Overview
At 14.5 inches of yearly rain and an average of 51.2 F, Aurora experiences infrequent rain but high sensitivity to leaks when storms hit.
Aurora shares Colorado cold winters and low humidity, so moisture risk rises with snowmelt and winter leaks.
Aurora Neighborhood Services supports code compliance and neighborhood standards.
Aurora code enforcement administers the municipal code and property maintenance standards and responds to code complaints.

Warning Signs of Mold in Aurora
Watch for these signs that moisture is lingering in Aurora homes and rentals:
- Window condensation that persists during warm weather in Aurora (average temperature 51.2 F) often signals excess indoor humidity.
- Condensation that returns on windows each morning.
- Peeling paint near baseboards or window trim.
- Musty odors in basements or closets.
- Dark spotting near ceiling vents.
- Soft drywall around bathrooms.

Mold Risk Factors in Aurora
These are the most common moisture drivers for homes and rentals in Aurora:
- Low rainfall of 14.5 inches annually means Aurora mold problems typically trace back to plumbing failures and HVAC moisture, not rain.
- Snow accumulation and melt can wet roof edges and attic insulation.
- Freeze thaw cycles can open small gaps around windows and doors.
- Condensation can build on windows during cold nights.
- Basement walls can stay damp after spring melt.
- Slow plumbing leaks can stay hidden in cabinets.

Aurora Moisture Playbook
Use this short playbook to stay ahead of common moisture problems in Aurora.
After a Leak
Stop the source, remove wet materials, and dry the area within 24 to 48 hours.
Monthly Maintenance
Check under sinks, clear condensate lines, and monitor indoor humidity.
Seasonal Tune Up
With only 14.5 inches of yearly precipitation, any storm is significant. Prep window seals and drainage before wet weather.

Mold Prevention in Aurora
Use these priorities to keep indoor humidity low and avoid recurring growth:
- Despite only 14.5 inches of annual rainfall, seal window and door gaps before storms to prevent water intrusion.
- Maintain indoor humidity between 30 and 50 percent.
- Dry wet materials within 24 to 48 hours.
- Vent bathrooms and kitchens outdoors.
- Inspect roof flashing and gutters before winter.
- Check basements after snowmelt.
- Service HVAC humidifiers and condensate drains annually.

State Laws and Rights
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 96 hours for other conditions after receiving proper notice.
