Shoreline, Washington Building Permit Guide

Shoreline sits between Seattle and Snohomish County and publishes its review clocks plainly. The 65, 100 and 170 day periods are the deadlines state law sets for land-use project permit decisions (RCW 36.70B.080), which by definition exclude permits issued for building-code compliance (RCW 36.70B.020); what makes the city’s version useful is that it explains how the clock is counted and when it stops.

Planning and Community Development issues building, tree, clearing and grading and land use permits, with applications submitted through the city’s electronic permitting portal. The city reports annually to the state on permit review timelines for a subset of permit types.

This guide covers work inside the Shoreline city limits. Unincorporated King County is permitted by the county, and Seattle to the south runs its own department and its own codes.

What requires a building permit in Shoreline?

Washington has a mandatory statewide building code. The codes enumerated in chapter 19.27 RCW, the State Building Code Act, are adopted and amended by the State Building Code Council within the Department of Enterprise Services, and they are required in all cities and counties — local government administers and enforces them rather than deciding whether to have them. A city or county may make the state code stricter but cannot opt out of it, and local changes affecting houses or apartments need State Building Code Council approval. So the question in Shoreline is not whether a code applies, but which edition is in force and what Shoreline Planning and Community Development has added to it.

Local amendments, fee schedules and exempt thresholds differ from one jurisdiction to the next, so an exempt list from a neighbouring city is not reliable. An exemption from a building permit is never an exemption from zoning, critical areas review, the energy code or a trade permit. Confirm scope with Shoreline Planning and Community Development before work starts.

Local rules worth knowing

Trees carry a per-tree charge as well as a permit: the city notes a per tree fee for removing significant trees of 24 inches diameter at breast height and greater, referring applicants to the fee schedule for current rates — so on a wooded lot the tree cost scales with the count rather than sitting as a single line

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 programme or Tacoma Power serves the site.

Who handles permitting in Shoreline?

Planning and Community Development issues building, tree removal, clearing and grading and land use permits, publishes annual review timeline performance, and staffs a counter with reduced hours midweek.

Tree permits are triggered three ways rather than one. A permit is required for removal of trees greater than 24 inches diameter at breast height; for removal of trees in the rights of way, which extend beyond the edge of the paved road; and for trees of any size on or near a stream, wetland or steep slope. Removal of significant trees without a permit can result in penalties and code enforcement action.

The submittal standards are strict about file quality. Applications for tree permits must be submitted electronically, all forms and plans must be in portable document format, plans must be printed or plotted to that format rather than scanned from an image, must be plotted to scale with a graphic scale bar, and must be flattened and unlocked to allow mark-up, with a blank space left for the city’s stamp. Incomplete submittals and documents not meeting those standards will not be accepted for review.

In 2025, building permits issued in Shoreline authorized 26 new privately owned housing units, 15 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Residential work — new homes, interior remodels, additions and demolitions — runs through the same portal as tree work. Some projects qualify for a permit exemption and can begin without a permit, but the city is explicit that exemptions do not apply to properties with environmentally sensitive or critical areas including steep slopes, wetlands, streams, beaches and lakes.

How Washington contractor credentials work

Commercial permits

Clearing and grading permits cover work meeting the municipal code thresholds, such as grading in or near critical areas, changing the existing grade by 4 feet or more, or replacing impervious surfaces above a defined size. Where trees are being removed without any grading, the tree removal permit is the correct application unless six or more trees are involved.

Registrations, trade certifications and design professionals

Three credential layers appear on Washington projects: the state contractor registration under chapter 18.27 RCW, which nearly everyone doing the work needs; separate state trade certification for electricians and plumbers, each examined and administered by its own programme; and, on commercial and larger residential work, drawings stamped by a Washington-licensed architect or professional engineer. Confirm what Shoreline Planning and Community Development requires for the specific building before filing.

Most Washington contractors register with the Department of Labor and Industries (with a surety bond and insurance) rather than holding a licence; electrical and plumbing contractors also need an L&I contractor licence. Contractor licensing in Washington

Shoreline permit costs and fees

Shoreline fees follow the published schedule, with a per tree fee for removing significant trees of 24 inches diameter and greater charged in addition to the permit fee itself.

Washington sets the code statewide but leaves the fee schedule local, so two jurisdictions on the same edition can price the same project very differently. The electrical fee is the one that most often surprises people, because it is paid to L&I rather than with the building permit. Ask Shoreline Planning and Community Development for the schedule in force on your filing date, and confirm the electrical route separately.

Fees are set locally, plus a small state permit fee (RCW 19.27.085); the electrical fee goes to whichever body issues the electrical permit. Permit fees in Washington

Trade permits and who may pull them

Plumbing and mechanical permits are local; electrical permits come from the Department of Labor and Industries unless the city runs its own electrical programme or Tacoma Power serves the site. Trade permits in Washington

How to apply for a Shoreline building permit

Review, corrections and what actually causes delay

In Washington the first cause of delay is the energy code, because the state code is its own instrument and more demanding than the international one most designers default to. After that comes critical areas review, which reaches ordinary residential work near wetlands, streams, steep slopes and shorelines and adds its own study and mitigation timeline. Then the electrical split, where a project waits on a local inspection that was never going to happen because the electrical permit sits with L&I. Then edition confusion around the switch-over date, when a new state edition takes effect and local amendments change with it. Build review time into the schedule and confirm the checklist with Shoreline Planning and Community Development before filing.

The state code sets a 180-day default for permit validity, but Shoreline may change it, so confirm the expiry on phased or delayed work. Permit validity in Washington

Inspections in Shoreline

Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in plumbing and mechanical, insulation and energy code compliance, fire systems on commercial work, and final, with a certificate of occupancy before the building is used. Incomplete submittals and documents not meeting the published file standards will not be accepted for review at all, so a formatting failure costs the whole intake rather than a correction cycle.

The point to plan around is that the electrical inspections may be booked with a different body entirely. Because L&I holds the electrical permit here, its inspector attends on the state’s schedule and the local inspector will not sign off electrical work. Sequencing a cover-up around two independent inspection queues is the practical skill on a Washington job.

Do not cover work before the required inspection has been approved. Keep the issued permits — plural — the approved plans and the energy code documentation available on site.

Shoreline permit search and official resources

Permit records in Washington are split the same way the permits are. Where Shoreline Planning and Community Development is the authority for the City of Shoreline, it holds the building, plumbing and mechanical records — while the electrical record sits with the state Department of Labor and Industries (L&I), which issues the electrical permits and carries out the electrical inspections here. If you are buying, refinancing or renovating, check both, because a clean local record does not mean the electrical work was ever permitted.

Frequently asked questions

How long will my permit take?

The city publishes 65 calendar days for administrative decisions including building permits and tree removals, 100 for administrative decisions requiring public notice, and 170 for decisions requiring a public hearing. The clock starts after the application is determined complete and includes only those days the city is reviewing.

What stops the clock?

You do, in effect. The clock pauses when additional information or corrections to plans are requested, and resumes once the requested information is provided to the city. Turning corrections around quickly is the single biggest thing within your control.

When do I need a tree permit?

Three triggers. Removal of trees greater than 24 inches diameter at breast height; removal of trees in the rights of way, which extend beyond the edge of the paved road; and trees of any size on or near a stream, wetland or steep slope.

Is there a charge per tree?

Yes. The city notes a per tree fee for removing significant trees of 24 inches diameter at breast height and greater, with rates in the published fee schedule.

Does my exemption still apply near a stream?

No. The city states that exemptions do not apply to properties with environmentally sensitive or critical areas, which include steep slopes, wetlands, streams, beaches and lakes. Contractor credentials are unaffected either way, and they are a state matter. Most Washington contractors register rather than hold a licence; electrical and plumbing contractors must also hold an L&I contractor licence. Under chapter 18.27 RCW a contractor registers with the Department of Labor and Industries, files a continuous surety bond of $30,000 as a general contractor or $15,000 as a specialty contractor, and keeps liability insurance on file, renewing every two years. Registration is not a competence test and does not authorise trade work: electrical certification comes under chapter 19.28 RCW and plumbing under chapter 18.106 RCW. The electrical permit comes from the state, because the Electrical Program at the Department of Labor and Industries (L&I) issues electrical permits and carries out electrical inspections here under chapter 296-46B WAC.

Which code edition applies?

The state edition as amended by the city. Washington has a mandatory statewide building code. The codes enumerated in chapter 19.27 RCW, the State Building Code Act, are adopted and amended by the State Building Code Council within the Department of Enterprise Services and are required in all cities and counties, so local government administers and enforces them rather than choosing whether to have them. The 2021 editions took effect on the fifteenth of March, 2024 after two delays, and the 2024 editions are dated to take effect on the third of May, 2027. The state adopts a new edition every three years and reviews the codes in two groups, but all of them take effect on the same date (the 2021 codes on 15 March 2024, the 2024 codes on 3 May 2027). A city or county may make the state code stricter but cannot opt out of it; local changes affecting houses or apartments need State Building Code Council approval, and the residential energy code cannot be changed locally.
