The Landlord-Tenant Handbook
is current as of Jan. 1, 2019 but there is no assurance that the laws have not changed or been amended. The handbook summarizes existing State of Colorado and City of Boulder residential landlord-tenant law and addresses many of the questions that arise both before and after a lease is signed. The information in The Landlord-Tenant Handbook does not constitute legal advice.This information is intended to serve only as a general guide and is not intended to be used as a substitute for seeking advice from a qualified attorney. A hard copy of the handbook is available at our office at 2160 Spruce Street in Boulder. To receive a hard copy by mail, leave a message at 303-441-4364 with your name and mailing address.

Note: Due to a Colorado Supreme Court ruling that found last month’s rent to be pre-paid rent, interest is not due on last month’s rent held by the landlord. All other refundable deposits including pet deposits should be included in the computation.
Example computations:
A. $1,000 deposit on a two-year lease starting on Aug. 1, 2002, and ending July 31, 2004. Landlord received the deposit at lease signing on May 1, 2002, and is mailing it back on Sept. 27, 2004. $1,000 x .055 = $55 (this equals one year’s interest) divided by 12 = $4.58 (one month’s interest) x 29 (number of month’s held by landlord) =$132.82.
B. $800 deposit on a 13.5 month lease which rolled over into a month-to-month tenancy after the initial year written lease. Tenant moved in and paid the deposit on May 15, 2003 and moved out with proper notice on Sept. 30, 2004. Landlord is returning the deposit on Oct. 31, 2004. $800 x .055 = $44 divided by 12 = $3.67 (one month’s interest rate until May 15, 2004) x 12=$44.04 (or $44 even) plus $800 x .0108=$8.64 divided by 12 =$ .72 x 5.5 months =$3.96. Total interest due is $3.96 + $44 = $47.96.
