What needs a permit
From the Department of Buildings' fence exemption list, express fence page and its terms (read 23 October 2026):
| Fence | Permit? | Extra documents |
|---|---|---|
| Up to 5 ft, measured on both sides, conforming to zoning | No | — |
| Painting or replacing limited damaged parts of an existing fence | No | — |
| Retaining wall up to 4 ft (footing to top), no surcharge | No | — |
| Backyard fence over 5 ft, up to 6 ft | Yes, express | None for most applications |
| Front-yard fence up to 54 in, or up to 6 ft if at least 80% open | Yes, express | None for most applications |
| Fence over 6 ft, up to 15 ft, with zoning approval | Yes, express | Official survey and a scaled site plan |
| Masonry (brick, stone or concrete) fence or wall | Yes, express | Drawings by an Illinois architect or structural engineer |
| Fence that breaks zoning, or over 15 ft | Not eligible | — |
| Fence built without a required permit | Express permit can "legalize" it in many cases | — |
The exemptions "may not apply" to a Chicago Landmark or a landmark district. A structure on the street, alley, sidewalk or parkway (the "public way") "generally requires a separate public way use permit" from the Department of Business Affairs and Consumer Protection.
The height rules that fail inspections
The terms measure height "from the lowest surface within 12 inches horizontally on either side of the fence to the highest point of the fence, excluding fence posts". Posts may run 6 inches over. On a sloped lot that means the low side counts. A fence that does not match its permitted height at inspection "must be rebuilt to be consistent with the permit at the contractor or owner's expense". Zoning sets the ceiling: residential fences are generally limited to 6 feet, and fences in the required front setback to 54 inches if more than 20% solid. The permit "does not allow installation of an electrified fence or any other electrical work", and barbed or razor wire is allowed only if described on the application and no lower than 7 feet.
Who can pull it, and the fee
The express fence permit needs a licensed general contractor (Class A to E) or the owner acting as general contractor on a primary residence with no more than 6 units and no building over 3 stories, one property per calendar year (GC license page), with Form 401 and ID showing you live there. A masonry fence adds a licensed mason contractor, Class A or B. Check either on Licensed Trade Contractors.
Fees are set by section 14A-12-1204.2 (stand-alone permit fees), with the 2026 Amended tables (effective 6 January 2026) linked from Calculate the Cost of a Building Permit. We could not open the tables, so we quote no amount; the express application shows the fee before payment.

What this does not tell you
Exempt fences up to 5 feet leave no permit, so our figures describe taller and front-yard fences. Chicago's permit file has no completion date, so days to completion is estimated from status and age. We do not match Chicago firms to the City's license list.
How we know this
Exemptions, express eligibility, height rules and contractor requirements are quoted from the City of Chicago Department of Buildings' fence exemption, Express Permit Program fence and fence terms pages and its general contractor page, and fee references from its Calculate the Cost of a Building Permit page, all read 23 October 2026. Counts are City of Chicago Fence or Trash Enclosure express permits on homes, October 2023 to September 2026. "Marked complete" uses permits a year or more old; usual days is an estimate because Chicago records no completion date.
Numbers come from City of Chicago building permits (Chicago Data Portal), data through October 17, 2026. Nobody paid to be on this page and nobody can.

Six feet on the express permit. The City's terms say residential fences are 'in general' limited to 6 feet, posts may exceed the permitted height by up to 6 inches, and a fence up to 15 feet needs zoning approval.

54 inches (4.5 feet) if it is more than 20% solid, or up to 6 feet if it is at least 80% open, such as wrought iron, under the express fence permit.

Yes, as general contractor on your own primary residence (up to 6 units, no building over 3 stories, one property a year), with Form 401 and ID showing you live there. A masonry fence or wall also needs a Class A or B mason and drawings from an Illinois architect or structural engineer.
