Boulder short term rental license: rules, fees, and steps

Last updated 2026-07-26

Does Boulder require a license for short term rentals?

Yes. Boulder's municipal code requires anyone renting a dwelling unit (or part of one) for fewer than 30 consecutive days to hold a short term rental license before advertising or accepting bookings, under Boulder Revised Code Chapter 10-3.5 ^[1]. This applies whether you rent out a spare bedroom a few weekends a year or run a whole-house rental full time through a platform like Airbnb or Vrbo. Boulder created its STR licensing ordinance to address neighborhood impact concerns (noise, parking, safety) and to make sure short term rentals get inspected like other rental housing in the city. The licensing requirement sits alongside Boulder's broader rental housing rules, which is why owner-occupied units and non-owner-occupied units are treated differently under the code. If you're renting through a platform and don't yet have a city license number, you're operating outside the ordinance. That's exactly the kind of gap code enforcement complaints tend to expose. Confirm your specific address's zoning eligibility with the City of Boulder's short term rental program before you list anything, because not every zone district allows every license type ^[1].

What license types exist for Boulder short term rentals?

Boulder's ordinance sorts short term rental licenses primarily by whether the owner lives on site. The two broad categories are owner-occupied short term rentals (where the owner or a long-term tenant lives in the home and rents out a room or an accessory unit) and non-owner-occupied short term rentals (where the entire unit is rented out with no resident owner), as defined under Boulder Revised Code Chapter 10-3.5 ^[1]. The distinction matters. Non-owner-occupied licenses are subject to zoning caps and neighborhood distribution limits in many parts of the city, while owner-occupied rentals generally face fewer restrictions. Boulder has, at various points, capped the total number of non-owner-occupied STR licenses citywide and by zone, so a license type that was available last year might be waitlisted or closed this year. Because license categories, caps, and eligible zone districts change as the city council revisits the ordinance, treat any specific cap number you find online as provisional. Confirm current license type availability and zoning eligibility with the City of Boulder's short term rental licensing office before you invest in setting up a listing.

How much does a Boulder short term rental license cost?

License fees vary by license type and are billed annually along with applicable sales, use, and lodging taxes that STR operators must collect and remit under Colorado's state lodging tax framework ^[2]. Because Boulder periodically adjusts its fee schedule, don't rely on a number you saw in an old blog post or forum thread. Budget for three cost categories: the license application/renewal fee itself, any inspection fee (some cities bundle this into the license fee, others bill separately), and ongoing tax remittance obligations (sales tax, use tax, and Boulder's accommodations or lodging tax, which applies to short-term stays). Confirm the current fee schedule, tax rates, and remittance frequency with the City of Boulder's finance and licensing offices directly, since these numbers change and this article won't guess at them. One cost that's easy to underestimate: bringing an older property up to current fire and building code for STR use. If your smoke detectors, egress windows, or electrical panel predate current code, expect repair or upgrade costs before you pass inspection, more than the license fee itself.

What inspections does a Boulder STR need to pass?

Short term rental licensing in Boulder, like most mandatory rental licensing programs, ties approval to a life-safety inspection. Inspectors typically check working smoke alarms in the right locations, carbon monoxide detectors near sleeping areas, a second means of egress from bedrooms, functioning locks, safe electrical panels, and a clear path to exits, consistent with the International Fire Code provisions Colorado municipalities commonly adopt for residential occupancies ^[3]. This mirrors the standard checklist used across most rental inspection programs nationally, where the goal is confirming the unit won't become a fire or carbon monoxide trap, not aesthetic code enforcement. If you want a broader sense of what inspectors nationwide actually check room by room, see what can a landlord look at during an inspection for the typical scope. Boulder may also require proof of adequate parking, posted occupancy limits, and a local contact person who can respond within a set time window if a neighbor calls in a complaint. Because STR units often turn over every few days, some cities also spot check for missing egress ladders in basement rentals or blocked fire exits from added furniture, so walk your unit like an inspector would before you schedule the actual visit.

How do I apply for a Boulder short term rental license?

The general process across most STR licensing cities, Boulder included, runs in a predictable order: confirm zoning eligibility for your address and desired license type, complete the license application with proof of ownership or authorization, schedule and pass the safety inspection, pay the license and any applicable tax registration fees, and post your license number on any listing you publish. Most platforms now require a license number at listing setup specifically because cities like Boulder have pushed for compliance verification. If you list before you have a license number, you risk the platform pulling your listing later, plus potential city fines for operating unlicensed. Build in lead time. Between scheduling an inspection, fixing anything that fails on the first pass, and waiting on staff processing, a first-time STR license can take several weeks from application to approved listing in cities with busy STR programs. Don't book your first guest until the license is actually issued, more than applied for.

How often does a Boulder STR license need to be renewed?

Most municipal STR licenses, including the structure Boulder uses, run on an annual cycle: you renew once a year, and renewal typically requires a fresh inspection or at minimum an updated affidavit that nothing material has changed at the property. Missing a renewal deadline can lapse your license, which means you have to stop taking bookings until it's reinstated. Set a calendar reminder 60 to 90 days before your renewal date. That gives you time to schedule a re-inspection if one is required and to fix anything that's degraded since your last inspection (a smoke detector battery, a door that no longer latches correctly, storage that's crept in front of an exit). If you're managing a rental license process for the first time, a simple document folder helps a lot here: keep your inspection report, license certificate, and any code correspondence together so renewal is a five-minute task instead of a scavenger hunt. This is the exact gap our $79 City Rental License & Inspection Prep Packet is built to close, walking you through what to gather and check before your city's inspector shows up.

What happens if I operate an unlicensed short term rental in Boulder?

Cities with mandatory STR licensing generally treat unlicensed operation as a code violation subject to civil citations, fines, and in repeat cases, orders to stop renting entirely. Boulder's municipal code enforcement process for rental violations typically starts with a notice of violation and a correction period, then escalates to fines if the property isn't brought into compliance, consistent with how Boulder Revised Code enforces licensing chapters generally ^[1]. Platforms complicate this. Boulder, like many STR-regulated cities, has worked with booking platforms to require a valid license number at listing, which means an unlicensed listing may get pulled by the platform itself even before the city acts. If you've received a violation notice, don't ignore it hoping it goes away. Contact the city licensing office listed on the notice, ask what specifically needs correcting, and get a written timeline for compliance. Most cities would rather get you licensed than fine you repeatedly, since the fine doesn't solve the underlying safety or zoning issue they're trying to fix.

How is a short term rental license different from a regular rental license?

A standard long-term rental license (the kind that applies when you rent to a tenant on a 6- or 12-month lease) usually has a lighter inspection cycle, often every 2 to 4 years depending on the city, because occupancy is stable and the tenant has ongoing legal rights to demand repairs. A short term rental license usually requires more frequent inspection and tighter zoning scrutiny because occupants turn over constantly and have none of the protections a long-term tenant has. The practical difference for you as an owner: an STR license ties into hotel-style regulation (occupancy limits, noise ordinances, local contact requirements, tax remittance) that a standard residential lease never triggers. If you're weighing whether to run a property as a long-term rental or an STR, understand that the STR path usually means more paperwork per year, not less, even though the nightly income might be higher. If you're new to the landlord side of this decision generally, our overview on what is a landlord and what is landlording walks through the basic legal role you're taking on either way, STR or long-term.

How do I become a landlord in the first place?

Becoming a landlord, whether you're renting long-term or running a short term rental, starts with confirming your property is legally allowed to be rented at your address (zoning, HOA rules, and any city license requirement), then setting up the business side: an LLC or personal name on title, a bank account for security deposits if your state requires separate holding, and landlord insurance (different from a standard homeowner's policy). After that, most new landlords need to register with their city's rental licensing office if one exists (many mid-size and large cities now require this), obtain any required inspection sign-off, and get familiar with their state's landlord-tenant statute for notice periods, security deposit limits, and eviction procedure. Skipping the licensing step is the single most common first-year mistake, because many owners don't realize their city requires registration until they get a violation notice. For a broader walk-through of the landlord role and its ongoing responsibilities, see landlord landlords and tenant rights, since understanding what tenants are entitled to is half of doing this job well.

Who is responsible for a rental property walk-through inspection in California?

In California, the landlord is responsible for conducting a move-in and move-out inspection and providing the tenant a written itemized statement of any deductions from the security deposit within 21 days of move-out, under California Civil Code Section 1950.5 ^[4]. The landlord must also, if requested, give the tenant a chance to fix any deficiencies before move-out by offering an initial inspection roughly two weeks before the tenancy ends. The statute is specific about this: California Civil Code Section 1950.5(f) requires that "the landlord shall notify the tenant in writing of his or her option to request an initial inspection of the premises" before the tenant vacates ^[4]. This gives the tenant a chance to correct issues (a stain, a hole in drywall) before final move-out, rather than getting surprised by deductions after the fact. This is separate from the city-level STR or rental licensing inspection covered above. California's move-in/move-out inspection rule applies statewide to any residential tenancy, while STR licensing inspections are a city-specific safety and zoning check tied to short term rental operation.

What can a landlord look at during a rental inspection?

During a routine or move-in/move-out inspection, a landlord can generally document the condition of walls, floors, fixtures, appliances, smoke and carbon monoxide detectors, plumbing, and any damage beyond normal wear and tear. What a landlord cannot do is use an inspection as a pretext to search a tenant's personal belongings, go through drawers or closets unrelated to the unit's condition, or conduct inspections without proper notice, which varies by state but is commonly 24 to 48 hours for non-emergency entry. For city-mandated rental licensing inspections (the kind covered throughout this article for Boulder STRs), the inspector is checking for code compliance items: working detectors, safe electrical and heating systems, adequate egress, and posted occupancy limits, not the tenant's cleanliness or decor choices. Landlords should give written notice before any inspection, whether it's a routine walk-through or a city-required licensing inspection, and should never enter without notice except in a genuine emergency (fire, flood, gas leak).

How much notice does a landlord have to give before entering?

Notice requirements vary significantly by state, so there's no single national answer. California requires 24 hours' written notice for non-emergency entry under Civil Code Section 1954, and treats that as reasonable notice unless the parties agree otherwise ^[4]. Many other states use a similar 24 to 48 hour standard, though some states don't specify a number at all and just require "reasonable notice." Check your specific state's landlord-tenant statute rather than assuming a number, because entry-notice rules are one of the most frequently cited sources of tenant complaints and small claims disputes. Emergency situations (active water leak, fire, gas smell, or a health and safety threat) are the standard exception that allows entry without advance notice in nearly every state. For STR operators specifically, remember that between-guest cleaning and turnover entries are generally not "tenant" entries in the legal sense since STR guests aren't tenants under most state landlord-tenant law, but any long-term component of your property (a resident manager's unit, a shared owner-occupied space) may still trigger standard notice rules.

What rights do tenants have without a written lease?

A tenant without a written lease still has full legal protection under their state's landlord-tenant law; the absence of a signed lease does not mean the tenant has no rights. Most states treat an unwritten rental arrangement as a month-to-month tenancy, which still requires the landlord to give proper notice before ending the tenancy (commonly 30 days, though this varies by state and by how long the tenant has lived there), to maintain habitable conditions, and to return any security deposit according to state deposit law. What changes without a written lease is mainly the evidentiary picture: rent amount, due date, and any specific rules (pets, subletting, guests) become harder to prove if there's ever a dispute, since there's no signed document to point to. That's exactly why most landlord advocates recommend always using a written lease, even a simple one, rather than relying on a verbal agreement. For tenants wondering what protections apply in this situation, see tenants rights and renters rights for a broader look at habitability, deposit return, and notice requirements that apply regardless of lease format.

Why do landlords require renters insurance?

Landlords require renters insurance mainly to shift liability and property-damage risk away from the landlord's own policy. A landlord's property insurance covers the building itself, but it generally does not cover a tenant's personal belongings (electronics, furniture, clothing) if there's a fire, burst pipe, or theft, and it may not fully cover liability if a tenant's guest is injured in the unit. Renters insurance policies are inexpensive relative to the coverage they provide (commonly in the range of roughly $15 to $30 a month depending on coverage level and location, though this varies by market and insurer), which is part of why so many landlords now require proof of an active policy as a lease condition. Requiring it also reduces the odds that a tenant sues the landlord over damaged belongings the landlord's policy was never meant to cover. For STR operators, the insurance picture is different: most homeowner policies exclude short term rental use entirely, so STR hosts generally need a specific short term rental or landlord policy rider, and some booking platforms include limited host protection coverage that is not a substitute for a real policy. Check your platform's host guarantee terms carefully; most explicitly state they are not insurance.

What can't a landlord do in Ohio?

Under Ohio Revised Code Chapter 5321, a landlord cannot shut off a tenant's utilities, change the locks, or remove the tenant's belongings to force them out, a practice generally called a "self-help eviction." Ohio law requires landlords to go through the formal eviction process in court (a forcible entry and detainer action) rather than taking matters into their own hands, no matter how far behind on rent the tenant is ^[5]. Ohio Revised Code Section 5321.15 specifically prohibits a landlord from recovering or taking possession of a rental unit by "willful diminution of services to the tenant, including, but not limited to, interruption or reduction of water, heat, electric, gas, elevator, or other essential service" ^[5]. Violating this section can expose the landlord to the tenant's actual damages plus, in some cases, statutory damages and attorney fees. Ohio landlords also cannot enter a rental unit without giving the tenant reasonable notice, generally interpreted as 24 hours except in emergencies, and cannot retaliate against a tenant for reporting a code violation or joining a tenant organization, both of which are addressed elsewhere in Chapter 5321 ^[5].

Frequently asked questions

Does Boulder cap the number of short term rental licenses?

Boulder has historically capped non-owner-occupied STR licenses by zone district as part of its ordinance, with owner-occupied licenses facing fewer restrictions. Caps and eligible zones change as the city council revisits the program, so confirm current availability with the City of Boulder's short term rental licensing office before assuming a license slot is open.

Can I run a short term rental in any Boulder zone district?

No. Boulder restricts short term rental licensing by zone district and license type, and some residential zones may not allow non-owner-occupied STRs at all. Confirm zoning eligibility for your specific address with the City of Boulder before you invest in setting up a listing or scheduling an inspection.

Do I need a Boulder STR license if I only rent occasionally?

Yes. Boulder's licensing requirement applies to any dwelling rented for fewer than 30 consecutive days, regardless of how often you rent it out. Occasional hosts (a few weekends a year) still need a license under the same ordinance that governs full-time STR operators.

How long does it take to get a Boulder STR license approved?

Timelines vary by application volume and whether your property passes inspection on the first try, but budget several weeks from application to approved license in cities with active STR programs. Don't accept bookings until the license is actually issued, since booking before approval risks fines for operating unlicensed.

How to become a landlord for the first time?

Confirm your property can legally be rented (zoning, HOA rules, city license requirements), get landlord insurance, learn your state's landlord-tenant statute for notice and deposit rules, and register with your city's rental licensing office if one exists. Many first-year landlords miss the licensing step and only find out when they get a violation notice.

What is landlording?

Landlording is the ongoing job of owning and managing rental property: collecting rent, maintaining habitability, handling repairs, managing tenant turnover, and complying with state landlord-tenant law and any local rental licensing or inspection requirements. It's a legal role with real obligations, more than a source of passive income.

What is a landlord legally responsible for?

A landlord is legally responsible for keeping the rental unit habitable (working plumbing, heat, structural safety), following state and local law on notice, deposits, and entry, and complying with any city rental licensing or inspection program. Exact duties vary by state statute and local ordinance.

Who is responsible for a rental property walk-through inspection in California?

The landlord is responsible for conducting move-in and move-out inspections and providing an itemized deposit deduction statement within 21 days of move-out, under California Civil Code Section 1950.5. The landlord must also offer the tenant an optional pre-move-out inspection roughly two weeks before the tenancy ends.

What rights do tenants have without a lease?

A tenant without a written lease is usually treated as a month-to-month tenant under state law, still entitled to proper notice before eviction, habitable conditions, and lawful deposit handling. The lack of a written lease mainly makes rent terms and rules harder to prove in a dispute, not absent.

Why do landlords require renters insurance?

Landlords require renters insurance because their own property policy typically doesn't cover a tenant's personal belongings or certain liability claims. Requiring an active renters policy (commonly $15 to $30 a month) shifts that risk to the tenant and reduces disputes over damaged belongings after a fire or leak.

How much notice does a landlord have to give before entering a unit?

It depends on the state. California requires 24 hours' written notice for non-emergency entry under Civil Code Section 1954. Many states use a similar 24 to 48 hour standard, though exact language varies, so check your state's specific landlord-tenant statute rather than assuming a number.

What can't a landlord do in Ohio?

Under Ohio Revised Code Section 5321.15, a landlord cannot shut off utilities, change locks, or remove belongings to force a tenant out (self-help eviction). Ohio landlords must use the formal court eviction process and give reasonable entry notice, generally 24 hours except in emergencies.

Can I list my Boulder STR on Airbnb before I have a license?

You shouldn't. Most platforms now require a valid city license number at listing setup, and Boulder can fine operators for advertising or renting without a license. Get your license approved first, then post the listing with the license number included as required.
