ADU Construction Services by Greenland Development Group
As housing demand continues to grow across Florida and multigenerational living becomes more common, homeowners are increasingly exploring accessory dwelling unit construction as a practical way to add living space. An ADU is a self-contained residential structure located on the same lot as a primary home, and it can serve a range of purposes — from housing family members to generating rental income.
Greenland Development Group is a licensed Florida-based ADU contractor offering full-service construction for homeowners looking to build or convert space on their property. Their services cover everything from initial planning and permitting through to final inspection and handover.
Common types of ADUs they work with include:
- Detached ADUs — separate structures such as guest houses or casitas
- Attached ADUs — built as an extension of the existing home
- Garage conversion — existing garages converted into livable spaces
- Above-garage units — new construction built above an existing garage
- In-law suites — designed for multigenerational living arrangements
Florida municipalities have been gradually relaxing zoning regulations to support more ADU development, particularly in areas where housing supply is limited. This makes it a relevant time for homeowners to assess whether their property qualifies.
What the ADU Construction Process Looks Like
Greenland Development Group follows a structured process to take a project from concept to completion. Before any construction begins, they conduct a site feasibility assessment to determine whether a given lot meets local zoning requirements. Key factors they evaluate include lot size, setbacks, zoning district, maximum unit size, parking requirements, and any occupancy restrictions.
Once eligibility is confirmed, the process typically moves through the following stages:
- Initial Consultation — goals, budget, and timeline are discussed and the property's ADU potential is assessed
- Site Evaluation & Design — zoning research is completed and design options are proposed
- Permitting & Approvals — the team manages the permitting process with the local municipality
- Construction — covers site preparation, foundation, framing, utilities, roofing, and finishes
- Final Walk-Through & Certificate of Occupancy — inspections are completed and the unit is handed over
Most ADU projects take between 4 and 8 months from consultation to completion, depending on the scope of work and local permit timelines. Greenland Development Group works proactively with city and county offices to help minimize permitting delays where possible.
Costs, Financing, and Practical Considerations
ADU construction costs in Florida vary depending on a number of factors, including location, square footage, site conditions, distance to existing utilities, design complexity, material choices, and local permitting requirements. Because of this variability, Greenland Development Group provides project-specific estimates during the planning phase rather than offering blanket pricing.
For homeowners looking at financing options, common approaches include:
- Home equity loans or HELOCs
- Cash-out refinancing
- Construction loans
- Private lending
The company can connect clients with local lenders familiar with ADU-specific lending requirements.
On the question of utilities, not all ADUs require separate metering — some share water, sewer, and power with the main house, while others are set up independently. Regarding rentals, most Florida municipalities allow ADU rentals, though short-term rental rules vary by city. Greenland Development Group helps clarify applicable local guidelines during the planning process.
As a licensed and insured ADU builder operating in Central Florida, Greenland Development Group offers end-to-end project management — from design and permitting through to construction completion — for homeowners considering adding an accessory dwelling unit to their property.
