Basement Apartment / In-Law Suite · Union, NJ
Interior remodeling and legal finishing for rental or family use. We handle layouts, egress, finishes, and coordination with local code requirements.
We convert unfinished basements into self-contained living units or attached in‑law suites: framing, insulation, drywall, new kitchens, bathrooms with proper ventilation, electrical upgrades, heating distribution, flooring, interior doors and trim, and built-in storage. Work focuses on code-compliant egress, moisture control, and noise separation.

FAQ
Costs vary by size, finish level, and existing conditions; expect a wide range depending on whether structural work, new stairs, or full MEP upgrades are needed. We provide a walkthrough and a written estimate listing options so you can compare line items.
A straightforward interior finish often takes 8–12 weeks after permits; projects needing structural changes or extensive utility work can take longer. Permit lead times in Union County affect the schedule; we review timing at the initial walkthrough.
Many homeowners remain in the house while we work, but expect staged access, noise, dust containment, and periodic shutdowns of circuits or water to the work area. We outline daily access rules and cleanup in the project plan.
Request a consultation and walkthrough so we can evaluate your basement, discuss egress and code issues, and prepare a detailed estimate and timeline.
