A Colorado sublease agreement lets the original tenant (sublessor) rent the Colorado unit, or part of it, to a subtenant (sublessee) while the master lease remains in effect. The original tenant remains liable to the Colorado landlord for rent and lease compliance. Most Colorado leases require the landlord’s written consent to sublet; subletting without consent can be a lease violation and grounds for eviction under C.R.S. § 13-40-104. The sublease should state the rent, the term (not exceeding the master lease), the portion sublet, the security deposit (held consistently with Colorado security deposit law, C.R.S. § 38-12-101 et seq.), and that the sublessee is bound by the master lease. This form does not replace the master lease or override its sublet restrictions.
