The owner who can approve a video lives in another state
A downtown unit is somebody's business, and the person with authority to say yes is rarely the person who let you in.
A guest opens the door in The Gulch. A cleaner opens one in Donelson. Neither can give you permission to publish anything, and the manager who booked the call often cannot either, because the property belongs to an owner who bought it as an investment and has never seen the mechanical closet.
Ask the manager to get that approval in writing once, for the whole portfolio, rather than chasing it at every call. Managers handle worse paperwork than that before lunch, and an operator who trusts you with a lockbox code will usually say yes to a camera pointed at equipment.
The occupied unit is the harder question and the answer is simpler than people want it to be. If a guest is in there, do not film. A paying guest agreed to a repair, not to appearing in a contractor's video, and a complaint about it goes straight to the platform the owner depends on.
Shoot what you were called for. A rooftop condenser on a downtown building, an air handler in a closet nobody designed for service, a filter that has not been touched since the last turnover, the return that somebody framed a headboard against.
Do the talking later. Narration recorded in the truck afterward sounds better than a whisper in a unit being cleaned around you, and it keeps a stranger's voice out of the clip entirely.
