In 2025, a Denver landlord faced a nightmare scenario after leasing her downtown condo to a single professional. What began as a promising tenancy quickly spiraled out of control when the tenant brought in multiple unauthorized roommates and began renting the unit out for parties on short-term platforms.
From Quiet Tenant to Party Host
For the first month, everything seemed normal. But soon, neighbors began complaining about loud music, overflowing trash, and strangers coming and going at all hours. Police were called several times, and the building’s HOA issued hefty fines for repeated violations.
The landlord, Sarah, discovered her tenant had listed the condo on multiple short-term rental sites without her permission. Unauthorized guests and roommates were living in the unit, violating the lease and city regulations.
Property Damage and Unpaid Bills
When Sarah finally regained access, the condo was in shambles. Hardwood floors were scratched and stained, appliances were broken, and furniture was missing. Utility bills had gone unpaid for months, and the HOA was demanding thousands in fines for rule violations.
- HOA fines: $4,000
- Property repairs: $9,500
- Unpaid utilities: $1,200
- Lost rent during repairs: $3,000
- Total loss: Over $17,000
A Threat of Legal Action
Despite the clear lease violations, the tenant threatened to sue Sarah for “wrongful eviction,” claiming she had a right to sublet the condo. The dispute dragged on for months, costing Sarah additional legal fees and stress.
