Escondido, CA Accessory Structures: ADU Rules (2026)

Article 70 of the Escondido Zoning Code (Municipal Code §§ 33-1470 through 33-1480) governs both accessory dwelling units (ADUs) and junior accessory dwelling units (JADUs) citywide. One ADU is permitted on any lot zoned for single-family or multifamily use per § 33-1471, alongside a JADU under § 33-1473(a). 2(e), plus up to two detached ADUs. Development standards in § 33-1474 require the city to allow at least an 850-square-foot ADU, and 1,000 square feet for units with more than one bedroom on lots of 20,000 square feet or larger, even where lot coverage, floor-area-ratio, or minimum-lot-size rules would otherwise block it.

Side and rear setbacks are capped at four feet; front setbacks follow the underlying zone. Converted existing structures need no setback at all and may expand up to 150 square feet for entry access. Height is capped at the zone limit, but a 16-foot ADU is always allowed regardless of that limit. The city cannot impose off-street parking requirements on an ADU or JADU, and replacement parking is not required when a garage is demolished to build one. Single-family ADUs need only a building permit; ADUs on multifamily properties need an ADU permit reviewed under § 33-1472.

The director of community development must approve or deny complete applications ministerially within 60 days per § 33-1477. Design must match the primary residence's roof form, materials, color, and texture, and the unit needs its own street-visible address per § 33-1474(d)-(e).
