Building Permits

Effective January 1, 2022: All “over the counter” permits must be applied for online. Click here to access our online permitting system.  


The City of Chanhassen has adopted the 2020 Minnesota State Building Code, which adopts the 2018 International Building and Residential Codes, with amendments by reference. General contractors (or homeowners doing their own work) must obtain permits before beginning work.
  • Building Permits are required for many projects, including but not limited to, new construction, additions, alterations, decks, finished basements, pool, demolition, roofing, siding, and window replacement.
  • Many projects require a detailed plan review, so allow at least ten working days for your permit to be processed.
