplace—if you don't have one, there's nothing to insert it into. A zero-clearance fireplace is built into a framed wall, which makes it the answer for remodels and new construction. Simple test: existing masonry fireplace means insert; blank or framed wall means zero-clearance.

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.

It's a visit where a hearth professional measures your space, confirms the model you picked actually works in your home, and walks the specs—framing, gas line, venting, finish work—before anything is ordered. Some details you just can't know until you see the house. Never make a down payment without one; it's the single most-skipped step that burns buyers.
