LA's 82° cooling mandate
What owners & property managers need to know
Starting January 1, 2027, rental units in unincorporated LA County must be able to stay at or below 82°F. The City of Los Angeles is considering the same rule. For a lot of older buildings, the hard part isn't the AC unit. It's whether the electrical can run it.
What the 82° mandate actually requires
LA County's Safe Indoor Temperature Ordinance passed on August 12, 2025. It adds cooling to the basic habitability standards that already cover heat and hot water.
A temperature standard, not an AC law
Units must be able to stay at or below 82°F. How you get there is up to you: AC, fans, shades, window film, insulation or a mix.
Every habitable room
The standard applies to every habitable room, measured 3 feet off the floor in the center of the room.
Tenants can add their own cooling
Tenants may install portable or window AC, coolers, shades or film with 5 days’ written notice, as long as it’s code-compliant and needs no alterations. Landlords can’t block it or retaliate.
Enforced through complaints
Enforcement runs through the county’s Rental Housing Habitability Program, typically starting with a tenant complaint.
Phase-in for small landlords
As reported at passage, owners with 10 or fewer units must cool at least one room per unit by 2027 and the whole unit by January 2032.
Extensions are possible
Owners who can’t comply with portable or passive cooling can request an extension of up to two years from the county.
Does it apply to your building?
It depends on where the building is, not where you live. Here's where things stand as of November 2026.
| Location | Covered? | Notes |
|---|---|---|
| Unincorporated LA County | Yes | Starts January 1, 2027. Includes areas like East LA, Altadena, Marina del Rey and Ladera Heights. |
| Cities that adopt the county code | Yes | Only if the city formally adopts the ordinance. |
| City of Los Angeles | Not yet, pending | Council voted in February 2026 to explore opting in. Department reports were still outstanding in October 2026. |
| Santa Monica, Pasadena, Glendale, Burbank, West Hollywood and other cities | No | Not covered unless the city adopts its own rule. Worth watching. |
| Ventura County (Thousand Oaks, Westlake Village) | No | Outside LA County. |

Why your electrical system is the real question
Many LA apartment buildings were wired decades before anyone expected AC in every unit. Adding cooling without checking the electrical is how you end up with tripped breakers, melted outlets and angry tenants.
Small unit sub-panels
Older units often have small sub-panels with little room for new circuits. Zinsco, Federal Pacific and Challenger panels add an insurance problem on top.
Window and portable AC
They plug into existing outlets, often on circuits already shared with lights and appliances. Expect more tripped breakers and overheated receptacles.
Mini-splits and central AC
These usually need dedicated 240-volt circuits, and often a bigger unit panel or a building service upgrade.
Utility lead times
Service upgrades with LADWP or SCE take planning and scheduling. Waiting until a heat wave or a complaint makes it harder and more expensive.
A simple plan for owners and managers
- 1Confirm if you’re covered
Check whether each building is in unincorporated county or a city that has adopted the rule.
- 2Photograph panels and meters
The main service, the meter bank and a few unit panels tell us most of what we need.
- 3Get a capacity check
We’ll tell you what the building can carry today and which cooling options fit.
- 4Budget and phase the work
Combine cooling prep with any insurance-required panel replacements so the work gets done once.
How Branover helps
We've been upgrading LA apartment buildings since 1985. For cooling, that means:
- ✓ Capacity checks and load calculations, often from photos
- ✓ Dedicated circuits for window AC and mini-splits
- ✓ Unit sub-panel replacements, including insurance-flagged panels
- ✓ Building service upgrades and meter centers
- ✓ LADBS permits and LADWP or SCE coordination
- ✓ Work scheduled around tenants, unit by unit
82° mandate FAQ
Does the 82° mandate require air conditioning?
No. It sets a temperature standard. Owners can meet it with AC, fans, shades, insulation or other methods, as long as every habitable room can stay at or below 82°F.
Does it apply to my building in the City of Los Angeles?
Not yet. The City Council voted in February 2026 to explore adopting the county standard, but as of October 2026 no city ordinance had passed. Many owners are preparing anyway.
Can my tenants install their own AC?
Under the county ordinance, yes. Tenants can install portable or window units, coolers, shades or film with 5 days’ written notice, as long as the installation is code-compliant and doesn’t require alterations.
What if my building can’t handle the extra load?
That’s common in older buildings. The fix may be dedicated circuits, unit panel replacements or a service upgrade. The county also lets owners request an extension of up to two years if portable or passive cooling won’t work.
Who pays for the electricity to run the cooling?
The county ordinance doesn’t say. In most buildings, it follows whoever already pays the unit’s electric bill.
Can I pass the cost on to tenants?
In rent-stabilized units under the county ordinance, the cost of portable cooling devices can’t be passed through. Talk to your attorney or apartment association about other improvements.
