where can i check for regulations in texas about clearance space beetwen shoping centers and houses?
Answers:
You need to find out if there are zoning laws in the location you are talking about. Much of Texas does not have zoning.
Personally I would never buy a home without knowing what is around me. The land behind you may be zoned for residential but you can never be sure what kind of residence will be built there.
