As a tenant, you have certain obligations to the premises in terms of upkeep and maintenance under Colorado Landlord Tenant Statutes. These obligations may not appear in your lease agreement, but you are no less responsible for not only knowing them, but upholding your obligations.
Every lease agreement carries with it an implied warranty of habitability. That is, the landlord warrants to the tenant that the premises leased to the tenant for the purpose of habitation is in fact suitable for human habitation. This does not need to be written in your lease in order to be in effect; the implied warranty of habitability is implied in every lease agreement.
Security deposit disputes are a common occurrence between renters and landlords in Denver and the surrounding state of Colorado. Having an attorney like Nathaniel Gilbert can be a big advantage in negotiating and navigating the rules, requirements and deadlines associated with the process of disputing a security deposit.
