First, it is the law, and work done without a permit may have to be redone or removed at the property owners cost. Additionally, getting a permit ensures that the project has met the minimum standards of safety; it makes selling the property easier because lenders may not finance a home sale if illegal work was done; and in the case of an insurance claim, illegal work may not be covered if it is damaged.
A permit is required from the City for the following activities.
A building permit is not required for the following work:
Start by filling out a permit application. Permit applications are available at the Permit Center counter on the main floor of City Hall. You can fill out the application at City Hall or you may take the application with you to fill out later. Applications also may be mailed, faxed or emailed to you upon request. Applications are also available via Permit Forms in our Document Center.
Information you need to provide on the application includes your name, address, telephone number, description and valuation of the work being done. If you need help filling out the application, a staff member will be happy to assist you.
To start the review process, you need to submit a completed application and plans, and a submittal fee. You may submit the permit application in person or by mail.
Once a permit is ready, you will be called at the number provided on the application. You then pay for the permit at that time and take it with you, along with the approved plans and the inspection card that details what inspections are required.
Current turnaround times for construction permits are as follows.
Land use permits generally take 120 days to process, between when a completeness letter is sent and when a decision is issued.

To get a permit cost estimate for any project, call the Permit Center at 425-489-2754.
Valuation should reflect the cost of the project including all work covered by the permit. The valuation should also include labor, even if you are doing the work yourself. Valuations are frequently compared to available cost estimators and will be adjusted if the valuation provided appears to be in error.
The plans submitted with the permit must be neatly drawn and drawn to a usable scale. One-quarter inch to one foot is a common scale for building plans. Typical residential plans would include a site plan, floor plan, cross section, elevation, details of various structural components and a window schedule.
Plans should be dimensioned and include information on use of rooms, wall and ceiling finishes, lumber sizes, and spacing.
Standard requirements for site, building, and civil plans are available in the Permit Forms folder.
Washington State has requirements for when an architect is required to complete a set of plans. Generally, any building over 4,000 square feet, where the life safety or structural systems are modified, must be designed by a licensed architect.
A structural engineer is required to prepare building plans when the design does not use the prescriptive building code requirements, or for walls or rockeries that require a building permit. A civil engineer is required to design drainage and roadway improvements.
A property owner is allowed to do work on their own property, for single-family and commercial properties. If you hire someone to do the work for you, they must be a contractor licensed with the state of Washington. You can look up contractors on the Department of Labor and Industries website. You can also review the laws on hiring a contractor at this same website.
All work is subject to inspection by the City. The number and type of inspections vary depending on the work being done. When the permit is issued, you will receive a blue inspection record that lists the inspections required. The website and telephone number to call for scheduling an inspection will be on the blue card.
It is the owner or contractors' responsibility to call for an inspection when the work is ready. When you call, you will need to know the following information: the permit number, the project name, the site address, the name and phone number for the contact person, the date and time of the inspection, and the kind of inspection you are requesting.
You may schedule your inspection online before 6 am the day of using our Permit Portal.
Inspections requests over the phone can be made up to 3 pm the previous business day. To reach the voicemail inspection line call 425-489-2754. Press 1 for inspections.
If you have any questions concerning your project or inspections, you may call the inspector directly at 206-276-6856.
