Sherman Oaks · SB 9 lot split
One lot, divided in two: the 1950s ranch stayed and was refinished, and a new two-story residence went up where the side yard used to be — each with its own address, driveway and yard.

What an SB 9 lot split costs
Budget $300,000 to $700,000 for the whole job: the split itself, the new residence, and the new driveway, sewer lateral, water and electrical service the second parcel needs. The lot split and its surveys usually account for $40,000 to $90,000 of that before a shovel moves. Where the existing house can stay where it is, the cost falls sharply. Where it has to shift to make room, the same project costs more and takes longer.
What the law allows, and how long it takes
SB 9 lets a single-family lot divide into two, with up to two homes of no more than two stories on the result, and the local agency cannot refuse a project that meets the objective standards. In practice income, historic status and prior demolitions decide whether a lot qualifies, so the first step is a feasibility read of the parcel. From there, expect four to eight months for the split and its entitlements, then the usual permit timeline for the new house, then construction.
Keep the house, or start the lot over
Most of our SB 9 work keeps the original house and adds a second residence behind it, which is the cheaper path and the one that keeps the block intact. The new parcel needs its own utilities, frontage and address before it can be sold or financed. We handle that coordination with the city and the utility companies, and we build the new home under the same contract.
