Lynnwood adopts the International Swimming Pool and Spa Code (ISPSC) by reference under Lynnwood Municipal Code 16.24.010, as amended by the Washington State Building Code Council. Residential pools and spas more than 24 inches deep require a barrier at least 48 inches high with self-closing, self-latching gates, openings that will not pass a 4-inch sphere, and maximum 4-inch ground clearance. A building permit is required.
Washington WAC 246-260 regulates public spas and hot tubs at hotels, apartments, gyms, and HOAs, requiring permits, water testing, temperature limits, and posted bather safety warnings under RCW 70.90 statewide.
Dogs in Lynnwood must be on a leash, cord, or chain no longer than eight (8) feet whenever off the owner's property. Lynnwood Municipal Code (LMC) 6.02.015(H) defines 'at large' as being off the premises of the owner and not under the immediate control of the owner, an immediate family member, or an authorized person by means of a leash, cord, or chain not longer than eight feet. LMC 6.02.070 prohibits domestic animals from running at large within the city, with an exception for designated dog training/off-leash areas. Lynndale Park (18927 72nd Ave W) hosts the city's only fenced off-leash dog area, open dawn to dusk seven days a week. Voice control alone does not satisfy the leash requirement; the animal must be physically tethered by a leash of 8 feet or less.
Washington State RCW 16.30 prohibits keeping certain dangerous wild animals as pets. LMC §21.42.400 restricts livestock in residential zones (no mink, goats except miniature breeds, foxes, or hogs). Snohomish County animal control handles exotic animal concerns.
Beekeeping is regulated at the state level under RCW 15.60 (Washington State Department of Agriculture). Hive registration with WSDA is required. Lynnwood has no specific beekeeping ordinance; consult the Planning Division for any applicable setback or zoning requirements in residential zones.

Under LMC 21.18.800, each single-family dwelling unit must provide on-site parking for two motor vehicles, sized per LMC 21.18.700. STR operators must make those required spaces available to guests rather than block them off, and on-street parking is subject to the Lynnwood Police Department's standard residential parking rules. Confirm any current STR-specific parking expectations with Lynnwood Development & Business Services at 425-670-5400.
Lynnwood has no stand-alone short-term rental ordinance and no published guests-per-bedroom cap. State law (RCW 64.37) defines a short-term rental as fewer than 30 consecutive nights and sets baseline operator duties. LMC 21.02.100 defines a boarding/lodging/rooming house as serving nontransient persons, so transient STR use is not the same use category. LMC 21.42.110 governs ADUs and home occupations in single-family zones but does not address STRs. Operators must hold a Lynnwood Title 5 general business license and register with the WA Department of Revenue. Confirm zoning eligibility with Development & Business Services at 425-670-5400.
