Dublin, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Maximum building heights in Dublin are set by the Zoning Ordinance, Chapter 8.36 (Development Regulations). For the R-1 single-family residential district, the maximum height is 25 feet and 2 stories west of Dougherty Road, which may be increased to 35 feet and 2 stories with Site Development Review approval, and 35 feet and 2 stories east of Dougherty Road. The Dougherty Road dividing line reflects the older, lower-scale neighborhoods of western Dublin versus the newer eastern development areas. The chapter also addresses height on sloping lots: for residential exceptions, the maximum allowed height for a dwelling on a site with a slope between 15 and 22.5 percent may be increased by the same proportion that the actual site slope exceeds 15 percent. Height is generally measured to the standards defined in the Zoning Ordinance, and certain roof and wall features may project as allowed. Because a large portion of Dublin is zoned Planned Development (PD), many homes are subject to height limits in their adopted PD plan rather than the base R-1 numbers, and accessory structures and accessory dwelling units carry their own height rules in Chapters 8.40 and 8.80.
