Controller Replacement in an Occupied 1962 Office Building
An owner of a 1962 four-stop office building wants to replace the relay controller with a solid-state controller and replace the car door operator. The elevator is a geared traction unit rated 2,500 lb at 200 fpm. The owner calls the work 'maintenance' and does not want plan review or a full modernization. A pre-bid walk reveals a 22 in. car-top clearance, a 48 in. pit with no ladder, no car-top stop switch, and no pit stop switch. The mechanic is asked to sign the permit application and start work Monday. The building will remain occupied, and the owner wants one elevator kept running during the work. The local inspector has not been contacted, and the owner has a signed proposal that lists only controller and door operator.
1. How should the proposed controller and door operator work be classified under Ohio's adopted elevator code, and which code requirements apply?

This is not maintenance. Replacing a relay controller with a solid-state controller and replacing the car door operator are alterations under the adopted ASME A17.1/CSA B44, because they change the elevator's equipment rather than restore it to its original condition. Ohio's rules adopt A17.1 for new installations and alterations, and A17.3 for existing elevators. The altered components must comply with A17.1, while the existing elevator must continue to satisfy A17.3's mandatory requirements for existing installations. If the scope changes rated load, rated speed, or the entire driving machine, the alteration can trigger broader A17.1 compliance. The mechanic should not sign a permit application that describes the job as maintenance. A permit and plan review should be obtained, the scope should be stated accurately, and the AHJ should decide whether the alteration is limited or full. Signing a false scope exposes the mechanic and contractor to license discipline and leaves the owner without a valid inspection basis.
2. What should the mechanic do about the pit ladder, stop switches, and car-top clearance before accepting the job?

These are not optional items that can be ignored because they are 'existing.' A17.3 contains mandatory requirements for existing elevators, and the mechanic must inspect the hoistway, pit, and car top against them. The missing pit stop switch and car-top stop switch affect safe access and maintenance; the missing pit ladder affects safe pit entry where A17.3 requires a ladder; and the 22 in. car-top clearance must be evaluated against the refuge and clearance requirements for the existing installation. The mechanic should document each deficiency with measurements and photographs, give the owner a written list of corrections, and explain which items must be corrected before the alteration is accepted or before the elevator is returned to service. If the owner refuses, the mechanic should not certify the installation as code-compliant. The work may be proposed, but the permit and inspection must reflect all required corrections, not just the controller and door operator.
3. The owner says the deficiencies are 'existing conditions' and refuses to correct them. What are the mechanic's options?

The mechanic should not proceed as if the job were a simple maintenance repair. The options are to submit a corrected scope that includes the A17.3 deficiencies, request a code interpretation from the AHJ, or decline the work. The mechanic must not sign a permit application, place the elevator in service, or issue a test report that implies compliance when known hazards remain. If the elevator is already operating with a missing stop switch or unsafe pit access, the mechanic should place it out of service, tag it, and notify the owner in writing. The AHJ should be contacted when the owner refuses to correct a safety-related violation. Taking the cash or signing off to keep the job would create personal and contractor liability, and it could result in license discipline. The professional answer is to document the refusal, preserve the written notice, and let the AHJ resolve the dispute.
