There's two primary reasons- zoning, and speculative investment that keeps good land off of the market. This make land very expensive to developers and limits competition.

* R-1A: One home per lot or estate, unless the parcel exceeds 2,400 SF which allows for an additional home.
* R-2: Two homes on one parcel, only.
* R-2A: One home per every 1,650 square feet on a parcel. A typical residential parcel in Berkeley is about 5,300 square ft thus commonly three homes maximum.
