Basement Apartment / In-Law Suite · Mount Olive, NJ
Design and build an accessible, code-compliant lower-level apartment or in-law suite tailored to your property and budget. We handle plans, permits, and interior finishes.
We convert basements into self-contained apartments or in-law suites that meet local codes and livability needs. Projects include insulated walls, egress, separate entry where possible, kitchens, bathrooms, lighting, HVAC planning, and fire-safety measures. We coordinate drawings, subcontractors, and permit submissions so you get one point of contact through construction.

FAQ
Costs vary by size, existing conditions, and scope. Typical factors are structural work, new egress, full bathroom and kitchen, and HVAC. We provide a written estimate after a site walk to review conditions and layout options.
From design to finish most interior conversions take 8–16 weeks depending on permitting, scope, and inspection scheduling. We’ll give a timeline with the estimate and update it after permits are filed.
Most basement apartments require building permits and inspections for egress, electrical, plumbing, and mechanical work. We prepare permit-ready plans and submit them on your behalf or coordinate with your architect.

Request an on-site consultation and scope walk. We’ll inspect the basement, discuss layouts and budget priorities, and provide a written estimate and proposed timeline.
