In-Law Suite Additions
Multi-generational living additions — bedroom, full bathroom, optional kitchenette, separate HVAC zone, and (where allowed) private entry. Built for parents, adult children, or live-in caretakers in Bergen County.
Multi-Generational Living Additions
In-law suites and accessory dwelling units are growing in Bergen County as families consolidate housing across generations. We design suites with the right balance of independence (private entry, kitchenette, dedicated HVAC) and connection (interior access, shared utilities). Town rules vary on whether full kitchens are allowed in additions vs accessory dwelling units.
- Bedroom with closet and full bathroom
- Optional kitchenette with cabinetry and appliances
- Separate HVAC zone or mini-split
- Private entry where allowed by town zoning
- Accessibility-focused fixtures and clearances
- Quiet construction (sound separation from main house)
Serving Bergen County homeowners across Englewood, Tenafly, Fort Lee, Ridgewood, Paramus, Teaneck, Hackensack, Closter, Fair Lawn, and Bergenfield — plus every town in between.
