Local review conditions

What sets a Alhambra project apart.

These are the conditions on record for Alhambra. Each one changes the design, the studies or the agencies involved — and each one still has to be confirmed for the exact parcel.

Recorded parameters

Typical local figures for Alhambra.

Typical editorial values — not a quote and not an official determination. Verify each figure with the city before deciding anything.

Maximum ADU size

1,200 sq ft detached; attached limited by the primary dwelling (state floor, Gov. Code § 66321)

Height limit

16 ft detached; up to 18 ft within ½ mile of a major transit stop; up to 25 ft attached (Gov. Code § 66321)

Rear / side setbacks

Owner occupancy

State law generally prohibits ADU owner occupancy, with a qualified-buyer sale exception. Alhambra's November 2025 handout describes JADU occupancy and a recorded deed restriction; under current § 66333(b), occupancy applies when sanitation is shared, subject to ownership exceptions. Confirm the city's current handout.

JADU rules

Short-term rental

Not stated in the city's ADU handout; confirm rental rules with the Planning Division

Fire sprinklers

Only required if the primary dwelling has sprinklers (Gov. Code § 66314)

Solar PV

Newly built detached ADUs fall under the Title 24 solar PV requirement

Construction hours

Set by the city noise ordinance; confirm the current window with the city

Local detailAlhambra reviews an ADU across several divisions and publishes an itemised fee list: separate Public Works, Fire Department, Planning and Utilities plan-check fees, an ADU address-assignment fee per building, school-district fees, and a higher utilities improvement fee when a new water meter is needed. The Building Division handout also states that converting a permitted garage is a change of use from U to R-3, so the structure must be brought up to current code for fire-resistive construction, light, ventilation, ceiling height, egress and alarms — not only new partitions.
