Basement Apartment / In-Law Suite · Princeton, NJ
Convert your basement into a rental unit or in-law suite with proper egress, utilities, and code compliance.
Princeton homes often have foundation space suited for basement conversion, but the work requires navigating local setback rules, ceiling height codes, and egress window requirements. We handle structural assessment, plumbing and electrical routing, ventilation, and final inspections to meet Mercer County standards.
