Cockroach Infestations: California Tenant Rights
Roaches in the kitchen, the cabinets, the bathroom, the kids' rooms. A can of spray is not a repair.
A cockroach infestation can make a California rental substandard. Health and Safety Code § 17920.3(a)(12) lists infestation of insects, vermin or rodents as a substandard condition, and Civil Code § 1941.1(a)(6) requires the building and common areas to be kept free of vermin. Because roaches move between units, effective treatment is often building-wide and repeated. Tenants living with an infestation after notice may be able to recover part of their rent and other damages.
Health risks of cockroaches
Cockroaches can carry bacteria such as salmonella and E. coli onto food and surfaces, and their droppings and shed skins are a well-known asthma and allergy trigger, especially for children.
What the landlord must do
- Hire professional pest control, with follow-up treatments

- Replacement of contaminated food and belongings

Frequently asked questions
Is a landlord responsible for cockroaches in California?
Generally yes, especially where the infestation comes from the building or other units. An infestation found by a health or code officer is a substandard condition.
How many treatments should the landlord do?
As many as it takes. Roach treatment usually requires follow-up visits, and treating only one unit in a building rarely works.
Can several tenants sue together?
Yes. When a whole building has the same problem, tenants can join one case and share the cost of experts.
Living with unsafe conditions, or hurt because someone was careless?
Tell us what happened. Consultations are free, and you pay nothing unless we recover for you.
