Vista is one of the few jurisdictions with a true ADU Fee Waiver Program — qualifying low-income or caregiver applicants get many city development impact fees waived in exchange for a 10-year affordability covenant.
City ties fee waiver eligibility to smaller ADUs under SB 13 (often discussed under the 750 sq ft threshold). Verify full buildable size limits in Community Development zoning.
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 per applicable zoning and SB 13 / state standards enforced at building permit.
Covenant Agreement Restricting Occupancy and Rents submitted with plans. Building Division 760-639-6108. Housing 760-639-6191. covhousing@vista.gov.
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.
ADU Fee Waiver Program waives many city development impact fees when covenant and income/caregiver tests are met for 10 years post-CO.
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 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).
