When a unit's furnace is located in another unit

[Simonsays]

Reviewing a two family dwelling using the 2019 Residential Code of Ohio where unit A's furnace can only be accessed through the basement stair in unit B. The text in Section 1305 doesn't appear to prohibit this arrangement but I feel that access through a potentially locked space is wrong. Thoughts?

Is there a power shut-off switch in unit A?

Simonsays, Do you adopt the electrical part of the IRC or use the NEC?

See: NEC 240.24 (B) 1

1. (B)Occupancy. Each occupant shall have ready access to all overcurrent devices protecting the conductors supplying that occupancy, unless otherwise permitted in 240.24(B)(1) and (B)(2).
   1. (1)Service and Feeder Overcurrent Devices. Where electric service and electrical maintenance are provided by the building management and where these are under continuous building management supervision, the service overcurrent devices and feeder overcurrent devices supplying more than one occupancy shall be permitted to be accessible only to authorized management personnel in the following:
      1. (1)Multiple-occupancy buildings
      2. (2)Guest rooms or guest suites
   2. (2)Branch-Circuit Overcurrent Devices. Where electric service and electrical maintenance are provided by the building management and where these are under continuous building management supervision, the branch-circuit overcurrent devices supplying any guest rooms or guest suites without permanent provisions for cooking shall be permitted to be accessible only to authorized management personnel.

Not sure that either of those sections actually get you there....
