Basement in-law apartment ideas

Transforming an unfinished basement into an apartment or suite definitely qualifies as a major home makeover. When choosing to work with Total Basement Finishing of Western NY, you can be confident that all code and safety requirements will be met in this new space along with friendly, attentive service. You’ll also benefit from our expert design consultation that will help you customize your basement apartment to suit the needs of in-laws or other residents. Here are a few design ideas for an in-law apartment:


Larger windows are a great addition because of the additional natural light they provide.

Bigger windows

In most areas, the local building code will require any basement bedroom to have a safe, direct means of egress to the outside.

In a walkout basement, egress can be provided by a door.

Otherwise, a standard basement window opening can be enlarged to install a larger egress-compliant window.

Barrier Free Bathroom

Barrier-free bathroom

Older people and individuals with disabilities often require special features in a bathroom, such as grab bars and curbless shower stalls.

Fortunately, a wide range of bathroom fixtures are available for differently abled folks.

It’s less expensive to incorporate these fixtures during new bathroom construction than to retrofit them at a later date.


Adding a doorway helps to isolate basement noise and provide privacy.

Enclosed interior stairway

Privacy and soundproofing are important when you create a basement apartment.

That’s why you might want to enclose the bottom of the basement’s interior stairway.

This treatment creates an entry vestibule at the base of the stairs –an extra layer of separation between the apartment and the house.

A SaniDry™ dehumidifier will keep your basement dry and mold-free

Temperature & humidity control

No matter who is living in your basement apartment, you'll want them to be comfortable. An economical way to provide heat in a basement apartment is to install electric baseboard units that can be controlled by a thermostat. But to hold that heat in and reduce your heating costs, you'll need to insulate your basement's foundation walls with rigid foam insulation.

The best way to keep humidity levels in check is to rely on a SaniDry® dehumidifier from Basement Systems. This ENERGY STAR® dehumidifier is designed to automatically maintain the humidity level you select, while also removing dust and other particulate irritants from basement air.
