    I have a lease until the end of February. I have windows that are broken and don’t lock, and I informed my landlord of this in September. The issue is still not fixed and I know that there is mold growing. I believe that I am able to break my lease due to the Warranty of Habitability and according to the law if I am living in an uninhabitable space I am able to breach my contract. Any fine details that I am missing?

      Hi Kelly,

      In cases where a property is not habitable, I believe the tenant can send a 3 days notice to remedy or quit (C.R.S. 13-40-104). Meaning, the tenant has to give the landlord an documented chance to fix the issue.

      However, the issue can’t be arguable. If there is some mold in the window sill, and a little bleach on a rag would clean it up, it’s hard to call that an issue of habitability. If there is obvious mold coming from inside the wall, then that’s a different story.

      A landlord does have a responsibility to ensure that the windows are secure, but as long as they aren’t fire exits, the landlord could simply nail them shut, and it would “fix” the problem – albeit it’s not the best solution.

      My point is that before you go announcing that your unit is “uninhabitable”, be sure that the majority of people in this world would agree with you, and that it’s not something you could easily fix. Judges usually see right through someone who is claiming that a unit is uninhabitable, but also conveniently got a job in another city at the same time – not that you’re doing that. I’m just saying.

      It you are serious about breaking your lease, I highly suggest you get legal advice from a lawyer before proceeding. I’m not a lawyer, so please don’t consider this as legal advice.

    You can walk out if you have a gas leak otherwise you must give the landlord written notice of the condition and a “reasonable” time to repair. You may not withhold the rent or he can begin eviction proceedings. If he doesn’t make the repairs, you may take him to court. However, if you or someone you invited in caused the damage to the windows which then resulted in the mold, the warranty of habitability does not apply. See section 38-12-505 of the Colorado revised statutes -available free through LexisNexis. Functioning windows are for sure covered by this as well as any condition that is materially dangerous or hazardous to your life, health or safety. He may also move you to another comparable unit and pay reasonable costs to do so.

  • Barb Forrest

    They can’t nail the windows shut. Working doors and windows is part of the statute.

    I am entering a lease just now, and the property has not yet been possessed. However, the rental agents did not tell us that the garage door did not have two working garage door openers until after the original possesion date.

    This issue, while it does not affect ‘habitability,’ is a material fact that was not disclosed by the owners or property management company.

    Is there a standard for ‘reasonable expectations’ for a garage? How many 2-car garages in the Denver Metro area do not have working garage door openers?

    I hope that I have a leg to stand on.


  • Barb Forrest

    I don’t think that’s required but the good news is, you can pick one up yourself. Just look on the motor and get the make and model number, some are remotes can be used with different makes.

    I do recommend making a list of everything lacking or broken at the property and sending your landlord a copy. That will give you some protection if later he claims he gave you two. Photos would be good too.

  • Jan B.

    It’s not that easy . . the property managers (PMs) had the current garage door opener evaluated.

    It is so old that the ‘new’ remotes need to be custom-calibrated to the proper radio frequency to work. The expense is somewhere close to the cost the range of purchasing a new door opener unit, which usually come with two openers. ‘They’ are ‘considering their options.

    tks for the suggestion,

    I’m renting out a room in my home on a month to month basis. A lease was never signed. How much notice is needed when I ask the tenant to leave, and what can I do if he doesn’t comply?

    Thank you.

    • Lucas Hall

      Hi Thomas,

      Check the “notices” section in the article above.

      If the tenant doesn’t vacate by the time lease ends, then you have to file an eviction lawsuit with your local courthouse. Then the sheriff will come to remove the tenant by force. You are not allowed to lock the tenant out.

    I’ve a few questions. If a water main is turned off due to a water main leak, wouldn’t the water in the whole neighborhood be out? Not just one house? NO WATER ALL DAY!!! Where do I go to the bathroom? Wash dishes? Brush my teeth? The leasing company claims that a water main is shut off due to a leak but will have a plumber out in the morning… pretty sure that a water main doesn’t service just one house.
    Also, if a house can’t handle running a 900 W microwave without tripping the breakers, would that be a fire hazard? I just microwaved a Boston Mkt dinner… I had to go out and reset the breaker FOUR times, plus, had to turn off the lights and unplug the refrigerator!!!
    Not to mention that there are no smoke detectors and no carbon monoxide detectors in the house… even though the lease states that both WILL be provided.
    Oh and, out of the 6 windows in this apartment, ONE opens. Fire hazard?

    • Lucas Hall

      Hi Corey,

      It’s nice to meet you.

      The “water main” usually refers to the main pipe that searches each house. Each house has a water main that can be shut off.

      Re: the microwave, I’m sure the house can handle it, but perhaps not on the current circuit that it’s plugged into. I have no idea if it could be a fire hazard. Usually the breakers do a good job of preventing an overloaded system. Try moving the microwave to another outlet, or reducing simultaneous usage of other heavy usage appliances when running the microwave.

      The landlord should provide and install smoke and CO detectors. No ifs ands or buts about it.

      Windows: I don’t know if it’s fire hazard as long as you have 2 forms of egress, but non-functioning windows can effect habitability.

      Keep in mind, I’m not a lawyer nor is this legal advice. I’m just a landlord trying to help :)
