Welcome to the site officially @Kevin Theis.

It is not an official index and updated every 2 years it is a good reference in the real estate market.

He officially moved out without notice yesterday claiming that the house is not a good environment for him due to carpentry in the house and because he doesn't get along with his roommate any more.  

I know that you might need a licence to officially legally establish yourself as a bird dogger or something like that; I'm not really too sure.

I wrote to them and asked them to please let me know which law they're referencing, as I can't find anything and the response I got was :"well, there aren't any laws, but we asked various officials and they all think that it should be forbidden." - that's not how the law works. 

Every apartment in this 12 unit (2 beds) building has at least one hardwired, and of course the official fire alarm system which only detects extreem heat increases.Any suggestion on the best value of smoke/carbon combos?

I've contracted with an architect to design the prefabricated/modular high rise, and will have it overlooked by a team of civil engineers.My next steps would be to submit the proposals to city officials/zoning.

Is it possible to give him official notice that he is creating a nuisance? 

An update for anyone who visits this thread randomly:  Our GC, who has worked with the city numerous times, was able to submit questions regarding permits to a city official via email.  

Don't forget that you may have to get a demo permit in many areas,"This section highlights OSHA standards, standard interpretations (official letters of interpretation of the standards), and national consensus standards related to demolition.OSHANote: Twenty-five states, Puerto Rico and the Virgin Islands have OSHA-approved State Plansand have adopted their own standards and enforcement policies.
