Accually Tim,
If you take a good look at your drivers mannual they do tell you not to hit people with the vehicle, as for people taking responsibility I beleive the owner did when she closed and went to look for another place so she could meet compliance.
Running a business has many aspects you need to know just like inspecting a building, can all of your receipt the books by heart? I beleive not, but what Frank lists if you open any standard book on opening a business I beleive you will find all the items he listed in it, but I doubt you will find anything on ADA compliance. You will also find make sure the building location complies with zoning, fire and building department requirements and get your approvals, which she did.
As for the other items like snow removal a copy of the town ordiances was handed to me by the zoning officer when I researched purchasing a used building and another about renting, the building department gave me a list of items I would need to comply with as did the fire inspector, non-however mentioned ADA.
I could buy a building, get all my CO's, not do any renovations, pay all my taxes, read some really good books but nothing points you to ADA compliance.
Except I know better working in this industry for all these years, the problem is it's in your wheel house, you work with it all the time, you find it hard to beleive others don't have a clue and the lack of direction one finds.
Take the book store owner for instance, she rented the building, moved in I am sure paid and had a fire inspection every year, I am guessing the fire inspector didn't find anything wrong with the access or he would have closed her down.
Now she gets a letter to comply or else, who is this person, what is the problem I have all my approvals.
Simply, ADA information is just not a thought because unless you do renovations to the building and HAVE to hire an architect or designer to do that renovation, you would be surprised how little is known outside that area and I doubt you will find a leasing office or agent that will offer up the information.
