7 Important Facts That You Should Know About Short-Term Rentals

The short-term rental (STR) landscape is evolving faster than ever. Whether you’re a seasoned host with multiple properties or a homeowner thinking about renting out a spare room, 2026 is bringing significant changes to the industry. From new tax rules and insurance pitfalls to shifting market trends, staying informed is key to protecting your investment and maximizing your income.

To help you navigate this complex terrain, we’ve compiled seven crucial facts you need to know about short-term rentals right now.

1. The Definition of “Short-Term” Varies by Location

Before you list your property, you need to know how your local jurisdiction defines a short-term rental. While it might seem straightforward, the legal definition can change depending on where you live. For instance, Maine’s Land Use Planning Commission defines a short-term rental as a dwelling unit rented for a period of less than 30 consecutive calendar days . However, in the Central Okanagan in Canada, proposed regulations define it as a stay of 90 days or less . Understanding your local definition is the first step toward compliance, as it dictates which rules and permit requirements apply to your activity.

2. The Market is Booming—and Becoming More Professional

The short-term rental market is not just a side hustle anymore; it’s a major economic force. The global short-term rental market was valued at a staggering $133.85 billion in 2025 and is projected to nearly triple to $377.66 billion by 2035 . This growth is driven by changing traveler preferences, with nearly 62% of travelers opting for the flexibility of STRs over traditional hotels . This signals a shift toward a more professional and competitive landscape where guest experience is paramount.

3. Your Taxes Are More Complicated Than You Think (Especially the “14-Day Rule”)

The tax code treats short-term rentals differently than long-term leases. A key fact for casual hosts is the “Augusta Rule” (IRC §280A(g)). If you rent out your personal residence for 14 days or less per year, the income is entirely tax-free . However, once you exceed that threshold, your rental is treated as a taxable activity. Furthermore, if you rent a property for an average of seven days or less and provide substantial services (like daily housekeeping), the IRS may classify it as a business rather than a passive rental, subjecting you to self-employment tax but also opening doors for the 20% Qualified Business Income (QBI) deduction .

4. Standard Home Insurance Likely Won’t Cover You

Assuming your regular homeowner’s policy protects you is one of the biggest and most costly mistakes a host can make. Standard home and landlord policies are typically not designed for the frequent guest turnover of a short-term rental and often exclude claims related to business or income-producing activities . If a guest is injured on your property or causes damage, your claim could be denied. You need specialized short-term rental insurance, which typically includes public liability, coverage for guest-related damage, and loss of income. Some states, like Arizona, are even mandating minimum liability coverage, requiring owners to maintain at least $500,000 in aggregate liability insurance .

5. Regulation is Everywhere (and It’s Getting Tighter)

Gone are the days of the “Wild West” in the STR world. Governments at all levels are cracking down. Many locations now require hosts to register with local authorities. For example, New York State law mandates that short-term rental hosts register their units and adhere to strict safety standards, including posting evacuation diagrams and having a working fire extinguisher . In Maine, operators must file a notice with the Land Use Planning Commission, with existing operators given 180 days to comply . Failing to register can result in fines or being forced to cease operations.

6. Cities Are Using STR Taxes to Fund Affordable Housing

As the STR market grows, so does the scrutiny from local governments looking for revenue streams to tackle pressing issues like housing affordability. Across the United States, new taxes are being proposed and implemented specifically for short-term rentals. In San Diego, a proposal seeks to impose an annual tax of $5,000 per bedroom on STRs to fund affordable housing . Similarly, Washington state has enacted a 6% special excise tax on short-term rentals facilitated by online platforms, with the revenue directed toward affordable housing programs .

7. There’s a Push for State-Level Preemption

While local regulations are tightening, there’s also a significant counter-movement happening at the state level to limit how much local cities and counties can restrict short-term rentals. Lawmakers in states like Kentucky and Arizona are proposing or enacting laws that preempt local government control. For instance, a Kentucky bill aims to prohibit local governments from imposing residency requirements or density-based restrictions on STRs . In Arizona, cities are explicitly prohibited from banning short-term rentals outright, ensuring they remain a legal use of property . This patchwork of laws means hosts must be aware of both local and state rules.
