The government likes to put its rules on everything and the housing market is surly one thing it wants to control as people can be screwed out of large sums of money.

You Will need a permit for window replacements, as per regulations anyway.

@Joshua Dorkin Can you also make the pipeline and political propaganda from the Harper government {Canadian Federal Government} disappear?

I know that the commercial sites don't generally allow you to resell their data, but I generate my own data from public sources (eg: government web-sites).I use the data personally to assess the market, generate trends/leads, etc, but I was thinking the other day that other people might be interested in the data.Thanks!

Is anyone aware of any similar acts, rules, regulations, laws, etc., in states of Oregon, Nevada or California?

Unfortunately the government is cracking down on loan requirements so renting your current home to purchase a smaller multi-unit most likely won't qualify (a few of my investors have run into this problem).

State Governments would never give private companies access to that information. 

They're regulated and have liability.  

In short, you may want to verify with the laws that govern the project location to determine what requirements may exist there in so much as with whom you are allowed to contract with.And regardless of whether your hire a GC or not, every single subcontractor should have liability insurance (and worker's comp or a waiver if allowed).  

It's the federal government though so you can bet that they aren't very flexible and can't make changes or exceptions when someone messes up a bid.
