Do you need a permit to replace kitchen cabinets or a vanity in La Grange Highlands, IL?

The county says all work in unincorporated Cook County, other than ordinary repairs as its building code defines them, requires a permit application. Its page doesn’t name cabinets, so ask before you order.

What does Cook County say?
The county’s building permits page (opens in a new tab) says: “All work in unincorporated Cook County, other than ordinary repairs subject to provisions of Section 102-105.3 of the Cook County Building Code... requires the submittal of a permit application.”
So the county starts from a permit application. The exception is ordinary repairs, as that section of its building code defines them.
What about swapping cabinets or a countertop in place?
The county’s page doesn’t name kitchen cabinets, countertops or vanities. Don’t assume a swap counts as an ordinary repair.
Most swaps still mean disconnecting the sink and hooking it back up, and a new countertop often goes in with a new sink or faucet. Mention those details when you ask the county, and ask before you order.

Replacing a vanity almost always touches the sink and faucet. Our guide to what to ask before buying a bathroom vanity covers the parts to ask about, and our bathroom vanities page lists every model.
