Traditionally, Colorado law has generally been more friendly to landlords than to aggrieved tenants. Our General Assembly enacted the "implied warranty of habitability." However, to be breached, the conditions must be “materially dangerous or hazardous to the tenant’s life, health, or safety." There are time-consuming notice provisions and rules associated with pursuit of statutory remedies. You should consult an experienced landlord-tenant attorney. Your rights also include the right to move out if you have what amounts to a constructive eviction. Good luck.
