CA SB393

Modifies requirements for defendants to seek an undertaking (security bond) from plaintiffs challenging low- or moderate-income housing development projects, now requiring grounds that the action is without merit and brought in bad faith, vexatiously, for delay, or to thwart the housing project's low- or moderate-income nature.

Allows plaintiffs responding to undertaking motions to present evidence of economic hardship and seek to limit the bond amount.

Requires courts to consider evidence of plaintiff's economic hardship when setting undertaking amounts and authorizes courts to decline imposing any bond if it would cause undue economic hardship to the plaintiff.

Maintains the $500,000 maximum cap on undertaking liability for defendant costs and damages.

Makes developers liable to plaintiffs for the cost of obtaining an undertaking if the developer subsequently changes the housing plan in bad faith so it no longer meets low- or moderate-income housing requirements.
