Escondido ADU Regulations

• ✓Pre-Approved ADU Program (PAADU) with downloadable plans
• ✓Citywide no-parking policy for ADUs (more permissive than state baseline)
• ✓Explicit 1,000 sq ft cap on standard ADUs (stricter than some neighbors' 1,200 sq ft)
• ✓Short-term rentals banned — 30-day minimum lease required

Standard ADUs up to 1,000 sq ft. JADUs up to 500 sq ft. JADU expansions for ingress/egress are limited to 150 sq ft beyond the existing footprint.

State guarantee: California requires every city to allow at least an 800 sq ft ADU exempt from local lot coverage, FAR, and front-setback rules.

Height baseline: 16 ft for detached, rising to 18 ft within ½ mile of major transit. Attached ADUs follow the primary home, capped at 25 ft.

No ADU parking required — citywide policy under Ord. Sec. 33-1474(c)(1).

Standard versus multifamily tracks. Digital submittal coordinated through Building (buildingpermits@escondido.gov), with ProjectDox for plan review.

State backstop: A complete ADU permit must receive a decision in 60 business days. If the city stalls past 30 business days, AB 253 lets you hire a certified private plan checker to force a 10-business-day decision.

PAADU plans are marketed as a cost and time saver. Confirm fee schedule with Building.

SB 543: No impact fees on ADUs ≤750 sq ft. Above 750 sq ft, fees scale to the ratio of ADU size vs the main home.
