Not from as far back but my house was built in the early 1980's and my house deeds include the stipulation that I must maintain a garage attached to the property (so I can't convert it to extra living space) because the local government retain the right to convert the space into a decontamination shelter in the event of chemical, biological or nuclear attack. Had a good chuckle with my lawyer regarding it, don't think I'll be too concerned about where to keep my lawn mower if the city has been nuked.
