For homeowners on roomier lots. R4-1 allows small one- and two-family houses, often semi-detached (sharing one wall with a neighbor). Buildings stay low — up to 35 feet, about 2 stories. FAR (floor-area ratio, the cap on total floor space relative to lot size) is 0.9, so a 2,000 sq ft lot gets roughly 1,800 sq ft of building. Low-key, leafy outer-borough blocks.
