ADU’s

ADU's — Accessory Dwelling Units

An ADU (Accessory Dwelling Unit) is a fully independent secondary living space on your property — attached to your home, detached in your backyard, or converted from an existing garage. ADUs add rental income potential, multigenerational living space, or a fully self-contained guest suite to your property. AG Developers handles ADU projects from zoning check through final inspection in Franklin, Brentwood, Nashville, and across Williamson County.

How It Works

Zoning & Feasibility Check

We verify your parcel's ADU eligibility under Franklin's 2025 zoning ordinance or applicable local regulations, confirm setback and size requirements, and validate owner-occupancy compliance before any design work begins. Tennessee requires the owner to occupy either the primary home or the ADU.

Design, Permits & Planning

We develop the floor plan, submit for building permits in our name, and coordinate with local planning departments. We know the Franklin and Williamson County ADU permitting process — we've done it before. TN GC License #76500.

Full Construction

Foundation, framing, roofing, mechanical, and finish work — we build your ADU from the ground up, managing every subcontractor and delivering a fully permitted, inspected, move-in ready unit.

Portfolio (Case Studies)

Detached Guest Cottage

A 720 sq ft detached ADU built on a Westhaven property — fully permitted through the City of Franklin, featuring an open living area, full kitchen, bedroom, and bathroom with a private entrance.

Attached In-Law Suite

A 900 sq ft attached ADU addition built onto an existing Franklin home — providing a fully independent living area for an aging parent with a shared wall but separate entrance, kitchen, and utilities.

Garage-to-ADU Conversion

A 2-car garage converted to a legal, fully permitted ADU in Brentwood — adding approximately $80,000–$120,000 in appraised value and immediate rental income potential.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
