Before & After Applying
To ensure the building permit process runs smoothly, it is advised that you contact the department prior to making the application to ascertain what the requirements are for the project you wish to undertake. Once your permit has been reviewed and is approved for pick-up, a member of the department will contact you.

With every approved permit, you will receive a permit card, which must be posted on the job or construction site along with any approved plans. As construction proceeds, you must call in for the required inspections to ensure that the project is built safely and is consistent with all Village codes and ordinances.
