Is it against the law for the landlord to have them run extension cords up to their apartment with permission?

They are 3 months in to a year lease and are now asking for permission to sublet or reassign because they want to move sooner.

For example, last time I looked into it here in Chicago, SROs (single-room occupancy, aka half-way home or boarding home) had to stay that way, unless the owner was able to vacate the building entirely and rezone, which of course required the city's permission.

SO my question is....can I legally take back possession of my property, get it cleaned up and in shape for showing interested tenants without her "permission" to enter the house?

Once I get a property under contract or get permission from the owner to inspect , I will have a contractor and Sec 8 inspector there to make sure the property will be eligible for Sec 8 tenants if I plan on using a lease option to take ownership.

The fastest time I personally stopped a foreclosure was 4 days before the auction.The owner was so happy she asked for permission to hug me at the closing table.It's good to help people and make money at the same time.

However, without permission from the listing broker you can't advertise the property as yours.

You can certainly show the house if the tenant gives you permission to do so.

All I have to do is go there and acquire the tenants credit score and say I have their permission to do so?

California tax law means when grandma died, we kept her tax basis, taxes are like $650 a year, vs market taxes of like 4000.The mom has given me permission to explore leveraging that property into more properties... as long as in the long term, call it a year out (max)and going forward, she at LEAST cash flows 500-600 like she is now.
