The City of Orange regulates maximum building heights under OMC Title 17 (Zoning). Residential zones generally limit structures to 35 feet or two stories, with ADUs limited to 16 feet. The Old Towne Historic District may impose additional height restrictions.
Under OMC Title 17, maximum building height varies by zoning district. Most single-family residential zones limit primary structures to 35 feet or two stories. ADUs are limited to 16 feet per OMC Chapter 17.29. Garage doors exceeding 8 feet in height that are visible from the street may require a minor site plan review. Within the Old Towne Historic District, design review may further restrict building height to maintain neighborhood character. Commercial and mixed-use zones have different height limits. Height is measured from average finished grade to the highest point of the structure. Chimneys, antennas, and similar appurtenances may exceed the height limit within specified parameters.
Exceeding maximum height limits may result in denial of building permits, stop-work orders, required modification, or demolition of non-conforming portions.
