ADU types in the recent set
Permit activity in Anaheim
Igni counted 5,270 permits issued in Anaheim over the last 12 months (Oct 2025 – Sep 2026) — down 5.9% on the 5,598 in the 12 months before. The forecast expects about 2,634 over the next 6 months.
The source's volume stepped up around February 2008 (×1.6) — likely a change in what the city publishes, so we don't compare year over year across it.
Forecast: trailing mean, typical error ±12% in backtests one to six months ahead. How we forecast
| Permit type | Last 12 months | Year over year | Forecast, next 6 months |
|---|---|---|---|
| All permits | 5,270 | Down 5.9% | ≈ 2,634 |
| Residential building | 1,196 | Down 7.5% | ≈ 600 |
| Commercial building | 562 | Up 14.5% | ≈ 282 |
| Trade (electrical, plumbing, mechanical) | 3,512 | Down 7.9% | ≈ 1,758 |

Counts are permits issued per calendar month as Anaheim 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.
How long do permits take in Anaheim?
Based on 15,625 Anaheim permits applied for between Nov 2023 and Aug 2026, the typical (median) permit was issued same day after application, and the middle half of permits took 0–55 days. One in ten took longer than 265 days.
| Permit type | Median | Typical range | Permits |

| Residential building | 67 days | 0–229 days | 3,598 |

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.
Anaheim ADU rules
Anaheim permits accessory dwelling units under California's ministerial, by-right framework — detached, attached, and conversion ADUs, plus a junior ADU — so a conforming application is approved without a hearing and within the state's 60-day deadline. A single-family lot can generally add one ADU plus one junior ADU; state law bars an owner-occupancy requirement for standard ADUs, while a junior ADU still requires the owner to live on the property.
Under the city's standards (Anaheim Municipal Code Section 18.38.015), a detached ADU is generally allowed up to 1,200 square feet, an attached ADU up to 50 percent of the primary dwelling or 1,200 square feet (whichever is less), and a junior ADU up to 500 square feet within the existing home. Detached units carry reduced four-foot side and rear setbacks, and no additional off-street parking is required when the unit is near transit, among the state's common exemptions.
Anaheim's signature offering is its ADU Express Program: for an eligible new detached ADU, a homeowner can use a state pre-approved (prefabricated) plan that California has already designed, reviewed, and approved, allowing same-day permitting at no design cost. The city maintains an ADUheim resource hub with guidance on the program and related incentives.
