Tables (like use tables) may not copy cleanly, so check any table against the official code.
Confirm anything here with Erda planning before you rely on it.
(1) Any legal substandard lot created prior to January 10, 1975, or having been granted a special exception by Erda , and having less than the requirements for lot area or width for the zoning district in which it is located, may be used for a single family dwelling if it is located in a zoning district that permits single family dwellings.
(2) The method for determining side yard setback distances for lots described in Subsection (1) is to:
(a) determine the area of the lot;
(b) determine the equivalent zone by using Table 4-A;
(c) compare the actual front width with the equivalent zone frontage requirement;
(d) if the actual frontage equals or exceeds the equivalent zone frontage, use the setback distance of the equivalent zone; and
(e) if the actual frontage is less than the equivalent zone frontage, then use Table 4-B to determine the adjusted side yard setback.
(3) All setbacks other than side yard setbacks shall remain as stated in the equivalent zone.
(4) Notwithstanding anything to the contrary in this section, side yard setbacks in lots described in Subsection (1) shall not be less than eight feet.
