ADU rules in Escondido, CA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Escondido regulates ADUs and JADUs under Article 70 of the Escondido Zoning Code (Ch. 33, §33-1474 Development Standards). ADUs are capped at 1,000 sq ft (with the living area not exceeding 50% of the primary dwelling), and JADUs at 500 sq ft within the existing single-family structure.
Under §33-1474 of the Escondido Zoning Code (Article 70), the maximum ADU size is determined by lot size per Table 33-1474, with the living area limited to 50% of the existing or proposed primary dwelling. Detached ADUs must observe at least a 4-foot side and rear setback, and an ADU built above an existing detached garage requires a 5-foot side and rear setback. An ADU up to 16 feet tall is permitted regardless of the underlying zone's height limit. Parking is not required for ADUs under §33-1474(c)(1). ADU rentals must be for terms of 30 days or more — short-term vacation rental use is not permitted. JADUs follow Article 70 and state law: capped at 500 sq ft, located within the walls of the existing single-family dwelling, and subject to an owner-occupancy deed restriction.
Unpermitted ADUs are violations of Escondido Zoning Code Article 70 enforced by Code Enforcement, with administrative citations, daily fines, and required compliance or removal. Renting an ADU for less than 30 days violates Escondido's ADU and short-term rental rules.
