Accessory dwelling units and garage conversions are one of Jacksonville's fastest-growing renovation trends. Here is how to size your dumpster for an ADU or garage-to-living project.
Dumpster Rental for ADU and Garage Conversion Projects in Jacksonville FL
Accessory dwelling units (ADUs) — also called in-law suites, guest cottages, and backyard homes — are one of the fastest-growing construction trends in Jacksonville FL. Whether you are converting a detached garage, adding a second-story apartment above a garage, or building a backyard cottage from the ground up, the construction generates significant debris that a roll-off dumpster handles most cost-effectively.

ADU Project Types and Dumpster Needs in Jacksonville
Attached garage conversion to living space.
Converting an attached garage — the most common ADU type in established Jacksonville neighborhoods — involves removing the garage door and frame, insulating walls and ceiling, installing HVAC stub-outs, and finishing the interior. A 15-yard dumpster ($349) handles the demo and framing debris from a standard 2-car garage conversion.
Detached garage conversion.
A detached garage conversion typically involves similar demo scope plus separate electrical and plumbing tie-in work. A 15-yard ($349) or 20-yard ($399) handles the full project depending on structural modifications.
New backyard cottage construction.
New ADU construction generates less demo debris than conversions (no existing structure to remove) but still produces formwork, framing cutoffs, packaging, drywall scrap, and general construction waste. A 15-yard ($349) typically handles new ADU construction debris for a 400–600 sq ft unit.
Second-story garage apartment.
Above-garage apartment additions involve more structural and mechanical work — floor framing, stair access, full MEP rough-in, drywall, and exterior finish. A 20-yard ($399) is the right call for most second-story additions.

Jacksonville ADU Rules Affecting Dumpster Placement
Under current Jacksonville zoning (DIA and City of Jacksonville Planning), ADUs are permitted in most residential zones, and construction activity permits temporary equipment storage on the property during active construction.
HOA restrictions apply. If your property is in an HOA community, construction dumpsters are usually permitted during active permitted construction but may be restricted in duration or placement. See our HOA rules guide for details.
Right-of-way placement. If the construction site is on a smaller lot without staging space for a dumpster, a Duval County right-of-way permit allows street placement during active construction. We can advise on the permit process.
