The optimal path here is stealth density: primary + ADU + JADU to maximize the returns on this deep lot. Note that the liquefaction hazard zone acts as a minor blocker, requiring structural soil engineering that increases foundation costs. However, nearby high-value comparable sales support strong ARV ceilings.
