Meridian City Code Title 11, Chapter 2, Article D establishes Traditional Neighborhood Residential (TN-R), Traditional Neighborhood Commercial (TN-C), and Old Town (O-T) districts to encourage mixed-use, pedestrian-oriented development with reduced setbacks, alley access, and higher density than conventional suburban zones.
Idaho SB 1352 (effective July 1, 2026) requires cities with populations over 10,000 to allow residential development at a minimum density of 12 units per acre on tracts of 4 acres or larger, with lots as small as 1,400 square feet. Setback and lot-width requirements do not apply to qualifying starter-home subdivisions.
Meridian City Code Title 11, Chapter 4, Section 11-4-3-12 (as amended by Ordinance 25-2102, effective November 18, 2025) permits accessory dwelling units (ADUs) in all residential zones, including TN-R and O-T districts. ADUs may be attached, detached, or internal conversions, with maximum size of 900 square feet or 70% of primary dwelling, whichever is less.
TN-R district dimensional standards (UDC 11-2D-6) permit minimum lot sizes of 3,000 square feet for single-family detached, 2,000 square feet per unit for duplex, and 1,500 square feet per unit for townhomes. Front setbacks are 10 feet minimum with porches encouraged; side setbacks are 5 feet; rear setbacks are 10 feet or 5 feet if alley-loaded.
TN-R and O-T districts require 1 off-street parking space per dwelling unit for single-family and duplex uses, with parking accessed via alley where available. On-street parking may count toward requirement if approved by City Engineer. No parking required for ADUs within 1/2 mile of frequent transit service.
