Air conditioning is required in some states and cities, but not everywhere

Whether a landlord must provide air conditioning depends on where you live. Some states treat it as a basic utility that landlords must maintain if the building has it; others do not require it at all. A few cities — including Phoenix, Las Vegas, and parts of California — have passed local rules that make air conditioning mandatory during summer months. Most of the country has no such requirement, which means a landlord can legally rent an apartment without cooling as long as the lease does not promise it.

The key distinction is between states that set a habitability standard and those that do not. Habitability standards define what makes a rental legally livable — usually heat in winter, running water, and structural safety. If your state includes air conditioning in that standard, the landlord must provide it and keep it working. If it does not, the landlord has no legal obligation unless your lease specifically says otherwise.

Key Takeaways

  • Air conditioning is required by law in Arizona, Nevada, and some California jurisdictions, but most states do not mandate it.
  • If your lease promises air conditioning, the landlord must maintain it regardless of state law, and you can withhold rent or repair-and-deduct if they do not.
  • States that require it typically allow you to break the lease or reduce rent if the system fails and the landlord does not fix it within a set time.
  • In states without a requirement, your only recourse is the lease itself — read it carefully before signing to see what cooling, if any, is promised.

States and cities that require air conditioning

Arizona requires landlords to maintain air conditioning in all rental units during the cooling season (typically May through September). The law treats it the same as heat in winter — a basic habitability requirement. If the system breaks, the landlord must repair it within 48 hours in summer months, or the tenant can withhold rent or hire a repair person and deduct the cost.

Nevada has a similar rule: air conditioning must be maintained in working order, and landlords must repair failures within 24 hours during the cooling season. Las Vegas and Clark County have additional local ordinances that reinforce this requirement.

California does not have a statewide air conditioning requirement, but several cities have passed local rules. San Francisco, Los Angeles, and parts of the Bay Area require landlords to maintain cooling systems if they exist in the building. Some California jurisdictions also require landlords to install air conditioning in new construction or major renovations, though this varies by city.

A handful of other cities — including parts of New Mexico and Texas — have local ordinances requiring air conditioning, usually in response to extreme heat. Check your city or county website or contact your local housing authority to learn whether your area has a local rule.

What happens if your lease promises air conditioning

If your lease states that air conditioning is included, the landlord must provide and maintain it, even in states that do not legally require it. A promise in the lease is a contract, and breaking it gives you legal remedies. If the system fails and the landlord does not fix it within a reasonable time (usually 7 to 14 days, depending on the state), you have several options.

You can withhold rent until the repair is made, though you must follow your state's rules about how to do this — usually by notifying the landlord in writing and setting a important date. You can also use the repair-and-deduct remedy: hire a repair person yourself, pay for it, and deduct the cost from your next rent payment. Some states allow you to break the lease and move out if the landlord does not fix it within a certain period, usually 14 to 30 days.

Document everything: take photos of the broken unit, save repair quotes, and keep copies of all written communication with the landlord. If the landlord retaliates — raises rent, threatens eviction, or reduces services — after you report the problem, that is illegal in most states, and you may have a separate claim.

States with no air conditioning requirement

Most states do not require landlords to provide air conditioning. This includes much of the Midwest, Northeast, and South, where air conditioning was historically seen as a luxury rather than a necessity. In these states, a landlord can legally rent a unit without any cooling system, and the tenant has no legal recourse unless the lease promises it.

Even in states without a requirement, the lease controls. If you sign a lease that says "no air conditioning included" or is silent on the subject, you cannot later demand that the landlord install one. If the lease says air conditioning is included but does not specify what happens if it breaks, state law on habitability and repair timelines will fill in the gap.

Before you sign a lease in a state without an air conditioning requirement, ask whether cooling is included and get the answer in writing. If it is not, ask the landlord whether you are allowed to install a window unit or portable air conditioner at your own expense. Some leases forbid this, so clarify the rule before moving in.

How to check your state's habitability standard

Your state's landlord-tenant law is usually published online by the state attorney general's office or the state bar association. Search "[your state] landlord-tenant law" or "[your state] habitability" to find the official rules. Many states also have a housing authority or tenant rights organization that publishes a plain-language summary.

If you cannot find the answer online, call your local housing authority or a legal aid office — both can tell you whether air conditioning is required in your area and what your rights are if it fails. Some areas have a tenant union or housing rights hotline that answers these questions for free.

Your lease is also a source of information. Read the section on utilities and maintenance carefully. If it says the landlord will maintain air conditioning, that promise is binding even if state law does not require it. If it says nothing, you are in a state or city without a requirement, and you have no legal claim if the landlord does not provide cooling.

What to do if your air conditioning breaks

If your air conditioning fails and your lease or state law requires the landlord to maintain it, notify the landlord in writing when ready. Email is best because it creates a record. State the problem clearly — "the air conditioning unit is not cooling the apartment" — and ask for a repair date. Set a important date: "Please repair this by [date], which is [number] days from now."

If the landlord does not respond or misses the important date, send a second notice. In most states, if the landlord does not repair a required system within 7 to 14 days, you can hire a repair person yourself and deduct the cost from rent, or you can withhold rent. Before you do either, check your state's specific rules — some states require you to give the landlord a second chance or follow a specific notice procedure.

Keep all receipts, repair quotes, and copies of your notices. If the landlord retaliates or tries to evict you for reporting the problem, you will need this documentation to prove the timeline and that you acted in good faith.

Frequently Asked Questions

Can I break my lease if the air conditioning is broken and the landlord will not fix it?

In states that require air conditioning, yes — usually after the landlord has had 14 to 30 days to repair it. In states without a requirement, you can break the lease only if your lease specifically promises air conditioning and the landlord refuses to fix it. Check your state's landlord-tenant law or contact a legal aid office to learn the exact timeline and notice requirements.

What if my lease says air conditioning is not included?

If the lease explicitly states that air conditioning is not provided, the landlord has no obligation to install or maintain one, even in states that normally require it. You may be allowed to install a window unit or portable air conditioner at your own expense, but check the lease first — some prohibit this.

Is a broken air conditioner considered a habitability violation?

Only in states or cities that have made air conditioning a habitability requirement — Arizona, Nevada, and some California cities. In other states, a broken air conditioner is a breach of the lease only if the lease promises it. If your state does not require it and your lease does not promise it, the landlord has no legal obligation to fix it.

Can I withhold rent if the air conditioning is broken?

Yes, if your state requires air conditioning or your lease promises it and the landlord does not repair it within the required timeframe (usually 7 to 14 days). You must follow your state's specific procedure — usually written notice and a important date — or the withholding may not be legal. Contact a legal aid office or tenant rights organization to learn the exact steps in your state.

What if the air conditioning was working when I moved in but the landlord refuses to maintain it?

If the lease promises maintenance, the landlord must keep it in working order. If it breaks and the landlord refuses to fix it, follow the same steps as above: written notice, important date, and then repair-and-deduct or rent withholding if the landlord does not comply. If your state requires air conditioning, the landlord's refusal is a violation of state law, not just the lease.
