A building permit is generally required for most construction, including new building construction and additions, garages, interior and exterior alterations, driveways, heating and air conditioning work, electrical and plumbing work, swimming pools, fences, patios, decks, sheds, re-roofing and siding. Routine maintenance that does not change existing electrical, plumbing or mechanical system or any structural walls will not require a permit. No permit is needed to change windows unless the window opening is being enlarged. Reshingling a roof does not require a permit. Building Permit Application Form.
Citizens can call the Building Department at 847-318-5291 or 5292 to find out if a project requires a building permit.
Most Building Permit applications are processed in less than a week; however, it may take up to 15 working days to obtain a Building Permit for larger construction projects. A large number of permits are processed within 24 hours. The time it takes to obtain a permit depends on the type of construction work being done and what needs to be reviewed.
Building Permits for residential structures are valid for a period of one year. If work is not completed within one year, the applicant may request up to a six month extension. A permit may be extended only once. Permits may be renewed after expiration but the applicant will have to pay half the cost of the original permit fee.
When considering building a new home, the size of the house that may be built is determined by the Zoning Ordinance. The floor area ratio, the amount of open (green) space, amount of lot coverage and the required setbacks all influence how big and where a house may be built on a zoning lot.
All new construction, including residential construction and major additions, but not including detached accessory structures on single family residential parcels, must be approved by the Appearance Commission prior to the issuance of a building permit. Permits should be applied for well in advance of the proposed construction starting date.
A permit is for your protection -- it assures that the work is permitted under the law and that it is checked by City inspectors to make sure the work was done properly.
