Basement Apartment / In-Law Suite · Metuchen, NJ
Design and build a safe, code-compliant basement apartment or in-law suite that fits your budget and property. We handle layout, egress, insulation, finishes, and municipal filings.
We convert basements into self-contained living spaces for long-term guests or rental income. Work begins with a walkthrough to assess ceiling height, egress options, moisture control, and mechanical routing. Typical scope covers framing, insulation, drywall, electrical circuits, plumbing rough-in for a kitchenette and bathroom, ventilation, fire separation, flooring, lighting, and lockable entry.

FAQ
Costs vary with size, egress work, plumbing relocation, and finishes. Expect higher costs when adding full bathroom or separate HVAC. We provide a no-surprise written estimate after an on-site walkthrough and scope review.
Typical projects run from 6 to 12 weeks after permits, depending on complexity and inspection scheduling. We give a project timeline with the estimate and update it at key milestones.
Yes. Basements converted to independent living units require local permits, inspections for egress, plumbing, electrical, and fire separation. We prepare permit drawings and submit them on your behalf.
Often yes, but expect intermittent noise, dust, and restricted access to parts of the home. We plan phasing to minimize disruption and protect occupied areas; we review living-arrangement impacts during the walkthrough.
Schedule an on-site consultation and walkthrough. We inspect the basement, discuss scope and priorities, then deliver a written estimate and timeline.
