Property managers, do you allow owners to perfrom repairs?

Property Managers, do you allow your owners to make repairs to the property while tenant occupied? I'm not talking discretionary remodels, but needed repairs. 

In the past, I have preformed some repairs to a rental that was under management.  For example, one property had a collapsing sewer line. Plumbers were quoting 12-14K to replace a 50' sewer line 2' deep. Since the line was still functional, I had time to perform a permitted repair. I hired a licensed excavation guy, installed the replacement pipe, and had the city inspection done on day 1 and the line was function that evening. There was a portable toilet on site for the tenants to use. Got it done for less than 2k in 2 days. The 2 companies I have worked with never had a problem with this. But I'm finding that some property managers will not allow you to preform a repair on a tenant occupied property under any circumstance. I understand that point too. Some folks don't know what the hell they are doing, cut corners, take too long and expose the property manager to potential liability. What's your policy?
