How do I handle a tenant Airbnb-ing my unit?

3-day cure or quit citing the no-sublet/no-STR clause. Cure = remove the listing and end any active short-term arrangements. AB 1482 lists unauthorized subletting as an at-fault just cause.

How do I prove the subletting?

Screenshots of the listing, booking confirmations if obtainable, photographs of unfamiliar occupants, statements from neighbors. Most STR violations are documented through platform screenshots.

What if my lease doesn't prohibit subletting?

Civil Code generally requires landlord consent for subletting unless the lease expressly allows it. Without a specific clause, the default rule still favors the landlord — but lease language should be explicit going forward to avoid ambiguity.

Is sub-subletting different?

Sub-subletting (the original tenant sublets, the subtenant then sublets further) is generally treated as more egregious and may rise to incurable conduct supporting a 3-day unconditional quit rather than cure or quit.

Does city STR enforcement help me?

Indirectly. Cities with STR licensing (LA, San Diego, Newport Beach) monitor platforms against licenses. A tenant operating unlicensed STR is violating both the lease and city law. City enforcement actions create useful documentation for the landlord.
