Kirkland Zoning Overview

Kirkland is a city in Washington with approximately 92,175 residents, located in King County on the eastern shore of Lake Washington. The city manages land use and development through its zoning code, administered by the Planning & Building Department. Kirkland's zoning divides the municipality into districts regulating permitted uses, building heights, lot sizes, setbacks, and density.

Kirkland follows the Washington State Building Code (WAC 51-50/51), which is based on the International Building Code (IBC) and International Residential Code (IRC).

Primary Zoning Districts

Kirkland's zoning code includes several residential districts. The RSA-2 district requires a minimum lot size of 12,500 square feet with a 30-foot height limit. The RS-7.2 district allows 7,200 square foot lots. The RM-5.0 district accommodates multifamily housing with 5,000 square foot minimum lots.

Commercial activity is served by the BN (Business Neighborhood) and BC (Business Community) districts. The LI (Light Industrial) district provides for warehousing and light manufacturing.

ADU (Accessory Dwelling Unit) Rules

Kirkland allows ADUs (Accessory Dwelling Units). Under Washington state law HB 1337 (2023), cities are required to allow ADUs, with up to 2 ADUs permitted per lot in most areas. This is a state mandate that applies to all Washington cities. Contact the Planning & Building Department for current requirements including size limits, setbacks, and permitting procedures.

Development Process

Development in Kirkland generally requires obtaining the appropriate permits. The process typically involves:

  1. Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
  2. Site Plan Review — For commercial and multi-family projects, submit a site plan for review
  3. Building Permit — Apply for a building permit with construction documents
  4. Inspections — Schedule required inspections during construction
  5. Certificate of Occupancy — Obtain final approval before occupying the structure

For projects that do not conform to existing zoning, property owners may need to seek a variance, special exception, or rezoning.

Key Considerations

Before starting any development project in Kirkland, property owners should:

  • Verify the zoning classification of their property
  • Review setback, height, and lot coverage requirements for their specific district
  • Check for any overlay districts or special regulations
  • Determine if the property is in a flood zone using FEMA's flood map service
  • Confirm whether HOA covenants or deed restrictions apply
  • Contact the Planning & Building Department at (425) 587-3600 for pre-application guidance
