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

Building height in unincorporated Mono County is governed by Section 04.110 of the General Plan Land Use Element. Section 04.110(1) provides that all buildings and structures designed or erected, including existing buildings that are reconstructed, altered, moved, or enlarged, shall have a height no greater than 35 feet from grade, measured from any point of the building. This 35-foot ceiling is reflected consistently across residential designations such as Rural Residential, Estate Residential, and Rural Mobile Home, each of which lists a 35-foot maximum building height. Accessory buildings in residential designations are held to a lower limit: Section 04.110(2) caps them at a maximum height of 20 feet, except as may be permitted by the Director, allowing some discretion for taller accessory structures. Certain non-building structures have separate allowances; for example, public utility poles are allowed in all districts to a height greater than that permitted for buildings but shall not exceed 60 feet. Specific designations or specific plans may modify these figures, so confirm the standard for your parcel. These limits apply to unincorporated areas; the incorporated Town of Mammoth Lakes sets its own height limits.
