Building permits in Highland Park

Most construction, renovation, and repair work in Highland Park, Lake County needs a building permit from Community Development Department. Below are the office's contact details and online portal, plus step-by-step guides for the projects homeowners ask about most, from roofing and solar to fences, sheds, pools, and HVAC.

Construction in Highland Park 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 Highland Park requires with the local building department before you begin.

Permit FAQs for Highland Park

Do I need a building permit in Highland Park?
Most construction, renovation, and repair work in Highland Park needs a permit, including structural changes, electrical, plumbing, mechanical, roofing, and pools. Small cosmetic work is sometimes exempt. Every project 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, even when a permit is not required.

Who issues building permits in Highland Park?
Community Development Department issues permits for property inside Highland Park, Lake County. Your mailing city is not always the authority that permits your property, so confirm the jurisdiction before you apply. This page lists the department's phone, address, website, and online portal.
Can I pull my own permit as a homeowner in Highland Park?
In Highland Park, a homeowner can generally pull their own building permit and act as their own contractor on a home they own and occupy. Illinois does not license general contractors at the state level, so there is no statewide general-contractor license to hold, though some municipalities require local contractor registration and the state does license certain trades (for example, plumbers under the Illinois Plumbing License Law, 225 ILCS 320, and roofing contractors under the Illinois Roofing Industry Licensing Act, 225 ILCS 335). Whoever does the work, you must still obtain the permits Highland Park requires and pass all inspections.
Is there a dollar amount under which no permit is needed in Highland Park?
Not statewide. Illinois sets no statewide dollar threshold that waives a building permit, so whether small or cosmetic work needs a permit is decided locally. Confirm the exempt-work list and any value threshold with Community Development Department before you start.
How much does a permit cost and how long does it take in Highland Park?
Fees and review times are set locally and change often, so confirm the current numbers with Community Development Department or its online portal. Fees are usually based on the value of the work or a fixed schedule, and simple residential permits are frequently reviewed faster than new construction.
