Basement Apartment / In-Law Suite · Cranford, NJ
Design and build finished basement apartments and in-law suites for Cranford homes. We focus on practical layouts, code compliance, and clear pricing.
We convert underused basements into rental units or accessible in-law suites with sleeping, bathing, kitchenette, egress, and separate entries where possible. Work begins with a site walkthrough to confirm ceiling height, waterproofing needs, existing mechanicals, and exit routes so we can plan to meet Union County codes.

FAQ
Costs vary by size, existing conditions, and finishes. Typical interior-only conversions start with a walkthrough and written estimate so you get line-item pricing for labor and materials.
Small conversions often take 6–8 weeks after permits; full one-bedroom builds usually run 8–14 weeks. Timeline depends on permit turnaround and scope of mechanical upgrades.
Yes. Most basement conversions allow homeowners to stay in the house. We schedule noisy or dusty work in phases, isolate the work area, and keep shared utilities operational when possible.
Request a walkthrough — we’ll inspect the basement, discuss layouts and code issues, and provide a written estimate. The in-home consult is the usual first step to move forward.
