  • Security Deposit Calculator Glitch Resolved+

    I wish to apologize to all our users regarding our recent down time for the security deposit calculator. We upgraded another section of our website and it appears to have caused the link in which we project the calculator to break.. This only impacted the calculators interactivity with the website and not the workings of the calculator it self.

    A special shout out for the users who quickly called attention to the glitch as it allowed us to jump on it right away.

    Thank you

  • Why do the calculations between August 4, 2002 and June 14, 2003 follow a different pattern?+

    In this period, the San Francisco Administrative Code changed the method for calculating interest on security deposits.

    As Jeffery P. Woo reported on the San Francisco Apartment Association Website, "The Rent Board takes the position that for any interest payment paid after March 1, but prior to June 15, all three interest periods must now be accounted for." ReLISTO's SF Security Deposit Interest and Rent Board Fee Calculator calculates all three interest periods.

  • Tenant vacating: If selected, why does this change the value?+

    The exact language from the San Francisco Rent Board website is in quotes below. In short, if the tenant is terminating their tenancy, then interest is due through the last day. By checking the box, this value will be calculated.

    From the Rent Board: "Where a tenant vacates after one year of occupancy but before the next annual due date, the interest payment for the partial year period must be pro-rated and calculated using the interest rate in effect on the date the tenant vacates."

  • How does the calculator establish the daily rate of interest?+

    The daily rate of interest is based on the number of days in the current year.

  • When is security deposit interest owed?+

    Per the SF Rent Board Website: "Interest must be paid every year on the tenant's "annual due date." For tenancies beginning after September 1, 1983, the annual due date is the same day and month the landlord received the deposit from the tenant. (If the tenant moved in and paid a deposit before September 1, 1983, interest was due on September 1, 1984 and every September 1st thereafter.) "

    The calculator follows the rules laid out by the SF Rent Board very closely. Interest rate is based on the rate in effect on the "Due Date"

  • Does the rent board fee always apply?+

    Majority of  rental properties  in San Francisco are   assessed a rent board fee. If  assessed ,  the landlord may pass 1/2 of this fee along to their tenants. If they were not assessed the fee then they cannot pass along this fee. Refer to Section 37A.1 of the Administrative Code for a complete list of exemptions.
