Property Development Questions

General guidance pertaining to the development of an existing property.

Verify the property is within Duvall city limits
- Enter the address or parcel number on King County parcel viewer, click on Assessor’s Report > Property Detail and verify the Jurisdiction is Duvall. Contact King County permits if the Jurisdiction is King County.
Determine what is allowed within the zoning designation
- Use the current zoning map to determine what is allowed for your zone: permitted uses, accessory uses, conditional uses. If a use is not listed in most cases it is prohibited.
Review development standards in Duvall Municipal Code (DMC)
- Review lot area and site requirements like setbacks, density, impervious coverage, and building height.
- Review additional development standards (DMC Chapter 14.64), design guidelines (DMC Chapter 14.34), landscaping standards (DMC Chapter 14.38).
Refer to City of Duvall sensitive areas maps to locate potential environmentally critical areas
- Review sensitive area regulations (DMC Chapter 14.42).
Review our permit processing ordinance (DMC Chapter 14.08) and identify your type of project permit to get familiar with process requirements.
- Permit types III and IV require a pre-application meeting.

Review and fill out applications and permit intake checklists from our permitting portal.
Other applications are also available on the Land Use Applications page.

Email planning@duvallwa.gov and include address or parcel number of the property.

In general, the city does not have feasibility studies for vacant properties.
