Bellevue’s mild summers help here: Sand Point normals show only about two days a year at 90°F or above, so a large, ventilated room beside the closet has a better chance of staying under the 85°F exhaust limit than in hotter places. An upstairs room in a heat wave still needs checking, and a closet beside another closet is still not an option.
Inside city limits, Bellevue asks for a permit when a remodel creates new walls or turns a basement into living space, and when circuits are added or moved; the city also issues its own electrical permits rather than leaving them to Washington L&I. A conversion that adds a circuit for the cooling unit needs an electrical permit; we confirm the rest with Bellevue Development Services.
