Executive Summary

• Are STRs allowed in Shelton, WA? Yes. Mason County has not adopted any city- or county‑specific STR regulations as of the latest county communications (the review is “on hold”). Washington State’s STR statute—RCW 64.37—applies and permits short‑term rentals (fewer than 30 consecutive nights) with state‑level requirements. This is the operative framework until county or city rules are finalized.

1. Overview: Current STR Status in Shelton and Mason County

• Current status:
  • Mason County has never regulated STRs and does not currently regulate them. RCW 64.37 (effective July 28, 2019) is the controlling state statute.
  • County planners were directed to review local STR rules; however, the Board of County Commissioners placed the review “on hold” and indicated the STR webpage will be updated when review resumes.
  • In parallel, the County completed SEPA review for proposed draft rules (MCC 17.100) in 2024, but those proposals were not adopted at that time.
• What this means for investors:
  • STRs are permitted in Shelton/Mason County today under RCW 64.37.
  • Expect future local rules to address occupancy tied to septic capacity, operations standards, inspections, parking, waste, and a permit/renewal structure—consistent with draft concepts already discussed. Until adopted, state law and general county ordinances (building, fire, health, noise, solid waste, sewage) apply.

Source:

• Mason County STR project page notes: “The County has never regulated, nor does it currently regulate short-term rentals… review of short-term rental regulations is on hold… This page will be updated when there is an anticipated date for resuming review.”
• Mason County Journal news coverage confirms the County is moving toward potential regulations but none are currently adopted.

2. How to Start a Short-Term Rental Business in this Market Until local ordinances are adopted, follow Washington State requirements and best practices aligned to draft county themes:

• Legal framework:
  • Operate under RCW 64.37 (definitions, consumer safety, platform compliance, insurance minimums).
  • Comply with state revenue/tax obligations (refer to Washington Department of Revenue). RCW 64.37 references state tax provisions (e.g., RCW 82).
  • Ensure compliance with general county/municipal codes: building/fire safety, environmental health (septic/wastewater), solid waste, noise, parking, and zoning.
• Operational preparation:
  • Confirm septic capacity for your property (particularly relevant in shoreline/environmentally sensitive areas). Draft local rules considered capping occupancy based on approved septic capacity.
  • Prepare a Property Management Plan (PMP) covering: contact info, parking plan/site diagram, trash/waste procedures, quiet hours/noise controls, occupancy limit tied to septic capacity, fire safety/emergency info, burn-bans, and guest rules. While draft rules considered requiring county submission, state-only operation currently requires only reasonable management practices.
  • Register your listing with platforms to comply with RCW 64.37 platform obligations (customer lists, tax remittance, safety notices, etc.).
• When local rules resume:
  • Expect a multi-tier permit system (owner-occupied vs. non-owner-occupied vs. higher occupancy), annual permit renewals, initial inspection, and possible re-inspection fees if a unit fails the first inspection.
  • Expect evidence of weekly curbside solid waste service or proof of alternative lawful disposal if curbside is unavailable.
  • Expect posting/marketing requirements (e.g., site plan showing parking; on-site safety signs).

Sources:

• State statute reference via County STR page (RCW 64.37).
• Draft MCC 17.100 concepts and SEPA documents (occupancy tied to septic capacity; inspections; waste; permit tiers).

3. Required Documents, Permits, Licenses, and Guidelines Current (state-level) essentials:

• Business registration and tax compliance (per RCW 64.37 and state revenue/tax laws).
• Lodging safety: smoke/CO detectors, fire extinguishers, egress, and applicable WAC requirements.
• Solid waste: evidence of weekly service or lawful offsite disposal.
• Insurance: minimum liability coverage per RCW 64.37.
• Platform registration/requirements (customer records and tax remittance per RCW 64.37).

Anticipated, once adopted locally:

• STR permit (Type 1/2/3 classification) with annual renewal.
• Initial safety/health inspection; re-inspection fees if needed.
• Property Management Plan submission (per draft MCC 17.100).
• Parking and occupancy signage; site plan showing parking and contact info.
• Fee schedule (permit application, inspection coverage, per-night fee alternatives).

Sources:

• Draft MCC 17.100 (PAC working drafts).
• SEPA project description emphasizes occupancy based on approved septic capacity and operational standards (noise, trespassing, garbage, parking, fire/building safety).

4. Specific Regulations: County/City and State State (Washington RCW 64.37):

• Definitions: STR = lodging use, not a hotel/motel/B&B, offering a dwelling unit for fewer than 30 consecutive nights.
• Taxes and fees: Requires compliance with state tax obligations (e.g., lodging taxes) referenced in RCW 64.37 and the Revenue Title (e.g., RCW 82).
• Platform obligations: Platforms must collect/remit taxes, provide customer lists to the Department of Revenue, and comply with consumer safety requirements.
• Insurance: STR operators must carry minimum liability insurance.
• Safety/consumer protections: Appliance and safety notice requirements as specified by the statute.

County-level (Mason County) — current status:

• No county-specific STR ordinance is in effect as of the latest county update; rules review is “on hold.”
• General ordinances continue to apply (building/fire, solid waste, sewage systems, noise, traffic/parking).
• Draft MCC 17.100 (SEPA 2024) proposed:
  • Occupancy limits tied to approved septic capacity.
  • Type-based permits: Owner-occupied (Type 1), non-owner-occupied (Type 2), higher occupancy (Type 3; possibly a special use).
  • Operations standards: parking site plans, weekly waste service or proof of disposal, noise, trespass prevention, fire safety and emergency information.
  • Inspections: initial inspection, annual servicing of extinguishers, re-inspection fees if failed.
  • Permit term: one year, renewal required.
  • Violation tiers: escalating fines and potential permit revocation for repeat violations.
  • Application of regulations county-wide; consideration of HOA relationships and double enforcement limits.

Municipal (Shelton):

• No city-specific STR regulations are identified in the provided sources. As Mason County is the lead jurisdiction for unincorporated areas including Shelton, investors should follow state law and monitor county actions. If Shelton adopts its own rules, those would supersede county rules within city limits.

• PAC staff reports and working drafts for draft MCC 17.100 (meeting packet).

5. Key Compliance Themes and Practical Considerations

• Shoreline and environmental sensitivity: Concentration of STRs along waterways has raised concerns (septic overload, shellfish harvesting, beach trespassing, noise). Even without new local rules, ensure your septic system is sized/maintained for your intended occupancy and that guest behavior aligns with environmental protections.
• Occupancy and parking: Draft rules indicate occupancy will be aligned with septic capacity and require clear on-site parking. This is a likely future requirement—invest now in a clear, compliant parking and access plan.
• Enforcement posture: County commentary stresses enforcement of existing health/safety/peace ordinances. Expect continued county oversight of noise, trash, sewage, and traffic issues regardless of STR status.
• HOA and private covenants: Many developments (e.g., Lake Limerick) currently have limited or no STR restrictions; however, HOAs may update covenants. Check your HOA’s rules and note potential interactions with county enforcement.
