What Happens If My Landlord Will Not Fix My Heat, Hot Water, or Mold?

When a landlord ignores broken heat, no hot water, or spreading mold, California tenants are not powerless. State law gives renters several escalating remedies, but using them correctly matters. The wrong move can put your tenancy at risk, while the right sequence builds a strong record.

The Implied Warranty of Habitability

Every California rental carries a legally implied promise that the unit will stay livable for the whole tenancy. Rooted in the Green v. Superior Court decision and codified in Civil Code section 1941.1, the minimum standards include working heat, hot and cold water, a sound roof and weatherproofing, safe electrical systems, pest-free conditions, and sanitary facilities. Since 2016, visible mold that creates a health hazard is itself a habitability violation under Health and Safety Code section 17920.3, no matter the cause.

Step One: Notify Your Landlord in Writing and Keep Proof

Always put the request in writing. An email or certified letter creates a timestamped record. Under Civil Code section 1942, 30 days after written notice is presumed a reasonable repair window, although emergencies such as no heat in winter or a sewage backup call for much faster action. Photograph the defect with dated images and save every piece of correspondence.

Step Two: Repair and Deduct

If the landlord still does not act, Civil Code section 1942 lets a tenant hire a contractor and subtract the cost from rent, subject to two limits. The repair cannot exceed one month of rent, and the remedy can be used no more than twice in any 12-month period. The defect must materially affect health and safety, and the tenant must not have caused it.

Step Three: File a Code Enforcement Complaint

Tenants can report uninhabitable conditions to local housing or code enforcement. In the City of Los Angeles this is the LA Housing Department, and in unincorporated LA County it is the Department of Consumer and Business Affairs. A written inspection finding creates an official record and, if the problem is not fixed within 60 days, can trigger a rebuttable presumption of a habitability breach under Civil Code section 1942.4.

Step Four: Rent Withholding, a Higher-Risk Option

A tenant may withhold rent entirely when a landlord refuses to correct a serious habitability violation. This remedy is recognized, but it carries real risk. The landlord may file for eviction, and if a court decides the problems were not serious enough, the tenant can owe back rent and face removal. Anyone considering this should speak with an attorney first and set aside the withheld rent to show good faith.

When Conditions Become a Constructive Eviction

If conditions get so bad that no reasonable person could keep living there, such as months of sewage backup or dangerous mold making occupants sick, and the landlord still refuses to act, the tenant may be constructively evicted. A constructively evicted tenant can end the lease without penalty and may recover moving costs, the difference in rent, and in some cases emotional distress damages.
