Plumas County, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Building height in unincorporated Plumas County is regulated zone by zone in Title 9, Chapter 2, with each district's 'Height' section stating its maximum. A 35-foot maximum applies in several common zones: no structure in the Suburban Zone (S-1) may exceed 35 feet (Section 9-2.1503), and the same 35-foot cap applies in the Secondary Suburban Zone (S-3) and the Rural Zones R-10 and R-20. The 35-foot residential ceiling even carries into industrial areas: in the Heavy Industrial Zone (I-1), no timber-product manufacturing structure may exceed 125 feet and no other structure may exceed 75 feet, except dwelling units, which are limited to 35 feet. Because each zone article states its own height limit, parcels in single-family residential (2-R, 3-R, 7-R), multiple-family (M-R), agricultural, timber, and commercial zones should be checked against that zone's specific 'Height' section. Height is generally measured per the zoning ordinance's definitions, and accessory structures, towers, and similar features may have separate treatment. To confirm the exact height limit and how it is measured for your parcel, identify the zoning district and review that zone's height section, or contact the Plumas County Planning Department.
