Counts are permits issued per calendar month as Los Angeles publishes them to its open-data feed — not a complete census; a change in what the city publishes moves them too. The current month is left out, and the most recent months are provisional. A forecast is a statistical estimate with a range, not a prediction for any project. Informational only.

Typical, not guaranteed: individual permits vary with project scope, application completeness and plan-review workload. Days are calendar days from application to issuance; applications still pending are counted as not-yet-issued rather than dropped. Informational only, not legal advice. How we calculate approval times.
Housing law — California
California mandates ministerial (by-right) approval of accessory dwelling units statewide, with a 60-day decision deadline and one ADU plus one junior ADU allowed on most single-family lots; owner-occupancy is generally not required.
SB 9 allows by-right duplexes and urban lot splits on single-family lots, and newer transit-oriented upzoning (SB 79) phases in from 2026.
Los Angeles ADU rules
Los Angeles follows California's statewide framework, under which a conforming accessory dwelling unit is approved ministerially — without a public hearing or discretionary review — and the city must act within 60 days of a complete application. Most single-family lots can add one ADU plus one junior ADU (JADU), and the city permits detached units, attached units, garage or interior conversions, and JADUs.
State law bars an owner-occupancy requirement for ADUs permitted on or after 2025, so an owner can rent both the main house and the ADU; a junior ADU still carries an owner-occupancy condition. Detached ADUs are generally allowed up to 1,200 square feet, and no additional off-street parking is required when the ADU is within a half-mile of transit, among other common exemptions.
Los Angeles is best known for its ADU Standard Plan Program, run through the Department of Building and Safety: private architects pre-clear complete ADU designs for code compliance, so an applicant who picks an approved plan faces a much shorter plan check that covers only site-specific items. The city even offers a free standard plan ('YOU-ADU') at no design cost.
