What's a 'just cause' eviction vs no-fault?

Owner move-in is one of the permitted 'no-fault' reasons under most just-cause laws (CA AB 1482 included). BUT there are real conditions: the owner (or a specific qualifying family member) must actually intend to move in, occupy for at least 12 months, and be the named owner — not an LLC. In CA you're also entitled to relocation assistance equal to one month's rent (or rent waiver). Strict notice procedures apply. The single most common abuse: landlord serves OMI, tenant leaves, landlord doesn't move in and re-rents at higher market rate. That's actionable for damages and sometimes treble damages. Save the notice and check back in 6-12 months whether the unit actually was owner-occupied — many tenants win these cases retroactively.
