Can You Legally Run a Short-Term Rental in Tuolumne County?

Can you legally run a short-term rental in Tuolumne County?

Yes. Short-term rentals are permitted in the unincorporated areas of Tuolumne County — which covers Twain Harte, Mi Wuk Village, Soulsbyville, Long Barn, and surrounding communities. As of January 19, 2024, all STR operators must hold a valid Transient Occupancy Tax (TOT) Certificate and pass a biennial Fire and Life Safety Inspection conducted by the Tuolumne County Fire Department. Without both, operating a short-term rental is unlawful under Ordinance Code Chapter 8.70.

I get this question a lot — usually from buyers who've already fallen in love with a cabin in Mi Wuk Village or Twain Harte and are running the numbers in their heads before we even write the offer. And the good news is: yes, short-term rentals are absolutely allowed up here. But "allowed" and "compliant" are two different things, and the gap between them has gotten a lot more defined since January 2024.

Tuolumne County passed its STR ordinance by a 5-0 Board of Supervisors vote in December 2023, and it went into effect the following month. If you're looking at a cabin in Twain Harte, a ranch in Sonora or a home in Mi Wuk Village as an investment property — or if you already own one and are wondering where you stand — this is the post to bookmark.

📋 What the Law Actually Requires

Short-term rentals in Tuolumne County are defined as residential units rented for 30 days or less. That's a broad definition — it covers single-family cabins, A-frames, condos, secondary units, guesthouses, and even individual bedroom rentals. If you're renting it for less than a month on Airbnb, VRBO, or any other platform, this ordinance applies to you.

Here's what you need to operate legally:

1️⃣ Transient Occupancy Tax (TOT) Certificate

Your starting point. Register through the Tuolumne County Tax Collector's office. The TOT rate is 12% of the rent charged — your responsibility to collect and remit quarterly.

Important: Airbnb collects and remits TOT on behalf of Tuolumne County automatically. VRBO does not. If you're using VRBO or direct booking, you are responsible for reporting all revenue on your quarterly return.

2️⃣ Fire and Life Safety Inspection

This is the one that surprises people. Effective January 19, 2024, you must pass a fire and life safety inspection conducted by the Tuolumne County Fire Department before you can legally operate — and it renews every two years. Application fee: $300 (nonrefundable), paid through the county's online portal.

The inspection covers:

🔥 Smoke alarms in every bedroom and on every level
💨 Carbon monoxide detectors outside each sleeping area where gas appliances or fireplaces are present
🧯 A 5-pound 2-A:10-B:C fire extinguisher near the kitchen (one per level for multi-story properties), inspected annually
🌲 Defensible space compliance under California Public Resources Code 4291
🏠 Visible street address identification meeting county code standards

3️⃣ Local Contact Person

You must designate a local contact available 24/7 by phone who can be on-site within 60 minutes. This can be a property management company, a neighbor, or you — if you live within 60 minutes. This information must be posted inside the rental.

4️⃣ Interior Posting Requirements

Guest-facing contact information and an emergency evacuation plan must be posted inside the unit.

That's the compliance picture as of 2026. It's not overwhelming — but it does require a checklist mindset before you put your first listing live.

📍 Does This Apply to Every Community?

Tuolumne County's STR ordinance covers the unincorporated areas of the county. That's where most of our mountain communities sit — Twain Harte, Mi Wuk Village, Strawberry, Long Barn, Soulsbyville, Tuolumne, and Sonora (the community, not the city).

⚠️ The City of Sonora operates under its own jurisdiction. If you're looking at a property within Sonora's city limits, confirm directly with the city regarding STR rules — those aren't covered by the county ordinance.

For the vast majority of mountain cabin and second-home buyers I work with, this distinction is a non-issue. The properties that pencil as STR investments are almost always in the unincorporated areas — which means you're working within the county framework, and you know exactly what the rules are.

💰 What This Means If You're Buying for STR Income

If you're purchasing a property in Twain Harte, Mi Wuk, or Pinecrest with the intention of running it as a short-term rental, here's what I tell every buyer before we start touring:

Budget the compliance costs. The $300 fire inspection application fee is required upfront. The biennial renewal is ongoing. Factor in any property upgrades needed to pass inspection — older cabins may need updated smoke/CO detectors or fire extinguishers.

Confirm existing compliance if buying a current STR. If the seller is already operating an STR, ask for documentation: the current TOT certificate number, proof of a passed fire inspection, and the inspection date. Inspections are good for two years — if it's approaching renewal, that's a negotiating point.

Know your platform's tax obligations. Airbnb handles the county TOT automatically. Every other platform — VRBO, Hipcamp, direct booking — puts the collection and remittance on you. Your quarterly return goes to the Tuolumne County Tax Collector.

Run your numbers with occupancy data, not assumptions. There are over 1,100 STR-certified properties in Tuolumne County. That's a healthy market with real demand — Airbnb alone lists more than 1,000 cabins in the area. But performance varies significantly by community, property type, amenities, and season. Before you make an offer, I can help you pull comparable rental income data so you're underwriting with real numbers.

The specific return potential of any property depends on condition, location within the county, bedroom count, amenities (hot tub, pet-friendly, ski proximity), and how aggressively you manage your listing. That's a conversation worth having before you're in escrow, not after.

❓ Frequently Asked Questions

Do I need a permit to run a short-term rental in Twain Harte, Mi Wuk Village or Tuolumne County?

Yes. All STRs in the unincorporated areas of Tuolumne County — including Twain Harte and Mi Wuk Village — require a Transient Occupancy Tax (TOT) Certificate from the county Tax Collector and a passed Fire and Life Safety Inspection from the Tuolumne County Fire Department. The inspection costs $300 to apply and renews every two years. Operating without both is unlawful under county Ordinance Code Chapter 8.70.

What is the Transient Occupancy Tax rate in Tuolumne County?

The TOT rate is 12% of the rent charged per stay. Airbnb collects and remits this tax automatically on behalf of Tuolumne County hosts. If you're using VRBO or taking direct bookings, you're responsible for collecting the tax from guests and filing a quarterly return with the county Tax Collector's office.

What happens if I operate an STR without passing the fire inspection?

Operating without a passed inspection is a violation of Tuolumne County Ordinance Code Chapter 8.70 and subjects the property owner to penalties. Anyone advertising a short-term rental without a valid inspection can be cited. Contact the Fire Prevention Division at (209) 533-5502 or fireprevention@co.tuolumne.ca.us to get on the inspection schedule.

Does the STR ordinance apply to the City of Sonora?

No — Sonora is an incorporated city with its own jurisdiction, and the county STR ordinance covers unincorporated areas only. If you're considering a property within Sonora city limits for use as a short-term rental, contact the City of Sonora directly for any applicable rules.

🏔️ Ready to Run the Numbers?

The STR market in Tuolumne County is real, active, and legally accessible — but only if you go in with clear eyes about what compliance actually looks like. Whether you're a buyer evaluating a cabin as an investment property or an existing STR owner making sure you're fully squared away, I'm happy to walk you through it.

I've been here my whole life. I know which communities attract the strongest short-term rental traffic, which property types perform, and what to look for in due diligence when you're buying specifically for income potential.
