Frequently, landlords and managers have just enough information to be dangerous. One of the most dangerous statements in the business is the "I heard that under Colorado law I do not need a reason to non-renew a tenant". Is this a true statement? Yes, under Colorado landlord tenant law, you do not need a reason to non-renew a tenant. However, under federal and Colorado Fair Housing Laws, you may only non-renew tenants for legitimate non-discriminatory business reasons. While you don't need a reason to non-renew, landlords renew good tenants.
Landlords only non-renew bad tenants for specific reasons. Thus, while under Colorado Landlord-Tenant Law, you do not need to have a reason to win an eviction case or end the relationship with a tenant, you have reasons for non-renewing. If the Colorado Civil Rights Division comes knocking on your door with a discrimination complaint, you will have to provide these reasons for non-renewal. To avoid fair housing liability, your non-renewal reasons must be nondiscriminatory, i.e. based on a legitimate nondiscriminatory business reasons. Accordingly, every non-renewal decision should be thought through in advance to ensure that it is based upon a legitimate non-discriminatory business reason. If you fail to think through the situation and just fall back on the old "I don't need a reason" rationale because you just want a tenant out, you may have a difficult time responding to a discrimination complaint.
