Q: Can my landlord email me my 72 hours notice? And also can they raise my rent without telling me

A: No, no, and no. While a landlord can, of course, email you a 72 hr. notice (as well as anything else), it is not enforceable or effective. If they try to evict you based upon it, you will likely win if you fight it in court and recover your court costs and attorney's fees. Rent can only be legally raised in a month to month tenancy, after the first 12 months of occupancy, and with at least 90 days advanced written notice the is lawfully served (again, no email!) and which contains all the lawfully required information. The landlord can never lock a tenant out until after getting a court ordered eviction AND having the Sheriff remove them. If they do or try, it likely entitles the tenant to enter anyway and to collect damages from the landlord, along with their court costs and attorney's fees. These are all the sorts of cases that a landlord-tenant attorney might take on a contingency whereby after reviewing the facts and confirming the strength of your case, the attorney would take the case without charging you anything further but rather collecting their fees from the landlord upon prevailing or settling the case. If you somehow did not prevail, then your attorney simply would not get paid. So if you have any further problems, be sure to document everything as completely as possible - dates, times, exactly what was said or done, witnesses, etc. and review it all with a local landlord-tenant attorney. Good luck.
