Short-Term Rental (STR)
A short-term rental (STR) is a furnished residential property rented to guests for fewer than 30 consecutive days. Commonly listed on platforms like Airbnb and Vrbo, STRs include entire homes, condos, apartments, and private rooms that give travelers an alternative to hotels while giving property owners a higher-yield, flexible income stream — one governed by a distinct set of permits, taxes, and zoning rules that do not apply to standard long-term leases.
Key Takeaways
- An STR is any furnished property rented for fewer than 30 consecutive days, though the exact threshold — 28 days, 14 days — varies by jurisdiction
- The sub-30-day classification triggers specific permit, tax, and zoning requirements separate from landlord-tenant law
- Most cities require an STR permit and collection of transient occupancy tax (TOT) to operate legally
- STR performance is measured by occupancy rate, ADR, and RevPAR — metrics that vary sharply across regulatory environments
- Zoning regulations and HOA restrictions can limit or prohibit STRs regardless of state or city law
What Defines a Short-Term Rental
The 30-day rule is the most common legal threshold, but it is not universal. New York City's Local Law 18 defines short-stay as fewer than 30 consecutive days, while some municipalities use 28 days (matching calendar months) or even 14 days as the cutoff. The critical point is that once a rental crosses that threshold, it shifts from the short-term regulatory framework into standard landlord-tenant law — which means different taxes, different eviction rules, and different insurance requirements.
Three elements define an STR across virtually every jurisdiction:
- Duration — fewer than the local threshold (typically 30 days) per stay
- Compensation — money, services, or anything of value exchanged for use of the space
- Residential property — a home, condo, apartment, or room, as opposed to a commercial hotel
Some cities further distinguish by whether the owner is present (owner-occupied vs. non-owner-occupied), which determines which permit tier applies and how strictly the property is regulated.
Types of Short-Term Rentals
STRs come in several forms, each carrying different regulatory implications:
| Type | Description | Typical Regulations |
|---|---|---|
| Entire home | Full property rented while owner is away | Often requires STR permit; may face night caps |
| Owner-occupied | Owner lives on-site during guest stays | Usually lighter restrictions; sometimes exempt from permits |
| Non-owner-occupied | Investment property with no owner present | Strictest regulations; may require conditional use permit |
| Private room | Single room in shared living space | Often treated as owner-occupied; lighter regulation |
STR vs. Long-Term Rental: Key Differences
| Factor | Short-Term Rental | Long-Term Rental |
|---|---|---|
| Lease length | Under 30 days per stay | 6–12+ months |
| Furnishing | Fully furnished required | Usually unfurnished |
| Nightly rate | Higher — market-dependent | Lower monthly equivalent |
| Income consistency | Variable by season | Stable monthly rent |
| Management effort | High (turnover, cleaning, guest communication) | Low (monthly rent collection) |
| Tax obligations | TOT + income tax | Income tax only |
| Permits required | STR permit, business license | Standard landlord registration |
| Insurance | STR liability insurance | Landlord insurance |
| Regulatory risk | High — rules shift frequently | Low — landlord-tenant law is stable |
How Regulation Reshapes STR Markets
STR classification is not neutral. Calling a rental "short-term" is what activates the regulatory apparatus — permits, taxes, night limits, zoning overlays — and the stringency of that apparatus varies enough to reshape an entire city's supply.
The most powerful variable in STR market selection is not ADR or occupancy — it's the regulatory environment that determines whether you can operate at all.
STR Revenue Potential by Market
Annual STR earnings vary sharply with market conditions and regulatory environment. AirROI's trailing-12-month median figures across active listings:
| Market | Annual Revenue | Occupancy | ADR | Regulatory Regime |
|---|---|---|---|---|
| San Diego, CA | $53,472 | 53% | $394.90 | Moderate |
| Gatlinburg, TN | $50,438 | 47% | $376.50 | Light |
| Scottsdale, AZ | $49,153 | 49% | $421.10 | Light |
| Nashville, TN | $44,039 | 47% | $353.60 | Moderate |
| Miami, FL | $34,738 | 49% | $291.00 | Moderate |
| New York, NY | $21,970 | 49% | $224.70 | Heavy |
The New York figure captures a market where the STR is functionally a medium-term rental — hosts can legally serve 30-day-plus stays, but true nightly STR operation is largely prohibited. The $21,970 median understates what comparable properties earn in light-regulatory markets operating as genuine short-stays.
Operating a Short-Term Rental Legally
Getting into the STR business requires working through several regulatory layers before the first guest books:
- Research local regulations — check your city's STR regulations, zoning laws, and HOA rules before purchasing or listing
- Obtain required permits — apply for your STR permit and business license; some markets have waitlists or caps
- Set up tax collection — register to collect and remit transient occupancy tax; many platforms remit automatically, but verify
- Secure proper insurance — get STR liability insurance — standard homeowner's policies typically exclude commercial short-stay activity
- Analyze the market — use data tools to understand local occupancy rates, ADR, and competitive supply before committing capital
Frequently Asked Questions
A short-term rental is a furnished residential property rented to guests for fewer than 30 consecutive days. The exact threshold varies by jurisdiction — some cities use 28 days, others 14. Most STRs are listed on Airbnb, Vrbo, or Booking.com, and the sub-30-day definition is what triggers permit, tax, and zoning requirements distinct from standard landlord-tenant law.
In most cities and counties, yes. The majority of popular STR markets require hosts to obtain an STR permit or business license, register with the local government, and collect transient occupancy tax. Requirements vary widely by jurisdiction — always verify local rules before listing, because non-compliance can result in fines, forced delisting, and back taxes.
Short-term rentals are furnished properties rented for under 30 days at higher nightly rates but with variable occupancy, while long-term rentals are leased for months or years at lower but stable monthly rates. STRs carry different tax obligations (transient occupancy tax), insurance requirements, and regulatory frameworks — including permits and night caps that long-term rentals don't face.
Annual STR revenue varies significantly by market and property type. AirROI's trailing-12-month data shows median annual revenue ranging from about $22,000 in tightly regulated New York City to over $53,000 in San Diego and $50,000 in Gatlinburg, TN. Market selection, regulatory environment, and amenities are the primary drivers of earnings potential.
Yes, in most markets — and owner-occupied STRs are often subject to lighter regulation than investment-property STRs. Many cities allow home-sharing in a primary residence with fewer restrictions or permit exemptions. Check whether your jurisdiction requires a primary-residence declaration and whether HOA rules permit it, as private community restrictions layer on top of municipal law.
