How Longmont Handles Property Maintenance: A Practical Guide
Longmont maintains 129 local ordinances across all categories, and 3 of those deal specifically with property maintenance. Here is a breakdown of what the city actually requires, what is prohibited, and where Longmont falls on the strict-to-permissive spectrum compared to other cities.
Snow & Sidewalk Clearing
Longmont gives owners, managers, tenants of an entire premises, and adult occupants of single-family homes 24 hours after snow or ice stops falling to clear the abutting public sidewalk to at least a four-foot width.
Key details: Deadline: 24 hours after snow/ice stops. Clearance width: Sidewalk width or 4 feet. Responsible parties: Owner, manager, tenant, occupant. City can: Clear it and bill offender.
Violation is an offense under the code; the community development director may notify a responsible person and, if uncorrected within 24 hours, have the city clear the walk and add its certified removal costs to the offender's court sentence. Breach also supports civil liability to anyone injured on the uncleared walk.
Property Blight
Longmont expands the International Property Maintenance Code's dangerous-structure criteria with local additions covering structural failure risk, wracked or buckled walls, and buildings that have lost required strength or fire resistance.
Key details: Governing section: LMC § 16.20.100 (IPMC 111.1.5). Damage threshold: 33% supporting / 50% non-supporting. Enforcement: Condemnation, closure, demolition powers. Cost recovery: Lien plus 20% admin fee.
Occupying or maintaining a condemned dangerous structure without written code-official authorization violates § 16.20.120 and can trigger city-ordered demolition with costs, plus a 20 percent fee, liened against the property.
This is not one of those rules that cities tend to ignore. Longmont actively enforces its property blight requirements.
Vacant Lot Maintenance
Once Longmont's city inspector finds evidence of rat infestation on a vacant lot, vacant building or occupied residence, § 9.16.080 requires the owner or occupant to eradicate the rats and stop them from migrating to neighboring property.
Key details: Applies to: Vacant lots, vacant buildings, residences. Trigger: City inspector infestation notice. Deadline: Set by inspector, case by case. Backup enforcement: City abatement plus county lien.
Failure to comply lets the city hire an exterminator under § 9.16.090 and add a 20 percent surcharge as a property lien, collected through the county treasurer like a tax bill.
The Bottom Line
Longmont's property maintenance rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Longmont is broadly strict or permissive.
