FAQ
What typically affects the budget for a SB9 lot split project in Los Angeles?
An SB9 lot split budget in Los Angeles is the cost of turning one Encino lot into two legal lots: survey and civil, a tentative map or urban lot split application, new utility services to the second lot, fencing, and carrying two lots while conditions of approval are cleared. 121 Design Build maps those items before anyone prices a house.
Direct answer
The SB9 lot split budget is survey, civil, and two lots — not a house bid.
SB9 lot split cost in Los Angeles is driven by the map, not the millwork. A surveyor has to locate the existing house, setbacks, and a proposed cut. Civil work then has to show how the second lot gets access, drainage, and new utility services. Until those drawings exist, a construction bid is guessing.
121 Design Build, from Encino, treats the SB9 lot split budget as its own workstream: application, conditions of approval, recording, then later building permits. That is a different stack than an SB9 two-unit or ADU budget.
