Lake County, IL
Lake County, Illinois is not the permitting office for every city and village inside the county. Its building-permit page is aimed at unincorporated Lake County work, while the county permits page routes applicants across Planning, Building and Development, Transportation, Health, Public Works, and Stormwater Management. The forms page is unusually useful because it shows several projects handled as registrations or in-person alternatives while still pointing people to the Citizen Self Service e-portal.

Process signals
Lake County's Building Permits page frames the permit requirement around work in unincorporated Lake County, so the first check is whether the parcel is actually in the county building-review lane.
Building PermitsThe forms page repeatedly says applicants may apply online through the Citizen Self Service e-portal while also offering in-person registration forms for several smaller project categories.
Forms - Unincorporated Lake CountyThe county permits page groups Planning, Building and Development beside Transportation, Health, Public Works, and Stormwater Management, which means some projects can leave the pure building-permit lane early.

Some smaller scopes
The forms page distinguishes several registration forms from fuller permit paths, which can change both the paperwork and the expected fee path for small unincorporated-county projects.
Forms - Unincorporated Lake CountyEdge cases
Because Lake County lists Stormwater Management Commission, Public Works, Transportation, and Health Department permit paths beside Planning, Building and Development, site, driveway, utility, or drainage details can change the first department to contact.
PermitsLake County's open data page groups property, permits, codes, ordinances, building codes, code enforcement, and the Unified Development Ordinance, making parcel identity and county-code context part of the public research trail.
Property, Permits, Codes and OrdinancesLocal context
Lake County's history page notes that the courthouse became too small as the county grew, gained a large addition in 1922 and 1923, and later led to a modern courthouse completed in 1968 in downtown Waukegan.
This Moment in Lake County HistoryBecause the public permit sources separate unincorporated county review from municipal review, the local construction story starts with boundary and parcel identity before the applicant assumes which office owns the project.
