If you think about it in the strict sense I would say yes. You should talk to the enforcement department during your consideration period. Just because they may not enforce it routinly, does not mean they give up the right to enforce it at any time. You are correct in your thinking. In trying to address a problem from public outcry, they created the problem you speak of. As I understand it it applies only If the property is near a school. It appears they did not consult with anyone in the business. It is to me a kneejerk reaction based on thinking the banks have a lot of money and people who buy these buidings must have a lot of money too. Also, if a buiding is in a bad location watchman costs could be more than the price of the property over time or eat into or eat up your profit during holding time.
