Colorado landlords in Littleton must: return security deposits within 30 days of move-out (or 60 days if the lease allows), provide at least 21 days' written notice before raising rent or ending a month-to-month tenancy, maintain a habitable property under the Colorado Warranty of Habitability (C.R.S. § 38-12-503), and follow the court-supervised eviction process under C.R.S. § 13-40-101.

Littleton sits at the intersection of Jefferson and Arapahoe counties, which means landlords here need to stay current with both state-level Colorado law and any applicable county court procedures, particularly when filing an eviction in the Jefferson County or Arapahoe County combined courts. Colorado has also passed a wave of tenant-protection legislation since 2019, including the Rental Application Fairness Act, the Eviction Representation pilot, and expanded habitability standards, making compliance more complex than it was just a few years ago. Whether you own a duplex near the historic Old Town Littleton district or a single-family rental backing up to Clement Park, knowing your obligations protects both your investment and your residents.

What are the security deposit rules a Littleton landlord must follow?

Under C.R.S. § 38-12-102, you must return a tenant's security deposit, along with an itemized written statement of any deductions, within 30 days after the tenancy ends and the tenant delivers possession. If the lease specifically authorizes a longer period, that period can extend to 60 days, but it cannot exceed 60 days under any circumstances.

Deductions are limited to unpaid rent, damage beyond normal wear and tear, and other costs the lease expressly permits. "Normal wear and tear" is not defined by statute, but Colorado courts have consistently held that minor scuffs on paint, small nail holes, and carpet wear from ordinary foot traffic do not qualify as deductible damage. Document the property's condition with dated photos and a written move-in checklist, both of which will be critical if a tenant disputes your deductions.

If you wrongfully withhold a deposit, C.R.S. § 38-12-103 gives the tenant the right to sue for the wrongfully withheld amount plus up to three times that amount as a penalty, along with attorney fees. On a $2,500 deposit, that exposure is up to $10,000. Missing the 30-day deadline, even by one day, can cost you that entire penalty, so calendar the deadline the moment a tenant hands back the keys.

How much notice does a Colorado landlord have to give before raising rent or ending a tenancy in Littleton?

Under the Rental Fairness Act (SB 21-173, codified at C.R.S. § 38-12-701), landlords must give at least 21 days' written notice to terminate a month-to-month tenancy or to raise rent, a significant change from the older common-law standard of 10 days for tenancies of one month or less.

For tenancies longer than one month but less than six months, the required notice is 28 days. For tenancies of six months to one year, the required notice is 91 days. For tenancies of one year or longer, the required notice is 182 days (six months). These notice periods apply specifically to rent increases and non-renewal terminations; they do not apply when you are terminating for cause, such as nonpayment of rent or a lease violation.

Rent increases during a fixed-term lease are generally prohibited unless the lease explicitly authorizes them. Littleton landlords with long-term tenants near sought-after spots like Arapahoe Community College or along South Santa Fe Drive should be especially careful to document lease renewal dates and provide proper advance notice well before the end of any lease term.

What does the Colorado Warranty of Habitability require landlords to provide?

Under C.R.S. § 38-12-503, every residential rental in Colorado, including those in Littleton, must be habitable at the start of the tenancy and maintained in that condition throughout. The statute defines habitability to include: functioning plumbing and hot water, adequate heat (capable of maintaining 68°F), a weathertight structure, working electrical systems, no infestation of rodents or insects, and no presence of mold caused by landlord negligence.

As of 2021, the law was strengthened to give tenants a clearer remedy path. If a landlord receives written notice of a habitability problem and fails to begin remediation within a reasonable time, generally interpreted as 24 hours for emergency conditions like no heat in a Colorado winter and up to 72 hours for other urgent issues, the tenant may be entitled to withhold rent, terminate the lease, or sue for damages.

Littleton's winters are real: temperatures at Chatfield State Park a few miles south can drop well below zero, and a furnace failure is never a minor issue here. Build a relationship with a licensed HVAC contractor who can respond quickly, and make sure your property has adequate attic insulation and weather-stripping on exterior doors, not just for habitability compliance, but because prospective tenants compare energy costs when choosing a rental.

What is the legal eviction process a landlord in Littleton must follow?

Colorado's eviction process, formally called a Forcible Entry and Detainer (FED) action under C.R.S. § 13-40-101, requires a landlord to serve a written notice, wait for it to expire without cure, file in court, obtain a judgment, and then have the sheriff execute a writ of restitution. Self-help evictions, such as changing locks, removing a tenant's belongings, or shutting off utilities, are illegal in Colorado and expose the landlord to significant civil liability.

The type of notice required depends on the reason for eviction. For nonpayment of rent, the landlord must serve a Demand for Compliance or Possession (commonly called a "10-day notice," though SB 21-173 extended this to 10 days with the right to cure by paying in full). For a lease violation other than nonpayment, the notice must give the tenant 10 days to cure or vacate. For an unconditional termination of a month-to-month tenancy with no fault alleged, the 21/28/91/182-day notice requirements described above apply.

Littleton cases filed in Jefferson County are heard at the Jefferson County Combined Court at 100 Jefferson County Pkwy in Golden, while properties on the Arapahoe County side of Littleton, including parts of the Highlands Ranch adjacent areas, file at the Arapahoe County Justice Center. Filing fees, scheduling timelines, and local court practices differ slightly between the two courthouses, which is one reason many Littleton landlords choose professional management to handle this process on their behalf.

What are a landlord's fair housing and rental application obligations in Littleton?

Colorado landlords must comply with the federal Fair Housing Act, the Colorado Fair Housing Act (C.R.S. § 24-34-502), and the Rental Application Fairness Act (RAFA, C.R.S. § 38-12-902). Together, these laws prohibit discrimination based on race, color, national origin, religion, sex, familial status, disability, and, under Colorado law, sexual orientation, gender identity, marital status, and source of income in many jurisdictions.

Under RAFA, landlords must: disclose all rental criteria in writing before accepting an application fee, cap the application fee at the actual cost of screening (not to exceed $30.32 as adjusted for inflation, verify the current cap before charging), and provide a written notice of denial that states the specific reason. If income from a housing voucher or other assistance program qualifies as a protected source of income under local ordinance, refusing to accept it may constitute illegal discrimination.

Arapahoe County and the City of Littleton do not currently have a blanket source-of-income protection ordinance at the municipal level, but state law continues to evolve rapidly on this issue. Landlords should review their screening criteria at least annually and ensure application templates are current. Inconsistent screening, such as approving one applicant with a prior eviction while rejecting another with the same record, is one of the most common triggers for fair housing complaints.

What disclosure requirements apply to Littleton rental properties?

Colorado law requires landlords to disclose several specific facts to tenants before or at lease signing. Under C.R.S. § 38-12-801, landlords must disclose in writing: the name and address of the property owner and any authorized manager, the existence of any pending foreclosure on the property, and the existence of any known mold conditions. Federal law also requires a lead-based paint disclosure for properties built before 1978.

Older homes in Littleton's historic core, particularly those built along West Littleton Boulevard and the neighborhoods around South Curtice Street that date to the 1950s and 1960s, frequently trigger the lead-paint disclosure requirement. Landlords must provide the EPA's "Protect Your Family from Lead in Your Home" pamphlet and disclose any known lead hazards in writing. Failure to provide the federally required lead disclosure can result in civil penalties up to $11,000 per violation and criminal penalties in cases of willful noncompliance.

Colorado does not currently have a mandatory statewide radon disclosure law for residential rentals, but the Colorado Department of Public Health and Environment reports that Arapahoe and Jefferson counties both have elevated radon potential. Testing a property before leasing and disclosing results to tenants is a best practice that reduces liability and builds trust with residents who are increasingly aware of indoor air quality issues.
