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 2,550 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
SnapADU has permitted numerous projects within the city, and we know Vista’s regulations and processes very well. Turnaround times at the city are extremely fast. But homeowners should anticipate higher permit fees (closer to $16-20/sqft for larger units), as plan check, building permit, and impact fees are not waived for ADUs >750 sqft (impact fees will be proportional to the size of the primary dwelling). To balance this, Vista does offer a fee waiver program for qualified ADUs (either for caregivers or low income).
Vista requires in-person submissions which does add some processing expense. Also, soils reports are generally required for ADUs, as well as storm water mitigation.
