- Mahomet: Mahomet requires a roof-mounted solar array permit, approved and paid before work starts, with a structural engineer's statement and installation to the 2021 International Residential Code and 2020 National Electrical Code. HOA approval may also be needed.
- Urbana: Urbana has earned a SolSmart Gold designation, a national program that recognizes communities for making solar permitting and zoning easier.
