Brentwood, TN · ADUs & guest housesAccessory Dwelling Units and Guest Houses in Brentwood, TN

An accessory dwelling unit is a complete small home on the same property as the main house: a place to sleep, a bathroom, a kitchen or kitchenette, and its own heating and cooling. Families build them for aging parents who want independence close by, for adult children, for long-stay guests, or as a quiet studio apart from the household. On a larger Brentwood lot the physical room for a cottage is often there. Whether one is allowed, and in what form, is the first thing to settle.

Zoning and private covenants decide that, not the size of the yard. The City of Brentwood’s zoning rules govern whether a detached living unit, a guest house without a kitchen or an attached in-law suite is permitted on a given lot, and some neighborhoods’ HOA covenants add limits of their own. JACCO looks into both before design goes far, so you are not paying for plans that cannot be approved. Where a detached unit is not an option, an attached suite with its own entrance can often deliver much of the same independence.

Once the form is settled, building an ADU or guest house is a full construction project at a smaller scale: site layout and utility routing, footings or a slab, framing, roofing, windows, insulation, plumbing, electrical and finishes. Water, sewer and power usually run from the main house or the street, and their path affects where the cottage can sit. A ductless mini-split often suits a small unit well. Exterior materials and rooflines are matched to the main house so the two clearly belong together.
