Ridgewood home additions

Ridgewood is built almost entirely of attached row houses and small multifamily buildings from the early 1900s, set on narrow lots with shared party walls. That layout shapes every addition decision here. You rarely have a side yard to expand into, so the practical moves are a rear extension into the back yard, a second-story or roof addition over the existing footprint, or a modest bump-out off the kitchen. Party walls also mean we coordinate closely with the structure you share with neighbors, both for support and for fire separation.

The zoning math matters more in Ridgewood than the available land. Most of the neighborhood sits in lower-density residential districts where FAR, required rear-yard setbacks, and lot coverage limits cap how much you can add before you trip into a variance or a special permit. A rear extension usually has to hold a minimum rear-yard depth, and a second story has to stay under the allowed floor area and height. We run those numbers against your block's zoning before any design work so you know up front whether a full extension, a partial bump-out, or an ADU is realistic for your lot.

Approvals are their own process. Work that changes the building envelope needs DOB filings, and on Ridgewood's landmark blocks any visible exterior change also needs LPC sign-off, which affects materials, window styles, and how an addition reads from the street. We handle the filing path, the structural drawings, and the inspections so the addition is permitted, legal, and built to hold a second floor's load on a hundred-year-old foundation.
