First-time instructions

These instructions detail what information you need to enter when you register for the first time.

Registry requirement

As a landlord you must ensure that your property is in compliance with local, state and federal housing laws and regulations. In January 2019, the Marin County Board of Supervisors approved a Just Cause for Eviction ordinance (Marin County Municipal Code Chapter 5.100). 

This ordinance established a rental registry and requires properties subject to the ordinance to register units with the County’s Rental Registry and update annually. Step-by-step instructions are provided below. Section 5.100.040(a) provides more details on all required prerequisites to terminate. 

Steps

  1. Gathering information

    We recommend gathering all related documents and information before beginning the registry. The registry will call for:

    First time registering

    Click on the Register link at the bottom of the screen. This will prompt you to fill out your landlord/property manager information. You will receive a Landlord ID to the email that you enter on this page. Once you have received your Landlord ID, you will receive a subsequent email with a verification code to complete your login.

    Please allow several minutes to receive emails from this address. It may be possible this email was sent to your Junk folder. Be sure to save your Landlord ID in a secure place. You will need this for future logins.

    Once you’ve successfully logged in, you will land on a page that details all the properties associated with the Landlord ID. Click on View Properties to add and edit your property information. If it is your first time registering, you will not see any information. 

    To access and edit landlord/property manager contact information, click on the Landlord Info link to the top-right of the screen.

  5. Main page

    From the main page, you will need to update two sections.

    Properties subject to registry 

    Follow steps 6 to 9 below.

    Other rental properties

    An owner with property subject to the Marin County Just Cause ordinance must also provide the address of all other rental dwelling units owned in Marin County (Section 5.100.070(f)). This includes properties throughout Marin County regardless of unit count or exemptions. Follow these steps to complete this requirement:

    1. Set your ownership status by selecting the Other Property Ownership Status button at the bottom of the main Property page.
    2. If you own other rental property in Marin County, view or enter the address(es) and number of units by selecting the View/Add Other Properties button.
  6. Property information

    To add a property, click on the Add Property button. You will be prompted to add the following information: 

    • Whether 49% or more of the units on this property are deed-restricted as affordable
    • Property name (a name of your choosing to identify the property)
    • Purchase date
    • Number of parcels on the property
    • Marin County Environmental Health Services (EHS) Permit to Operate number and expiration date
    • Marin County Department of Finance Business License number and expiration date 

    After clicking submit, a property card will populate on the main page.

  7. Parcel information

    After entering property information, you will need to add all parcel information for this property. Click on the Parcel link within the property card, and then click on the Add Parcel button. Here, you will need to add the parcel number and the number of units associated with the parcel.

    If you recently purchased your property, it may be possible that the previous owner already registered with our system. The portal will identify if we already have a record of your parcel number and you will be prompted to follow our Property Transfer instructions.

  8. Unit information

    After entering parcel information, you will need to enter all unit information for the property. You can access the Units page in two places: 

    1. In the property card on the main page
    2. In the parcel card on the parcel page

    In this section, you will need to add the following information: 

    • Unit address
    • Number of bedrooms
    • Whether the unit is exempt from the ordinance
    • Utilities that are included in rent 

    Units are exempt from the ordinance if they: 

    • Are a County-recognized Accessory Dwelling Unit (ADU) or a Junior Accessory Dwelling Unit (JADU)
    • Receive government-subsidized rent (such as Section 8 vouchers)
    • Are occupied by onsite property managers
    • Are in properties where 49% of the units are deed-restricted as affordable. 

    For more information on the exemptions, review Marin County Municipal Code Section 5.100.020(b).

  9. Rental history/annual update

    To complete the registry, you’ll need to ensure that unit rental history is complete for the previous 12 months. You will also need to complete an annual update by January 1 of each year to ensure continued compliance with the ordinance. To access unit rental history, click on the Rental History link for the unit on the Units page.

    You will be asked to select the year you are entering information for in the drop-down menu. After clicking on the Add button, you will be prompted to enter the monthly rent and occupancy status (vacant, occupied, short-term rental and new tenant) for the first month you are entering for the year, which will be duplicated for the rest of that year. 

    You will be able to edit the rental amounts and occupancy status for any months that differ. After completing the unit rental history, the status for the unit will change from a red X (indicating incompleteness) to a green check.
