Start with how the new household will use the Durham property. For the Durham property, these three paths create different kinds of independence and different construction questions.
Detached Homes With Their Own Front Door
A detached ADU gives a Durham household its own building, kitchen and entrance. For the Durham property, ask a contractor to place it on a site sketch with the main house and the route between them.
For a Durham household, the building price should account for its foundation and the connections back to existing services. On the Durham estimate, make room for excavation, ground restoration and any system changes the proposal requires.
Garage Apartments That Preserve Yard Space
A garage apartment may keep more of a Durham yard available for daily use. For the Durham property, the important distinction is between building a new structure for living space and adapting a garage designed only for vehicles.
For a Durham household, have the existing foundation and framing checked before assuming they can carry another floor. A Durham garage proposal also needs a usable stair arrangement, appropriate fire separation and a clear answer about the parking it changes.
In-Law Apartments Close to the Main Household
An in-law apartment can use part of the Durham house or a new attached wing. For the Durham property, a separate entrance and thoughtful sound control help relatives keep their own routines.
For a Durham household, the lowest apparent cost is not always the most useful option. In a Durham basement, ceiling height, moisture and a safe escape route can matter more than the amount of unfinished floor space.
What ADU Services Do We Offer in Durham?
We introduce Durham homeowners to independent contractors for these three project paths.
- Detached ADU planning and construction estimates
- Garage apartments and structural conversion reviews
- In-law apartments within or attached to the Durham house
For a Durham household, a detached cottage and an apartment within the house can use the same lot very differently. For the Durham property, compare the daily entrance route and the utility work before deciding which option suits the family.
