If the plat of a residential subdivision containing one or more new streets has been duly filed in the Wayne County Clerk's office prior to the adoption or any amendment of this chapter, the lots of the subdivision may be developed with the lots and yards delineated on the plat and any provision of this chapter requiring larger lots or yards shall not apply to the subdivision for a period of three years from the date of such filing. If the plat is being filed in sections, the three years shall be computed from the last date of the filing of a section prior to such adoption. If an additional section is filed after such adoption but within the three-year period and less than one year of the period remains, the three-year period shall be extended as to such section only for one year from the date of its filing.

Where a lot in one ownership exists in two or more districts, the regulations for any one district may be extended into the other district or districts for a distance of not more than 20 feet. Extensions of more than 20 feet shall be permitted only by approval of the Zoning Board of Appeals.

Nothing contained in this chapter shall limit or restrict the height of a church spire, belfry, clock tower, chimney flue, elevator bulkhead, or television antenna.

Nothing contained in this chapter shall prevent the projection of an open fireproof escape or stairway into a rear yard or side yard for a distance not to exceed eight feet.

In any such parcel of land with an area or width less than prescribed for a lot in the district in which such lot is situated, which parcel was under one ownership on the effective date of this chapter and the owner thereof owned no adjoining land, said parcel may be used as a lot for any purpose permitted in the district, provided that there shall be compliance with all other regulations prescribed for the district by this chapter.

In any district, no lot may hereafter be used nor any building or structure erected, reconstructed, structurally altered or moved for use as a junkyard as defined in this chapter. (See § 150-5.)

At the intersection of two or more streets, no hedge, fence, wall or other obstruction to vision shall be permitted within the triangle of land bounded by the street right-of-way lines and a line connecting points on such right-of-way lines which are a distance of 30 feet from their intersection.

In any district, all storage of materials shall be behind the front line of the primary structure located on such premises. Any structure used for the storage of materials shall comply with all applicable setbacks. The foregoing requirements shall not apply to the placement of a temporary storage structure which remains on such premises for no more than two weeks in any 12 consecutive months.
