FAQ
Costs vary by size, finish level, and MEP work. Typical budgets start where framing, insulation, bathroom, kitchenettes, and code upgrades are included. We provide a written estimate after a walkthrough to itemize costs for your specific space.
A standard finish runs from 8 to 14 weeks after permits are approved. Timelines shift if structural work, sewer/drain changes, or complex MEP work is required. We include a projected schedule in the estimate.
Yes. Basement apartments require local permits, egress compliance, and inspections in Essex County. We prepare permit drawings or coordinate with your architect and submit applications on your behalf.
Most homeowners stay in the house, but expect noise, dust containment, and periodic utility interruptions. We set up protection zones and a work schedule to limit daily disruption.
Request a consultation and on-site walkthrough. We measure, review egress and mechanical needs, then deliver a detailed estimate and timeline.
