shady landlord behavior

By K

My soon to be former landlord frequently has major repair work done in the apartment complex but doesn’t give the standard 24 hr written/verbal notice of work being done to the tenants.  Just yesterday I came home after work to find that the laundry room had been gutted and would be closed for 3 days (and over a weekend!)  When I asked the apartment manager what the deal was and why no one had been notified, he claimed it was "an emergency" and there was mildew problems.  However, nothing needed any noticeably urgent repairs (i.e. a burst pipe).  Furthermore, I had noticed him doing a lot of his laundry late the previous night (as in he knew the laundry room would be closed for a few days).  The workmen were also repairing other things around the complex that had nothing to do with the laundry room, so clearly they had been notified ahead of time of the extra fix-it work to be done and there was no emergency. 
This type of thing had happened before with the roof.  They spent 3 days repairing and re-tarring the roof, but again no notice was given.  Roof work definitely needed to be done, but it wasn’t anything that couldn’t wait another 24 hours or more to let the tenants know.
When is major repair work allowed in apartment complexes without notice to the tenants?

I’ve also noticed other incidents that seem unethical/illegal and wonder if any type of complaint can or should be filed?

 – landlord used own key to open a tenant’s apartment when he didn’t answer his door.  The landlord had been called by the tenant and asked to stop by, but the tenant did not answer the door when the landlord knocked, so he opened the door himself.  I though this was illegal.  (I personally witnessed the entire incident)

– I allowed the aparment manager inside when I wasn’t home so he could install new smoke detectors.  When I came home, I noticed that a hole in the wall had been repaired, presumably by him.  Is this legal?  Was he allowed to do work in my apartment without my authorization just because I had allowed him to enter for another reason?

– I gave my 30 day notice which is up in 2 days.  My apartment manager knows I have almost completely moved out because he saw the moving van yesterday.  But I still have some small things left, and technically I am still renting the place for 2 more days.  But the apt manager has already started to store stuff in my back patio area (supplies from the laundry room repairs) because he assumes I am pretty much out of there.  Is this legal?  Can he enter the patio area without authorization? 

Thanks in advance for any advice!
