How a Chula Vista ADU gets approved and paid for
The City of Chula Vista Development Services Department handles ADU permits for Chula Vista addresses. City of San Diego and County rules do not apply, so check fees and requirements with Chula Vista directly.
State law still applies. It limits impact fees on smaller ADUs and requires cities to act on a complete application within a set review period. Confirm with the city.
Most owners then pay with home equity or a construction loan, depending on how far their equity stretches.

What drives Chula Vista ADU cost
Cost follows the unit type first. A garage conversion reuses existing structure, while a detached unit needs a foundation and more construction. Lot slope, the distance to sewer and water, and the size of your electrical panel all move the number.
| Cost line | What moves it |
|---|---|
| Design and plans | Custom design or a ready made plan |
| Permits and fees | Chula Vista's fee schedule and unit size |
| Site work and foundation | Slope, soil and access |
| Utility connections | Distance to sewer and water, and panel upgrades |
| Construction | Unit type, size and bathrooms |
| Finishes | Cabinets, fixtures and flooring |
Typical price range
A written estimate from a builder who has walked your lot is the most reliable number you can get. Ask for it broken down by the lines above so you can match it to a loan.
Choosing how to pay
Strong equity often points to a HELOC. Thin equity points to a construction loan that lends on the finished value. A garage conversion can keep the budget smaller.
