Zoning Codes
Recent code changes for zoning aren't reflected in Official Codes until about six months after adoption. Please check Recent Code Changes to see new ordinances.
Use the information below to find out which zoning your property is in and which codes apply. Zoning determines what you can build on or do with a property, the setbacks (also called "yard" requirements in code), lot sizes and more.
- To Check Zoning (three steps)
- Open the property information report for a property. (you'll need address or parcel #).
- Look for Jurisdiction of Influence (part of zoning despite the name).
- Most county-permitted properties show "Same as Permitting Jurisdiction" or "OLYUGA," or "TUMUGA" or "LACUGA."
- If there is any other UGA listed, use "Same as Permitting Jurisdiction."
- UGA stands for Urban Growth Area. Which is an area in unincorporated Thurston County.
- For:
- SAME AS COUNTY go to Thurston County Code Title 20: Zoning
- LACUGA go to Thurston County Code Title 21: Lacey Urban Growth Area
- TUMUGA go to Thurston County Code Title 22: Tumwater Urban Growth Area
- OLYUGA go to Thurston County Code Title 23: Olympia Urban Growth Area
- Next look for Zoning which can be letters, numbers or words or a combination of any of those (Example: RRR 1/5, Rural Residential/Resource).
- Zoning definitions
- Jurisdiction of Influence - determines which zoning code applies.
- UGA is Urban Growth Area -an area that will become part of Olympia, Tumwater or Lacey at some time in the future. Regulations in those areas typically match the city regulations.
- Legal lot - a parcel of land developed through laws in effect at the time of the original subdivision. The criteria to determine the legal status of a lot is specified in section 18.04.045 of Title18 of the Thurston County Code.
- Tax lot / Tax parcel- a parcel which appears on the Thurston County Assessor's map and has been assigned a tax parcel number by the Assessor. Tax parcel numbers are assigned for billing purposes.
