If you are talking 1970's I would not worry about it because building codes were pretty contempory at that time compared to the 1990's with the exception of requiring ground fault circuit breakers in the bedrooms and maybe carbon monoxide detectors.

For instance, landlords are supposed to supply working carbon monoxide detectors around here.

Quote from @John Carbone: Quote from @Ryan Moyer: Quote from @Bob Willis: I think market saturation is the culprit here more than the economy.  

We also verify the smoke and carbon monoxide detectors are in working order.

I will also be replacing all smoke and carbon monoxide detectors.

thanks @Kevin Carbon.

Section 8 rules aren't anything crazy things like no exposed wires, reset buttons on outlets in kitchen and bath, carbon monoxide/smoke monitors, windows in working order etc.

I use a receipt book (one for each property) that has carbon copies (one copy for me and one for the tenant). 

Here's my take:  (Warning: Long post)  As a RECF site that focuses only on Real-Estate Debt, they seems to be just a newer, carbon-copy of PatchOfLand.com, as far as I can tell...  

You may actually be surprised when you find out how many different forms you need: the lease agreement is the main piece, but the you have rules and regulations, smoke detector notice, carbon monoxide detector notice, pet agreement, move in / out inspection check list, pet agreement, lead based paint addendum and lead besaed paint pamphlet.
