TL;DR
Denver requires a rental license for any residential unit rented to tenants, including single-family homes, ADUs, and rooms. Owner-occupied duplexes are the main exemption. Licensing runs through Denver's Excise and Licenses department, requires a passed inspection (self-certified or third-party depending on property type), and violations can bring daily fines. Confirm current fees and deadlines with Denver's rental licensing office before you file.
Does Denver require a landlord license?
Yes. Denver's rental licensing law, passed in 2021 and phased in through 2023, requires anyone renting out residential property in the city to hold a valid rental license before advertising or leasing a unit. This covers single-family homes, condos, apartments, accessory dwelling units, and even individual rented rooms in most cases. The ordinance lives in Denver Municipal Code Chapter 12, Article XVI [1]. The rule applies whether you own one rental house or ten. Denver did not carve out a small-landlord exemption the way some cities do. If you're a landlord with a single rental unit inherited from a parent, or a small operator with a handful of properties around the city, you're in the same licensing system as a large property management company. The main exemptions are owner-occupied units where the owner lives in one part of a duplex and rents the other, certain licensed group living arrangements, and a few other narrow categories spelled out in the ordinance [1]. If you're new to landlording generally and want the basics on becoming a landlord before you get into Denver's specific paperwork, that's covered further down in this piece. Denver rolled the requirement out in phases by property size, with larger buildings required to comply first (2022) and smaller properties, including single-unit rentals, phasing in by January 1, 2023 [2]. If you missed that deadline and haven't licensed your unit yet, you're already out of compliance and should treat this as urgent, not routine paperwork.
Who needs a rental license in Denver?
Any owner of residential rental property in Denver needs a license, per unit, before that unit can legally be leased. That includes: Single-family homes rented to tenants. Duplexes, triplexes, and larger multifamily buildings. Condos and townhomes rented out by their owners. Accessory dwelling units (ADUs), sometimes called mother-in-law units or carriage houses, when rented separately. Individual rooms rented in a shared house, in many cases. The license attaches to the unit, not to the landlord as a person. If you own three rental houses in Denver, you need three separate licenses, one per address, each renewed and inspected on its own schedule. Owner-occupied exemption: if you live in one unit of a two-unit property and rent the other unit, Denver's ordinance generally exempts that arrangement from licensing, though you should confirm the exact wording still applies to your situation with Denver's Excise and Licenses office, since municipal exemptions get amended [1]. This exemption typically does not extend to three-plus unit buildings even if the owner lives on site. Short-term rentals (stays under 30 days) fall under Denver's separate short-term rental licensing program, not the long-term rental license described here [3]. If you rent a property short-term part of the year and long-term the rest, you may need to sort out which license applies, or both.
How do you apply for a Denver rental license?
You apply online through Denver's Excise and Licenses department, and the process generally runs through these steps: register the property, pass an inspection (self-certification or third-party depending on unit count), pay the fee, and receive your license number. Renewal happens on a set cycle, typically annual, though you should confirm the current renewal term with the city. Here's the general shape of it: 1. Create or log into your Denver rental license account through the city's licensing portal. 2. Enter property details: address, unit count, property type. 3. Complete the required inspection. Smaller properties (four units or fewer, in most cases) can often use a self-certification checklist; larger properties typically require inspection by a licensed, city-approved third-party inspector [4]. 4. Submit proof of inspection and pay the license fee. 5. Receive your rental license, which must be posted or made available to tenants as required. Denver's rental license fees vary by number of units and have changed since the program launched, so confirm the current fee schedule with Denver's Excise and Licenses office before budgeting. Early published guidance put per-unit and base fees in the range of roughly $50 to $100 depending on unit count, but treat any specific number you see online, including here, as needing a final check against the city's current fee page [5]. If you're assembling the inspection checklist, lead paint disclosures, smoke and CO detector documentation, and other paperwork the city wants to see, a rental packet builder can save you the time of hunting down every requirement separately; it's a $79 one-time tool built around exactly this kind of city licensing packet, not a subscription.
What does the Denver rental inspection check?
Denver's rental inspection focuses on basic health and safety systems: smoke alarms, carbon monoxide detectors, electrical safety, plumbing, heating, structural soundness, and habitability items like working locks and adequate egress. The city publishes a checklist that self-certifying landlords use to walk their own property before submitting. For units eligible for self-certification, the checklist typically covers: smoke detectors in every bedroom and on every level, a carbon monoxide detector if the unit has fuel-burning appliances or an attached garage, functioning heat, hot and cold running water, no exposed wiring, secure locks on exterior doors, and no obvious pest infestation or mold [4]. Landlords sign and submit the checklist attesting the property meets these standards; false certification can carry consequences beyond a normal violation, since it's a signed attestation to the city. Larger properties or those that don't qualify for self-certification need a walk-through by a Denver-approved third-party inspector, who checks the same categories in person and files the report with the city. This is a good spot to answer a related question landlords in other states ask a lot: who's responsible for the rental property walk-through inspection in California? California doesn't have a statewide rental licensing inspection like Denver's; inspection responsibility there is mostly local (city or county code enforcement, often triggered by complaint) plus move-in/move-out walk-through obligations between landlord and tenant under California Civil Code Section 1950.5, which governs security deposit itemization and the option for an initial move-out inspection [6]. California's rules are a different system entirely from Denver's proactive licensing inspection, worth knowing if you own property in both places.
What happens if you rent without a license in Denver?
Operating an unlicensed rental in Denver can bring code enforcement action, fines, and in some cases an order to stop renting the unit until you're compliant. Denver's municipal code allows for daily penalties for continuing violations, and enforcement has picked up since the phase-in deadlines passed [1]. Practically, this plays out a few ways. A tenant complaint, a neighbor complaint, or a routine city sweep can trigger a check on whether a rental is licensed. If it's not, the city typically issues a notice first, giving you a window to get licensed and inspected. Ignore that notice and you're looking at escalating fines, and in a worst case, the city can pursue an order that stops you from leasing the unit at all until you're compliant. There's also a practical exposure landlords sometimes miss: an unlicensed rental can complicate your position in a dispute with a tenant, since you're the one out of compliance with a mandatory city ordinance. That's a separate issue from criminal or civil eviction defenses, but it's not a good position to be negotiating from. If you got a notice and are scrambling, the fastest path is usually: confirm your license status on Denver's portal, schedule or complete self-certification/inspection immediately, and pay any fee shown. Don't wait for a hearing date to start that process.
How much does a Denver rental license cost?
| License application/renewal fee | Landlord | Set by Denver Excise and Licenses, confirm current amount | |
|---|---|---|---|
| Third-party inspection (5+ units, in most cases) | Landlord | Inspector fees are separate from the city license fee | |
| Repairs to pass inspection | Landlord | Smoke/CO detectors, lock repairs, minor electrical fixes are common | |
| Late fees for expired license | Landlord | Applies if renewal lapses before re-inspection | A reasonable rule of thumb: budget for the license fee itself, plus a buffer of a couple hundred dollars for small repairs (a new smoke detector here, a door lock there) that often surface during a first inspection. Most single-family rentals in reasonable condition pass without major work, but older housing stock in Denver neighborhoods like Cole, Globeville, or West Colfax sometimes needs electrical or window repairs to clear the checklist. |
Denver's rental license fees are structured per property, generally scaled to the number of units, with additional charges tied to third-party inspections for larger buildings. Because the city has adjusted this fee schedule since the ordinance passed in 2021, don't rely on any fixed dollar figure you find in an older blog post, including estimates elsewhere in this piece; confirm the current schedule directly with Denver's Excise and Licenses rental license fee page before budgeting [5]. What you should budget for beyond the license fee itself: | Cost item | Who typically pays | Notes |
What is landlording, and what is a landlord?
A landlord is a person or entity that owns residential or commercial property and rents it to someone else (a tenant) in exchange for regular payment, usually monthly rent, under a lease or rental agreement. Landlording is the ongoing work of managing that relationship: collecting rent, maintaining the property, handling repairs, following local and state law, and dealing with tenant turnover. It sounds simple until you're doing it. Landlording in a city like Denver means juggling the rental license itself, habitability standards under Colorado law, security deposit rules, notice requirements for entry and non-renewal, and now, on top of all that, the annual licensing and inspection cycle. None of these obligations are optional extras; they're the baseline of operating legally. Colorado law defines the landlord-tenant relationship and baseline obligations in the Colorado Revised Statutes, Title 38, Article 12, which covers security deposits, the warranty of habitability, and related landlord duties [7]. Denver's municipal rental licensing law sits on top of that state framework as an additional city-level requirement, not a replacement for it.
How do you become a landlord, and how do you actually be one, day to day?
Becoming a landlord in Denver (or anywhere) starts before you ever list a unit: you need to know your state's landlord-tenant law, your city's licensing rules, and a realistic budget for repairs, insurance, and vacancy. Buying or converting a property into a rental is the easy part; running it well over years is the harder skill. A reasonable starting checklist: 1. Confirm zoning allows rental use at your address (some Denver neighborhoods have overlay restrictions, particularly for short-term rentals or room rentals). 2. Get your Denver rental license before you advertise the unit, not after you find a tenant. 3. Screen tenants consistently and legally; Colorado and federal fair housing law both apply. 4. Use a written lease. Colorado doesn't strictly require a written lease for it to be enforceable, but a written lease is how you protect yourself if there's a dispute later. 5. Carry landlord insurance (different from a standard homeowner's policy) and decide your policy on requiring renters insurance. 6. Budget for maintenance and repairs before your first tenant moves in, not after something breaks. 7. Track your renewal and inspection dates. Denver licenses aren't a one-time thing; missing a renewal window puts you right back in violation territory. Being a landlord day to day is mostly maintenance, communication, and paperwork discipline. The legal risk isn't usually in the big dramatic disputes; it's in the small stuff landlords let slide, like an expired license, a missed notice period, or a security deposit return that's a few days late.
How much notice does a landlord have to give?
Notice requirements depend on what the landlord is doing: entering the unit, ending a tenancy, or raising rent, and Colorado sets some of these at the state level while Denver may add local wrinkles. For entry, Colorado doesn't set one single statewide notice period in statute the way some states do, so many landlords follow a 24-hour notice practice as a reasonable standard, and your lease should specify the number. For ending a month-to-month tenancy, Colorado Revised Statutes Section 13-40-107 sets notice periods scaled to how long the tenant has lived there: for tenancies of one year or longer, the statute generally requires 91 days' notice; for tenancies between six months and one year, 28 days; for tenancies one to six months, 21 days; and for week-to-week tenancies, 3 days [8]. These are the state law defaults for terminating without cause; local Denver ordinances or eviction protection rules can add requirements on top, so check current Denver-specific tenant protection rules before sending any termination notice. Rent increase notice for month-to-month tenants generally follows similar timelines under the same statute, since a rent increase legally functions as a change to a periodic tenancy that requires notice to terminate the old terms. Don't guess on this one: use the current statute text or a local attorney to confirm the exact number of days for your specific tenancy length before you send anything.
What rights do tenants have without a lease?
A tenant without a written lease still has legal rights, because Colorado law (like most states) recognizes oral and month-to-month tenancies as legally enforceable. Lack of a written lease doesn't mean lack of protection; it usually just means the tenancy defaults to month-to-month terms under state law. A tenant without a written lease in Colorado still gets: the state's implied warranty of habitability, protection from illegal lockouts or utility shutoffs, the same statutory notice periods for termination described above (tied to how long they've lived there, not to whether they signed paperwork), and the right to the return of any security deposit under the timelines in Colorado Revised Statutes Section 38-12-103, which generally requires deposit return within one month of move-out unless the lease specifies otherwise, up to 60 days [7]. What a tenant without a lease does not automatically get is a fixed term of occupancy. Without a signed lease specifying, say, a 12-month term, the tenancy is presumed month-to-month, and either side can end it with proper statutory notice. That cuts both ways: a landlord can't be locked into an indefinite unwritten commitment, but a tenant also isn't protected from a notice to vacate the way they would be under a signed fixed-term lease. If you're managing tenants without paperwork in place, it's worth reading up on tenants rights and tenant rights generally, since the absence of a written lease is one of the more common sources of landlord-tenant disputes.
Why do landlords require renters insurance?
Landlords require renters insurance mainly to shift liability for the tenant's personal property loss and personal liability claims away from the landlord's own policy. A standard landlord or property insurance policy covers the building itself, not the tenant's furniture, electronics, or clothing, and it typically doesn't cover a lawsuit if the tenant's guest gets hurt in the tenant's unit due to the tenant's own negligence. Requiring renters insurance (often in the $10 to $30 a month range depending on coverage and location) also reduces the odds that a fire, water damage, or theft claim inside a tenant's unit turns into a landlord dispute over who owed what. If a tenant's candle starts a fire and their laptop and clothes are destroyed, the landlord's policy generally isn't paying to replace those items; the tenant's own renters policy would, if they have one. Colorado law doesn't require renters insurance statewide, and Denver's rental license ordinance doesn't mandate it either, but it's common for individual landlords to require it as a lease condition. If you do require it, spell out the minimum liability coverage amount in the lease and ask for proof of an active policy at move-in and renewal; the requirement is only useful if you're actually verifying compliance, more than writing it into the lease and forgetting about it.
What can a landlord look at during an inspection?
During a Denver rental license inspection, whether self-certified or done by a third-party inspector, the inspector is checking safety systems and habitability items, not the tenant's personal belongings or private areas beyond what's needed to verify those systems. Expect a check of smoke detectors, carbon monoxide detectors, electrical panels and outlets, plumbing fixtures, heating systems, window and door locks, and general structural condition [4]. During a routine landlord property inspection outside the licensing context (a standard lease-term walkthrough, for example), what a landlord can look at is generally limited to verifying the property's condition and confirming no lease violations, not searching through the tenant's belongings. Colorado's habitability and entry rules, along with the general legal principle that tenants have a right to quiet enjoyment of the property, mean a landlord's inspection should be about the property (walls, fixtures, appliances, safety equipment) and not a pretext for going through drawers, closets, or personal items. A related question that comes up from landlords with properties in multiple states: what a landlord cannot do in Ohio. Ohio's landlord-tenant law, Ohio Revised Code Chapter 5321, generally requires landlords to give reasonable notice before entering (Ohio courts and the statute point to 24 hours as the common standard for non-emergency entry) and prohibits a landlord from entering at unreasonable times, entering repeatedly to harass a tenant, or using self-help eviction methods like shutting off utilities or changing locks to force a tenant out [9]. That last part, the ban on lockouts and utility shutoffs as an eviction shortcut, is consistent with most states, including Colorado, and it's one of the more common ways landlords accidentally cross a legal line when they're frustrated with a nonpaying tenant.
What should you do right now if you got a Denver rental compliance notice?
If you've received a notice from Denver about an unlicensed rental or a missed inspection, the first move is to check your property's status directly on Denver's rental licensing portal rather than guessing based on the notice's wording. Notices can be triggered by a tenant complaint, a routine sweep, or an expired license, and the fastest path back into compliance depends on which one applies to you. Here's a reasonable sequence: 1. Log into Denver's Excise and Licenses rental license portal and confirm exactly what's missing (application, inspection, fee, renewal). 2. If you've never applied, start the application immediately; don't wait for a hearing date. 3. If you need a self-certification inspection, walk the checklist yourself first (smoke detectors, CO detectors, locks, no exposed wiring) so you're not caught by a fixable item you missed. 4. If your property needs a third-party inspector (larger buildings), schedule that inspection as soon as possible; these inspectors often have a backlog, so don't wait until the week before a deadline. 5. Pay any fee shown, and keep a copy of your confirmation for your own records in case of a dispute later. This is also where a lot of landlords realize they don't have their supporting paperwork organized, lead paint disclosures, prior inspection records, proof of smoke/CO detector installation, in one place. A rental packet builder built specifically around city licensing requirements ($79 one-time) can shortcut the process of assembling that packet correctly the first time, which matters more in Denver than in cities with lighter enforcement, since Denver's fines escalate the longer a unit stays unlicensed.
Frequently asked questions
How much does a Denver rental license cost?
Denver's rental license fee varies by unit count and has changed since the ordinance passed in 2021. Rather than rely on a fixed number, confirm the current fee schedule directly with Denver's Excise and Licenses rental license office before budgeting, since older published estimates may no longer be accurate.
Do I need a rental license for a single-family home in Denver?
Yes. Denver's rental licensing ordinance applies to single-family homes rented to tenants, more than multifamily buildings. The requirement phased in for smaller properties by January 1, 2023, so a single rental house is treated the same as a larger property under the ordinance.
What happens if I rent without a license in Denver?
You risk code enforcement action and fines, which can escalate daily under Denver Municipal Code Chapter 12, Article XVI. The city typically issues a notice first, giving you a window to get licensed and inspected before penalties increase or the city orders you to stop leasing the unit.
How do you become a landlord?
Becoming a landlord means acquiring or converting a property for rental use, learning your state and city's landlord-tenant law, budgeting for repairs and vacancy, getting proper insurance, and, in cities like Denver, obtaining a rental license before you advertise or lease the unit to anyone.
Who is responsible for the rental property walk-through inspection in California?
California doesn't run a statewide licensing inspection like Denver's. Inspection responsibility is mostly local code enforcement, plus a move-out walk-through right under California Civil Code Section 1950.5, which lets tenants request an initial inspection before the final deposit deduction is made.
What is landlording?
Landlording is the ongoing work of owning and managing rental property: collecting rent, maintaining the unit, following state and local landlord-tenant law, and handling tenant turnover. It's distinct from simply owning real estate, since it involves an active legal relationship with a tenant.
What is a landlord?
A landlord is a person or entity that owns property and rents it to a tenant under a lease or rental agreement in exchange for regular payment. Landlords hold legal responsibilities under state law and, in cities like Denver, additional municipal licensing obligations.
What rights do tenants have without a lease?
Tenants without a written lease in Colorado still get habitability protections, statutory notice periods before termination (based on tenancy length), and security deposit return rights under Colorado Revised Statutes Section 38-12-103. Lack of a written lease generally defaults the tenancy to month-to-month, not to no rights at all.
Why do landlords require renters insurance?
Landlords require renters insurance to cover the tenant's personal property and personal liability, since a landlord's own insurance policy typically doesn't cover a tenant's belongings or liability claims from incidents the tenant caused inside their unit. It also reduces disputes after fires, floods, or theft.
How much notice does a landlord have to give?
In Colorado, notice to end a month-to-month tenancy scales with how long the tenant has lived there: generally 91 days for tenancies over a year, 28 days for six months to a year, 21 days for one to six months, and 3 days for week-to-week, under Colorado Revised Statutes Section 13-40-107.
What can a landlord look at during an inspection?
A Denver rental license inspection checks safety systems: smoke and carbon monoxide detectors, electrical wiring, plumbing, heating, and secure locks. Routine lease-term inspections should focus on the property's condition and lease compliance, not a tenant's personal belongings beyond what's needed to verify those systems.
What can a landlord not do in Ohio?
Under Ohio Revised Code Chapter 5321, an Ohio landlord generally cannot enter without reasonable notice (commonly treated as 24 hours), enter repeatedly to harass a tenant, or use self-help eviction methods like shutting off utilities or changing locks to force a tenant out without going through the courts.
Does Denver exempt owner-occupied duplexes from rental licensing?
Generally yes. Denver's ordinance typically exempts a unit where the owner lives in one part of a duplex and rents the other. This exemption usually doesn't extend to three-plus unit buildings even with an owner living on site, so confirm your specific situation with Denver's Excise and Licenses office.
