ADU Builder in Vista
Permitted ADUs in Vista, with a free 3D rendering before we start.
Planning a ADU in Vista? Vista has many established neighborhoods with mid-size lots and some larger hillside parcels. Proactive Edge Developments is a CSLB-licensed San Diego County general contractor. We build ADUs end to end, handle the City of Vista permit process, and include a free 3D rendering so you see the result before we start. License CSLB #768545.
Permits for a ADU in Vista
Vista regulates ADUs under Municipal Code Chapter 18.31, prohibits short-term rentals of ADUs, and has a fee waiver program for smaller units. Source: City of Vista, Vista Municipal Code Chapter 18.31.
State timeline: when there is already a home on the lot, California law (Gov. Code §66317) requires the city or county to approve or deny a complete ADU application within 60 days.
We prepare the plan set, submit it, answer plan-check corrections, and schedule every inspection through final sign-off.
What your Vista ADU includes
- Detached & attached ADUs. Standalone backyard units or additions attached to your existing home, designed to maximize rentable square footage on your lot.
- Permit & plan coordination. We manage the entire San Diego ADU permitting process — code compliance, plan checks, and approvals — so you don't have to.
- Built for rental income. Every ADU is designed around return: livable layouts, durable finishes, and a footprint that appraises and rents.
- Free 3D rendering. See your finished ADU before we build it, with our in-house design software — included free for every new client.
Featured project: the Curlew St lot split
At 3680–3682 Curlew St in San Diego, we added a second story to the main house and converted the garage into a separate unit. The owner now has two rentable addresses on one lot. It's the project we point Vista homeowners to first, because it shows our permitting, structural, and finish work in one place.
