Meridian, ID zoning map & districts

Meridian, Idaho's fastest-growing city, is zoned under its Unified Development Code (UDC), Title 11 of the Meridian City Code, administered by the Community Development Department. Residential zoning is organized by density (R-2 through R-40, roughly corresponding to maximum dwelling units per acre), which has allowed the city to direct the bulk of its new-build suburban growth into R-4 and R-8 subdivisions while reserving R-15 and R-40 for higher-density infill and multifamily projects near commercial corridors.

Meridian zoning map

The Meridian Community Development Department publishes the UDC text and an interactive zoning map application; parcel zoning is confirmed via the city's GIS zoning map tool.

There is no link to the official map here yet — confirm current district boundaries directly with the Meridian planning or zoning department.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Meridian

Meridian's Old Town (O-T) district covers its historic downtown core, while the Traditional Neighborhood districts (TN-C, TN-R) are applied to newer master-planned areas designed to emulate traditional walkable block patterns rather than conventional suburban subdivision layouts. Commercial development runs through a standard Neighborhood/Community/General Business hierarchy (C-N, C-C, C-G) plus a Limited Office (L-O) district for standalone office development.
