The fire protection aspects required by the building code, may indicate rated partitions, automatic sprinklers, alarm or smoke detection requirements, based on the nature of the occupancy, the size of the "fire area", the size and/or height/number of stories of the building or the type construction (combustible or not).
All that said, any building may or may not have rated fire partitions between tenants. Always check the plans. Tenants in covered malls are always required to be separated by minimum one-hour fire partitions. Strip malls may not have this requirement.
As far as the electrical code is concerned, worring about running wiring through one tenant's space to reach another is not our problem. Easements and right of way privilege is a concern of the lawyers and real estate agents. There may be security concerns of one or another tenant, but usually we can run conduit through the ceiling spaces of other tenants.
I once wired a "safe room" for the USAF where there was a two foot "forbidden zone" on all sides of the room. No wiring of any kind was allowed in this area, and motion detectors, laser eye beams and seismic detectors were mounted in the dead space. High tech for the time.
