Building permits in Unincorporated Fulton County

Unincorporated Fulton County does not issue residential building permits. Fulton County issues only a zoning permit (formerly called a building permit) through its Planning and Zoning Office; the office states it does not interpret or enforce building codes. No county building code permit or inspection.

That does not make the work unregulated. The construction standard still applies, trade licensing still applies, and separate approvals such as on-site sewage, floodplain development, and driveway access are handled by other offices. Below are the contact details for the office to ask, plus guides for the projects homeowners ask about most.

Construction in Unincorporated Fulton County is governed by the building code adopted locally, because Illinois historically had no single statewide building code and municipalities and counties adopt and enforce their own, many of them home-rule. Most base their residential rules on an edition of the International Residential Code (IRC), and under Public Act 103-0510 a statewide minimum took effect January 1, 2025 requiring local residential codes to be at least as stringent as an IRC-based standard, though permits are still issued and inspected locally. The City of Chicago is a notable exception, enforcing its own Chicago Construction Codes. Illinois sets no statewide dollar amount that waives a permit, so the thresholds and fees that decide when one is required vary by jurisdiction. Always confirm what Unincorporated Fulton County requires with the local building department before you begin.

Permit FAQs for Unincorporated Fulton County

Do I need a building permit in Unincorporated Fulton County?
Fulton County issues only a zoning permit (formerly called a building permit) through its Planning and Zoning Office; the office states it does not interpret or enforce building codes. No county building code permit or inspection.
Who issues building permits in Unincorporated Fulton County?
Nobody does. Unincorporated Fulton County does not run a residential building permit program, which is why this page lists Planning & Zoning Office as the office to contact rather than as a permit issuer. Your mailing city is not always the authority over your property, so confirm which jurisdiction you are actually in before assuming this applies to you.
What still applies in Unincorporated Fulton County if there is no building permit?
The construction standard does. Work must still meet the building code adopted locally, which in most Illinois jurisdictions is an edition of the International Residential Code (IRC), subject to a statewide baseline that took effect January 1, 2025 and, in the City of Chicago, the separate Chicago Construction Codes, and trade licensing rules apply regardless of whether a permit is issued. Separate approvals such as on-site sewage, floodplain development, and driveway access to a public road are handled by other offices and are unaffected. Ask Planning & Zoning Office which of those reach your property before you start.
