One of the most common questions we get regarding Los Angeles Small Lot Subdivision is if it is permitted in a R2 zone. In general, the Small Lot Ordinance prohibits small lot projects in the R2 zone, unless the project meets the following strict criteria (excerpt from ordinance):
The dwelling units in the proposed small lot subdivision have a side lot line adjoining a lot in a commercial or industrial zone (meaning it has to be right next to) and
1) The use, including the accessory buildings and uses and required yards, does not extend more than 65 feet from the boundary of the less restrictive zone it adjoins; and
2) The lot area per dwelling unit or guest room regulations of the RD 1.5 zone shall apply to the uses.
So, essentially the R2 lot in question needs to be immediately adjacent to a "C" or "M" zone. As you can imagine, this is a rare occurrence within the city of Los Angeles. The city basically doesn't encourage Small Lot Subdivision in the R2 zone because it's considered too sensitive for a subdivision. This, however, is not to be confused with the RD2 zone, in which Small Lot Subdivision is permitted.
