Optional Lease Agreement Disclosures and Addendums in Denver

While not mandatory, landlords can add specific disclosures and addendums to their leases. This helps outline the responsibilities of the tenant and can prevent future liability issues.

Medical Marijuana Use Disclosure

Medical marijuana use is legal in Denver—which is why it’s important to disclose if it will be permitted on the property. Colorado law allows landlords to restrict marijuana usage to non-smoking methods only. Clarify if there are designated smoking areas on the premises.

Pet Disclosure

Since Denver is listed as one of the most pet-friendly cities in the U.S., landlords may want to address the building’s pet policies. This disclosure should clarify if pets are allowed on the property, the tenant’s responsibility to cover pet-related damages, and any additional fees or restrictions.

Fire Safety Disclosure

Due to Colorado’s higher wildfire risk, landlords may want to include a fire safety disclosure along with the lease agreement. This should provide information relating to smoke detectors, fire sprinklers, fire safety systems, alarms, and evacuation plans.
