Tips
- Because Deer Lodge County is not certified for electrical, the electrical portion of any solar/alternative-energy install is a STATE permit — apply directly with the Montana Building Codes Bureau, not the county Building Inspector.
- Grid-tied systems always require a licensed electrical contractor to pull a separate permit for the final interconnection, even for otherwise homeowner-installed systems.
- Confirm with the ADLC Building Inspector, (406) 563-4011, whether the structural roof-mounting scope of your specific project also requires a local Building Permit.
Frequently asked questions
- Does installing solar panels require a permit in Anaconda-Deer Lodge?
- Yes. The electrical connection portion requires a State Alternative Energy Permit from the Montana Building Codes Bureau (since Deer Lodge County is not certified for electrical). Grid-tied systems additionally require a licensed electrical contractor to obtain a separate permit for the final interconnection. Confirm with the ADLC Building Inspector whether the roof-mounting/structural scope also triggers a local Building Permit.
