Basement In-Law Suite in Columbus, OH
Columbus Basement Finishing connects Columbus homeowners with local contractors who build basement in-law suites: a bedroom with an egress window, a bathroom, a sitting area and a kitchenette. It is the largest kind of basement project because it combines all of them. Renting the space out is a separate matter with its own zoning and code rules.

What an in-law suite includes
An in-law suite is a small home within the house. A complete one has:
- A bedroom with an egress window.
- A bathroom, ideally with a walk-in shower.
- A sitting area.
- A kitchenette.
- Its own heating and cooling control, so the occupant sets the temperature.
It is the most involved basement project, because it combines the most plumbing, the most electrical work and a structural opening for the window.
Designing for an older relative
If the suite is for a parent, plan for mobility now, even if it is not needed yet:
- Access. Stairs are the obstacle. A walkout basement with a level entrance is ideal. Otherwise, add sturdy handrails on both sides of the stairs and good lighting.
- Doorways wide enough for a walker.
- A curbless shower with a bench and blocking in the walls for grab bars.
- Lever handles on doors and faucets.
- Flooring that is level, firm and not slippery.
- Light switches and outlets at easy heights.
Privacy and sound
The suite should feel separate. Insulate the ceiling to soften footsteps from above, use solid doors, and if possible give the suite its own entrance from the stair landing, so nobody walks through it to reach the laundry or storage.
Family use and renting are different things
Housing a relative is generally straightforward. Renting the space to a tenant is not. A rental unit normally has to satisfy zoning rules about second dwellings, and may need separate exits, fire separation and its own utilities. Check with your city's zoning office before you design the space as a rental.
Budgeting
Expect an in-law suite to cost well above a basic basement finish. The estimate will break out the bathroom, kitchenette and egress window so you can see where the money goes.

Basement In-Law Suite FAQs
Can I rent out a basement suite?
Possibly, but a rental unit usually has to meet zoning rules and extra code requirements that a family suite does not. Ask your city's zoning office before designing for rent.
Does an in-law suite need its own entrance?
Not for family use. A walkout basement makes one easy, and it helps older relatives avoid the stairs. Adding an exterior door to a fully below-grade basement is a major job.
