Showing ordinances that apply to Lake Holm, WA
Lake Holm is an unincorporated community (population 3,430) in King County, Washington. Because Lake Holm is not an incorporated city, it does not have its own municipal code. Instead, King County ordinances apply directly to properties here. The occupancy limits rules below are the ones that govern your area.
Unincorporated King County applies Washington State Building Code and KCC 16.04 to STR occupancy. A common rule is two guests per bedroom plus two additional, subject to egress and 70 sq ft minimum bedroom rules.
King County does not have a standalone occupancy cap for short-term rentals in unincorporated areas. Instead, occupancy is governed by the Washington State Building Code adopted in KCC 16.04 and the International Residential Code and International Property Maintenance Code standards, which control sleeping room size, ceiling height, and egress. A bedroom must generally be at least 70 square feet, with a minimum dimension of 7 feet in any direction, a closable door, and at least one emergency escape and rescue opening (window or door) meeting minimum size standards for egress. A common industry rule of thumb used by hosts is two guests per bedroom plus two additional guests, though this is not a specific county code. Hosts must ensure the total number of occupants does not exceed what the home safely accommodates — for example, sleeping guests in living rooms or converted garages that lack emergency egress may violate building code. Septic systems on properties not connected to sewer (common in rural unincorporated King County) have design capacities based on bedroom count, and exceeding those can strain the system and violate Public Health Seattle and King County septic rules. Incorporated cities within King County, particularly Seattle, have specific occupancy caps for STRs that differ from unincorporated county standards.
Overcrowding that violates building code egress standards can result in code enforcement action under KCC Title 23 with civil penalties starting at $100 per day. Septic system overloading due to excessive occupancy can trigger Public Health Seattle and King County action and required septic repairs at the owners expense.
