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