Large 3+ acre lot for sale in the well-established and sought-after Eichler neighborhood in the Castro Valley Hills. The Owners have taken the first step to Pre-Screen the lot for an SB 9 Development to allow for BOTH an Urban lot split (2 lots) AND the development of up to two units per lot (a total of 4 units). SB 9Pre-Screening has been completed by the County, and the property is considered Preliminarily Eligible. This is not a guarantee for final approval. Buyer would need to continue the process with the County to determine final eligibility and, if possible, to obtain final approval. Buyer is advised to contact the County for all rules and requirements and to satisfy themselves.
