Single-family dwellings in Union City are limited to 30 feet and two stories above average adjoining grade. Most multi-family RM districts also cap height at 30 feet, while the RM 1,500 district allows up to 75 feet.
Per the Union City Residential Zoning Districts Development Standards (UCMC Title 18), maximum building height is 30 feet in the RS 6,000, RS 4,500, R-5000, RM 3,500, and RM 2,500 districts. One-family dwellings are restricted to a maximum of two stories above the average adjoining grade of the property, or 30 feet, whichever is less. The higher-density RM 1,500 district permits a maximum height of 75 feet. Where the table and the Title 18 Zoning Ordinance conflict, the Zoning Ordinance controls. Fence height is governed separately under Chapter 18.32.
Construction exceeding the district height limit requires a variance or must be lowered. Stories and grade measurement are determined per the Zoning Ordinance.
