Create Rental Income with Egress Windows & Full Plumbing
A basement apartment requires specific features to ensure safety, comfort, and compliance with building codes. Egress windows are essential, providing natural light, ventilation, and a safe emergency exit. The International Residential Code, adopted by Pennsylvania, mandates that egress windows have a minimum opening of 5.7 square feet, with at least 20 inches in width and 24 inches in height, and be no higher than 44 inches from the floor.
At BiiLT Group, we expertly install egress windows to meet these standards, enhancing both safety and aesthetics. Additionally, a basement apartment needs comprehensive plumbing and electrical systems to function as a self-contained living space. This includes installing bathrooms, kitchens, and wiring for lighting and appliances. Our team manages all plumbing and electrical installations, ensuring they adhere to local codes and perform reliably.
Investing in a basement apartment can generate consistent rental income, helping to offset mortgage costs or build savings. It also increases your property’s market value, making it a strategic choice for long-term financial growth. With BiiLT Group’s expertise, your basement becomes a functional and profitable asset.

All of the people are extremely nice and good workers. I have 4 dogs at my house during the day and they are excellent with making sure the gate is closed and the dogs are safe. This time we got new hardwood floors, they replaced our bathtub and retiled the shower, built a new bathroom in the basement and replaced our deck and screened it in. We are very happy with all the work. They always make sure we are happy with everything before they close the job. Shoutout to the guys that did the work this time.
