ADUs in Chula Vista
In Chula Vista, building permits are subject to development impact fees in addition to permit fees, so an ADU budget should plan for both [1]. The City bases permit costs on the size and complexity of the project, the value of the work, other permits needed, review time, and inspections [1].
Chula Vista's preapproved ADU plans are also accepted by the City of San Diego [2]. Ask your contractor whether a preapproved plan fits your lot.
FAQ
When do I pay ADU fees in Chula Vista?
The City says you pay an intake fee and full plan review fees before your plans are reviewed, and all final fees before the permit is issued [1]. You may defer development impact fees until final inspection, but those fees go up every October 1 [1]. Waiting could cost more.
How can I estimate my Chula Vista ADU fees?
The City recommends a pre-application meeting for a more accurate fee estimate, and it takes fee questions by email [1]. Give detailed project information, such as size and type, for the best estimate.
