Colorado mold law snapshot
Colorado has mold-specific rules in addition to general habitability standards.
Under Colorado's Warranty of Habitability (C.R.S. 38-12-503), every landlord is deemed to warrant that the residential premises is fit for human habitation at the start of tenancy and throughout the entire rental period. The warranty cannot be waived by any lease provision. Mold associated with dampness is specifically listed as a condition that can breach this warranty. A landlord breaches the warranty if they fail to commence remedial action within 24 hours for conditions that materially interfere with the tenant's life, health, or safety, or within 72 hours for other conditions after receiving proper notice.

Repair Notices and Rent Decisions
Start with these Colorado rules, then check the local regulations section and your property's coverage. A statutory notice period is not always a deadline for finishing every repair. Keep proof of notice and get local legal advice before changing rent payments or ending a lease.
How long does a Aurora landlord have to fix mold?
Colorado's SB24-094 distinguishes starting remedial action from finishing repairs. Action must begin within 24 hours for conditions materially interfering with life, health, or safety, or within 72 hours for other covered conditions, subject to statutory exceptions. For covered mold or dampness, applicable containment, stopping active water sources, and HEPA filtration tasks must occur within 72 hours of notice. Record each milestone; these rules do not mean all remediation must be completed in 72 hours.

Can Aurora tenants withhold rent for mold?
Tenants may deduct the cost of mold remediation from rent if the landlord fails to remedy the condition. The tenant must provide at least 10 days advance written notice of intent to hire a licensed professional (or 48 hours if the condition materially affects health or safety). The notice must include specific information including the condition, date of original notice to landlord, and a good-faith cost estimate from an unrelated, licensed professional. If the landlord does not obtain alternative estimates within 4 business days, the tenant may proceed with deductions. Tenants cannot hire relatives to perform the work.

Does mold in Aurora require relocation?
