Welcome to the Grand Welcome Mammoth Lakes Blog

A successful Mammoth Lakes vacation rental begins before the first listing goes live. Owners need to confirm that transient use is permitted, complete the Town's property certification process, register for business and lodging taxes, and build a mountain-ready operating plan.

This guide was reviewed on August 1, 2026. Programs, fees, zoning interpretations, and property approvals can change, so verify the address with the Town of Mammoth Lakes or Mono County before relying on a general market guide.

First confirm which government regulates the property

A Mammoth Lakes mailing address does not always prove that a home is inside Town limits. Properties within the Town generally follow the Town's zoning, Certified Property Program, business-tax, TOT, and TBID rules. Unincorporated Mono County has a different short-term-rental program, including county land-use and annual activity permits.

Check the parcel and jurisdiction first. Then review any condominium declaration, master plan, or homeowners-association rules, which may be stricter than local government rules.

Is transient rental use allowed?

Zoning is the first eligibility test. The Town's Guide to Zoning for Transient Use says transient use is generally allowed in RMF-2, commercial, resort, and certain specific-plan zones. It is generally prohibited in RMF-1, single-family, and rural residential zones. Measure Z preserves the prohibition in single-family residential areas.

Do not assume that a nearby condo's rental activity proves eligibility for another parcel. Confirm the zoning designation, governing plan, prior approvals, and private covenants before purchasing or advertising.

CPAN and the Certified Property Program

For eligible properties inside Town limits, a Certified Property Authorization Number (CPAN) is required before advertising or renting stays shorter than 31 days. Each property needs its own number. The authorization is annual and does not transfer to a new owner.

The Town's current Certified Property Program information states that certification includes a Town-approved inspection initially and every four years, plus reinspections when specified events occur. The published annual CPAN fee was $250 when this guide was reviewed; confirm the current fee before applying.

Listings must display the properly formatted CPAN and the property's maximum occupancy. The standard occupancy formula is two guests per bedroom plus two. A loft counts only if it meets inspection and code requirements. The inspection program addresses smoke and carbon-monoxide alarms, extinguishers, propane detection where applicable, evacuation information, parking, trash, snow management, and a 24-hour contact.

Owners may authorize a property manager to apply, but the owner remains responsible for ensuring the property is eligible and compliant.

Taxes and reporting

Town operators also need a Business Tax Certificate and must report Transient Occupancy Tax and Tourism Business Improvement District assessments. When reviewed, the Town published a 13% TOT on rent and required guest-paid charges, and a 1% lodging TBID assessment on gross short-term room-rental revenue. Current definitions and filing instructions are available from the Town's TOT information and TBID information.

Platform collection does not automatically resolve every owner filing obligation. Reconcile direct bookings, platform bookings, taxable fees, exemptions, and zero-return periods against the current Town instructions.

Mountain operations require more than a permit

Mammoth's snow, freeze-thaw cycles, altitude, wildfire exposure, and winter access make preventive care central to guest safety and asset protection. A strong plan includes:

• snow-removal coverage for drives, walkways, decks, vents, meters, and approved parking areas;
• roof, heat-trace, ice-dam, drainage, and exterior-envelope inspections;
• remote temperature and leak monitoring with a documented local response plan;
• tested heat, hot-water, fireplace, smoke, carbon-monoxide, and propane systems;
• backup access procedures when roads, locks, power, or internet fail;
• guest instructions for chains, parking, snow storage, trash, bears, fireplaces, and altitude;
• seasonal defensible-space and smoke-readiness reviews;
• pre-arrival inspections after severe weather or extended vacancy.

The most expensive failures often begin as small issues: a frozen line, blocked vent, dead thermostat battery, unreported roof leak, or snow-buried parking marker. Response speed matters.

Questions to ask a Mammoth Lakes property manager

Before signing an agreement, ask:

1. How do you verify zoning, CPAN, inspection, business-tax, TOT, and TBID status?
2. Who is the 24-hour local contact, and what happens when the primary contact is unavailable?
3. Which snow, plumbing, HVAC, electrical, roofing, and restoration vendors provide after-hours coverage?
4. How are occupancy and parking limits kept consistent across every channel?
5. What inspection occurs before each arrival and after major storms?
6. How are platform-collected and direct-booking taxes reconciled?
7. Which services are included in the fee, and which maintenance costs are passed through?

Owner readiness checklist
