Chimney questions, answered — West Seattle.

Every year. NFPA 211, in the wording CSIA reproduces on its homeowner page, has chimneys, fireplaces and vents inspected at least once a year, used or not. Cleaning is decided by what the inspection finds, not by the calendar: for a masonry fireplace CSIA advises sweeping when the soot layer is an eighth of an inch thick.

Three plain habits. In a release dated September 21, 2026, the State Fire Marshal's Office counted six fire deaths tied to home heating sources in Washington over the prior year. It urged every household to have the chimney inspected and cleaned annually, and to carry ashes out in a metal container with a lid, kept outdoors.

The Puget Sound Clean Air Agency, not the city. The agency covers four counties, King among them, and it both issues air quality burn bans and enforces them. When it calls one, every fireplace, insert and wood stove on the West Seattle peninsula is concerned at the same moment.

Stage 1 leaves certified stoves and inserts running; Stage 2 leaves nothing. During Stage 1 a wood-burning fireplace stays cold, and so does any stove or insert without a certification label. The second stage widens the stop to certified units and to pellet stoves as well. In both stages the lone exception is a household whose exemption for having no other adequate heat was granted beforehand.

Yes. A ban halts outdoor fires fed with wood or charcoal, and Seattle Parks suspends beach fires at Alki whenever a burn ban or an air pollution alert is in effect. Outside a ban the park has its own conditions: in 2026 the beach fire season ran May 22 to September 7, fires were confined to the pits the city provides, only clean, bare, dry cordwood was accepted, and each fire had to be doused with water by 10 p.m. Sources: Puget Sound Clean Air Agency, how air quality burn bans work (https://pscleanair.gov/172/About-Air-Quality-Burn-Bans, accessed October 4, 2026); Seattle Parks and Recreation, park page for the beach at Alki (https://www.seattle.gov/parks/allparks/alki-beach-park, accessed October 4, 2026); Seattle Parks and Recreation (Parkways), 2026 summer hours notice of April 13, 2026 (https://parkways.seattle.gov/2026/04/13/seattle-parks-and-recreation-2026-summer-hours-for-alki-beach-and-golden-gardens/, accessed October 4, 2026).

The cold ones, mostly. The Clean Air Agency explains that air quality bans tend to arrive in fall and winter, when still air holds wood smoke close to the ground. Its status page shows whether a ban is running right now. A summer fire-safety ban is another instrument altogether, and it is the fire marshal who issues it.

No. The agency's exemption is for homes with no other adequate heat, and cost is not part of its test. It counts a heat source as adequate when it holds occupied rooms at 70°F, measured three feet above the floor; a furnace that does so at a high price still counts. A household that truly qualifies must file its application and hold the approval before a ban starts, and even then its chimney may show no visible smoke.

Smoke from the chimney is the evidence. WAC 173-433-150 treats visible smoke three hours after an episode is declared as proof of a violation, and it tells anyone with a fire already going to stop feeding it. An agency inspector who observes a violation writes up a Notice of Violation, addressed to whoever owns the property. The agency pages we opened give no penalty amount, so we quote none.

Yes, all year. The Clean Air Agency holds chimney smoke to 20 percent opacity; the reading is taken across six minutes in a row within an hour. Fuel is limited too: manufactured logs, or wood that is dry and seasoned. A state rule, WAC 173-433-120, names what stays out of the firebox, including garbage, treated wood, plastic, rubber, paint and chemicals. Smoke that troubles the neighbors can also be pursued as a nuisance under the agency's Regulation I, Section 9.11.

No, and you may not give it away either. WAC 173-433-100 forbids advertising, selling, exchanging or handing on a solid fuel burning device without its certification and label. The Clean Air Agency runs a recycling program instead, paying owners who turn in a working stove or insert that is uncertified or below the 2020 EPA standard. The owner removes it and delivers it to an approved recycler. Pellet stoves, prefabricated fireplaces and brick fireplaces are not eligible.

The 2021 Seattle Residential Code. SDCI describes it as the 2021 International Residential Code carrying Washington State and Seattle amendments, and it applies to one- and two-family houses and to townhouses of up to three stories; its Chapter 10 deals with chimneys and fireplaces. The next edition is not close: SDCI says the 2024 Seattle codes will not be adopted before May 2027. Sources: Seattle Department of Construction and Inspections (SDCI), Residential Code page (https://www.seattle.gov/sdci/codes/codes-we-enforce-(a-z)/residential-code, accessed October 4, 2026); SDCI, Seattle Residential Code (2021 edition), tenth chapter on chimneys and fireplaces (https://www.seattle.gov/documents/Departments/SDCI/Codes/SeattleResidentialCode/2021SRCChapter10.pdf, accessed October 4, 2026); SDCI, Seattle code adoption page (2021 codes, 2024 cycle) (https://www.seattle.gov/sdci/codes/changes-to-code/2021-seattle-code-adoption, accessed October 4, 2026).

No, as long as the building envelope stays as it was. Section R105.2 of the Seattle Residential Code places chimney repointing on its list of minor work exempt from a building permit, and SDCI's remodel page says the same. The section also exempts small repairs under a value ceiling it sets over six months, provided no loadbearing support is touched. Separate mechanical, electrical or plumbing permits can still apply. Sources: SDCI, 2021 Seattle Residential Code, Chapter 1 (section R105.2, exempt work) (https://www.seattle.gov/documents/Departments/SDCI/Codes/SeattleResidentialCode/2021SRCChapter1.pdf, accessed October 4, 2026); SDCI, common projects: house additions and remodels (https://www.seattle.gov/sdci/permits/common-projects/house-additions-and-remodels, accessed October 4, 2026).

We cannot quote a published rule, so we check with SDCI before the job whether a permit applies. None of the SDCI pages read for this site names liners, wood stoves or inserts. What the department does publish: new equipment for heating and venting falls under its mechanical permit, a gas line needs a separate permit, simple jobs can be issued subject to field inspection within 24 hours, and most other applications take about nine weeks.

Three feet at least, and sometimes more. Section R1003.9 of the Seattle Residential Code sets two minimums. Measured from the upper edge of the roof penetration, the top stands no less than 3 feet up. It must also clear, by 2 feet, whatever portion of the building sits within 10 feet of it. The same chapter wants the cap made of stone, metal or concrete, sloped so water runs off, with a drip edge. A spark arrestor, where one is fitted, needs open area of four times the flue outlet.

A damper, outside air and a way to close the opening. Under WAC 51-51-1001 the damper has to be ferrous metal, sits no lower than 8 inches over the upper edge of the fireplace opening, and is worked from the room. Outside air must reach the fire through a duct, 6 square inches at the least, fitted with its own damper. A site-built fireplace also needs one of two things: an induction fan for the flue draft, or doors that close tightly, in metal or glass.

An insert must be listed and labeled to UL 1482, and installed the way its manufacturer directs: that is the 2021 Seattle Mechanical Code. Pellet appliances need an ASTM E1509 listing. For a factory-built fireplace, a Washington amendment printed in the Seattle Residential Code lets no unit go in, whether new or secondhand, without certification and a label under ASTM E2558, the particulate emission test.

Because of what lies under the peninsula, as far as the published studies can tell. After the Nisqually earthquake, Booth, Wells and Givler went block by block over roughly 50 square kilometers, saw about 60,000 chimneys and found 1,556 visibly damaged, clustered in West Seattle more than anywhere else. Neither soft ground, nor slope, nor how far a street lay from the epicenter explained the pattern. The hardest-hit zones coincided with strands of the Seattle fault zone that geologists had already mapped, and the damage faded inside a block or two. A USGS simulation points to a fold in the bedrock that focuses waves arriving from the south.

No, it was the third on record. The USGS authors of the 2001 survey write that unreinforced brick chimneys around Seattle were damaged again and again by the deep earthquakes of 1949, 1965 and 2001, and that West Seattle held localized pockets of heavy damage each time. Their paper notes that chimney damage had been mapped on the peninsula after 1965 as well.

Not an identical rebuild. FEMA's recovery advisory on damaged masonry chimneys says old unreinforced stacks with worn mortar are the likeliest to fall, and that rebuilding one like for like leaves it just as exposed. Its options climb from good to best: cap the chimney at the roof; take the masonry down to the firebox and run a metal flue up from there, with the fireplace kept or an insert added; replace firebox and chimney entirely. The advisory states that this work always needs a building permit.

Where the site falls in Seismic Design Category D0, D1 or D2, yes. There the Seattle Residential Code requires a new or rebuilt masonry chimney up to 40 inches wide to hold four continuous No. 4 vertical bars, with steel straps anchoring it wherever a roof line, ceiling or floor lies higher than 6 feet from grade. Categories A, B and C are exempt. We found no public page giving the category street by street, so that question goes to SDCI.

Yes, for anything that changes the exterior. The city's landmarks program requires a Certificate of Approval from the Landmarks Preservation Board before an exterior alteration to a designated landmark begins, and that holds even when SDCI itself asks for no permit. The same applies to nominated features once a building has been nominated.

Never indoors. Seattle's windstorm analysis records that 49 percent of City Light customers lost power in the December 2006 storm, and that several people in King County died heating their homes with charcoal during the outages. The same document ranks West Seattle among the parts of the city most exposed to wind damage, because it is so heavily forested and falling trees do most of the harm.

Keep the house closed and filter the air inside it. For smoke episodes the Clean Air Agency recommends a HEPA filter, or a box fan fitted with a furnace filter rated MERV-13 or better, one room set aside as a clean room, and shutting the fresh-air intake of an air conditioner. Not every summer brings smoke: the agency's summary for 2024 says the region saw none from wildfires that year.

$99 plus tax, per chimney. That figure does not move with the depth of the visit: a visual check and a camera run down the whole flue are billed alike. A written quote follows, and if you approve it, that $99 plus tax is subtracted from the job total.

It comes off the bill. Once you approve the written quote, the $99 plus tax you paid on the day counts toward that job. If you choose not to go ahead, the fee has covered the visit itself, and the photographs and written findings are yours to keep.

Level 1 visual; Level 2 adds a full camera scan. The technician photographs each finding, and you receive them in writing together with an itemized quote if something needs repair. Both levels are $99 plus tax, and nothing is scheduled until you have accepted the quote.

All 10 of our neighborhoods sit on the peninsula: Alki, Admiral, the Junction, Fauntleroy, Gatewood, Delridge, High Point, Seaview, Arbor Heights and Genesee. Each one has its own page listing the services we carry out there. Book online and the calendar offers the openings for your address; the visit is $99 plus tax wherever you are among the 10.

Book online: the calendar lists the open times for your neighborhood, and picking one holds it. To speak with someone first, call (206) 589-5029. From then on, what concerns your appointment arrives by email and phone.

Sweeping is $189–$449, a cap installed on the chimney is $235–$850, and a new liner is from $1,900. You will find the 12 services priced together on one page. The amount for your chimney is written up after the $99 plus tax visit, and work starts only when you have agreed to it.
