Summary

Maximum building height in unincorporated Pierce County is set by zone. Residential zones such as Suburban Residential (SR), Residential Resource (RR), and ROC are capped at 35 feet, while rural zones like R5 through R40 allow 40 feet. Denser and commercial zones permit more.

City-specific rules exist: Lakewood, and Tacoma have their own structure height limits rules that differ from Pierce County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

The height of a building is the vertical distance from the average elevation of the finished grade on each wall of a building to the top of a flat, shed, or mansard roof, and the average distance between the bottom of the eaves to the highest point of a pitched, hipped, gambrel, or gable roof.

Full Breakdown

Table 18A.15.040 caps maximum building height by zone: ROC, RR, and SR at 35 feet; ARL, FL, R5, R10, R20, R40, and similar rural zones at 40 feet; MHR, HRD, and Middle Housing at 45 feet; and mixed-use, employment, and center zones at 55 to 65 feet. Building height is measured from the average finished grade on each wall to the top of a flat, shed, or mansard roof, or to the average between eaves and ridge on a pitched roof. Spires, chimneys, antennas, and rooftop mechanical equipment may project above the limit under stated conditions. Community-plan overlays can be more restrictive.

Violations & Fines

Exceeding the zone height limit without a variance is a zoning violation. Enforcement can require redesign, a stop-work order, or removal of the over-height portion before a permit is finalized.
