("hunting cabins", "seasonal cabins" ,etc.), regardless of the building's size or how often the building is occupied.
Please contact our office or review the "Tiny House" page
on the Washington State Department of Labor & Industries (L&I) website to assist you in determining whether or not you need a Land Services issued building permit for a "tiny house".
Any structure that will have plumbing, habitable space (living, sleeping, eating or cooking) and/or be for commercial/public use requires a building permit and associated land use approvals from the Planning Division.
A residential utility structure that is over 200 square feet and/or is on a permanent foundation and does not contain plumbing or habitable space (living, sleeping, eating or cooking) may not require a building permit if it is located 20 feet or more from any property line or other structure that contains habitable space. Before building permit requirements may be determined, the Site Analysis process must be completed through the Planning Division. This site-specific process will reveal whether or not there is an underlying "plat restriction" that requires building permits for all structures. If such a restriction exists, a building permit will be required for the structure.
Residential utility structures that are 200 square feet or less, do not contain plumbing, do not contain habitable space (living, sleeping, eating or cooking) AND are not on a permanent foundation (no posts in the ground, traditional footings, etc.) do not require land use approval from the Planning Division or a building permit.
***please see the IBC and IRC for other permit exemptions***
BUILDING PERMITS AND BUILDING PERMIT APPLICATIONS ARE
CONSIDERED ABANDONED (EXPIRED) AFTER 180 DAYS (6 MONTHS) OF INACTIVITY WITH OUR
OFFICE. Please contact our office within any 180-day period
between inspections to schedule the next required inspection or to provide our

Construction plan reviews are currently taking
approximately 3-4 weeks. If the Planning Division land use approval/s are
complete and we have all other required building permit application material,
the building permit should be issued within a few days of the construction plan
review being complete. This time frame varies depending upon how busy we
are. Typically, March through September is our busiest time of year.
A building permit is your authorization to begin construction and schedule required on-site construction inspections.
An inspection record is a record of each on-site construction inspection as recorded by the building inspector/s who performed the inspection.
A certificate of occupancy is issued after all of the required construction inspections, including the final inspection, have been approved by the building inspector/s, as noted on the inspection record. This document certifies that a building is in compliance with all applicable codes, requirements and regulations and is suitable for occupancy.
Although the terms mobile home, manufactured home and modular home are often used interchangeably, they classify three distinctly different types of homes (see definitions below). Each of these types of homes requires permitting through our office. We issue building placement permits for mobile and manufactured homes, and standard residential building permits for modular homes. Modifications made to mobile and manufactured homes are permitted through Washington State Department of Labor and Industries (L&I).
A mobile home is a factory built, single family dwelling unit built prior to June 15, 1976, to standards in place prior to HUD Code.
A manufactured home is a factory built, single family dwelling unit built to conform to the Manufactured Home Construction Safety Standards (HUD Code) (Department of Housing and Urban Development). Of the three types of factory built homes, our office most commonly sees permit applications for manufactured homes.
A factory built, single family dwelling unit built to conform to all state, local and/or regional codes that apply based on the final location of the home, just like site-built homes
