Use the Correct Will County Permit Portal, Avoid Jurisdiction Errors and Reach Final Approval
The first question is not “Which permit?” It is “Is the property in unincorporated Will County?” A Joliet, Plainfield, Bolingbrook or other municipal mailing address may still require the city or village building department instead of the county.
This guide gives you the county jurisdiction check, SmartGov application fields, permit-search method, current fee examples, contractor rules, inspection steps and closeout checks in a simple order.

Will County or a City/Village Building Department?
Use Will County Land Use when
- The construction site is in unincorporated Will County.
- The county GIS and parcel information do not place the site inside a municipality with its own building authority.
- The SmartGov portal recognizes the parcel under Will County.
- County staff confirms that the Building Division has jurisdiction.
Check the municipality first when
- The property is inside Joliet, Plainfield, Bolingbrook, Romeoville, New Lenox, Mokena or another city/village.
- The mailing address says one community but the parcel lies near a municipal boundary.
- The SmartGov address search does not return the property.
- The project involves both county right-of-way and municipal building work.

Will County Building Permit FAQs
Does the Will County Building Division handle every property in the county?
No. The county Building Division mainly handles unincorporated Will County. Properties inside cities and villages commonly use that municipality’s building department. Confirm the parcel and jurisdiction before applying.

Use the official Will County SmartGov Public Portal. Create and verify an account, choose Applications, select the correct permit type, enter the address or parcel, add the contractor and construction value, review the application and submit it.
How should I enter an address in SmartGov?
The county’s portal instructions say to enter the site address without periods and select the matching address from the list. For example, use “302 N Chicago” instead of “302 N. Chicago St.”
How do I search for an existing Will County permit?
Open SmartGov, choose Applications and search by permit number, address, owner, applicant or contractor. You may also use Parcel Search with the PIN entered without dashes.
When can I schedule an inspection online?
