Chula Vista runs an active ADU program with a published catalog of City Standard ADU Plans and an ADU Loan resource for homeowners. The Standard Plans are accepted as pre-approved by the City of San Diego as well.
Sizes align with state allowances (typically up to 1,200 sq ft for 2+ bedroom detached). Confirm exact maxima in the linked planning standards.
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.
Parking outcomes depend on site conditions and the standards referenced on the city ADU page. Use the city’s FAQs and planning standards rather than assumptions.
Submittal through Development Services. Citizen Access electronic permitting workflow available. JADU pathway requires owner occupancy and a recorded deed restriction.
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.
Cost and fees discussion sits on the ADU landing page; the city points to its ADU Loan resource for income-qualified homeowners.
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.

Standard ADUs in Chula Vista: no owner-occupancy required (made permanent in 2023).
JADUs: limited to 500 sq ft of interior livable space within an existing single-family home. Owner occupancy is required only when sanitation facilities are shared with the main house. JADUs cannot be used as short-term rentals (AB 1154 / SB 543).
Sketch a floorplan, walk through it in 3D, and have our planners review it for size, height, and setback compliance before you submit to Chula Vista.
Heads up: Local rules change frequently. This page summarizes publicly available state law (California Government Code §§ 66310–66342) and current local guidance for general planning purposes. Always confirm specifics with the Chula Vista planning desk before submitting plans. ADUMetrics does not provide legal advice.
