Apartment archetypes in Chicagoland
Courtyard buildings and stacked flats share turnover discipline with Northeast pre-war stock — measure every opening, pick mount type from depth, standardize white vinyl mini on bedrooms.
- Three-flats and six-flats — stacked units with double-hung bedrooms and shared rear courts
- Courtyard walk-ups — light wells and narrow bedroom bands
- Post-war garden-style wings on older campuses
- Patio sliders on ground-floor units — 68" × 84" and 78" × 84" vertical pairs
- Brick and limestone returns — confirm depth before inside-mount faux wood
Field guides for Chicago
Each guide covers mounting depth, typical opening sizes, and reorder specs for a specific housing archetype — not a generic city landing page.
Window Field Guide · Chicago Flats & Courtyard Buildings
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.

Post-war masonry walk-ups: brick returns, steel lintels, and reorder specs
Post-war masonry walk-ups and elevator buildings from the 1950s through the 1970s sit between pre-war plaster stock and Sun Belt garden-style — brick or limestone facades, steel lintels, double-hung bedrooms, and patio sliders on newer wings. Outer-borough NYC, Chicago post-war courts, DC 1960s flats, and Boston garden-style masonry blocks share turnover discipline: measure every opening, standardize white vinyl mini on bedrooms, vertical on sliders.

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.

Rust Belt walk-ups and doubles: brick jambs, party walls, and turnover specs
Detroit, Cleveland, Buffalo, and Pittsburgh carry dense brick walk-up and double-house rental stock — two-family flats, four-unit blocks, and mill-adjacent row conversions with shallow returns, uneven double-hungs, and rear additions with slider modules. This stock is not Chicago courtyard flats and not Northeast pre-war plaster — landlords standardize on white vinyl mini in bedrooms and vertical on rear sliders.

Garden-style apartment windows: what property managers actually reorder
Garden-style and walk-up apartments built from the 1960s through the 1990s dominate Sun Belt turnover stock — two or three stories, exterior stairs, surface parking, and a sliding patio door on almost every unit. Unlike pre-war Northeast walk-ups, these openings are usually vinyl or aluminum double-hungs in bedrooms and a rear slider in the living area — shallow but predictable once you measure. Property managers from Arlington to Houston, Atlanta, Phoenix, Tampa, and Orlando standardize on 1" white cordless vinyl mini in bedrooms and 3.5" vertical on patio sliders. This guide maps mount methods by material — not a generic apartment marketing page.

Patio sliders and sliding glass doors: pick product, size, and stack side first
A patio slider is a product problem before it is a city problem — the same 72" × 80" rear door appears on Houston production homes, DFW ranch plans, Florida lanais, garden apartments, and Phoenix block/stucco stock. Buyers search by opening size (68×84, 78×84, 72×80, 94" wide) and by product type (vertical vs roller vs faux wood panels). This guide maps the decision tree: measure glass, pick vertical or roller or stacked faux, choose stack side, then pick inside vs face mount on the header.
