You may have seen the story about the new statute in Texas allowing tenants to put mezuzot on their exterior doorways. Apparently, this was in reaction to a situation where a resident was prohibited from putting up a mezuzah by the rules of his apartment community. I was curious what Jewish law would have said about this situation. If a Jew finds himself living in an apartment complex that prohibits hanging anything in doorways, what is he supposed to do? Defy the ban and hang a mezuzah anyway? Move and incur substantial inconvenience, costs, and possibly lease violation penalties? Or do the property rights of the apartment complex owner simply override the biblical commandment?
