So when you sign a contract you’re obviously opting in to the rules and requirements that they enforce.
A lot are strong on pets and/or smoking in the property
Some are very strict on decorating
Some add rules about how many people can be there at once (Try stopping a James party )
Mine has now enforced an automatic water stopper if there’s constant water for more than 10 minutes (after flooding in other apartments in the building)
I’m curious what rules have been set that you thought were commonplace - but was just the landlord (or whomever manages the listing) being overzealous
