Notes on the mix
New construction accounts for 207 permits, roughly one in four, at a median of 975 square feet and $120,000 declared. Conversions are declared at $97 per square foot, against $98 for conversions citywide. JADUs are priced lower, at $82 per square foot.
Which route suits a house depends on the lot and the existing structure, and this comparison of ADUs, JADUs and conversions is a good starting point. The permits themselves are all handled by LADBS; the process guide explains how.
City comparison
For all ADU permits, the median declared valuation is $60,000 here and $60,000 citywide, the median size is 600 versus 558 square feet, and the median time to permit is 119 versus 154 days. After issue, the median to CofO is 328 days here and 368 for the city. New units get their permits in 177 days here against 213 citywide.
Completion status
Of 880 permits, 601 show a certificate of occupancy, about 68 percent. The post-permit median is based only on the 601 permits with a CofO.
Where the numbers come from
We flagged ADU permits from the permit's ADU fields and descriptions and set aside supplemental permits. Declared valuation is what the applicant wrote on the permit and not the full project cost; design, fees, utilities and finishes are frequently extra. Day counts are medians for the permits that reached each step. 2026 is a partial year.
