Office-to-Hotel Conversion With an Existing Traction Elevator
A 1968 six-story office building is being converted to a 90-room hotel. It has one geared traction elevator: 2,500 lb capacity, 200 fpm, six stops, original relay controller, original two-speed car door operator, and no firefighter's service. The owner's scope is cosmetic cab finishes, LED lighting, a new solid-state controller, a new door operator, and a card-reader access system. The machine, ropes, sheaves, guide rails, and hoistway construction are untouched. The building is getting a new addressable fire alarm system. The owner's architect says the work is just a modernization and wants to keep the existing A17.3 compliance approach. The local AHJ has already classified the project as an alteration and requires a permit. The elevator is the only vertical transportation in the building, and the hotel plans to open in phases.
1. How should the mechanic classify the controller and door-operator replacement, and which code path should govern? Explain the reasoning.

The work is an alteration, not routine repair. Replacing the controller and door operator changes the elevator's operation, control logic, and door safety behavior; those are not cosmetic finishes. The existing elevator may remain largely under A17.3 for unaltered components, but the altered components must be evaluated under the current A17.1 requirements adopted by the jurisdiction. The change from office to hotel also matters: a change of occupancy can trigger additional requirements under the local building code, even when the elevator equipment scope is limited. The mechanic should not let the architect's label control the decision. The correct process is to compare the permit scope, the AHJ alteration classification, and the adopted code editions, then document which components are altered and which remain existing. Where A17.1 and A17.3 give different results, the stricter applicable requirement for the altered work should be followed unless the AHJ grants a specific alternative.
2. Identify the fire-service and door-related items that this alteration likely triggers, and explain why cosmetic cab work alone would not.

Because the building is adding a fire alarm system and the occupancy is becoming a hotel, the altered controller will likely need firefighter's service consistent with the adopted code: Phase I recall on alarm, Phase II car-top or in-car operation, and the associated key switches, indicators, and wiring. Replacing the door operator also affects door timing, reopening, and the interface with the door lock monitoring and interlock circuits. Those items must be tested as part of the alteration. Cosmetic cab work alone would not normally trigger a controller-level fire-service upgrade, because it does not change the operating system or the fire recall logic. The distinction is functional effect, not price or appearance. If the new controller can accept fire-service inputs but they are not installed, the elevator may pass a basic run test yet fail the alteration inspection. The mechanic should require a written sequence of operation and test the fire recall, door reopen, and interlock functions before the first hotel floor opens.
3. Outline the sequence from permit to return to service, including what must be documented before the hotel opens.

The sequence should start with a permit and approved scope that identifies the altered components, the applicable code edition, and the fire-service interface. Before shutdown, the mechanic should survey existing conditions and photograph the hoistway, door locks, machine, and wiring. Installation should follow the approved drawings, with the controller and door operator installed and the fire alarm interface coordinated with the alarm contractor. Testing should include normal run, leveling, door operation, interlocks, door lock monitoring, fire recall Phase I and Phase II, emergency communication if required, and a load test where the alteration affects capacity or traction. Documentation should include the permit, inspection requests, test records, fault logs, as-built wiring changes, and a written statement of the code basis for unaltered existing components. Return to service should occur only after the AHJ inspection or authorized inspection agency accepts the alteration. Phased hotel opening means each affected elevator must be independently accepted before guest use.
