In that case, you give them a 3 day  notice to comply or quit, along with a 30 day notice to terminate their tenancy.They don't have the right to deny you access with proper notice.  

You will have to comply with whatever the lease spells out.I definitely agree with GregS and others: no need to offer cash for keys upfront.  

At any time they do not want to comply with my requirements they are free to walk I will gladly find another prospect.

., I would comply with all the code violations as they would likely need to be remedied anyway at some point.  

Get a copy of the application form you filled out.download the landlord tenant laws for your state and review the application form for any wording that would apply.In my opinion the landlord is NUTS... no signed lease.. and he can't collect double rent.. for any days the prior tenant was in the unit. although this shouldn't even be part of the action.I'd write him a stiff hard point by point letter and say no harassment or have your lawyer do it. that you want a letter stating the matter is closed no further action will be taken by him and if he does not comply you will file a action with the Fair Housing department.  

You can require ALL tenants to exercise responsible animal ownership, protect the property, minimize chance of harm to other people, and maintain acceptable noise levels that do not interfere with neighbors' enjoyment of their own property.A well-written animal clause will require the tenant to:Provide proof of current shots, if applicableProvide proof of flea control medication, if applicableDisclose the name and contact information of the veterinarian caring for the animal, if applicable (hamsters, for example, probably do not have veterinarians)Keep dogs in a crate or on a leash at all times when outside the dwellingUse a pooper-scooper, whether on the leased premises or another's propertyVary locations of dog urination, so as not to burn shrubs or lawnEmpty cat litter boxes daily into outside receptaclesControl  excessive barking that disturbs the neighborsAllow monthly inspections for pet damageImmediately clean any pet discharges and immediately report any damageAssist with Twice monthly HVAC filter changes for long-haired animalsKeep pet food supplies in pest-proof containersI think that if you approach the problem in this manner, you will be more comfortable complying with Fair Housing laws.

She has been keeping the apartment clean and there have been no more problems with others living there, so apparently my verbal warnings, about non-tenants who were seen living there, were sufficient for her to change that and comply with the lease.

Inform her that if she can't comply then she is in violation of the lease and have the paperwork with you to hand to her to terminate the lease and start the process of her vacating the unit.3) You don't send HVAC techs to a rental 4 times.

One thing about Section 8 is that you have to jump through a lot of hoops to comply with the county before the checks will start rolling in.

Since the tenant provided you an address and you mailed it to that address, you have complied with the law.
