Code References

The calculations of the possible new additions to the existing building on this property are based on the state and local planning regulations applicable to this lot.

Read below few of the regulations we followed in this analysis.


One-Family District. These Districts are occupied almost entirely by single-family houses on lots 25 feet 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 feet 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.
