Basement Apartment / In-Law Suite · Chatham, NJ
Convert underused basements into independent living spaces designed for safety, code compliance, and long-term livability. We focus on practical layouts and reliable finishes.
We build permitted basement apartments and in-law suites in Chatham, NJ, handling framing, insulation, egress, drywall, flooring, kitchens, bathrooms, and HVAC coordination with trades. Work starts with a site walkthrough to verify ceiling height, access, and egress needs so the plan meets Morris County and state codes.
Our work
FAQ
Costs vary by scope, size, and code upgrades. Typical interior-only builds start with a site walkthrough; after assessing ceiling height, egress, and utilities we provide a written estimate with options for finishes.
Small finishes can take 6–8 weeks; full builds with structural or egress work often take 10–16 weeks including permit and inspection time. Exact timeline is given in the estimate.
There is noise, dust, and temporary access changes during demolition and rough-in. We schedule work in phases, protect living areas, and keep a clear daily window for noisy trades where possible.
Schedule an on-site walkthrough. We document existing conditions, discuss layouts and code needs, then deliver a written proposal and timeline to move forward.
