Gutter installation for cottages and bungalows in Hermosa, Chicago

Scottish settlers called the area Kelvyn Grove in the 1870s and 1880s, the Garfield subdivision of 1882 sold Keeney cottage houses to 150 buyers, annexation followed in 1889, and slow nineteenth-century growth in worker's cottages gave way to the 1920s boom: Kelvyn Park brick bungalows and two-flats, and southern Hermosa brick bungalows, two- and three-flats, and small apartment buildings of five or more units, nearly completely built out by the end of the 1920s. A 2012 figure put the median home age at 1919, with about 63 percent built before 1940. Pitched cottage and bungalow roofs mix with flat two- and three-flat roofs, and homes of this era typically split by form, with tight 25-foot frontages constraining side-yard routing, so gutter repair is planned per lot width.

Worker's cottages carry small pitched roofs with wood fascia and short runs, while the 1925-1929 bungalow peak concentrated single-era detailing across whole blocks, with 1927 the peak year. Shared downspouts serve two- and three-flats, rear and alley discharge dominates, and rail-embankment grading is noted as an inference, unverified. Downspout placement on a 25-foot lot leaves little room for error, and rear discharge routes are checked lot by lot.

The Hermosa Bungalow Historic District was listed on the National Register on 31 December 2018, covering about 323 contributing buildings including 298 brick bungalows from 1925 to 1929, near Belmont, Lowell, Diversey, and Kolmar, with no Chicago Landmark designation. Kelvyn Park and Hermosa Park split at Fullerton, and the Hermosa Improvement Association of 1912 gave Hermosa Park its start. Check the designation details for the specific address before work.
