Key Zoning Facts
Kent Zoning Overview
Kent is a major city in Washington with approximately 136,588 residents, located in King County. The city manages land use and development through its zoning code, administered by Planning Services. Kent's zoning divides the municipality into districts regulating permitted uses, building heights, lot sizes, setbacks, and density.
Kent 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
Kent's zoning code includes several residential districts. The SR-1 district requires a minimum lot size of 1 acre for very low-density development. The SR-4.5 district requires approximately 9,600 square foot lots, and the SR-6 district requires 7,200 square foot lots. The MR-D district permits duplexes and attached housing. All residential districts have a 35-foot height limit.
Commercial activity is served by the CC (Community Commercial), DC (Downtown Commercial), and GC (General Commercial) districts. Industrial uses are provided for in the M1 (Industrial Park) and M2 (General Industrial) districts.
ADU (Accessory Dwelling Unit) Rules
Kent 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 applies to cities planning under the Growth Management Act (which includes most urban Washington cities). Contact Kent Planning Services for current requirements including size limits, setbacks, and permitting procedures.
Development Process
Development in Kent generally requires obtaining the appropriate permits. The process typically involves:
- Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
- Site Plan Review — For commercial and multi-family projects, submit a site plan for review
- Building Permit — Apply for a building permit with construction documents
- Inspections — Schedule required inspections during construction
- 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 Kent, 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 Planning Services at (253) 856-5454 for pre-application guidance

State law (statewide context, not city-specific):
Washington HB 1337 (2023, effective July 23, 2023) requires cities and counties planning under the Growth Management Act to allow at least two accessory dwelling units per lot in zones that permit single-family homes within urban growth areas. The law limits impact fees on ADUs, prohibits owner-occupancy requirements, and requires that ADUs of at least 1,000 sq ft be allowed. HB 1110 (2023) separately legalized middle housing (duplexes through sixplexes depending on city size).
