Window Field Guide · Pre-War & Post-War Apartments
Pre-war apartment windows: mount depth, materials, and what landlords reorder
Pre-war and early post-war apartments rarely share one window module. Jambs are shallow, plaster is uneven, and patio sliders want a different treatment than narrow bedroom openings. This guide maps mounting methods by blind type — not a generic city landing page.

Triple-decker windows: measure every floor separately
Three-family wood-frame buildings from the 1890s–1920s repeat a floorplan — but almost never repeat the same opening size after a century of settlement. Boston landlords reorder 1" vinyl mini more than any other line for turns. This guide covers mount methods by material, not a tourism page about the city.

Chicago flat and courtyard windows: measure front, gangway, and court separately
Chicago's rental stock is built around flat-type buildings — two-, three-, four-, and six-flats stacked over a shared stair hall, plus larger courtyard apartments shaped by the 1902 Tenement House Ordinance. Wood double-hungs dominate; greystone and brick facades hide uneven jambs and shallow returns. Landlords reorder 1" vinyl mini more than any other line. This guide covers mounting by material for that building type.

Twin Cities duplex and courtyard windows: match the unit, not just the building
The Twin Cities rental stock is built around missing-middle housing — Craftsman-era double bungalows, side-by-side and up/down duplexes, triplexes and fourplexes, plus 1930s brick courtyard walk-ups designed for light and cross ventilation. Wood double-hungs and Prairie-style transoms dominate; storm windows and deep sills are common. Landlords reorder 1" vinyl mini more than any other line for turns.

Seattle craftsman and courtyard windows: what landlords actually reorder
Puget Sound rental stock is Craftsman-heavy — bungalows subdivided into duplexes and fourplexes, missing-middle buildings in Wallingford and Ballard, and 1920s–30s courtyard walk-ups on Capitol Hill built for light and cross ventilation. Wood double-hungs and grouped casements dominate. Many property managers standardize on 2" white cordless faux wood for a finished look that handles damp rooms; vinyl mini still shows up on budget turns and back bedrooms.

LA courtyard and dingbat windows: what landlords and PMs actually reorder
Los Angeles rental stock layers 1920s Spanish Revival courtyard walk-ups in Hollywood and Los Feliz over a vast field of 1950s–60s dingbat stucco boxes — two-story walk-ups with tuck-under parking and a decorated street façade. Wood casements and double-hungs fill the older courts; dingbats often mix original aluminum sliders with vinyl replacement windows after decades of turns. Many property managers standardize on 2" white cordless faux wood for a finished line that handles sun and humidity; vinyl mini still covers budget turns; verticals stay on patio sliders.

Eugene craftsman fourplex and bungalow windows: what landlords actually reorder
Lane County rental stock is Craftsman-heavy — early 1900s four-plex apartment houses (including the Working brothers' clapboard fourplexes near downtown), bungalows subdivided into duplexes around Whiteaker and Jefferson Westside, and a wave of 1960s–70s walk-ups in the West University neighborhood after campus housing rules changed. Wood double-hungs and grouped casements dominate older stock; near-campus buildings often mix original wood windows with vinyl replacements after decades of student turns. Many owners standardize on 2" white cordless faux wood for durability in damp rooms; vinyl mini still covers budget turns and back bedrooms.
