What Tacoma says in its own permit handout
From Mechanical Equipment Locations, published by Tacoma. This is the jurisdiction's own guidance on its permit process, not the ordinance text — where the two differ, the code governs.
“Mechanical equipment may not be located within a required side yard setback (7.5 feet or 5 feet, depending on zone) or open yard space. In all cases, chain link fencing, with or without slats is prohibited to use for screening.”Handout ↗read 2026-09-05
