Building height in Kennewick is set by KMC 18.12.010 A.2 (Table of Residential Site Development Standards). Maximum height is 35 feet or 2.5 stories (whichever is less) in the RS, RL and RMH zones; 35 feet in RM; 45 feet in RH (multi-family); 30 feet in RTP. The RTP cap reflects manufactured-home park scale; the RH cap reflects multi-family scale. Tall structures near the Tri-Cities Airport are also subject to the Crash and Approach overlay in KMC Chapter 18.58 and federal FAA notice under 14 CFR Part 77.
Building height in Kennewick is governed by KMC 18.12.010 A.2 (Table of Residential Site Development Standards) of the Title 18 Zoning Code. The Max. Height row of the table sets the following residential caps: RS - 35 feet or 2.5 stories, whichever is less; RL - 35 feet or 2.5 stories, whichever is less; RM - 35 feet; RH - 45 feet; RTP - 30 feet (manufactured/mobile home park standard); RMH - 35 feet or 2.5 stories, whichever is less. The UMU (Urban Mixed Use) district handles height through KMC Chapter 18.80 and the City's design standards rather than a single residential cap. Heights in commercial, mixed-use and industrial districts are set in the corresponding non-residential tables and tied to KMC Chapter 18.06 (Districts and Maps). Kennewick adopts the State Building Code through the Kennewick Permit Center, which incorporates the WAC 51-50 series (2021 International Building Code) - IBC Chapter 5 adds construction-type and occupancy-based maximum building heights and areas that operate on top of the zoning cap. The Crash and Approach overlay in KMC Chapter 18.58 (around the Tri-Cities Airport / KPSC, Pasco) imposes additional federal- and state-aligned height limits. Tall structures may also trigger Federal Aviation Administration notice under 14 CFR Part 77 (Safe, Efficient Use, and Preservation of the Navigable Airspace). Variances are processed administratively under the Kennewick Title 18 framework. State authority is RCW 35A.63 (Planning Powers).
Building above the KMC 18.12.010 A.2 cap is a zoning violation enforceable by the Kennewick Planning Department and Code Enforcement, with refusal of a Certificate of Occupancy, stop-work orders on active construction, and citation under the general penalty provisions of the Kennewick Municipal Code. IBC Chapter 5 height violations are separately enforced by the Building Official under the State Building Code adopted at WAC 51-50. Crash and Approach overlay (KMC Chapter 18.58) height violations may also implicate federal FAA notice obligations under 14 CFR Part 77 and review by the Port of Pasco / Tri-Cities Airport.
