Summary

In unincorporated Washington County's Transit Oriented Districts, a veterinary office without outdoor kennels needs a discretionary Type II land use permit and is only allowed in the commercial, business and employment districts, not in any of the transit-oriented residential districts.

City-specific rules exist: Hillsboro has its own veterinary clinic zoning rules that differ from Washington County's county-level regulations. If you live in Hillsboro, check the city-specific page instead.

Full Breakdown

Section 375-10, Table A of the Community Development Code sets the permitted and prohibited use table for the county's Transit Oriented Districts: TO:RC (Regional Center), TO:BUS, TO:EMP, and the residential tiers TO:R9-12, TO:R12-18, TO:R18-24, TO:R24-40, TO:R40-80 and TO:R80-120. Under the 'Office Uses' heading, the table lists 'Veterinary Offices Without Outdoor Kennels' as a Type II use in TO:RC, TO:BUS and TO:EMP, and marks it 'N,' not permitted, in every one of the six residential TO districts. That places veterinary offices in the same procedural track as professional offices, medical offices and clinics, financial and insurance offices and administrative offices in this table, all Type II in the three commercial/employment districts and barred from the residential tiers.

Kennels themselves are treated far more restrictively: the same table lists 'Kennels' as not permitted ('N') in any Transit Oriented District, so an outdoor kennel use is not an option here even where a veterinary office is allowed. 2 may appeal the decision under Section 209. Section 375-10 further ties development standards for the Transit Oriented Districts back to Article IV, including the Significant Natural Resources standards of Section 422, so a veterinary office proposal in a TO district must also clear those generally applicable standards, and Section 375-9 and 375-8 supply the applicable density and dimensional tables that govern the site plan for the underlying use.

Violations & Fines

Operating or building a veterinary office in a Transit Oriented District without an approved Type II permit, or operating outdoor kennel facilities anywhere in a TO district, exposes the operator to the county's code enforcement process, including a stop-use order and denial of occupancy or business licensing until the required Type II review is completed.

Frequently Asked Questions

Can I open a veterinary clinic in a TO residential district in unincorporated Washington County?
No. Section 375-10, Table A marks 'Veterinary Offices Without Outdoor Kennels' as 'N,' not permitted, in all six Transit Oriented residential districts, TO:R9-12 through TO:R80-120. It is only listed as an allowed Type II use in the TO:RC, TO:BUS and TO:EMP districts.
What review does a Type II veterinary office permit involve?
Section 202-2.3 requires the Director to mail notice under Section 204 and hold a 14 calendar day written comment period before deciding. It is not a hearing-based Type III review, but any party of record under Section 205-3.2 can appeal the Director's decision under Section 209.
Can a vet clinic in this county keep an outdoor kennel?
Not in a Transit Oriented District. Section 375-10, Table A lists 'Kennels' as not permitted ('N') across every TO district column, separate from the 'Veterinary Offices Without Outdoor Kennels' line, so outdoor kennel operations are barred regardless of the veterinary office's Type II approval.
