Jacksonville's Trusted ADU Builder for Northeast Florida Homeowners
Sunshine State Professional Services Inc. is a licensed ADU contractor and general contracting company serving Jacksonville and the broader Northeast Florida region. Founded in 2015, they have completed over 2,000 projects, helping homeowners across Jacksonville, Jacksonville Beach, Ponte Vedra, St. Augustine, Nocatee, and Yulee maximize their property value without having to move.
As a dedicated accessory dwelling unit builder, they specialize in custom ADU construction, home additions, and tiny homes. Their team brings deep knowledge of Jacksonville's building codes, including the 2022 ADU ordinance that expanded where ADUs can be built throughout Duval County. From design and permitting to final construction and utility connections, they manage every step of the process.
What They Build: ADU Services and Specialties
Sunshine State Professional Services offers a comprehensive range of construction services tailored to Northeast Florida homeowners:
- Detached ADU construction — Custom-built backyard cottage and granny flat units throughout Jacksonville and Duval County, designed to match the architectural style of the main home as required by local zoning.
- Garage conversion contractor services — Transforming unused garage space into fully functional ADUs, home offices, or guest suites to maximize a property's potential.
- In-law suite builder — Creating comfortable, private living spaces for aging parents or adult children, ideal for multigenerational families who want independence while staying close.
- Tiny homes — Custom-built tiny homes on existing Northeast Florida properties, suitable for backyard living, rental income, or downsizing.
- Home additions — Seamless expansions to existing homes that match the current architecture and comply with Jacksonville building codes.
All ADUs are custom-built on-site — not prefabricated — ensuring they match the homeowner's property perfectly and comply with Jacksonville's zoning requirements. Every project is also constructed to Florida Building Code standards for hurricane-resistant construction, a critical consideration given Northeast Florida's climate.
Clients receive a detailed 3D rendering of their ADU before any work begins, so they can visualize the finished result with complete confidence. Floor plan options range from compact studio layouts around 295–384 sq ft to larger one-bedroom, one-bath designs up to 624 sq ft, all staying within Jacksonville's maximum ADU size of 750 sq ft or 25% of the main home — whichever is smaller.
Understanding ADUs in Jacksonville, Florida
An accessory dwelling unit is a secondary, self-contained housing unit located on the same property as a primary residence. In Jacksonville, ADUs can take the form of a detached backyard unit, an apartment above a garage, or a converted basement. Each unit includes its own kitchen, bathroom, and sleeping area, making it a fully functional independent home.
Under Jacksonville zoning rules, ADUs must be positioned behind the main home and architecturally match the existing structure. The 2022 City Council ordinance expanded where ADUs can be built across Duval County, making them an increasingly popular option for homeowners looking to generate rental income, house family members, or add long-term property value.
Sunshine State Professional Services handles all permitting through Jacksonville's Building Inspection Division, manages contractor coordination, and provides fixed-price quotes with no hidden fees. Their typical ADU project timeline runs from 5 to 8 months, from permits through to a move-in ready certificate of occupancy.
Financing options are also available, with loan amounts up to $250,000, no home equity required, no prepayment penalties, and funding available within 1–3 days — making ADU construction accessible for a wide range of homeowners across Northeast Florida.
