Marysville, Washington Building Permit Guide

Marysville sits north of Everett in Snohomish County and has grown quickly. It is also the counter-example to most of this band: where nearly every Washington city sends electrical work to the state, Marysville added electrical permit processing to its own building services.

All building permit applications are submitted through the city’s permit portal, and since January 2025 all land use applications must go through the same portal. Building Services reviews and inspects for compliance with city code, the international building codes, the plumbing and mechanical codes and its own electrical permit processing.

This guide covers work inside the Marysville city limits. Snohomish County permits unincorporated areas separately, and the neighbouring Snohomish County cities administer the state code themselves.

What requires a building permit in Marysville?

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 Marysville is not whether a code applies, but which edition is in force and what Marysville Building Services 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 Marysville Building Services before work starts.

Local rules worth knowing

Refunds are possible but tightly bounded: the building official may authorise refunding not more than 70 per cent of the plan review or permit fee paid where no review or work has been done, and no refund may be authorised except on written application filed by the original permittee not later than 90 days after the date of the fee payment

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 Marysville?

Building Services reviews and inspects plans and structures throughout the city for compliance with city code, the international building codes, the plumbing and mechanical codes and its own electrical permit processing, with permitting staff also handling business licences, plan submittals and public information requests.

The development review sequence has one fixed rule inside an otherwise flexible process. Concurrent review of the planning and land use review and the civil plan review is feasible, but the city requires the project to go through at least one round of land use review before the formal civil plan review can begin — the reasoning being that major revisions should be resolved before detailed engineering design review starts.

Site construction has its own entry point. After civil plan review is complete and the city has issued construction plan approval, site construction can commence — internal roadways, utilities, street frontage improvements, stormwater facilities, building site preparation and approved model homes. To break ground the applicant must apply for and coordinate an on-site pre-construction meeting covering the approved civil plans and how construction inspection will operate.

In 2025, building permits issued in Marysville authorized 700 new privately owned housing units, 294 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Small residential projects — mechanical, plumbing, electrical and re-roofs — can be applied for quickly through the portal. One storey detached accessory structures used as tool and storage sheds, playhouses and similar uses are exempt where the net floor area does not exceed 120 square feet. Inspections require an adult of at least 18 to provide access.

How Washington contractor credentials work

Commercial permits

Larger residential and commercial projects upload materials through the portal and then notify the city, after which staff provide an upload link and a unique file number. The building and fire departments review the building permit application concurrently, and civil engineering approvals cover stormwater, grading, water, sanitary sewer and right-of-way with a separate grading permit applied for alongside the civil construction submittal.

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 Marysville Building Services 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

Marysville permit costs and fees

Marysville publishes permit fees and land use fees separately, with civil construction plan review charged on a base fee plus an hourly review rate. Refunds are limited to 70 per cent of the plan review or permit fee and only where no review or work has been done.

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 a separate city permit with its own fee. Ask Marysville Building Services 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 Marysville 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 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 Marysville Building Services before filing.

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

Inspections in Marysville

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. An inspector needs an adult of at least 18 years old to provide access, so unattended sites cannot be inspected.

The city issues its own electrical permits, so electrical inspections are requested from the city rather than from the state.

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.

Marysville permit search and official resources

Permit records in Washington are split the same way the permits are. Where Marysville Building Services is the authority for the City of Marysville, it holds the building, plumbing and mechanical records — and the electrical record too, because the city issues its own electrical permits and carries out its own electrical inspections. 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

Who issues my electrical permit in Marysville?

The city does. Marysville describes electrical permit processing as part of its own Building Services alongside building, plumbing and mechanical work, which places it in the minority of Washington jurisdictions where electrical does not go to the state programme. Confirm the route for your specific scope. 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 city, which runs its own electrical permits and inspections; elsewhere in Washington the Electrical Program at the Department of Labor and Industries (L&I) usually issues them.

Can land use and civil review run at the same time?

Partly. Concurrent review of the planning and land use review and the civil plan review is feasible, but the city requires the project to go through at least one round of land use review before the formal civil plan review can begin, so that major revisions are resolved before detailed engineering review starts.

Can I get a refund if the project does not proceed?

Only within limits. The building official may authorise refunding not more than 70 per cent of the plan review or permit fee paid where no review or work has been done, and only on written application by the original permittee filed no later than 90 days after the date of the fee payment.

Do I need a permit for a small shed?

One storey detached accessory structures used as tool and storage sheds, playhouses and similar uses are exempt where the net floor area does not exceed 120 square feet. Zoning and setback rules still apply.

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.

What do I need in place for an inspection?

Access, and a person to provide it. An inspector needs an adult of at least 18 years old to provide access in order to perform the inspection, so an unattended site cannot be inspected.
