Basement Apartment / In-Law Suite · Clifton, NJ
Finish or convert a basement into a rentable apartment or accessible in‑law suite. We handle plans, permits, and interior build‑out for Clifton homes.
We convert basements into self-contained apartments or in‑law suites with code-compliant egress, insulation, partitions, bathrooms, kitchens, mechanical routing, and interior finishes. Work is limited to interior remodeling and any exterior work only if required for an addition or egress and permitted through Passaic County.
