Jax Tiny Homes

Jax Tiny Homes is a Jacksonville-based, licensed general contractor specializing exclusively in Accessory Dwelling Units (ADUs), garage conversions, and pool house ADUs throughout Northeast Florida. Founded by Marc Cousins, the company was created to simplify the ADU process by providing homeowners with a single contractor who manages everything from property evaluation and permitting to final construction. By focusing solely on site-built ADUs, Jax Tiny Homes delivers permanent, code-compliant backyard homes designed for multigenerational living, rental income, and aging-in-place solutions.

Operating as a full-service design-build company, Jax Tiny Homes handles zoning research, custom floor plans, engineering, permitting, utility coordination, construction, inspections, and certificate of occupancy. Every home is stick-built on-site, engineered for Florida wind loads, and inspected throughout construction. The company emphasizes transparent pricing, fixed-price contracts, and turnkey project delivery, allowing homeowners to move into a completed ADU without coordinating multiple contractors.
