Significant changes have been made to Colorado's state laws affecting landlords. New regulations provide tenants with increased rights, such as protection from eviction without reason, a limit on pet rent, and a cap of $300 on refundable pet deposits. Rent can only go up by 5% plus inflation per year. Landlords must return security deposits within a month and give a detailed list of deductions. They are also required to maintain rental units and refrain from discrimination. Mediation is now preferred for resolving disputes before resorting to legal action. Compliance with these laws is crucial for maintaining good tenant relationships.
