Reading the Evanston data for plumbing

Evanston is one of the most established suburbs tracked here — 76,380 people (2025 estimate), down just 2.2% since 2020^[2]. On the map that's 7.8 square miles holding 9,819 residents per square mile, the 1st densest of the suburbs here; it sits entirely in Cook County, with ZIP codes 60201, 60202, 60208^[3].

With 8% of homes built since 2010 and 76% before 1980^[1], Evanston's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.

Evanston is split across 3 ZIP codes: 60201 (58% of the city's land), 60202 (39% of the city's land), 60208 (3% of the city's land)^[6].

Nearest of the other suburbs we track: Skokie (2.5 mi W), Des Plaines (10.6 mi W) and Arlington Heights (15.2 mi W)^[3].

76% of Evanston's 34,095 housing units predate 1980 and 8% went up in 2010 or later^[1] — the 2nd-highest pre-1980 share of the 15 Chicago-area suburbs we cover; nearby, Skokie (85%), Des Plaines (71%), and Arlington Heights (64%) predate 1980. Houses that old can still have galvanized supply pipe or cast-iron drains — especially the 59% built before 1960.

The biggest single slice — 40% — was built 1939 or earlier, and the median home dates to 1953^[1]. Neighbours from the same era tend to hit the same plumbing problems at the same time.

Freeze risk: the cook forecast zone logged 20 winter-storm, ice or hard-freeze days in 2016–2025; the latest was Dec 4, 2024^[4].

Water from the sky is plumbing work too: 56 flood or flash-flood reports within 10 miles over 2016–2025^[4], and FEMA logged 25 flood-insurance claims across Evanston's ZIPs^[5]. Homes that take water need working drainage, sump pumps and backflow prevention.

75% of homes heat with utility gas, and 44% of households rent^[1]. Tenants: report plumbing failures to the landlord in writing.

Among the 15 suburbs tracked here, Evanston stands out for the oldest housing (by median year built) (1953)^[1], the lowest gas-heat share (75%)^[1], the highest renter share (44%)^[1], and the 2nd-highest pre-1980 housing share (76%)^[1].
