Which codes and exemptions should I review?
Mono County’s current 2025 design-criteria sheet identifies the 2025 California Administrative, Building, Residential, Electrical, Mechanical, Plumbing, Energy, Fire, Existing Building, Historical Building, Green Building Standards, Referenced Standards, and Wildland-Urban Interface codes for the 2026 cycle. Local criteria include Seismic Design Category D, Climate Zone 16, 18-inch minimum frost depth, WUI defensible-space and fire-resistive provisions, and location-specific ground and roof snow loads. The county states that cosmetic work such as painting, carpeting, wallpaper, cabinets, and trim generally does not require a building permit. Permit applications distinguish full, minor, and over-the-counter work; the county’s current page also identifies qualifying alternative-energy fee waivers and prescriptive designs. Other repairs, alterations, remodels, additions, new structures, and trade work may require permits, and zoning, WUI, fire, utility, and grading requirements remain applicable.
