Renovating a Chicago worker's cottage

Worker's cottages are among the oldest homes in many Chicago neighborhoods. They are small, which makes every layout decision count, and their age means past repairs are often layered on top of each other.

What it is

The worker's cottage is a vernacular Chicago house type built from the 1870s to the 1910s for working- and middle-class owners: a gable-front house, usually one and a half stories, with a narrow footprint sized for 25-foot city lots.

On a standard lot a cottage usually measures about 20 feet wide and 30 to 60 feet long. Cottages were built of wood or brick; after the 1871 fire, brick was required within a zone roughly matching the city limits of that time.

By the 1871 fire, frame cottages had become Chicago's dominant urban house form. Their plan typically put bedrooms down one side and the parlor, dining room and kitchen down the other.

Renovating one today

Wood cottages were balloon-framed, sturdy enough that in the 1890s owners often lifted the whole house to add a floor underneath. Different materials on the lower and upper floors can be a clue that a cottage was raised.

NHS notes that raised cottages can sit 6 to 12 feet above grade, which eases basement windows and entries. Existing basement terraces, common in Pilsen, may mark street level before streets were raised and signal that an ejector pump will be needed.

Original clapboard on frame cottages is often hidden under later layers, including asbestos shingles or asphalt sheets from the 1930s to 1950s, artificial stone such as Perma-Stone, and vinyl or aluminum siding from the 1960s to 1990s.

Chicago's Old Town Triangle District, one of ten landmark districts the city designated in the 1970s, is made up largely of worker's cottages.

In Chicago landmark districts, permit applications are checked for effects on significant features, usually the exterior walls visible from the street. Routine upkeep such as painting and minor repairs needs no permit.

How we approach it

We expect to find older framing, wiring and plumbing once walls are open, and we price discovered work as change orders you approve before it is done.

In a small house, sequencing matters. We plan the work so the parts of the house you need stay usable for as long as possible.
