Garden Sheds, et al

Until 1989, no outbuildings were allowed. Then without a vote it all changed without any rules for governing outbuilding construction. Who allows garden sheds to be constructed in front yards within the 10 foot setbacks? Amateurs for certain. Illiterate, most likely, since there are existing 1973 rules expressly forbidding building anything in the set back and that goes for fences as well.
