New Law Regarding Carbon Monoxide Detectors

Home Inspectors will start checking for CO detectors after passage of new Disclosure Laws

Bookmark and Share STAY UP TO DATE ON THIS IMPORTANT NEW LAW BY “LIKING” OUR FACEBOOK PAGE (Click above)

California Senate Bill 183 was signed into law to regulate the installation of Carbon Monoxide detectors. The law is a two-part law that requires an update to the Transfer Disclosure Statements used in a real estate transaction, and puts into law the Carbon Monoxide Poisoning Prevention Act of 2010.

The first part of the new law requires that as of July 1, 2011, Transfer Disclosure Statements (TD forms) include a line item regarding the presence or absence of a Carbon Monoxide detector in the same manner as Smoke Detectors, for all residential units that are sold. This applies to just about all types of occupancies from single family owner-occupied and rentals, to multi-family housing. If the property is being sold, it must now include a CO Detector if the dwelling has gas appliances, fireplaces, and/or attached garages as described below.

The second part of the law enacts the Carbon Monoxide Poisoning Prevention Act of 2010 which requires that all residential properties, not just those being sold, be equipped with a Carbon Monoxide detector when the property has a fossil fuel burning heater or appliance, fireplace, and/or an attached garage. All single-family homes in structures with 1-4 units (owner or tenant occupied) must be equipped with a detector on or before July 1, 2011.

All other multi-family residential units must be equipped with a detector on or before January 1, 2013, not just those being sold.

For rentals, the Carbon Monoxide detector must be operable at the time the tenant takes possession. A tenant is responsible for notifying the owner or owner’s agent if the tenant becomes aware of an inoperable or deficient carbon monoxide detector within his or her unit. The owner or owner’s agent must correct any reported deficiencies in the carbon monoxide detector and will not be in violation of this section for a deficient or inoperable carbon monoxide detector when he or she has not received notice of the deficiency or inoperability.

The bottom line is that ALL SINGLE FAMILY residential dwelling units as of July 1, 2011 must have a CO detector, even those that are not being sold. All other dewlling units (multi-family, dormatories, hotels, motels, etc) must have CO detectors installed by January 1, 2013.

Carbon Monoxide Detector

Carbon Monoxide Detector

Expect to see this new inspection item in your home inspection report. Home inspectors will be required to report on the presence or absence of a working Carbon Monoxide detector just like they report on Smoke Detectors, and water heater strapping.

Home Buyers and Sellers will also see this new requirement on Transfer Disclosure Statements. In addition to Smoke Alarms and strapped water heaters, sellers will be required to disclose the presence or absence of a working Carbon Monoxide detector starting July 1, 2011.

Details of SB 183

This bill requires that Transfer Disclosure Statements (TDS Forms) include a line items for Carbon Monoxide Detectors just like Smoke Detectors. This applies to homes intended for human occupancy that have a fossil fuel (gas or wood) burning appliance, fireplace, and/or an attached garage.

The remedy for failure to install a device is actual damages not to exceed $100, exclusive of any court costs and attorney’s fees. The Bill revises the statutory Real Estate Transfer Disclosure Statement to require the seller of a one-to-four residential property or manufactured home to make certain disclosures regarding carbon monoxide devices, smoke detectors, and water heaters, and requires the owner of a rental dwelling unit to maintain carbon monoxide devices in the unit (as of January 1, 2013).

Carbon Monoxide Poisoning Prevention Act of 2010

Details: As of July 1, 2011, Carbon Monoxide detectors will be REQUIRED in all houses (1 – 4 units) if they have any of the following:

  • Any gas appliances such as a gas stove, gas furnace, gas fireplace, gas water heater, etc.
  • A fireplace (even if it only burns wood, pellets, or any other material).
  • An attached garage (even if there are no gas appliances in the house!). Cars continue to emit CO even after they are shut off.
  • ANY rental dwelling that meets the criteria listed above. Yes this means that if you own a house, condo, or townhouse that you rent to another human being, you are REQUIRED to install Carbon Monoxide detectors.
  • As of January 1, 2013, ALL multi-family dwellings including multi-family dwellings that meet the criteria listed above will be required to have Carbon Monoxide detectors. Even those that are not being sold will be required to have them just like smoke detectors.

Be sure the home you are buying or selling is safe. A qualified home inspector will provide the information you need to feel confident about your home buying decision. Don’t compromise when choosing a home inspector. Be sure to ask if they will check for this.

You can read the entire new Carbon Monoxide Bill here.

The San Diego Real Estate Inspection Company feels that Carbon Monoxide detecors are as important, or more, than a traditional smoke detector. We will will add this as an inspection item effective immediately. We want to get this information out to buyers and sellers. Most Carbon Monoxide detectors cost $50 or less.

    This bill requires that a carbon monoxide device be installed in existing dwellings intended for human occupancy that have a fossil fuel burning appliance, fireplace, or an attached garage. So why are they required in rental if the rental unit has none of the above.

  6. pheller Says:

    December 9th, 2010 at 1:39 pm

    Hi Ken,

    They are only required in dwellings that have an attached garage or gas burning appliances. The requirement to install them kicks in on January 1, 2011 for houses being sold (with garage or gas appliances) or rentals (with garage or gas appliances), even if the rentals are not being sold.

    It will be required in all dwellings with a garage or gas appliances (including those that are not for sale) starting in 2013.

  7. s. Peroff Says:

    thank you

  8. pheller Says:

    January 15th, 2011 at 8:00 am

    Unfortunately the law does not specify installation requirements. You can follow the manufacturer’s instructions. Ideally you would install a CO detector near the furnace, and in each sleeping room.

    Not exactly. No one cares if you put one in your own house. Just like smoke detectors. You won’t be fined if you don’t have one.
    It is required as a safety device when you rent a house to someone, and when houses are transfered to a new owner.
    You also have a choice whether or not you want to take on the responsibility of owning a house/rental property or not.

    So, who is going to come to my house and check to see if I have a work CO detector installed in the dwelling that I own and occupy? What ever happened to private property rights?

  12. 49erDan Says:

    May 14th, 2011 at 5:45 pm

    I purchased a CO2 detector, the laws of physics show that CO2 is heaver than atmospheric air. So someone tell me why they recommend that the detector be installed high on a wall (not within 4″ from ceiling) instead of near the floor where CO2 hangs out?

  13. pheller Says:

    May 26th, 2011 at 4:49 am

    One small correction. It is CO, not CO2. And you are correct. I would buy the plug in units or mount them lower on the wall. I think that the manufacturers believe that when a forced air unit is on, the CO will be detected anywhere. However many people get poisoned because they use a heating source such as a BBQ or fireplace.

  14. pheller Says:

    May 26th, 2011 at 4:51 am

    No one. No one cares if you poison yourself. They are trying to get them into houses when they transfer ownership just like smoke detectors.

  15. Damon Salinas Says:

    June 3rd, 2011 at 8:50 am

    LOL @ “no one cares if you poison yourself”!! Im a property manager, I have heard a few different conflicting statements about what kind of CO detector is required. Does it have to be one with a battery back up AND wired? What if the house is not wired for it…?

  16. pheller Says:

    June 3rd, 2011 at 10:38 am

    It is my understanding that rental properties require hard-wired detectors.

  17. GettingBy Says:

    June 3rd, 2011 at 12:27 pm

    I don’t think existing construction requires hard-wired devices. New construction, yes. Just like smoke detectors.

  18. Cap Says:

    June 8th, 2011 at 7:20 pm

    Most people can see where this will go. My bet is that no two FD’s will require the same install
    requirements unless the State Fire Marshall already has published one. Think about it, CO is colorless, odorless and heavier than air and will settle in all low areas. Basements and multi-story homes may, by definition, require/need more units than a one story single family dwelling. In addition to bedroom locations, gas appliances are the primary targets of this legislation. Ignorance of other sources, since most are portable, will still get people….and their children, killed. Let’s educate in the schools as we regulate.

    Battery or hard wired? Either one is fine. Here is what the SB 183 itself says:

    (a) “Carbon monoxide device” means a device that meets all of the
    following requirements:
    (1) A device designed to detect carbon monoxide and produce a distinct,
    audible alarm.
    (2) A device that is battery powered, a plug-in device with battery backup,
    or a device installed as recommended by Standard 720 of the National Fire
    Protection Association that is either wired into the alternating current power
    line of the dwelling unit with a secondary battery backup or connected to a
    system via a panel.”

    Some statements in this article conflict with what I see in the SB 183 and the Cal Fire news release. The references below state that CO detectors are required in *ALL* single family home July 1, 2011, whether being sold or not.

    From http://www.leginfo.ca.gov/pub/09-10/bill/sen/sb_0151-0200/sb_183_bill_20100507_chaptered.pdf

    “[...]in each existing dwelling unit having a fossil fuel burning heater or appliance, fireplace, or an attached garage, within the earliest applicable time period as follows:
    (1) For all existing single-family dwelling units intended for human occupancy on or before July 1, 2011.
    (2) For all other existing dwelling units intended for human occupancy on or before January 1, 2013.

    From http://www.fire.ca.gov/communications/downloads/newsreleases/2011/CarbonMonoxideDetectors.pdf

    Though previous laws only required newly-constructed homes to have CO alarms, the state’s new Carbon
    Monoxide Poisoning Prevention Act (Senate Bill 183) requires owners of all existing single-family homes with an attached garage or a fossil fuel source to install CO alarm devices within the home by July 1, 2011. Owners of multi-family leased or rental dwellings, such as apartment buildings, have until January 1, 2013 to comply with the law.

    As a lender I can see this having a significant impact on getting homes sold short term. I spoke with an appraiser who said that even though HUD hasn’t issued a Mortgagee Letter on the topic, it’s his opinion it will have to be addressed on all appraisals after July 1.
    I wonder how long it will take the real estate community to get their brains around it. The only sellers are banks, who will now have an additional expense and we know how happy that makes them
    and short sale sellers,most who have mentally checked out and won’t be willing to make the investment.
    It would be great if you could provide the code so the video could be shared.

    Previous poster was mistaken: Carbon Monoxide is lighter than air, not heavier.

    C=12
    O=16

    O2 (Oxygen) = 16*2
    N2 (Nitrogen) = 14*2

    So, Carbon Monoxide is slightly lighter than Oxygen, and the same as Nitrogen. Thus it is lighter than air.

  30. George Stebbins Says:

    June 28th, 2011 at 5:34 pm

    In case that wasn’t clear, CO has a molecular weight of 12+16=28. Oxygen has a molecular weight of 16*2 = 32. Nitrogen has a molecular weight of 14*2 = 28.

    CO = 28
    O2 = 32
    N2 = 28

You mean to tell me that someone working for the State is going to come to my house and demand I let the in to check to see if I have a CO dector? What if I refuse to let them in? Did anyone think about that? The Constitution protects us from an intrusive Government. Or are you simply going to follow blindly like sheep?

    Wait a minute! 400 deaths a year! Nationally! And the number quoted in California is 30 to 40 deaths a year.

    What special interest group pushed this garbage through the legislature?

    Let’s see, there are approximately 35 million people in California; average 4 people per household; say 60% live in single-family homes. That is over 5.25 million homes. Say one-third of those are two-story requiring one sensor per floor — that is 7 million detectors. At an average cost of $35 per detector, that is $245 million.

    I can think of no other cause of death that has a lower yearly mortality rate than carbon monoxide poisoning. Yet in these hard economic times, the legislature is going to force Californians to shell out $245 million to save 30 to 40 lives per year. Moreover, that does not even count dorms, condos, and all the rest that were given a reprieve. Wonder how many of those deaths occur in dorms, condos and all those other non-single family dwellings?

    No wonder this State is broke as the legislature wastes huge amounts of our money to benefit the least number of people! Pardon me, but I have to call my broker and tell him to invest heavily in companies making carbon monoxide detectors.

    Let me clear up a few misconceptions here. First we are “talking” about Carbon Monoxide CO and not Carbon Dioxide CO2. Carbon Monoxide is highly poisonous like cyanide (HCN, K+CN-, Na+CN-), odorless, colorless but less dense (lighter) than air, 1.145 @ 25oC. CO is the product of incomplete combustion. Carbon Dioxide is odorless, colorless and rather heavier than air, 1.977 @ 0oC. Air has a density of 1.184 @ 25oC. Carbion dioxide is what animals breathe out. It is also what plants take in and use photosynthesis for to make sugar. So CO would tend to be present near the ceiling, CO2 on the floor. But these are gases so they do eventually diffuse and mix with air to become “even” throughout a building or vehicle.

  36. Ron B Says:

    July 7th, 2011 at 12:29 pm

    Clearly Californian Senators need to get their priorities straight; the main business of the Senate should be preparing a balanced budget and passing legislation that will reduce the size and impact of our government. The review and elimination of State agencies and commissions as well as the reduction of civil codes should then be your next concern.

    One might wonder if the senators have any financial interests in the companies that produce CO2 detectors. We should be free to decide what we have in our private residences!

    Lets see… There are aprox 37,000,000 people in Calif. If 30-40 die or get sick each year from Carbon Mono, then its calculated at aprox .00001% of the population get sick or die each year from Carbon Monoxide. Hmmm we had better ask our selves who is getting the money for these damn things! Perhaps we should throw these things into the harbour…

  44. Jarhead Says:

    August 25th, 2011 at 10:38 am

    Here’s the way it works, people: The manufacturers of carbon monoxide detectors see that they can make millions and millions of dollars if a law were to be passed requiring every home owner in the state (and other states for that matter) to purchase a CO detector. The manufacturers get their lobbyists to grease the palms of our corrupt politicians, and explain that the state will also benefit by the millions of dollars in revenue from the sales tax. Before you know it, a law is passed. Samething with hands-free devices for our cell phones. Sometimes the reverse happens. The politicians see an opportunity to get pay-offs, so they contact the lobbyist of the manufacturers to propose their idea and arrange the bribes. That’s why lobbyist must be registered with the state – so the politicians can identify them and the industry they represent.

    The law states that a title transfer for a property is not dependent on the installation of a CO moniter as is required for a water heaters and smoke detectors…. yet says there can be damages up to $100 plus court and attorney costs for no CO detector… Does this mean that a seller can sell and home and transfer title but can later get sued for the lack of a CO detector.

  47. pheller Says:

    September 18th, 2011 at 9:21 am

    The number of detectors is not specifically defined in the bill. To comply at the bare minimum, at least one should go in the hallway outside of each cluster of bedrooms. If all bedrooms are connected to one hallway, then isntall one. If the rooms are on separate ends of the house, or on different levels, then one per level is needed. For maximum safety, install one in each sleeping room in addition to the minimum. All detectors have manufacturer’s recommendations on the packaging. Please check this and apply toyour particular situation.

  49. pheller Says:

    September 29th, 2011 at 10:01 am

    It is the home owner’s responsibility to install a CO detector. If you are the seller, you need to pay for it and install it. And no, you cannot sue or break the contract with your agent because they didn’t install one. They ‘should’ advise you to install one if you are the seller, but it is not their responsibility to do so. It is the home owner’s responsibility.

    I received my notice in the mail today. I already installed one upstairs and one in my attached apartment downstairs. They cost between $20-$35.00. My beef is that the law was passed May 2010, detectors must be in all homes by July 2011 and they wait until Friday, Oct. 14 to send out notices to frighten seniors, the disabled and all the rest of the population of California to comply by Oct. 31 or you will be fined. Oh, they do want to help. Just send them $76.00!!!!!! and they will send you one detector. So this is how they will balance the budget. Make a profit of $40.00 on every detector they force feed to a frightened public. Well, they got this letter too.

    December 23rd, 2011 at 10:19 pm

    Let me play devils advocate… The amount of deaths and poisoning stats are only the ones that are reported.Lots of elderly deaths that are unexplained are more likely CO, but are chalked up to old age.On the other hand, if you are going to buy a CO monitor be careful. Regular monitors allow 70 parts per million for up to 4hours before they alarm. if you read the manual they also state that they are not sufficient to protect infant children or elderly. In my opinion the law is a half ass attept to save anyone,it requires a safety device, but the device itself is insufficient.
