Accessory Dwelling Units (ADU) in North Avondale, Cincinnati, OH

Among the most promising in the city — genuinely large, frequently with a surviving outbuilding, and with room to site a building properly rather than squeezing it.

Mature trees and their root systems, whether any review area applies, and equipment access past a large house to a deep rear garden.

An accessory dwelling unit is a second, self-contained living space on the same lot as your main house. It has its own entrance, kitchen or kitchenette, bathroom, and sleeping area. It can be detached (a backyard cottage), attached (an addition with a private entrance), or a conversion of existing space like a garage or basement.

That depends on your municipality, your lot size and your zoning district — and it genuinely varies across Cincinnati, Northern Kentucky and Southeast Indiana. We start every ADU project by confirming what your specific lot allows, before you spend anything on design.

Most of our clients are thinking about aging parents, adult children, long-term guests, a private home office or studio, or rental income. Whether short- or long-term rental is permitted is a local rules question we'll check alongside the zoning review.

Usually, yes — you already have a foundation, walls and a roof. The work shifts to insulation, moisture control, utilities, egress and finishes. We'll price both approaches if your lot supports either, so you can compare real numbers rather than guesses.

Longer than a kitchen or bath — you're adding permitting and, for detached builds, foundation and framing. The honest answer is that it depends on your scope and your municipality's review times. We give you a realistic written schedule once zoning and design are settled, and we stage all materials before starting so the build itself runs tight.

It varies more than any other project we do, because the two routes aren't really comparable. A converted garage or basement uses a shell that already stands, so the work is insulation, moisture control, utilities, egress and finishes. A detached cottage is a small house built from the ground up — foundation, framing, roof and siding, a full kitchen and bath, and services run out from the main house — so it is priced closer to ground-up construction than to a remodel. That is worth knowing before you settle on a design. Once we've seen your lot and agreed the scope you get one itemized, fixed-price contract covering everything, and our financing page sets out the options — a detached build is financed differently from a remodel.

Both. Our in-house designer plans the layout and finishes with 3D renderings, and our own crews handle the build through final walkthrough — under one contract, with one project manager.

It adds real, permitted, livable square footage and a use case most homes don't have, which buyers notice. As with any addition, quality of workmanship is what protects that value over time — which is why ours is backed for life.
