Meridian Unified Development Code (Title 11)
Meridian's zoning ordinance is the Unified Development Code (UDC), codified as Title 11 of Meridian City Code. The UDC consolidates zoning districts, district regulations, applicable-to-all-districts standards, and subdivision rules into a single title and is administered by the Community Development Department's Planning Division. The UDC defines Meridian's residential R-2, R-4, R-8, R-15, and R-40 districts as well as commercial, industrial, and traditional neighborhood overlay zones.

Under the Meridian UDC an accessory dwelling unit is permitted with a Community Development permit. The maximum size is 900 square feet or 50% of the primary dwelling, whichever is less. Setbacks are governed by the underlying zoning district's standards (Title 11 Chapter 2) rather than a single citywide ADU setback rule.

Meridian's UDC is enacted under the authority of the Idaho Local Land Use Planning Act (LLUPA), Idaho Code Title 67 Chapter 65. LLUPA delegates police power to municipalities to adopt comprehensive plans, zoning ordinances, and subdivision rules. Because Idaho has no statewide ADU preemption (unlike Colorado or Utah), Meridian's UDC retains broader local discretion over ADU size, occupancy, and parking standards than its counterparts in neighboring states.
