Residential Window Replacement Registration Information

This registration form should be used only for window replacements.  No permit will be required for the replacement of the windows.  In all cases, the requirements listed here will apply.  This process is designed to maximize customer convenience. However, the customer always has the right to seek a permit and a follow-up inspection. The Village of Lake County reserves the right to inspect any construction performed whether permitted or registered. 

You may apply for a Building Registration within the Village of Lake Villa, click here. Registrations can also be applied for in person at the Lake Villa Village Hall. A non-refundable registration fee of $35.00 is required and can be made by cash, check or credit card.
