An accessory dwelling unit (ADU) is one of the smartest investments a Florida homeowner can make — adding rental income, housing for family, or long-term resale value. JAS Construction Group handles every phase of ADU construction: site evaluation, architectural plans, Volusia County permits, foundation, framing, mechanical, and finish work. As a licensed Florida General Contractor (#CGC1525668), we manage the entire project so you never have to coordinate multiple trades.
ADU Types We Build
Detached ADU / Granny Flat
A fully independent structure in your backyard with its own entrance, kitchen, bathroom, and living space. Ideal for rental income or multigenerational living.
Attached In-Law Suite
An addition connected to your main home with a private entrance — perfect for aging parents or adult children who want proximity without sharing a front door.
Garage Conversion ADU
Convert an attached or detached garage into a fully permitted living unit. One of the most cost-effective ADU paths available to Florida homeowners.
Interior Conversion
Transform an underused basement, bonus room, or large suite into a self-contained unit with a separate entrance and full amenities.
Junior ADU (JADU)
A smaller unit carved from existing square footage — typically 150–500 sq ft — with a kitchenette and private or shared bath.
Two-Story Addition with ADU
Add a second story to your home with a dedicated ADU level — maximizing your lot without expanding your footprint.
Why Build an ADU in Florida?
Rental Income
A permitted ADU can generate $1,200–$2,000/month in rental income in Volusia County, offsetting your mortgage or funding retirement.
Multigenerational Living
Keep aging parents or adult children close while maintaining everyone's privacy and independence.
Increased Property Value
A permitted, well-built ADU adds significant appraised value — often returning more than the construction cost.
Florida-Friendly Zoning
Florida state law (HB 1339) has made ADU permitting more accessible. We know Volusia County's specific requirements inside and out.
How Our ADU Build Process Works
Site Evaluation & Feasibility
We assess your lot size, setbacks, utility connections, and Volusia County zoning to determine what ADU type is possible and what it will cost.
Design & Architectural Plans
We work with licensed designers to produce permit-ready drawings — floor plans, elevations, and site plans tailored to your property.
Volusia County Permitting
We submit and manage all permit applications, respond to plan review comments, and schedule all required inspections.
Construction
Foundation, framing, roofing, plumbing, electrical, HVAC, insulation, drywall, and all finishes — managed by our licensed GC team.
Final Inspection & Certificate of Occupancy
We see the project through final inspection and obtain the Certificate of Occupancy so your ADU is fully legal and insurable.
