I'm looking at purchasing a property with a lot line wall abutting a maintenance alley owned by the apartment building next door. When this wall eventually deteriorates and needs to be repaired, what is the procedure for conducting the repairs, given that I will need access to their lot in order to do this?

Presumably, I will need to get permission from the apartment building to erect scaffolding in the alleyway. Could this be a potential headache? Might they try to extract some kind of payment from me in return for the right to conduct repairs?

Any advice would be very helpful. I'm a newbie to these these kind of issues.

Real property law 881. See article.
