[Ord. No. 3927 §4, 2-9-2015]
The zero lot line residential development provisions of this
Article are designed to provide a more affordable ownership housing
opportunity for a wide range of income groups while assuring compatibility
with, and maintaining the stability and quality of, existing neighborhoods;
to provide the opportunity for lower development costs and lower per-unit
land costs that subsequently lower the cost of housing for the consumer;
to provide an economical and logical response to high-cost infill
properties; to promote a more efficient utilization of land; and to
promote energy conservation.
