Summary

Littleton's Building Division enforces the 2025 International Property Maintenance Code as locally amended, and Section 602.3 forces any landlord who furnishes heat under a lease to keep habitable rooms, bathrooms and toilet rooms at a minimum 68-degree temperature. The same chapter sets screen, stairway-guard and weed-control minimums, and a property that fails inspection can be placarded as unfit for habitation.

Every owner and operator of any building who rents, leases or lets one or more dwelling units or sleeping units on terms, either expressed or implied, to furnish heat to the occupants thereof shall supply heat to maintain a minimum temperature of 68 ... F (20 ... C) in all habitable rooms, bathrooms and toilet rooms.

Violations & Fines

A landlord who ignores an IPMC order or a Building Division notice is prosecuted under Littleton City Code Section 1-4-1, the General Penalty: a fine of up to $2,650, up to 364 days in jail, and up to a year of probation for adults, with each day the violation continues counted as a separate offense. Minors face the same $2,650 cap without jail time. Placarded units cannot legally be occupied until the code official lifts the notice.

Frequently Asked Questions

What's the minimum temperature my Littleton landlord must maintain?
Under IPMC Section 602.3 as amended by Littleton, any owner who agrees to furnish heat must maintain at least 68 degrees Fahrenheit in every habitable room, bathroom and toilet room. The floor drops to 65 degrees only in months when the average outdoor temperature is above 30 degrees, or is suspended when it's colder than the winter design temperature and the furnace is already running at full capacity.
Can my landlord be fined for not fixing a broken screen door or unsafe stairs?
Yes. Section 304.14 requires self-closing insect screens of at least 16 mesh per inch on required openings, and Section 307.1 requires 34 to 38 inch handrails and 36 inch guards on stairs and elevated walking surfaces. A code official who finds a violation can issue a notice, and continued noncompliance is prosecuted under the General Penalty, Section 1-4-1.
What does it mean if the city placards my apartment building?
Under Section 111.7, the Building Division's code official posts a placard when a structure is unsafe or unfit for habitation. It must stay in a conspicuous spot, and occupying the unit, operating condemned equipment, or removing the placard yourself is itself a violation carrying the same fine and jail exposure as the underlying maintenance offense.
