Tips
- Longmont does NOT fully delegate electrical permitting to the Colorado DORA State Electrical Board — the City directly reviews and issues electrical permits through Building Services, but contractors must hold the underlying Colorado State Master Electrician and Electrical Contractor licenses as a prerequisite to city registration.
- LPC (Longmont Power & Communications) — the city's own municipal electric utility — has exclusive authority over meter sets, removals, and disconnect/reconnect; unauthorized attempts by a contractor or homeowner are treated as meter tampering with potential fines and criminal referral.
- Overhead-to-underground service conversions require a call to LPC's Field Engineer (303-651-8386) BEFORE applying, to confirm feasibility.
Frequently asked questions
- Who issues electrical permits in Longmont — the city or the State of Colorado?
- The City of Longmont's Building Services division issues and reviews electrical permits for all work within city limits. However, electrical contractors must first hold a Colorado State Master Electrician License and a Colorado State Electrical Contractor License (issued by the state DORA Electrical Board) before they can register with the City of Longmont to pull permits — Longmont does not issue its own separate master/journeyman electrical trade license, but it does require its own contractor registration on top of the state license.
- Can I remove or reset my own electric meter in Longmont during a permit project?
- No. Per the City of Longmont's Residential and Commercial Electrical Permit Checklists, ONLY Longmont Power & Communications (LPC) staff may remove, install, or reconnect electric meters — there are no exceptions. Doing so as a contractor or homeowner is subject to meter-tampering fines and possible criminal prosecution.
