Tenant refusing access to show apt

[Luca Mastrangelo]

Hi everyone. I'm in CT.  One of my tenants are moving out end of July. This past weekend I told them I wanted to show the apt for a few hours next Tues. during the day from like 12-4 or something.  They pushed back and said no that doesn't work because they work from home and their work is sensitive in nature and not supposed to have people around when they're working.  They said I could come on the weekend or after 6 pm. I am traveling from MA to CT (~2 hours) for other reasons that day and figured I'd take advantage of being there and get as many people as I can looking at the apt. I can't make it work after 6pm that day. 

ive looked at my lease and state laws but this situation is a bit grey. It seems like I need to give them reasonable notice, which I did, but of they refuse then I'd need to get a lawyer involved to compel them to allow access or it's considered a breach of the lease and eviction can start. Those costs would be recoverable from the tenant if ruled in my favor.  Since they are month to month I think I only need to give them 3 days notice if I plan to not allow the next month but this all seems pretty drastic for this. 

I'm trying to find a way to make this work like have the person go into the office this one day etc but they're counter offer is come after 6 or on the weekend which doesn't work for me and I'd like to start showing the apt as soon as possible since 8/1 is approaching and Im not available to show it this weekend. I also offered them if they want to show it for me over this weekend then that would alleviate this need but they didn't want to do that either.  

anyone have experience in CT with this situation? Ever get a lawyer and judge involved?  

thanks in advance
