As the summer heat rolls across California, a critical question faces millions of renters: when indoor temperatures spike, does your landlord legally have to provide air conditioning?
For decades, California law has been crystal clear about a landlord’s obligation to provide heat during the winter. But as climate patterns shift and summer heat waves grow more severe, the legal framework is transforming. Entering the summer of 2026, the state is treating extreme indoor heat not as a minor seasonal inconvenience, but as a core tenant rights and habitability issue.
Our legal team at The Law Offices of Katherine Cohan, APLC is actively tracking these shifting regulations to ensure you are protected against dangerous living environments and landlord negligence.
Historically, California Civil Code Section 1941.1 did not explicitly mandate air conditioning unless a cooling system was already built into the unit when the lease was signed. However, recent legislative updates have fundamentally altered the regulatory landscape for landlords and tenants across the state.
An indoor temperature threshold of 82°F has fast become the most significant metric in California housing policy, backed by public health data connecting sustained heat above this level to severe heat-related illnesses.
| Regulation / Ordinance | Scope | Core Requirement |
|---|---|---|
|
SB 655 (Statewide Policy) |
Enacted state policy establishing that residential rentals must be capable of maintaining safe maximum indoor temperatures.
|
Amends the framework around Civil Code § 1941, allowing tenants to argue that excessive, health-threatening indoor heat breaches the implied warranty of habitability.

|
L.A. County Safe Indoor Temperature Ordinance |
Unincorporated L.A. County areas (and cities opting into the county health code). |
Mandates that all habitable rooms (bedrooms, living rooms, kitchens) must be capable of maintaining a maximum temperature of 82°F. |
|
L.A. City Council Motion |
City of Los Angeles jurisdiction. |
Unanimous vote advancing an ordinance to officially adopt the county’s 82°F maximum indoor temperature standard. |
One of the biggest friction points we see between tenants and property managers is the installation of window or portable air conditioning units. Older buildings often feature fragile electrical grids, leading some landlords to ban these devices entirely.
Under the newer local frameworks, landlords generally cannot prohibit you from installing a code-compliant, portable cooling device at your own expense.
If your rental is overheating and you plan to install a window or portable AC unit, following the proper legal procedure ensures you are fully insulated from unjust eviction or retaliation:
Ensure the cooling unit matches the window type, does not block emergency exit paths, and adheres strictly to the manufacturer’s safety guidelines. It cannot cause permanent structural alterations to the property.
Provide your landlord with at least five calendar days of advance written notice (via email, text, or certified mail) stating your intention to install the portable cooling device. This gives the property manager a chance to raise valid, code-based safety concerns.
Measure the temperature exactly three feet above the floor in the center of the room. Take timestamped photos of the thermometer reading if temperatures cross the 82°F mark to build an official record of the unit’s conditions.
If you follow these guidelines, the landlord is explicitly restricted from passing on capital improvement costs for the installation or using the device as a ground for lease termination.
When an existing, landlord-provided AC system breaks down during a heat wave, it triggers the standard repair timelines for an urgent habitability defect. Because extreme summer heat poses an immediate health risk, a broken cooling system is not a minor aesthetic issue; it demands an expedited turnaround.
If a landlord fails to address a broken AC unit or ignores severe cooling deficiencies that push indoor temperatures into dangerous zones, California tenants have a specific legal toolkit available:
If your landlord is forcing you to live in a dangerously hot apartment, ignoring broken AC systems, or threatening you with eviction for trying to keep yourself cool, you do not have to fight them alone.
