San Diego Building Permit Timelines & Delays
San Diego has spent recent years restructuring how its Development Services Department (DSD) moves projects through review, leaning on ministerial (by-right) approvals and fast-track lanes. For qualifying projects the city now hits aggressive targets: more than half of all permits are issued the same day, and 100%-affordable projects clear staff review in an average of nine days against a guaranteed 30-day window.
San Diego permitting, the figures
The key published figures for this jurisdiction — each cited to its official source.
What the data shows
San Diego's Affordable Housing Permit Now program reviews 100%-affordable projects in an average of nine days against a guaranteed 30-day target, and has permitted 6,746 affordable homes over three years (City of San Diego, 2026).
More than half of all DSD permits are now issued the same day, with by-right Complete Communities lanes targeting review and issuance within 30 days for qualifying housing (City of San Diego, 2024).
Unlike Los Angeles (260 vs. 147 days) and Orange County (233 vs. 101 days), San Diego showed no statistically significant difference in average ADU permitting time inside versus outside its Coastal Zone for 2018–2022 (Terner Center, 2024).
San Diego has pivoted sharply from single-family to ADU and by-right multifamily permitting — single-family units permitted fell from 864 in 2016 to 132 in 2024 (Terner Center, 2024).
Most delay accumulates before technical review
The data points to the same lever everywhere: most delay accumulates before technical review, in completeness and resubmittal cycles. Permittable's Permit Review Diagnostic checks your plans against applicable codes and common reviewer issues before you submit — so your package is more likely to clear on the first pass.
San Diego permitting: FAQ
How long does a building permit take in San Diego?
It depends on the lane. More than half of all DSD permits are issued the same day, and 100%-affordable projects average about nine days of staff review against a 30-day guarantee (City of San Diego, 2024–2026). Larger or correction-heavy projects take longer, since those fast figures don't include multiple plan-check rounds.
Does San Diego have a fast-track for affordable housing?
Yes. Affordable Housing Permit Now guarantees review of 100%-affordable and shelter projects within 30 days, and the city reports an average staff-review time of about nine days (City of San Diego, 2026). The program had permitted 6,746 affordable homes over three years, of which 2,148 were completed and occupied.
Is the coastal zone a permitting bottleneck in San Diego?
Less than in peer regions. The Terner Center found no statistically significant difference in average ADU permitting time inside versus outside San Diego's Coastal Zone for 2018–2022, whereas Orange County averaged 233 days inside the coastal zone versus 101 days outside (Terner Center, 2024).
Where can I see current San Diego permit times?
The City of San Diego Development Services Department publishes a weekly permit-processing timeline and a permitting-center dashboard on sandiego.gov, broken out by permit type and review phase (City of San Diego DSD).

Figures come from different programs and periods and are not directly comparable: the nine-day and same-day figures apply to the affordable and by-right fast-track lanes, not typical correction-heavy projects, and the DSD weekly timeline reports only the issuance-phase queue, not end-to-end review. A widely circulated third-party “176-day average” figure lacked a verifiable primary source and was excluded.
