You’re weighing options for your growing household and your property, and the signals are usually clear.
Adult children moving back home or aging parents relocating in need their own space, not a shared bedroom. A JADU gives everyone independence under one roof.
An attached garage, oversized bonus room, or underused addition can often convert directly into a qualifying Junior ADU without major new construction.
A JADU creates a legally rentable unit using space you already own, generating income without the cost of a detached structure or new lot.
Florida's ADU-friendly zoning rules have expanded recently, but county ordinances can tighten again. The sooner you plan, the more options you lock in.
Every Florida property is different, so we specialize across the primary Junior ADU approaches to match your home’s layout and goals.
We reconfigure existing interior square footage, like a bedroom suite or bonus room, into a fully self-contained unit with its own entrance, kitchenette, and bathroom.
A compact addition built against an existing wall, giving you new square footage with a separate entrance while minimizing disruption to your home's main living areas.
We convert part or all of an attached garage into living space, often preserving a portion for storage or parking while meeting FL setback requirements.
Designed around Florida's typical size caps, this compact studio layout maximizes functionality in a small footprint, ideal for single occupants or rental use.
