Building Permitting Services

Welcome! Permits are important to ensure your project is safe and follows city code. Additionally, obtaining a permit will save you money in the long run, and will also protect your property value, improve public health, safety, and welfare, and makes property easier to sell. 

What information do I need to provide upon submittal?

Every permit and project is different. Our permit applications include a checklist of required submittal documents. With your completed application, submit all documents listed on the checklist that are applicable to your project. 

We are happy to assist you. If you are wondering if you need a permit, you can reference the exemptions from the permits section of the Sequim Municipal Code. 

What type of permit do I need?

We have over the counter permits for smaller projects such as residential heat pump install/replacement, re-roofs, solar installation, and small-scale plumbing projects. Note: for commercial mechanical and plumbing projects please use our residential/commercial building permit application.

For tenant improvements, remodels, or additions please use our residential/commercial building permit application and provide the valuation of your project.

For new construction, please use our residential/commercial building permit application.

For manufactured homes, please use our manufactured home permit application and provide the valuation of your project.

If you have any questions along the way, please contact us! We are happy to assist you.

Once the proper permit is applied for and the fees are paid, the review time is currently about six to eight weeks.
