Homes in Mahwah
Mahwah's housing is newer than most of Bergen County's and includes many townhouses. Of about 10,300 housing units, 47% are single-family detached and 20% are single-family attached (townhouse-style) (ACS 2020-2024, B25024). The median building dates to 1984, and 52% of units were built between 1980 and 1999 (B25035, B25034). About 81% of occupied homes are owner-occupied, and utility gas heats 86% of them (B25003, B25040).
Many townhouse communities have homeowners associations, so check your association's rules before hiring for exterior work such as roofing, siding or decks. Homes from the 1980s and 1990s are now at the age when original roofs, water heaters and HVAC systems are commonly replaced. Permits come from the township's Construction Office, which posts a construction permit chart and forms.
Flooding
Mahwah has riverine flood risk along the Ramapo River, which has a flood stage of 8.0 feet at the Mahwah gauge. The county hazard mitigation plan records flooding there in April 2007 and a March 2010 nor'easter that hit Mahwah and Upper Saddle River. The plan puts 5.82% of the township's land in the 1% annual-chance floodplain and 0.96% in the 0.2% floodplain. It lists 159 active NFIP policies as of October 2024 (Bergen County HMP). The county plan also lists a Mahwah River shoal removal project (Community Profile). To check a specific address, use the FEMA Flood Map Service Center.
