Reunion is one basement. The south side is another.
Saw Dog Construction finishes basements in Commerce City, CO, from newer areas like Reunion to older homes on the south side. Our team designs the layout, files the permit with the City of Commerce City, builds the rooms, and stays through inspection. The work carries our 2-year workmanship warranty, and our permitted basement work here is already in the public record.
Reunion, Buffalo Run, Turnberry, Second Creek Farm and Fronterra Village are full of newer houses with the basement still open. The usual ask is a straight finish, plus an egress window when a bedroom is going downstairs. Building codes generally require a basement sleeping room to have an emergency escape and rescue opening. We cut the egress window, set the well, and put it on the same City of Commerce City permit as the rest of the finish.
South Commerce City is older stock. Neighborhoods such as River Run call for a more careful finish in a house that has already been lived in. Same company, same inspections, same 2-year workmanship warranty. The city overview, including the permit record, is on our Commerce City page. If the bedroom is the whole question, the Reunion write-up is Turning a Reunion Basement Room Into a Real Bedroom.
Commerce City sits in Adams County and issues its own building permits through the City of Commerce City. Our permitted, inspected basement work here is in the public record. On your project, our team files the permit, builds the space, and stays through the city's sign-off. We call the job done when that inspection is behind us.
