Toxic Mold

How to Report Mold to the Los Angeles Housing Department

What follows are my own general observations and opinions. This is not legal advice, and procedures at any agency can change, so I would confirm current requirements directly with the agency before relying on anything here.

When a landlord ignores a mold complaint, one of the first things I generally suggest a tenant consider is bringing in a housing inspector. In my experience this single step changes more cases than almost anything else a tenant can do on their own, and it costs nothing.

Why I think an inspection matters so much

Up to that point, a dispute is usually one person’s word against another’s. The tenant says there is mold and a leak; the landlord says it is minor, or cosmetic, or the tenant’s fault for not opening a window.

An inspector changes that dynamic in two ways, as I see it. First, many landlords who have ignored months of texts respond quickly once a government agency is involved. Second, and more importantly in my view, it creates documentation from a neutral source. When a case is later evaluated, an official record generally carries weight that a tenant’s own photographs, however good, cannot fully replicate.

There is also a legal dimension worth understanding. As I read Civil Code section 1942.4, an inspector’s notice is one of the elements that can affect a landlord’s ability to demand or collect rent where serious conditions go unrepaired. That is a meaningful consequence, and it generally cannot happen without official involvement.

Who to contact in Los Angeles

If your rental is within the City of Los Angeles, habitability complaints generally go to the Los Angeles Housing Department, which handles code enforcement for residential rental property. The City’s 311 service is the usual entry point for reporting, and LAHD also takes complaints directly.

If you are outside city limits, the agency differs. Unincorporated Los Angeles County areas and separate cities such as Santa Monica, Beverly Hills, Culver City, Long Beach and Inglewood each have their own code enforcement or housing departments. In my experience tenants sometimes lose weeks by filing with the wrong agency, so it is worth confirming which one covers your address before you start.

What I suggest doing before you file

My strong view is that you should give the landlord written notice first, if you have not already. Beyond being sensible, notice is what establishes that the landlord knew about the problem, and that knowledge tends to matter in every later step.

I would also prepare before the inspector arrives:

  • Dated photographs and video of every affected area, including inside closets and under sinks where problems often start.
  • A written timeline of when you first noticed the issue, when you reported it, and what response you received.
  • Copies of your texts and emails with the landlord or property manager.
  • A list of every affected room, so nothing gets missed during a walkthrough.

In my experience inspections are often shorter than tenants expect. Being organized changes what gets recorded.

What generally happens next

An inspector typically visits, documents conditions, and where violations are found, issues an order requiring the owner to correct them within a set timeframe. There is usually a re-inspection to confirm compliance.

I want to set realistic expectations here. Inspectors are enforcing housing codes, not representing you. They do not recover money for you, they do not address your damaged belongings or medical costs, and in my experience their findings sometimes describe conditions more conservatively than a tenant would. The inspection is a foundation, not a remedy.

I would also ask for a copy of any report or notice issued. Do not assume it will be sent to you automatically.

If nothing changes

Some owners comply quickly. Others do the minimum, or paint over the problem again. If conditions persist after an inspection and an order, my general view is that the tenant’s position is considerably stronger than it was before, because there is now an official record that the condition existed and was not corrected.

That is usually the point at which I think it makes sense to talk seriously about civil remedies.

A word about retaliation

Many tenants hesitate because they worry that calling the city invites eviction. Civil Code section 1942.5 addresses retaliation against tenants for asserting habitability rights within a protected period. My honest observation is that retaliation, when it does occur, tends to strengthen a tenant’s overall position rather than weaken it. But if you receive any notice after filing a complaint, treat it as urgent, because eviction timelines in California move quickly.

To repeat: these are my general opinions and impressions, not legal advice, and reading this does not create an attorney-client relationship.

My apartment had mold and management was dragging their feet to resolve it, and completely mishandling the situation. Then I retained Alex and long story short, I was able to hold management accountable and collect a sizeable settlement. Alex was professional, responsive, and most importantly he didn’t oversell or over promise a settlement number. He was really easy to work with and he went toe to toe with the insurance adjuster when they tried to delay the process with last minute changes. I’d recommended Alex to friends, family and internet strangers, LOL. He’s someone you need on your side.

I had a great experience working with Mehdipour Law to resolve an issue with a tenant. From start to finish, he was incredibly helpful, providing clear guidance and actionable next steps throughout the entire process. What really stood out was his attention to detail and ongoing support—he even checked in afterward to follow up and make sure everything was completely taken care of. If you need a reliable, proactive, and attentive attorney, I highly recommend Mehdipour Law, PC.

Amazing experience with Alex. We were in a last minute contractual bind and needed additional protection, as the docs we started to receive were very complex and lengthy. Alex was super responsive and extremely quick. He simplified item, that we didn’t understand, to make sense to us. And he provided amazing advice. Our deal moved forward, with countless protections added to our side. We feel very grateful for this and highly recommend him. Thanks so much Alex!

Alex has been a huge help as we work through a difficult tenant situation. He has gone above and beyond and has treated the issue with the same care and attention he would give his own. His guidance has been incredibly valuable, and he is always willing to answer questions, whether they are directly related to the case or not. Working with Alex feels like having a trusted legal advisor on call. He is responsive, dedicated, and focused on actually moving things forward. He is not the kind of attorney who just runs up the bill without getting results. We truly appreciate everything he has done and highly recommend him.
