When an infestation can justify moving out
Possibly, but be careful. If a cockroach infestation makes a rental truly unlivable and the landlord will not fix it, California law may allow you to move out under a legal idea called "constructive eviction" — but doing it the wrong way can leave you owing rent.
Breaking a lease is a serious step. Constructive eviction generally requires severe conditions, notice to the landlord and a fair chance to fix the problem, and that you actually move out because the home is unlivable. If those pieces are not clearly in place, a landlord may argue you simply abandoned the lease and try to hold you responsible for the rest of the rent.
Because the risk is real, this is a decision to run past an attorney before you act. Before you move out over an infestation — or sign anything the landlord offers — a free, confidential review can help you avoid a costly mistake.
