Multiple Two-Story ADUs Over Garages for Rental Income in Vista
Franklin Lane, Vista, CA 92084
Homeowner Story: Generate rental income
Other Features: Deck, Garage
Special Circumstance: Multiple ADUs
This project on Franklin Lane in Vista was developed to create additional rental income through a multi-unit ADU design. The homeowner chose SnapADU to guide the project from design through construction.
The proposed plan features a custom two-story ADU structure totaling 2,626 square feet, designed as multiple side-by-side rental units built over garages. With a combined total of 8 bedrooms and 6 bathrooms, the layout is optimized to maximize rental potential while maintaining comfortable, functional living spaces for future tenants. The side-by-side configuration allows each unit to feel independent while efficiently utilizing the property footprint.
Located outside the coastal zone, connected to sewer, and not subject to HOA restrictions, the property benefits from a streamlined permitting process within the City of Vista. Early planning focused on site layout, access, and building configuration to support long-term rental use and cost-efficient construction.
Designed specifically as an income-producing property, this custom ADU project reflects a strategic approach to increasing property value while delivering modern, high-quality rental housing well suited to the Vista market.

The Vista ADU Guide
Vista has become one of the more efficient jurisdictions in San Diego County for permitting ADUs with relatively fast review times. We’ve worked on numerous ADU projects throughout Vista and have developed a strong understanding of Vista’s permitting process and local requirements.
While permitting is generally quick, homeowners should plan for several city-specific considerations. Vista requires in-person permit submissions, and many projects require soils reports and stormwater mitigation. The City also has some unique zoning districts, including the Townsite Specific Plan (SP-TS), which can create questions about what is allowed on a property. Fortunately, California’s statewide ADU laws generally supersede the underlying Specific Plan, allowing qualifying properties within SP-TS to build an ADU.
Vista ADU Permitting
Most ADU permits in Vista are approved within approximately 3-5 months after submission. Permit costs generally range from approximately $8-16/sqft though larger ADUs may see permit fees closer to $16-20/sqft because proportional development impact fees apply to many ADUs over 750 sqft.
Vista requires in-person permit submissions and often requires soils reports as part of the permitting process. Stormwater mitigation is also commonly required and should be considered during site planning and budgeting.
For homeowners who qualify, Vista’s ADU Fee Waiver Program may reduce certain development impact fees for ADUs occupied by lower-income households or caregivers providing regular care to a property owner or occupant.
