The last two columns are days. 62 percent of Van Nuys permits are conversions; 22 percent are new units.

Larger than the city norm

Units here run large. The median permit is 639 square feet, compared with 558 citywide, and conversions here run 565 square feet against 496 for the whole city. New construction has a median of 1,100 square feet, versus 813.

Median time from submission to permit is 140 days here, below the citywide 154. After the permit, the median is 335 days to a CofO, versus 368 for the city. Declared valuation is the same as the citywide median at $60,000.

If you are thinking about turning an existing garage into living space, which is the most common route in the area, start with the conversion comparison. The agency that issues every one of these permits is LADBS, and its steps are described in the permit process guide.

Citywide medians for reference

All ADU permits in the city: $60,000 declared, 558 square feet, $105 per square foot, 154 days to permit and 368 more to CofO. For Van Nuys: $60,000, 639 square feet, $100, 140 days and 335 days.

Finished versus in progress

A CofO is on record for 671 of the 993 permits, which is 68 percent. The timing medians draw only on those. New units: 146 of 223 (65 percent) have a CofO, so treat their post-permit figure as a looser guide than the conversion one (430 of 615).

Where the numbers come from

This page counts a permit as an ADU when its ADU flags or description say so, and ignores supplemental permits. Valuation means the value declared by the applicant on the permit, which is not what the whole project costs; design, fees, utilities and finishes frequently sit outside it. Durations are medians, only for permits that got as far as each step. 2026 is a partial year.
