Basement Apartment / In-Law Suite · New Brunswick, NJ
Interior remodeling for legal basement apartments and in-law suites. Practical plans, clear estimates, work staged for occupied homes.
We convert basements into self-contained living units: sleeping area, kitchen or kitchenette, bathroom, egress-compliant windows, sound separation, and dedicated mechanical/access spaces. For homeowners in Middlesex County we handle layout, insulation, drywall, flooring, interior carpentry, cabinetry, tile, interior painting, and lighting coordination.

FAQ
Costs vary by size, finishes, and code work. Typical interior-conversion budgets depend on egress, plumbing reroutes, and finish level. We offer a site walkthrough and written estimate to give an accurate cost for your specific basement.
Most projects run 8–14 weeks after permitting depending on scope and inspections. Timelines shorten if the scope avoids major plumbing or structural changes; we confirm schedule during the estimate walkthrough.
Yes—most clients remain in the home. Work is staged to isolate dust and noise, and we protect common areas. We review day-to-day access and disruption during the pre-construction walkthrough.
Request a site visit: we perform a walkthrough, confirm code/egress needs, and provide a written estimate. Contact us to schedule the consultation and get a scope tailored to your basement.
