What fiber work covers
Premises fiber in the Denver metro typically includes pulling single-mode or multimode cable, fusion or connector terminations, patch panels, and media converters or ONTs at the demarc. Indoor pathways use existing conduit, J-hooks, or new raceway. Outdoor work on the lot is different from work in the public right-of-way. A municipally licensed Denver general contractor coordinates the project and licensed specialty trades for low-voltage and electrical portions. Cost is project-specific and depends on run length, terminations, and whether conduit is new.
text
Indoor electrical vs street ROW
Hardwired racks, PoE switches, and new circuits go through City and County of Denver Community Planning and Development electrical permits. Colorado DORA regulates electrical licensing. Fiber or power conduit in the public ROW is a DOTI construction/occupancy permit, and longer conduit runs may need a Utility Plan Review. Zoning telecommunications permits cover antennas and ground equipment on private property, not ordinary indoor premises cabling.
text
Permits and who coordinates the work
CPD handles electrical permits for line-voltage work tied to the fiber plant. DOTI handles street cuts and ROW occupancy when the drop leaves the property. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades for fiber-optic scopes.

What buyers should prepare
Whether this is an indoor backbone or a street drop, existing conduit photos, desired termination rooms, and city or county.
FAQ
Common questions
Do indoor fiber runs need a Denver permit?
The fiber itself is often low-voltage. New circuits, hardwired racks, or line-voltage work typically need a CPD electrical permit.
Who handles fiber permits and licensing?
A municipally licensed Denver general contractor coordinates the project and licensed specialty trades. Colorado has no statewide general contractor license.
When does DOTI get involved?
When conduit or a street cut is in the public right-of-way. That is a ROW construction or occupancy permit, sometimes with a Utility Plan Review.
Single-mode or multimode?
Single-mode is typical for longer campus or ISP drops. Multimode is still common for short indoor backbones. Match the optics at both ends.
What information helps define scope?
Run length, indoor vs ROW, existing conduit, termination locations, and city or county.
