Mold and Unsafe Housing: Where Tenants Can Report

Mold, water damage, pests, and unsafe wiring can affect your health and your home. Many tenants are unsure whether a problem is serious enough to report, or who to contact. The answer depends on the condition, the building, and where you live. This guide explains how to document the problem and identify the offices that may handle a complaint, so you can take the next step with confidence.

Recognize the problem and its source

Mold often appears where water has been present for a while, such as around windows, under sinks, in bathrooms, or on walls next to exterior surfaces. A musty smell, peeling paint, or dark spots can be signs. Water stains and ceiling sagging may point to a leak that needs to be fixed at the source. Painting or cleaning over the surface without fixing the water problem usually does not solve it.

Note what you see and smell, when it started, and whether it gets worse after rain or showers. A problem that returns after cleaning is important information to include in your report.

Document the condition

Take dated photos from several angles. Include a wide shot of the room and a close-up of the affected area. Keep a written log that lists each time you noticed the problem, each time you reported it, and each response from the landlord or manager. If you see a medical provider for symptoms you think are related, keep the visit papers and ask whether the provider can note the environment in the record.

Keep the original copies of your messages, emails, and letters. Avoid deleting anything, even if it seems minor, because it may show a pattern.

Notify the landlord in writing

Send a written notice that describes the problem, its location, and the date you first noticed it. Ask for an inspection and a repair by a specific date. Use the notice method your lease requires. If the lease is silent, use a method that creates a record, such as email or certified mail.

Be specific but calm. Avoid threats or guesses about causes. Stick to what you observed, what you did, and what you need.

Where tenants can report

Several offices may take a complaint, depending on where you live. A local housing or code enforcement office in your city or county often inspects rental housing conditions. Public health departments may also handle concerns about mold or hazards that affect health. If the situation is an immediate danger, such as a gas smell or exposed wiring, call the fire department or emergency services first.

Each state and locality has its own offices and procedures. The USAGov state governments directory can help you find official state websites, and your city or county government website will list local housing and code offices. Ask what documents to bring and how the inspection is scheduled.

What to expect from a complaint

After a complaint, an inspector may visit the unit, review photos, and write a report. Depending on the findings, the landlord may be ordered to make repairs within a set time. Inspections do not always cover every concern, so keep your own records even after a complaint is filed.

Filing a complaint is not the same as filing a lawsuit. It is a separate process with its own rules. Ask the office how the complaint will be handled and whether you will receive a copy of the report.

Health concerns and medical records

If you or someone in your home has health symptoms, talk with a medical provider about them. A provider can document symptoms and advise on next steps. Medical records may be useful if you later need to show the impact of the condition, but they are private. Share them only with people you trust and who need them for your matter.

When to talk to a lawyer

A lawyer can help if the landlord refuses repairs, if you face eviction or a rent increase after complaining, if a deposit is withheld for the problem, or if you are considering a claim for damages. A lawyer can compare your records with your state's habitability rules and explain the remedies available.

Ask about fees, whether the consultation includes a lease review, and how quickly the lawyer can respond. Get the terms in writing.

Free and low-cost help

The USAGov legal aid page explains how to find a lawyer and affordable legal aid. Legal aid offices often help tenants with unsafe housing and eviction defense for people who qualify by income. Some local tenant groups and community organizations also help tenants understand reporting options.

Questions to ask about unsafe housing

• Does my state require landlords to keep rentals safe and habitable?
• Which local office should receive my complaint?
• Is my documentation complete and organized by date?
• What protections apply if the landlord responds with an eviction or rent increase?
• Should I keep paying rent while the problem is pending, and how?
• Can I recover any costs, such as medical bills or damaged belongings?

Frequently asked questions

Is mold always a reason to move out?

Not always. The severity, the cause, and whether the landlord fixes it all matter. Get an inspection, document the problem, and talk with a lawyer before you decide.

Can I hire my own inspector?

You may be able to, but the results may not be accepted in a legal dispute by themselves. Ask a lawyer whether an independent report would help your situation.

What if the landlord blames me for the mold?

Dated photos, a written log, and your notice letters can show when the problem started and when you reported it. Keep everything.

Is it safe to clean mold myself?

Small areas may be cleaned with appropriate precautions, but large or recurring problems often need the water source fixed first. If you are unsure, ask the inspector or a professional before disturbing the material.
