Full Breakdown
UDO § 23.08.220(c) creates a distinct short-term rental category, the 'Transient Residence, aka "Short-term rental,"' covering any rental of a single-family home for less than thirty days. Because the subsection classifies these rentals as commercial uses, § 23.08.220(c)(1) requires them to carry a fire sprinkler system throughout that meets the WA State Building Code. Operators must also comply with the county's short-term rental licensing chapter, GCC Chapter 15.03, referenced in § 23.08.220(c)(2), pay applicable lodging taxes under RCW 64.37.020 per § 23.08.220(c)(3), and meet the state's consumer safety requirements in RCW 64.37.030 per § 23.08.220(c)(4).
The insurance mandate sits right after those: § 23.08.220(c)(5) requires the rental to hold and maintain liability insurance coverage as required by RCW 64.37.050, folding the state's short-term rental insurance floor directly into county zoning code so Grant County Development Services, not just a state agency, can treat a missing policy as a local code violation. The same subsection layers on operational standards beyond insurance, including a disturbance standard in § 23.08.220(c)(6), an added ADA-accessible parking space in § 23.08.220(c)(7), and a ban on outdoor advertising signs in § 23.08.220(c)(8), so an operator has to satisfy the whole list, not just the insurance line, to stay in compliance.
Violations & Fines
Grant County Development Services enforces § 23.08.220(c) under GCC § 1.32.020, and an operator who cannot produce proof of the RCW 64.37.050 liability coverage on request faces a $500 fine per occurrence under GCC § 1.32.140. Because a short-term rental is licensed locally under GCC Chapter 15.03, missing insurance can also support suspension or revocation of that license under §§ 1.32.240 and 1.32.250 until coverage is restored.
