Local rules
Which pet businesses need a permit around Puget Sound
A dog walker and a boarding kennel face different rules. Knowing which is which tells you what paperwork to ask for.
King County, including Seattle
Public Health – Seattle & King County regulates pet businesses such as pet shops, daycares, grooming facilities and mobile groomers. (King County Pet Business Program)
Its permit page lists these as exempt from a Public Health permit:
- dog walkers;
- trainers who do not board animals;
- boarding three or fewer dogs or cats;
- pet care provided in the client's home.
New pet businesses submit plans before they build or remodel, and need zoning sign-off from their city; in Seattle that comes from SDCI. (King County)
Unincorporated Pierce County
Boarding dogs or cats for private owners, for all or part of a day, needs a Boarding Kennel or Cattery license from the County Auditor. The license costs $200 and expires on December 31. Anyone keeping more than ten dogs or cats must provide kennel facilities, and first-time applicants need a development permit. (Pierce County)
Cities inside Pierce County, Tacoma included, set their own rules. Ask the operator which license they hold and from whom.
What to ask a daycare or boarding operator
- Which permit or license do you hold, and who issued it?
- How many dogs are here at once, and how many staff?
- Which vaccines do you require from other dogs?
- Where do dogs sleep, and is someone on site overnight?
- What happens if my dog is injured: which vet, and who pays?
In-home sitters and walkers
Because King County exempts in-home care and walking from its permit, the checks fall to you: a meet-and-greet, references, an insurance certificate, and a Washington business license once the walker grosses $12,000 a year. (DOR) Start with how to hire a dog walker or pet sitter.
