Basement Remodel questions, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

You technically can paint wires in a basement ceiling, but there are several important safety and code considerations. It's safe to paint non-metallic sheathed cable as long as the labeling remains visible. You can also paint low-voltage wires and conduit and junction boxes to help them blend into your basement. 

However, you should not paint damaged or deteriorated wiring is a fire hazard because it poses a fire hazard. The same goes for painting over high-heat wires that connect to heat-generating appliances or systems. Be sure to avoid painting multiple coats onto any wires, as that traps heat and poses fire risks.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.
