The Carbon Monoxide Detector Notice (C.A.R. Form CMD) is a real estate notice used in California to provide parties with information about state and possible local requirements to install carbon monoxide detectors in residential dwellings. It summarizes when detectors are required, key exceptions, and potential fines or damages for noncompliance. The form is typically acknowledged by signature to document that the buyer/tenant and seller/landlord received the notice, helping reduce disputes and clarify responsibilities during a sale or lease.

The AI checks your answers before you download

16 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Property Address is present and sufficiently complete

Validate that the Property Address field is not blank and contains enough components to identify the property (e.g., street number, street name, city, state, and ZIP when applicable). This is critical because the notice must be tied to a specific dwelling unit for compliance and recordkeeping. If the address is missing or too vague (e.g., only a city), the submission should be rejected or routed for correction.

Property Address format and character validation

Check that the address uses valid characters (letters, numbers, spaces, and common punctuation like commas, periods, and hyphens) and does not contain corrupted OCR artifacts or random symbols. This reduces downstream issues in indexing, matching, and audit trails. If invalid characters or obvious OCR noise is detected, flag the record for manual review and request a corrected entry.

Seller/Landlord signature presence (Party 1)

Ensure the first Seller/Landlord signature field is completed (e-signature captured or wet signature indicator present). The notice requires acknowledgment of receipt, and missing signatures undermine enforceability and compliance documentation. If absent, the system should block completion or mark the form as incomplete.

Seller/Landlord printed name presence and consistency (Party 1)

Validate that the printed name for Seller/Landlord (Party 1) is present and appears to be a person or entity name (not a phone number, address, or stray text). This is important for identifying who acknowledged receipt and for later dispute resolution. If missing or clearly not a name, the submission should fail validation and require correction.

Seller/Landlord date format and validity (Party 1)

Verify that the Seller/Landlord date is provided and matches an accepted date format (e.g., MM/DD/YYYY) and is a real calendar date. Dates are essential to establish when the notice was acknowledged and to support transaction timelines. If the date is missing, malformed, or impossible (e.g., 13/40/2026), the form should be rejected or flagged for correction.

Buyer/Tenant signature presence (Party 1)

Ensure the first Buyer/Tenant signature field is completed. The form states the undersigned acknowledge receipt, and buyer/tenant acknowledgment is a core purpose of the notice. If the signature is missing, the system should prevent finalization or mark the document as non-compliant.

  • Buyer/Tenant printed name presence and consistency (Party 1)
  • Buyer/Tenant date format and validity (Party 1)
  • Second Seller/Landlord block completeness (if any field is populated)
  • Second Buyer/Tenant block completeness (if any field is populated)
  • Signature-date logical consistency per signer
  • Cross-party date consistency (acknowledgment timing)
  • Broker/Company information field validation (if captured)
  • Phone and fax number format validation (if provided)
  • Document type and version identification check (CMD 4/12)

How to Fill Out C.A.R. CMD Online for Free in 2026

What the AI walks you through.

  1. Enter the property address for the dwelling covered by the notice.
  2. Review the installation requirements section to understand when carbon monoxide detectors are required and the general placement standards.
  3. Review the exceptions section to determine whether the property may be exempt based on fuel-burning appliances, fireplaces, attached garage, or government ownership/lease.
  4. Review the disclosure and compliance sections, including potential penalties and the recommendation to consult inspectors/contractors or local building departments.
  5. Check local city/county point-of-sale or retrofit requirements that may apply to the property transfer or lease.
  6. Collect signatures, printed names, and dates from all applicable parties (seller/landlord and buyer/tenant, including additional signature lines if needed) to acknowledge receipt.

Common Mistakes in Completing C.A.R. CMD

The ones the AI is built to catch.

Leaving the Property Address blank or incomplete
People often forget to fill in the property address because the form reads like a notice rather than an input-heavy document. An incomplete address (missing unit number, city, or ZIP) can make the acknowledgment hard to tie to the correct transaction or dwelling unit. Always enter the full street address, unit/apartment number (if any), city, state, and ZIP exactly as shown on the purchase/lease agreement.
Using the wrong party role (Seller/Landlord vs. Buyer/Tenant)
This form is used for both sales and rentals, so signers sometimes choose the wrong signature line or assume only one side must sign. If the wrong role signs (e.g., a tenant signs on a buyer line), the acknowledgment may be questioned or rejected by a broker/transaction coordinator. Confirm whether the transaction is a sale or a lease and have each person sign on the correct labeled line for their role.
Missing dates next to signatures
Signers frequently add signatures but skip the date fields, especially when signing electronically or in a hurry. Undated acknowledgments can create compliance gaps in the file and may trigger follow-up requests during escrow or property management onboarding. Date every signature with the actual signing date (month/day/year) and ensure it matches the timeline of the transaction documents.
Not printing names legibly (or leaving Print Name blank)
Because there is a separate “Print Name” line, people often assume the signature alone is enough or they write something illegible. Illegible or missing printed names can make it unclear who acknowledged receipt, especially when multiple parties have similar signatures. Always print the full legal name clearly (first, middle/initial if used, last) exactly as it appears on the contract.
Forgetting additional signers (multiple sellers/buyers/tenants)
The form provides two lines for each side, but transactions can involve more than two sellers, buyers, or tenants. When not everyone signs, the file may be incomplete and a party can later claim they never received the notice. Ensure every adult party on title/contract (or every tenant required by the lease) signs; if more lines are needed, attach an addendum or additional signature page referencing the property address and form name.
Assuming the notice itself is the disclosure of detector presence
A common misunderstanding is thinking this notice confirms whether detectors are installed, when it mainly explains legal requirements and acknowledges receipt. This can lead sellers/landlords to skip the actual disclosure required on the TDS/MHTDS (Section II A) for 1–4 residential sales. Use this form as an acknowledgment only, and separately complete the required disclosure forms to state whether carbon monoxide detectors are present.
Misapplying the 'exceptions' and claiming an exemption incorrectly
People often read the exceptions quickly and assume they are exempt without verifying whether the property has a fossil-fuel appliance, fireplace, or attached garage. Incorrectly claiming an exemption can lead to noncompliance, potential fines after notice, and disputes after transfer. Verify the property features (heater type, appliances, fireplace, garage attachment) and, when unsure, confirm with a home inspector or local building department.
Confusing state requirements with local point-of-sale/retrofit rules
Because the form mentions statewide rules and also warns about local requirements, signers sometimes assume state law is the only standard. This can cause last-minute delays if a city/county requires installation before transfer or has stricter placement rules. Check the specific city/county building and safety department requirements early and document compliance before closing or move-in.
Not specifying detector placement compliance (assuming 'installed somewhere' is enough)
Owners sometimes believe that having a single detector anywhere in the home satisfies the requirement, overlooking minimum placement rules (outside each sleeping area and on each floor in multi-level dwellings). Improper placement can still be treated as noncompliance and may be flagged by inspectors or local enforcement. Follow the state building code minimums, manufacturer instructions, and any stricter local standards; when in doubt, have a qualified professional confirm placement.
Broker/office information inserted into blank areas instead of required fields
In some transaction software, company details (broker name, address, phone/fax) can auto-populate into open spaces, while required fields like the property address or party names remain incomplete. This creates a form that looks “filled out” but lacks the key identifiers and acknowledgments needed for the transaction file. Review the final PDF for required fields (property address, signatures, printed names, dates) and do not rely on auto-fill blocks to satisfy form requirements.

What is the Carbon Monoxide Detector Notice (C.A.R. Form CMD) used for?
It is a written notice that explains California’s carbon monoxide (CO) detector installation requirements and confirms the parties received the notice. It is commonly provided in real estate sales and leases.
Who should sign this form?
The form includes signature lines for the Seller/Landlord and the Buyer/Tenant. Each person signing is acknowledging receipt of the notice.
Does signing this form mean the property already has carbon monoxide detectors installed?
No. The form is primarily a notice and receipt acknowledgment; it does not certify that detectors are installed or properly placed.
Which properties in California are required to have carbon monoxide detectors?
As of July 1, 2011, existing single-family dwellings must have CO detectors, and by January 1, 2013, most other dwelling units intended for human occupancy (e.g., apartments, condos, hotels, dorms) must have them. The requirement applies broadly to owners of dwellings.
Are there any exceptions where carbon monoxide detectors are not required?
Yes. The law does not apply if the dwelling unit has none of the following: a fossil-fuel-burning heater/appliance, a fireplace, or an attached garage. It also does not apply to units owned or leased by certain government entities listed in the notice.
Is there an exemption for REO (bank-owned) properties?
No. The notice states there is no exemption for REO properties, and the installation requirement applies to all owners (individuals, banks, corporations, and other entities).
Where do carbon monoxide detectors need to be installed?
At a minimum, state building code requires placement outside of each sleeping area and on each floor in a multi-level dwelling. Additional or different requirements may apply based on local standards and the manufacturer’s instructions.
Does California law require the seller to disclose whether CO detectors exist in the home?
The notice states the Health and Safety Code does not require a separate disclosure about the existence of CO detectors. However, sellers of residential 1–4 property who complete a Transfer Disclosure Statement (TDS) (or MHTDS for manufactured/mobile homes) must disclose in that form whether the dwelling has a CO detector.
What happens if an owner does not install carbon monoxide detectors when required?
If an owner continues to fail to install detectors after notice by a governmental agency, they could be fined up to $200 per violation. The notice also states a seller/owner could be subject to damages up to $100 plus court costs and attorney fees.
Can a property sale be invalidated if the seller did not install required CO detectors?
No. The notice states the transfer will not be invalidated, but the seller/owner may still face potential damages and other consequences described in the form.
Do local city or county rules ever require CO detectors before closing or at “point of sale”?
Yes. The notice warns that some localities have their own retrofit or point-of-sale requirements that may require installation before a property transfer, so parties should check with the local building and safety department.
What should a buyer or tenant do if they are unsure whether detectors are installed correctly?
The notice advises buyers to consult a professional of their choosing (such as a home inspector, contractor, or building department) to confirm whether detectors are installed as required and to determine proper placement.
What information needs to be filled in on this form?
Typically, the property address and the names, signatures, and dates for the Seller/Landlord and Buyer/Tenant are completed. The form itself provides the legal notice language; it is not a checklist of detector locations.
How and when is this form usually delivered or submitted?
This form is generally provided as part of a real estate transaction or lease paperwork and kept in the transaction file. It is not described as something you submit to a state agency; it serves as documentation that the notice was received.
