Colorado doesn’t write its own elevator code from scratch. Under state statute, Colorado adopts ASME A17.1, ASME A17.3, ASME A18.1, and ASCE 21 as the governing standards for the design, construction, alteration, and inspection of elevators and related conveyances, and it applies those same standards regardless of which city or county the project sits in.
The Colorado Division of Oil and Public Safety administers this framework through its Conveyance Program, and the agency can delegate enforcement to a local Authority Having Jurisdiction where one exists. That means the underlying elevator code requirements don’t change from Denver to Colorado Springs to Glenwood Springs, but who reviews your application and how quickly they move through it can.
For a builder or architect specifying an elevator, the practical upshot is that state code governs the engineering while local process governs the timeline.
How Elevator Code Requirements Differ by System Type
ASME A17.1 carves out separate provisions for LULA, residential, and full passenger systems, and each carries its own limits on size, travel, and application.
LULA Elevators
A LULA elevator, short for limited use/limited application, is governed by Section 5.2 of ASME A17.1. These systems are built for low-rise commercial buildings such as churches, small offices, and multi-tenant properties. The code caps their travel distance, number of stops, speed, and car capacity in exchange for a smaller footprint and simpler installation.
LULA systems still have to meet ADA accessibility requirements, and most jurisdictions expect the reduced shaft and pit dimensions to be confirmed against manufacturer specifications before construction drawings are finalized.
Full Passenger Elevators
Full passenger elevators, the kind found in multi-story commercial and multifamily buildings, fall under the general provisions of ASME A17.1 rather than a limited-use carve-out. That means fewer restrictions on travel distance and capacity, but more extensive requirements around machine room construction, fire service operation, and emergency communication.
Commercial projects also tend to involve more coordination between the elevator contractor and the project’s fire protection and life safety consultants, since passenger elevator code compliance touches egress and fire-rated assemblies in ways that residential and LULA systems typically don’t.
Residential Elevators
Private residence elevators fall under Section 5.3 of ASME A17.1, and the residential elevator code requirements here are written specifically for single-family, owner-occupied applications. A residential elevator installed in a duplex, accessory dwelling unit, or any structure with more than one dwelling unit can trigger a different code classification, a detail worth confirming with your elevator contractor before finalizing floor plans.
Hoistway enclosure, door interlocks, and communication requirements are all addressed under this section, and getting the classification right at the outset avoids a redesign after permitting has already begun.
Getting these classifications right before the hoistway is framed is exactly the kind of coordination that keeps a project’s elevator code review moving. Morning Star works with builders and architects from schematic design through final inspection on every home elevator project.
The Colorado Elevator Permitting Process
Once the code classification is settled, the elevator permit process runs on two parallel tracks. The building permit moves through the local building department the same way it does for any other structural or mechanical scope, while the elevator-specific permit and inspection run through the Colorado Division of Oil and Public Safety or, in jurisdictions where OPS has delegated authority, through the local Authority Having Jurisdiction.
Both have to close before a certificate of occupancy can be issued, and because the elevator inspection typically can’t happen until the system is substantially complete, it tends to land late in the schedule, which is exactly why it needs to be planned early.
Registration and inspection carry separate state fees, and a Certificate of Operation is required before the elevator can legally run, regardless of how far along the rest of the building is.
Common Permitting Mistakes That Delay Projects
Most permitting delays trace back to the same handful of avoidable issues, and they show up whether the project is a custom home or a small commercial retrofit.
Incomplete or Mismatched Applications
A permit application that’s missing engineering documents, or that lists specifications that don’t match the equipment actually being installed, gets kicked back for correction. This is especially common when the elevator contractor isn’t looped in until after the permit set has already been drawn, since dimensional and electrical details in the application need to match the equipment being specified.
Specifying the Wrong Code Category
Confusing a LULA elevator with a residential system, or assuming a passenger elevator’s requirements apply to a smaller accessibility lift, produces a permit application built around the wrong section of the elevator code. Reviewers catch this quickly, and the correction usually means resubmitting rather than amending, which adds weeks rather than days to the timeline.
Missing Engineering Sign-Off
Structural and electrical engineering documentation has to accompany the application for most installations, and a set that’s missing a stamped drawing or a required calculation will sit until it’s resubmitted complete. Coordinating this documentation with the elevator contractor before submission, rather than after a rejection, is one of the simplest ways to keep a project on schedule.
Bringing an Elevator Specialist In Early
The earlier an elevator contractor gets involved, the fewer surprises show up during permitting and construction. Hoistway dimensions, electrical rough-in specifications, and pit depth all depend on the specific system being specified, and those decisions are far cheaper to make on paper during schematic design than to correct after framing is complete.
Builders working on luxury home elevator projects in particular benefit from this early coordination, since custom finish selections and equipment configuration decisions compound the number of details that need to be locked down before permitting can move forward cleanly. A site visit and a set of preliminary specifications at the design phase catch the coordination issues that would otherwise surface as change orders.
Inspection and Acceptance After Installation
Getting a permit approved is only half the process. The elevator still has to pass acceptance testing before it can legally operate.
What the Inspection Covers
An acceptance inspection verifies that the installed system matches the approved permit, tests safety devices, governors, and door interlocks, and confirms the equipment performs within its rated speed and capacity. For commercial elevator installations, including LULA systems, this inspection is a required step before a certificate of occupancy can be issued, which puts it squarely on the project’s critical path.
Scheduling the Final Inspection
Inspector availability varies by jurisdiction and season, and requesting the final inspection with enough lead time is one of the most overlooked scheduling items on a project. A home accessibility elevator or any residential system awaiting final sign-off should have its inspection request submitted as soon as the equipment is substantially complete, not after the rest of the punch list is finished.
Work With a Team That Handles the Permitting
Colorado’s elevator code isn’t complicated once you know which section applies to your project, but the permitting process rewards builders and architects who plan for it rather than react to it. Morning Star has worked alongside Colorado builders and architects on residential, LULA, and commercial elevator projects for years, coordinating spec development, rough-in requirements, and permit support from schematic design through final inspection.
Reach out to our team before your next project’s permit set goes in, and let’s make sure the code and the paperwork are both handled right the first time.
