Can I Airbnb My Denver Home? The Real Rules, the Real Math, and What Most Buyers Get Wrong

Every buyer who hears about house hacking eventually asks the same question: can I just Airbnb part of this place? It's a reasonable thought. Denver gets a lot of visitors, nightly rates are solid, and the idea of offsetting your mortgage with Airbnb income is genuinely appealing.

The honest answer is: yes, you can — but the rules are specific enough that most buyers don't fully understand what they're signing up for. And the math is different than most people expect.

Here's the real picture.

Denver's STR Rules in Plain English

Denver defines a short-term rental as any lodging stay under 30 consecutive days. To operate one legally, you need two separate licenses from the city:

A General Business License, which registers your rental as a taxable business with Denver, and a Short-Term Rental License from the Department of Excise and Licenses, which specifically authorizes you to rent out your home for short stays. The STR license runs $100 per year and must be renewed annually.

The critical piece that many buyers miss: Denver's ordinance requires that the property be your primary residence. Not a second home. Not an investment property. The place where you actually live — evidenced by your driver's license, voter registration, or utility bills showing that address. You are allowed exactly one STR license because you can only have one primary residence.

That means you cannot buy a property, move somewhere else, and list the whole thing on Airbnb. The intent of Denver's STR rules is to allow homeowners to monetize their existing homes — not to create a parallel class of short-term rental investment properties.

A few other requirements: you need at least $1 million in liability insurance coverage, and your property must pass a safety inspection covering fire alarms, carbon monoxide detectors, and emergency exit routes before a license is issued. Fines for operating without a license start at $999 per violation.

The Density Cap — Why Your Specific Block Matters

Here's where it gets more localized. Denver has a density cap: no more than 3% of residential units within any given census block can hold active STR licenses at the same time.

In neighborhoods like RiNo, LoHi, and Capitol Hill — where STRs have been popular for years — that cap is already hit in many census blocks. If you buy a home on one of those blocks, you may not be able to get a license at all, regardless of how well your property would perform as a rental.

This is worth checking before you make an offer on any property where STR income is part of your financial plan. The Denver Department of Excise and Licenses maintains data on license density by area, and your agent should be able to help you look up a specific block before you're under contract.

The Actual Income Math

Denver's STR market is real. There are roughly 2,400 active listings, and the city consistently draws business travelers, outdoor tourists, and event visitors year-round. But the income numbers look different once you account for everything.

Here's a realistic breakdown for a 1-bedroom whole-unit listing:

For a 2-bedroom, bump the nightly rate to ~$180, run the same math, and you land around $2,000–$2,200/month net.

Those are real numbers. But compare them to what a long-term tenant pays for a 1-bedroom in Denver right now — typically $1,600–$1,900/month — and the gap between STR and traditional rental is narrower than most buyers assume. The long-term rental also means no per-stay cleaning, no platform management, no guest communications, and far fewer headaches.

STR wins when you can push occupancy above 65% — which tends to happen in tourist-heavy locations close to downtown, Union Station, or major venues. For a home in Congress Park or Green Valley Ranch, the long-term tenant math often comes out ahead once you factor in your time.

The Lending Problem Nobody Mentions Until It's Too Late

Here's the piece that trips up buyers who are planning their purchase around STR income: lenders won't count it when you're qualifying for the mortgage to buy the home.

Fannie Mae requires 12–24 months of documented short-term rental history — reflected on your IRS Schedule E — before that income can be used in underwriting. A new listing has zero history. So if your plan is "I'll Airbnb the spare bedroom to help me qualify for more house," that plan doesn't work on a conventional loan.

Long-term rental income is different. If you have a documented lease and a history of receiving rent, most lenders will count 75% of that income toward your DTI. Short-term rental income just doesn't get that treatment until you've been running the listing long enough to show a track record.

This matters most for buyers who are stretching on purchase price and relying on rental income to make the numbers work. Build your qualification around what you earn today, and treat STR income as upside — not a foundation.

When STR Actually Makes Sense

None of this means short-term renting is a bad idea. It means it works better in specific situations:

If you're buying a home with a separate ADU or basement suite and you intend to live in the main unit, that's the strongest setup. You're compliant with the primary residence rule, you have a genuinely separate space to offer guests, and you're not giving up your own home's livability to make it work.

If you're buying near downtown Denver — within walking distance of Ball Arena, Union Station, or the convention center — occupancy runs higher and nightly rates respond better to events. The math gets more favorable.

If you're committed to managing it actively (or hiring a local STR co-host), there's real upside. But passive income this is not. Denver's best-performing STRs are run by hosts who treat it like a business — responsive messaging, professional cleaning, consistent quality.

The Short Version

Denver allows short-term rentals, but only at your primary residence, only with a city license ($100/year), and only where your census block isn't already at the 3% density cap. Net income after taxes and costs runs about $1,500–$2,200/month for a 1–2 bedroom listing — similar to a long-term tenant, with more management involved. And that income won't help you qualify for the mortgage to buy the place.

If Airbnb income is part of why a home makes financial sense to you, check the density cap on the specific address before you fall in love with it.
