Summary
In unincorporated Cowlitz County, buildings over 35 feet tall must not exceed what the local fire district's equipment can reach, under CCC § 18.10.570. Outside any fire district, the flat cap is 35 feet. Certain rooftop features like chimneys and towers are exempt under § 18.10.670.
§ 18.10.570. Building height standards. The maximum height of buildings exceeding 35 feet in height shall be no greater than the capability of the fire abatement equipment of the Fire District in which the building is located. Buildings not located in a Fire District shall not exceed a building height of 35 feet. § ... 18.10.670. ... Exception of building height limitations. The following types of structures or structural parts are not subject to the building height limitations of this chapter: chimneys, belfries, church spires, cupolas, domes, elevator shafts, fire and hose towers, monuments, observations towers, radio station towers, smoke stacks, transmission towers, water towers, windmills and other similar projections.
Full Breakdown
10 CCC. Any building over 35 feet is capped at whatever height the fire abatement equipment of the Fire District serving that parcel can reach, tying the limit to the local fire district's ladder truck and pumper capabilities rather than a flat citywide number. If the parcel sits outside any organized Fire District (true for parts of the unzoned rural county), the building may not exceed 35 feet at all, full stop. 05 CCC building code adoption) alongside plan review by the applicable fire district.
670 carves out a specific list of exempt structural elements from these height limits: chimneys, belfries, church spires, cupolas, domes, elevator shafts, fire and hose towers, monuments, observation towers, radio station towers, smoke stacks, transmission towers, water towers, windmills and similar projections. Those elements can rise above the 35-foot line without triggering a variance because the ordinance treats them as accessory projections rather than habitable building mass. Property owners planning a structure near the 35-foot threshold should confirm with Building and Planning which Fire District, if any, covers the parcel, since that determines whether the fire-equipment-capability standard or the flat 35-foot cap governs.
The rule sits in Article IX of the Land Use Ordinance among other supplementary development standards, and it applies countywide across the zoned and unzoned areas alike, not to any single district like RR-1 or SR.
Violations & Fines
Building without a permit that conforms to CCC § 18.10.570 is enforced under CCC § 18.10.770: it is a civil infraction to violate the Land Use Ordinance chapter, processed under Chapter 2.06 CCC, and every violation is also declared a public nuisance. Each day the noncompliant structure remains is treated as a separate violation, and paying a penalty does not excuse the owner from still bringing the structure into compliance.
