Do you need a permit to rebuild a chimney in Chicago?

What the city's Express Permit terms say about chimneys

The City of Chicago launched its Express Permit Program in November 2023 as a web-based system where owners and contractors apply, pay fees and see inspection results online. The masonry terms and conditions, effective November 6, 2023, say the permit authorizes reconstruction or in-kind replacement of masonry elements other than exterior walls, and they name chimneys as an example.

The key words are in-kind and described. The rebuild has to replace what was there with the same kind of masonry, and it has to be written into the application. Work that is not described on the permit is not covered, and new masonry structures are not eligible for the express route at all.

The city's masonry instructions also say the application needs at least one photo of the existing condition, the property's PIN and the owner's information. A clear photo of the chimney before work starts is part of the process, not an extra.

When no permit is needed

The city's permit-not-required page for masonry says that in a residential building up to four stories, removing and replacing up to 50 square feet of masonry in kind needs no permit. In kind means the same type, size and shape of material.

On a chimney, 50 square feet covers a lot of spot work: replacing a few spalled bricks, resetting a loose top course, or rebuilding a small section of a crown area with matching brick. A full rebuild from the roofline up on a typical bungalow or two-flat stack can pass that line, which is where the Express Permit comes in.

• The exception may not apply to proposed or designated Chicago Landmarks or landmark districts.
• Work done without a permit must still meet the Chicago Construction Codes, according to the same city page.
• Masonry cutting, grinding and cleaning must follow dust-control rules, and some jobs may need an air quality permit from the Chicago Department of Public Health.

Chicago's codes are not the suburbs' codes

Chicago writes its own construction codes. Its Building Code is based on the 2018 International Building Code, and the city's code list does not include the International Residential Code that many suburbs use. The Express Permit terms point masonry work to Chapter 21 of the Chicago Building Code.

For homeowners, that means a chimney rebuilt in the city and one rebuilt in a suburb can be held to different rules. We build to current code for the town the house sits in, and we do not guess at a suburb's permit rules. Before any work starts, we check what your city requires and tell you what we found.

What a rebuild usually costs

Price depends on how far down the damage goes. Rebuilding the top few feet with a new crown usually runs $600 to $1,000. Rebuilding everything above the roofline runs $1,000 to $3,500. Replacing the whole chimney runs $4,000 to $15,000. These are typical 2026 ranges, and we confirm yours with a written price after the free inspection.

Many Chicago chimneys were built from Chicago common brick, which has not been made since 1981. When a rebuild should match, we look for salvaged commons of the right color so the new top looks like it belongs to the house.

How we plan a rebuild with the permit in mind

At the free inspection we photograph the chimney, measure how much brick is failing, and note whether the house sits in a landmark district. You get a written scope that says exactly what will be rebuilt and with what materials, which is the same description the city wants to see on an Express Permit application.
