Maintenance in "smaller" buildings

What is considered "too high" maintenance these days for a smallish building in an excellent location that provides services like doorman, elevators, storage, laundry, live in super? Smallish, like 9 stories and maybe 40-50 units? I know that as of 18 months or 2 years ago, people were talking about $1.50-$2.00 psf, but maintenance costs have done nothing but skyrocket since. And it's also hard to tell how much credence to give to the "smaller building" argument when we're not talking about a 5 floor walkup. I have looked at a place where maintenance is $2.50 psf. Again, top location, the services I mentioned, etc. Most comps I see in the neighborhood (full service buildings) are much bigger (150 units or so), and they tend to have lower maintenance. Thanks a lot...
