Home additions in San Diego: common questions
How much does a home addition cost in San Diego?
A room addition in San Diego typically runs in the five to six figures, while a detached ADU reaches the mid six figures. Foundation work, finishes, and the San Diego permit path drive the number. See the ranges above.
How long does an addition take to build in San Diego?
Most additions run 3 to 8 months from permit to final, longer for an ADU. Design and the San Diego permit review often take as long as the build itself, so plan for both.
