Colorado's Mold Law Explained: What Landlords and Tenants in Southern Colorado Must Know

If you rent your home in Southern Colorado — or you're a landlord with rental property in Pueblo, Colorado Springs, or anywhere else in our service area — there's a state law that changed the rules on mold and habitability, and a lot of people still don't know it exists. It's called Senate Bill 24-094, "Safe Housing for Residential Tenants," and it's been the law in Colorado since May 3, 2024. It rewrote Colorado's warranty of habitability statute (C.R.S. 38-12-503) and it puts hard deadlines on how fast a landlord has to respond when mold shows up.

We're not lawyers, and this isn't legal advice — for anything involving a dispute with a landlord or tenant, talk to an attorney or Colorado Legal Services. But as the IICRC-certified crew that gets called in to actually deal with the mold once the clock starts ticking, we think every renter and every landlord in Southern Colorado should understand what this law requires, because it changes how fast remediation needs to happen.

What the Law Actually Says

Colorado's warranty of habitability has always required landlords to keep rental housing fit to live in. SB24-094 made that promise a lot more specific when it comes to dampness and mold. Under the current version of 38-12-503, once a landlord has notice of mold associated with dampness in a unit — or any damp condition that could turn into mold — they're required to commence remedial action, and that remedial action has real teeth:

• Mitigating immediate risk — installing containment, stopping the active source of water, and installing HEPA filtration to cut down a tenant's mold exposure — must happen within 72 hours of the landlord receiving notice.
• The containment has to be maintained throughout the entire remediation and repair process, not just set up once and forgotten.
• The landlord has to take steps to prevent the mold or dampness from simply coming back.
• If the unit is genuinely uninhabitable, the tenant may be entitled to a comparable place to stay (or a hotel) and a prorated rent credit for the time they couldn't live there.
• Landlords also owe tenants written notice — things like an estimated timeline for when the work will be finished, and advance notice before anyone enters the unit to do the work.

That 72-hour number is the one worth remembering. It's not "get to it when you can" — it's a legal deadline for the mitigation steps, even if full repairs take longer.

Why This Matters More in Southern Colorado Than People Think

Our region doesn't have the reputation for mold that, say, a humid Gulf Coast city has — and for most of the year that's fair. But we see mold calls constantly, and they almost always trace back to the same handful of causes:

• A slow plumbing leak inside a wall or under a slab that nobody notices until the drywall starts to bubble or a musty smell shows up
• A basement or crawl space that took on water during a monsoon storm and didn't get fully dried out — Colorado's dry climate is deceptive because it can mask surface moisture while trapping it structurally
• A roof leak after a hailstorm that goes unnoticed in an attic for weeks
• Evaporative coolers ("swamp coolers"), common in older Pueblo and Colorado Springs homes, that leak or overflow into wall cavities

In a rental, any one of these can turn into a habitability dispute fast if the landlord doesn't act. And on the flip side, we've talked to plenty of landlords who genuinely want to do right by their tenants but don't know that Colorado now has a specific clock running the moment they're told about a mold problem.

What Landlords in Colorado Springs, Pueblo, and Beyond Should Do

If you own rental property anywhere in our service area — Pueblo, Colorado Springs, Cañon City, Trinidad, Pueblo West, Fountain, or the smaller towns around them — here's the practical version of compliance:

1. Put a system in place for tenant notices. If a tenant tells you about a leak, a damp spot, or a musty smell, that starts the clock. Document the date you received notice.
2. Have a restoration company you can call immediately, not one you have to shop for after the 72-hour window is already ticking. We get emergency calls from landlords specifically because they need containment and mitigation started same-day.
3. Don't just paint over it. A quick coat of Kilz over a mold spot doesn't satisfy "remedial action" under the law, and it definitely doesn't stop the mold from coming back — it just hides it until it's worse.
4. Get it inspected and documented. If a habitability dispute ever goes further, having a certified assessment of what was found, what was done, and when, is exactly the kind of paper trail that protects you.

What Tenants Should Do

If you're renting and you find mold or a damp, musty area of your home:

1. Put your notice in writing — a text or email to your landlord with a photo and the date is enough to start the legal clock. Verbal notice counts too, but written notice is easier to prove later.
2. Know the 72-hour number. If it's been well past that window with no containment or mitigation steps taken, that's worth raising directly with your landlord, and if it continues, worth a call to Colorado Legal Services or a tenant's rights organization.
3. Don't try to handle real mold growth yourself with bleach and a spray bottle. Small surface mold on a shower curtain is one thing; mold that's growing because of a hidden water source needs the source found and fixed, or it comes right back.
