Decimal-Acre Reference / Sheet 0.07
0.07 Acres = 3,049 sq ft
Seven hundredths of an acre, the historic Craftsman-bungalow lot. The dominant parcel in Atlanta's Inman Park, the Chicago Bungalow Belt, and Berkeley's Northbrae. The math is exact: 0.07 multiplied by 43,560 equals 3,049.2 square feet.

Why this lot built American suburban housing
0.07 acres is the size that defined the American suburban housing pattern from roughly 1905 to 1940. The Craftsman bungalow movement, which produced more new American houses than any other architectural style of the early 20th century, was designed around a 30-foot-wide by 100-foot-deep lot. That lot dimension equals 3,000 sq ft, or 0.069 acres, which rounds to 0.07 on a tax record. Sears Roebuck sold over 70,000 mail-order houses between 1908 and 1940, and the catalogue's standard floor plans were built around fitting on this lot size. Aladdin, Lewis, and the Gordon-Van Tine Company (the other major mail-order house companies of the era) used the same lot-dimension assumption.
The Chicago Bungalow Belt is the largest concentrated example. From 1910 to 1940, Chicago developers platted roughly 80,000 brick bungalows on 30-by-125-foot lots (3,750 sq ft, 0.086 acres). The slightly deeper Chicago lot allowed for a detached garage on the alley, but the same 30-foot-wide front-of-house pattern. The Pittsburgh Mexican-War Streets neighbourhood, the Detroit Boston-Edison historic district, and the Los Angeles West Adams Heights area all use variations on the 0.07-acre lot.
The bungalow-lot dimension matters today because of historic-district preservation. Atlanta's Inman Park, designated a historic district in 1973, requires that any new construction or renovation maintain the original lot configuration. This locks in the 0.07-acre parcel as the dominant size in the neighbourhood and prevents subdivision into smaller townhouse lots. Similar preservation overlays apply in Berkeley's Northbrae (designated 2002), Chicago's Norwood Park (2014), and Charleston's North Central (2019). A 0.07-acre lot in any of these districts is essentially a permanent parcel.
For new construction outside the historic districts, the 0.07-acre lot remains attractive to builders because it is large enough to accommodate the contemporary small-lot bungalow plan (typically 1,400 to 1,800 sq ft of livable area on a 1,000 sq ft footprint with a one-car garage at 240 sq ft) but small enough to keep land cost manageable. The Atlanta Infill Lots programme run by the city land bank releases roughly 200 lots per year in the 0.05 to 0.10 acre range, with the 0.07-acre tier being the most common.
