Lynnwood, Washington Building Permit Guide

Inside Lynnwood city limits, Development and Business Services (DBS) reviews and issues building permits and also runs the City’s own electrical permits and inspections, so no Labor and Industries electrical permit is needed. Applications are filed, paid for and tracked in the Online Permit Center. The City’s 2026 fee table prices a building permit by valuation and adds plan review at 65% of that fee and a 2.5% technology fee; a first review of a house or addition is estimated at 4 to 8 weeks.

The DBS Permit Center is at Lynnwood City Hall, 19100 44th Avenue West, open Monday to Friday from 8:30 a.m. to 4 p.m., on 425-670-5400 and at Permits@LynnwoodWA.gov. The City warns that scammers have posed as DBS staff and asked for wire transfers; if an urgent payment request comes from an address that is not the City’s, call the Permit Center. Lynnwood had 42,132 residents in the Census estimate for 2025.

Many homes with a Lynnwood mailing address are outside the city, and DBS does not permit unincorporated land; check the City’s boundary map first, because those addresses are Snohomish County’s.

What requires a building permit in Lynnwood?

Lynnwood adopts the state’s residential and building codes without a local exemption list of its own, so the exemptions are those of the 2021 International Residential Code, section R105.2. A typical remodel, the City says, needs a building permit for structural work, an electrical permit if wiring is touched, a plumbing permit if sinks or pipes move and a mechanical permit if the heating or ventilation changes.

What the city decides and what the state holds

Washington supplies the codes and their exemptions. Lynnwood writes its own fee chapter (LMC 3.104), the permit portal and submittal standards, zoning in its development code, critical areas review, its utility and right-of-way rules and a full electrical program that L&I lists among the city programs that replace the state’s.

Washington has a mandatory statewide building code under chapter 19.27 RCW that every city and county enforces and may make stricter; electrical permits come from the Department of Labor and Industries unless the city runs its own program or Tacoma Power serves the site.

Lynnwood building department: who handles permitting

DBS brings building, electrical, planning, development engineering and fire review into one Permit Center. It handles residential and commercial building permits, electrical permits, boundary line adjustments, subdivisions, driveway aprons into the right-of-way and clearing and grading permits. Fire alarm and sprinkler permits are priced in the fire chapter of the same fee code.

Permit types

Residential permits

The City publishes separate checklists for a residential building permit, an interior remodel, an accessory structure, a re-roof, a swimming pool or spa, a demolition, a manufactured home and the electrical, plumbing and mechanical permits, plus an energy code form for new homes and for remodels. It also posts sample drawings for decks, garage conversions, home additions and adult family home conversions, and an ADU guide. Plans and documents must follow the City’s electronic submittal standards. A house’s plumbing and mechanical permits for new construction are each 10% of the building permit fee; in a remodel or addition, each is $257 for up to four fixtures or pieces of equipment and $22 for each one after that.

Commercial permits

Commercial and multifamily buildings, tenant improvements, commercial kitchen hoods, signs and adult family homes each have their own checklist, and tenants moving in after an improvement follow the City’s occupancy and stocking approval sheets. A new commercial or multifamily building is estimated at 6 to 12 weeks for the first review and a tenant improvement at 4 to 8 weeks. Commercial plumbing and mechanical plan review is 40% of those permit fees, and fire review of a building permit adds 25% of the building permit fee.

For tenant improvements and new commercial builds, Alliance handles commercial permit filing through issuance. More on this: commercial building permits explained.

What comes before the building permit

Land use approval sometimes has to come first: design review, conditional use permits, variances and plats are estimated at 7 weeks. Sites with wetlands, streams or steep slopes use the City’s critical areas checklist, and larger projects the SEPA environmental checklist. Any work outside the building footprint, including grading, water, sewer, storm drainage, tree removal and work in the public right-of-way, goes to Development Engineering, whose civil plan review is estimated at 8 to 10 weeks. The City also posts a water and sewer service area map.

Lynnwood permit costs and fees

Permit fees are written into the Lynnwood Municipal Code, chapter 3.104, which the City calls its fee schedule. The tables in force carry a “2026 Fee” column set by Ordinance 3502 of 2025, and the fire table was amended again by Ordinance 3508, adopted May 11, 2026. Building fees use the ICC valuation table or the building code’s square footage method, whichever gives the greater value. The City’s fee chapter does not print the State Building Code Council fee that state law adds to building permits.

Worked example. A $60,000 house remodel falls in the $50,001 to $100,000 band: $1,181.86 plus 10 × $12.62 ($126.20) is a building permit fee of $1,308.06. Plan review at 65% adds $850.24, and the 2.5% technology fee on those two amounts adds $53.96, for $2,212.26 before the state building code fee and any electrical, plumbing or mechanical permit.

New homes also pay impact fees before the permit is issued. The park impact fee schedule for January 1, 2026 to December 31, 2027 sets $6,969.54 for a single-family house and $3.54 per sq ft for commercial space, plus a $300 administrative fee; transportation impact fees depend on the land use and the traffic zone on the City’s map.

Trade permits and who may pull them

All three trade permits are Lynnwood’s. Electrical permits are bought from DBS and priced from the City’s own electrical table: adding or altering up to 10 circuits in a house with no service change is $147 plus $15 for each further circuit, up to $200 in total, and a service or panel change starts at $147. Plumbing, gas piping, backflow and mechanical permits are issued on the same portal. The City also publishes a list of electrical work that needs no permit.

How to apply for a Lynnwood building permit

Review, corrections and what causes delay

The City’s review times sheet adds 1 to 2 weeks of Permit Center processing before plan review starts. First reviews are estimated at 4 to 8 weeks for a new house, addition or alteration, 2 weeks for commercial trade permits and signs, and 1 week for a small fire alarm or sprinkler change; each later round is estimated at 2 to 4 weeks. Each resubmittal needs a comment response letter, and review of changes to approved plans is billed at $228 an hour.

Inspections in Lynnwood

Inspections are requested only in the Online Permit Center, after the permit is issued, from “My Inspections” on the dashboard; the account must match the owner or applicant named on the permit. Requests are due by 4 p.m. the day before, with a jobsite phone number. An inspection not reached that day carries over to the next workday, and the approved plans and permit card must be on site. A house typically moves through footing and setback, foundation, groundwork, under-floor, shear wall, exterior insulation, a combined frame and plumbing inspection, gas test, interior insulation and final.

The City’s inspection handout says a permit expires unless an inspection is requested, or an extension asked for, within 180 days of issuance, that each inspection adds another 180 days, and that no building permit runs past two years from issue. In a flood fringe an elevation certificate is due before the final building inspection. Every other permit on the project, such as fire sprinklers and site development, must be final first, and a home may not be lived in until it passes its final inspection or receives a certificate of occupancy.

Lynnwood permit search and official resources

Anyone can look up permits without an account: the Online Permit Center’s public portal searches by address, owner name, parcel number or map and shows each parcel’s permit applications and zoning. Permits applied for before January 10, 2024 are not in that portal, so ask the Permit Center, or file a public records request for older plans. Lynnwood takes part in the National Flood Insurance Program, and FEMA’s status book lists June 19, 2020 as the date of its current map.
