What to Do When Your Apartment Has Mold or Is Unsafe

✓ Law Verified June 10, 2026

Apartment has mold — and you just found it on your wall, ceiling, or bathroom. Take a breath. This is a problem you can fix, and you have legal rights that protect you. Every state in the U.S. requires landlords to keep rental units safe and livable. Mold is a habitability issue. That means your landlord has a legal duty to deal with it. You do not have to just live with it.

The short answer: If your apartment has mold, document it immediately with photos and video, then send your landlord a written repair request by certified mail. In most states, your landlord must fix the problem within a set number of days — or you may be able to withhold rent, pay for repairs yourself and deduct the cost, or break your lease. Do not wait. Mold spreads fast, and so do your deadlines.

Is This Even Legal? Your Rights When Apartment Has Mold

When your apartment has mold, your landlord is likely violating something called the implied warranty of habitability. This legal rule exists in all 50 states. It means your landlord must keep your unit safe and fit to live in — even if your lease says nothing about repairs. Mold caused by leaks, poor ventilation, or building problems is the landlord’s responsibility, not yours.

However, the specific rules vary by state. Some states have mold-specific laws. Others handle mold under general repair and habitability codes. The table below shows how several states handle things when your apartment has mold.

State Notice Period Tenant Remedy Key Detail
California Reasonable time (case-by-case) Repair-and-deduct (capped at 1 month’s rent) Landlord must disclose known mold exceeding exposure limits (Civil Code § 1941.1)
Florida 20 days written notice Rent withholding after 20 days Notice must describe the mold problem specifically (FS § 83.201)
Massachusetts 5 days to start repairs; 14 days to finish Repair-and-deduct (capped at 1 month’s rent) State Sanitary Code requires units “free from excess moisture or mold”
Texas 7 days Repair-and-deduct only — no rent withholding allowed Mold over 25 sq ft requires a licensed remediator (Occ. Code Ch. 1958)
Maryland 45 days (effective Oct 1, 2026) Landlord must assess and remediate within 45 days New Mold Protection Act (SB 856) creates statewide mold standards

As a result, the steps you take depend on where you live. But in every state, you have the right to a mold-free home. The key is following the correct process.

What to Do Right Now (Step by Step)

If your apartment has mold, act quickly. Here is what to do today:

1. Document everything. Take clear photos and video of all mold you can see. Include close-ups and wide shots that show the room. Note the date. If you feel sick — headaches, coughing, breathing problems — write that down too. 2. Report it in writing. Send your landlord a written repair request. Use certified mail or email so you have proof.

Describe the mold, where it is, and how long it has been there. Ask for a specific repair date. 3. Check your state’s notice period. Your landlord typically gets a set number of days to respond. In Florida, for example, it is 20 days. In Massachusetts, repairs must start within 5 days.

In most states, you must give your landlord written notice and wait a specific number of days before you can withhold rent or use repair-and-deduct. If you skip this step, you may lose your legal protections. Send that written notice now — the clock starts when your landlord receives it.

4. Follow up. If the deadline passes and your landlord has not acted, you may be able to withhold rent, hire someone to fix it and deduct the cost, or contact your local housing inspector. In some states, you can break your lease entirely if the apartment has mold that makes it unlivable. However, always check your state’s specific rules before withholding rent.

How to Protect Yourself in Writing

When your apartment has mold, paperwork is your best weapon. Landlords sometimes claim they never knew about the problem. Written proof takes that excuse away. Every conversation about mold should be in writing — email, text, or certified letter.

Your written notice should include: the date, a description of the mold (location, size, color), any health symptoms you are experiencing, a request for repairs by a specific date, and a statement that you are aware of your rights under your state’s habitability laws. Keep a copy of everything you send. If you use certified mail, save the receipt and the return card. For example, in Texas, your landlord has 7 days to respond after receiving written notice. Without proof of delivery, you cannot prove the clock started.

Also keep a log. Write down every phone call, maintenance visit, and conversation. If your apartment has mold and your landlord ignores it, this log becomes evidence. Take new photos every week to show the mold spreading. Save any medical records if you get sick. Typically, tenants who keep detailed records get better results — whether in negotiations, in court, or with housing inspectors.

When to Get Help (Legal Aid or an Attorney)

Sometimes a written request is not enough. If your apartment has mold and your landlord refuses to fix it — or retaliates against you for complaining — it is time to get help. Contact a local legal-aid office or tenant attorney. Many provide free consultations, and some take habitability cases at no cost.

You should seek legal help immediately if: your landlord threatens to evict you after you reported the mold, the mold is causing serious health problems (especially for children, elderly people, or anyone with asthma), or if your apartment has mold so severe that entire rooms are unusable. In most cases, retaliation for reporting habitability problems is illegal. For example, New York’s Attorney General warns landlords that retaliatory actions can result in civil penalties of $1,000 to $10,000.

Frequently Asked Questions

Can I stop paying rent if my apartment has mold?

In many states, yes — but only after you follow the correct steps. You must send written notice first and wait the required number of days. In Florida, that is 20 days. In Texas, rent withholding is not allowed at all — you can only repair-and-deduct. Always check your state’s rules before withholding rent, or you may face eviction for nonpayment.

Can my landlord evict me for reporting mold?

No. In virtually every state, it is illegal for a landlord to retaliate against you for reporting a habitability problem. However, you need proof that you reported the mold in writing before the eviction notice arrived. That written record is what proves retaliation. If you receive an eviction notice after reporting mold, contact a local legal-aid office right away.

What if my apartment has mold but my landlord says it is my fault?

Landlords sometimes blame tenants for mold caused by “not ventilating enough.” In most cases, mold caused by building leaks, broken pipes, or poor construction is the landlord’s responsibility — regardless of your ventilation habits. If your landlord tries to blame you, document the source of the moisture. A housing inspector can determine whether the mold comes from a building defect or tenant behavior.

Bottom line: If your apartment has mold, you have rights — and real options. Document the problem, send written notice, and give your landlord the required time to fix it. If they do not act, you may be able to withhold rent, repair and deduct, or break your lease depending on your state. You do not have to accept an unsafe home. Check with a local legal-aid office if you need help navigating the process.
