An unenclosed, one (1) story porch, erected on piers, even though roofed over, may project into a required front, side or rear yard area a distance not to exceed six (6) feet and shall not be considered in the determination of the size of yards or lot coverage, provided, however, that such porch shall not be closer than four (4) feet at any point to any lot line, and that no building shall have such porches projecting into more than required side yard.
