The Cook County Department of Building and Zoning provides reasonable rules and regulations governing the erection, construction, alteration, demolition, or relocation of all buildings and structures within designated single family, multi-family, commercial, industrial and public zoned districts of unincorporated Cook County. Contact Building & Zoning if you have additional questions not addressed on this site using the contact information above or the departments email contact form.
We have begun to post a series of information webcasts about Building and Zoing rules and regulations on You Tube. One series is directed toward non-building professionals, homeowners and business owners. The other series is directed towards architects and engineers. To view them please go to:
(1) The Permitting Process: Home and Building Owner Series
(2) Architects and Building Professionals Series
Another option to view our clips is to go to: www.youtube.com and search out Building and Zoning, Cook County Government, IL. Bookmark this site and stay tuned as we continue to produce these broadcasts!
If you are applying for a Building Permit, department representatives are available at Permit Workshops that will be held throughout the year at Leyden Town Hall. Residents of unincorporated Cook County can receive preliminary reviews and/or submit applications for building permits for projects such as decks, above ground pools, additions, sheds and other building projects.
Download the 2011 Permit Workshop flyer for more information.
Effective July 13, 2009, the Cook County Department of Building and Zoning now provides for permit customers to be able to pay their Building, Plumbing and Electrical Permit fees online. For more information, visit the Building Permit page on this site >>
