Permit Fee Waivers

Due to periodic flooding and sewer back ups that has occurred in some areas of the Village over the last few years, the Village waives the Village's building permit fees for damage related to flooding as well as for the installation of flood control measures for existing construction.

In order to obtain a waiver from the fees, a waiver form (PDF) needs to be filled out with contact information and a complete description of the work and diagram. 

The permit will still be issued and contractors are required to be licensed and bonded with the Village under normal regulations. The Village may conduct preliminary inspections prior to issuing flood repair related permits. 

Permit and waiver request applications are available online and can also be picked up at the Village Hall. If you have questions, please contact the Community Development Department at (708)579-2320.

Rear Yard Flooding Assistance

Residents that experience rear yard flooding can contact the Community Development Department at (708) 579-2320 to receive an evaluation of the conditions and suggestions to mitigate the problem.  The Village also provides discounted engineering services upon request.

Expedited Permit Review

The Community Development Department will do everything possible to expedite permits related to flooding and sewer back ups. 

Stormwater Management for New Construction

The Village requires stormwater management in the form of on-site detention for all new single family homes, multi-family residential, and non-residential buildings.  When improvements are made to existing homes, like new patios or additions, these projects are also required to demonstrate compliance with Village grading and stormwater requirements.  In La Grange, the majority of the systems are located underground.  As sites are redeveloped, the Village's requirements ensure that stormwater management is included.  

Preventing Sewer Backups

  • Have a qualified, experienced plumber who guarantees their work inspect your basement. To protect your home from sewer backups, have a check valve or overhead sewer installed. A licensed contractor and permits are required for this work. These home improvements will prevent sewer backups if properly installed.
  • Disconnect your home’s downspouts so they drain onto pervious (absorbent) surfaces instead of into the sewer system. It is important to make sure the disconnected downspout does not direct water toward your foundation or a neighbor’s foundation. Consider directing flow to a rain barrel or rain garden area.
  • You can connect downspouts to rain barrels (available from the Metropolitan Water Reclamation District (MWRD) and other suppliers) to save the rainwater for reuse.
  • Consider replacing your driveway and other paved areas on your property with previous surfaces that can absorb stormwater. If permeable pavers are used for a driveway, walkway, patio, etc. then they do not count towards lot coverage. The installation of the pavers must also include proper drainage approved by the Village.
  • Has your lateral connection been inspected for blockages or damage that could cause basement backups?
