Security Deposit Return Deadline in Colorado

In Colorado, a landlord must return your security deposit within 30 days after move-out (60 days if specified in lease). Missing this deadline often forfeits the landlord's right to keep any portion of the deposit, and many Colorado tenants recover additional statutory damages for bad-faith withholding.

Colorado HOA Law

HOA fines and assessments in Colorado are governed by the Colorado Common Interest Ownership Act (CCIOA) — C.R.S. §38-33.3. This law generally requires written notice, an opportunity to be heard, and documented evidence before a fine becomes enforceable.

Colorado Utility Regulator

Utility billing disputes in Colorado fall under the Colorado Public Utilities Commission (PUC) — puc.colorado.gov. Your utility generally cannot disconnect service while a formal billing complaint is pending with the regulator.
