Yes. In California, landlords have to provide window screens and keep them in working order. The rule lives in Title 25 of the California Code of Regulations, Section 728, which requires insect screening on every openable window in rooms used for living, dining, cooking, sleeping, bathing, and toilet facilities.1Legal Information Institute. California Code of Regulations Title 25, Section 728 – Insect Screening Most tenants look for the requirement in Civil Code Section 1941.1, the habitability statute, and don’t find screens listed there by name. That’s why landlords sometimes claim the duty doesn’t exist. It does. The authority is just in the regulations rather than the Civil Code.
What the Screen Rule Actually Covers
Section 728 applies to every openable window in a habitable room and in bathrooms. The screening has to be “properly maintained,” which means intact mesh, a frame that fits, and hardware that holds it in place.1Legal Information Institute. California Code of Regulations Title 25, Section 728 – Insect Screening The same regulation reaches exterior doors serving those rooms: they need either a screen door or a solid door with a self-closing device.
The rule connects to the broader habitability framework through the Health and Safety Code. Civil Code 1941.1 treats a unit as untenantable if it meets the substandard conditions listed in Health and Safety Code Section 17920.3, which includes the harboring of insects and inadequate sanitation.2California Legislative Information. California Health and Safety Code Section 17920.3 A window that opens to the outside without a screen is the textbook entry point for mosquitoes and flies, which is why the state treats missing screens as a public-health matter rather than a cosmetic one.
When the Damage Is Yours to Fix
The screens have to be there and functional when you move in. After that, your own conduct matters. Civil Code Section 1941.2 requires tenants to keep the unit clean, use fixtures properly, and avoid willfully damaging the dwelling or its equipment. If your dog claws through the mesh or a screen gets bent because someone forced it, the repair is on you.
Normal aging is different. Sun-brittle mesh, warped frames, and corroded hardware remain the landlord’s responsibility. The line between wear and tenant damage is where most deposit fights happen, so document every screen at move-in with dated photos. Note any tears, dents, or missing screens on the inspection checklist before signing. That record is your defense later.
How to Ask for the Repair
Put the request in writing. Identify the window, describe what’s wrong with the screen, and date the letter. California’s Department of Real Estate recommends sending it certified mail with return receipt, or delivering it in person against a dated receipt.3Department of Real Estate. Landlords’ and Tenants’ Rights Guide – Dealing With Problems Keep a copy for yourself.
California presumes 30 days is a reasonable amount of time for non-emergency repairs.3Department of Real Estate. Landlords’ and Tenants’ Rights Guide – Dealing With Problems For a screen, that’s more than enough. Photograph the problem when you send the notice, and photograph it again after the 30 days if nothing has changed.
If Your Landlord Ignores You
Civil Code Section 1942 lets you fix the problem yourself and take the cost off your next rent payment.4California Legislative Information. California Civil Code Section 1942 The limits on this remedy are firm:
- The repair cost cannot exceed one month’s rent.
- You can only use repair-and-deduct twice in any 12-month period.
- The remedy is unavailable if you or your household caused the damage.
- You must have given the landlord notice and a reasonable time to act first.
A screen replacement almost always comes in well under a month’s rent, so this is the practical route. Have a repair company do the work, keep the receipt, attach a copy to your next rent check, and deduct the amount.
Withholding rent entirely is a different remedy, and a riskier one. California courts recognize it for serious habitability violations, but the state Department of Justice warns that withholding rent “may put you at risk of eviction” and recommends legal advice before trying it.5California Department of Justice. Know Your Rights – Habitability For a missing screen, repair-and-deduct is the safer tool.
You can also file a complaint with your local code enforcement or building inspection office. Once a public enforcement officer formally notifies a landlord of substandard conditions, Civil Code Section 1942.4 blocks that landlord from demanding rent, collecting rent, or serving a pay-or-quit notice until the conditions are corrected.6California Legislative Information. California Civil Code Section 1942.4 That’s real financial pressure, and it tends to move things quickly.
Retaliation Is Illegal
Tenants often hesitate to ask for repairs because they’re afraid of being pushed out. Civil Code Section 1942.5 addresses that directly. For 180 days after you send a repair notice, file a complaint with a government agency, or an inspection produces a citation, your landlord cannot evict you, raise your rent, or cut services in response.7California Legislative Information. California Civil Code Section 1942.5
If they do it anyway, you can sue for actual damages plus punitive damages of $100 to $2,000 per retaliatory act where the landlord acted with fraud, oppression, or malice.7California Legislative Information. California Civil Code Section 1942.5 A lease clause that tries to waive this protection is void.
“As-Is” Lease Language Doesn’t Help the Landlord
A clause saying you accept the unit “as-is” or waive habitability doesn’t hold up in California. The implied warranty of habitability is a legal duty that exists no matter what the lease says, and courts have consistently refused to let landlords contract out of it.8Loyola University Chicago Law Journal. Non-Waiver of the Implied Warranty of Habitability in Residential Leases The anti-retaliation rules are also non-waivable as a matter of public policy.7California Legislative Information. California Civil Code Section 1942.5 If a landlord points to lease language to avoid installing or repairing screens, the law backs you, not them.
One Thing Screens Aren’t For
An insect screen is meant to keep bugs out. It is not built to stop a child from falling through an open window. The Consumer Product Safety Commission puts it plainly: “Never depend on screens to keep children from falling out of windows.”9CPSC.gov. Publication 5124 – Preventing Window Falls If you have young children, window guards or opening-control devices meeting ASTM F2090 are the actual fall-prevention hardware, and some California cities require landlords to install them on request. That is a separate issue from the screening requirement, but worth knowing before you rely on a screen for something it cannot do.
