My suggestion to you would be to consult with the local building department. 

Your local building department should be able to help with that one. 

But you should at least attend some meetings and let them know you are a homeowner in the community and that you're interested in being an active participant.

You should visit all the meet ups we have here focused real estate investing, especially the one in little Havana!

This morning I’d gone over to the property to meet a contractor to follow up on some repairs cited in a recent Sec. 8 inspection.

Often in Sydney and can look to meet for a coffee or beer CheersLindsay

What i have been doing is asking several questions before I consider meeting face to face.   

Also, get a handyman referral or two, and meet them personally.

Sometimes they will talk directly to the owners but other times if you just contact their real estate department directly they will give you information to their tenant broker to follow up.National companies get submitted a lot what they deem to be subpar sites.
