Zoning
RH-1
Residential, House Districts, One-Family
These Districts are occupied almost entirely by single-family houses on lots 25 ft in width, without side yards. Floor sizes and building styles vary, but tend to be uniform within tracts developed in distinct time periods. Though built on separate lots, the structures have the appearance of small-scale row housing, rarely exceeding 35 ft in height. Front setbacks are common, and ground level open space is generous. In most cases the single-family character of these Districts has been maintained for a considerable time.
