Big Bear Lake is one of Southern California's most popular mountain destinations. Located in the San Bernardino Mountains at over 6,700 feet, the area draws skiers and snowboarders to Snow Summit and Bear Mountain in winter, and families to the lake for boating, hiking, and mountain biking in summer. If you operate a cabin rental on Airbnb, VRBO, or through direct bookings, you face a layered tax structure at the state, county, and city level — plus mountain-specific operating costs that set Big Bear apart from lowland rental markets.
California State Income Tax
Unlike states with no income tax, California imposes a progressive state income tax on your net STR rental income. Rates range from 1% to 13.3% at the top bracket, making California one of the highest-taxed states in the country for rental income. Your Big Bear STR profits are taxed at your marginal state rate on top of federal income tax (plus self-employment tax if filing Schedule C). This makes maximizing every deductible expense — depreciation, maintenance, supplies, mileage — critical for Big Bear hosts. Every dollar you fail to deduct is taxed at both the federal and California state level.
Transient Occupancy Tax (TOT)
Big Bear cabin rentals are subject to transient occupancy tax at two levels. San Bernardino County imposes a county TOT on short-term accommodations, and the City of Big Bear Lake levies its own city TOT on top of that. The combined effective TOT rate on short-term rentals in Big Bear Lake is significant and among the higher rates in mountain resort communities.
Airbnb and VRBO collect and remit TOT in many California jurisdictions, but you should verify your specific obligations with both the City of Big Bear Lake and San Bernardino County. If you accept direct bookings outside of platforms, you are responsible for collecting and remitting TOT yourself. Failure to register and remit can result in penalties and back taxes.
Big Bear Lake Vacation Rental Permit Requirements
No credit card required
The City of Big Bear Lake requires a vacation rental permit for all short-term rental properties. The permit process includes a property inspection to verify compliance with safety, occupancy, and parking requirements. You must maintain adequate insurance, display your permit number on all listings, and comply with noise and occupancy limits.
Permits must be renewed annually, and permit fees are a deductible business expense. The city actively enforces permit requirements — operating without a valid permit can result in fines and loss of rental privileges. Big Bear Lake has also established rules around maximum occupancy per property, quiet hours, and trash management. Check the City of Big Bear Lake's vacation rental program page for current requirements and application procedures.
Mountain Cabin Maintenance Deductions
Big Bear hosts face a category of operating expenses that lowland Airbnb operators simply do not encounter. These mountain-specific costs are fully deductible business expenses when your cabin is used exclusively as a rental, and they can add up to thousands of dollars per year.
Snow removal. Big Bear receives significant snowfall from November through March. Regular snow removal from driveways, walkways, decks, and roofs is essential for guest safety and access. Whether you hire a snow removal service or purchase your own equipment (snowblower, shovels, ice melt), these costs are deductible. Service contracts are expensed in the year paid; equipment over $2,500 can be depreciated or expensed under Section 179.
Roof maintenance from snow load. Heavy snow accumulation stresses roofing structures. Roof raking to prevent ice dams, structural inspections, and repairs caused by snow load are all deductible maintenance expenses. If you need a full roof replacement, that is a capital improvement subject to depreciation over 27.5 years (or accelerated with a cost segregation study).
Heating costs and propane. Mountain cabins require substantial heating from October through April. Propane is the primary fuel source for most Big Bear cabins, and winter propane bills can run $300-600+ per month during peak cold. Propane, natural gas, and electricity for heating are all deductible utility expenses. Pre-season furnace servicing is a deductible maintenance cost.
Chimney maintenance. Many Big Bear cabins feature wood-burning fireplaces or stoves — a major draw for guests seeking a mountain experience. Annual chimney inspections, cleaning, and creosote removal are required for safety and are fully deductible. Chimney cap replacements and flue repairs are also deductible maintenance expenses.
Fire Mitigation and Defensible Space
Big Bear is located in a high fire severity zone. California law and local ordinances require property owners to maintain defensible space around structures — typically clearing brush, dead vegetation, and combustible materials within 100 feet of the cabin. This is not optional; it is a legal requirement enforced by CAL FIRE and local fire agencies.
Tree removal and trimming. Removing dead trees, trimming branches that overhang the roof, and thinning dense vegetation are common annual expenses for Big Bear hosts. Professional tree removal in mountain areas can cost $500-3,000+ per tree depending on size and access difficulty. These costs are deductible as ordinary maintenance expenses when maintaining defensible space compliance.
Brush clearing and weed abatement. Hiring crews to clear brush and create defensible space zones is a fully deductible operating expense. Many hosts schedule this annually in late spring before fire season. Document these expenses carefully — they are legitimate, necessary costs of operating a mountain STR.
Ski Season vs. Summer Lake Season
Winter season (November - March). Snow Summit and Bear Mountain draw skiers and snowboarders from the greater Los Angeles area, just a two-hour drive away. Winter weekends command premium nightly rates, and holiday weeks (Christmas, New Year's, Presidents' Day) are peak revenue periods. Winter also brings the highest operating costs — snow removal, heating, and potential weather-related repairs.
Summer season (June - September). Big Bear Lake transforms into a summer destination for boating, kayaking, fishing, hiking, and mountain biking. Summer occupancy has grown significantly as hosts market to families and outdoor enthusiasts. Operating costs shift to landscaping, deck maintenance, pest control, and dock or lake equipment upkeep.

Winter Access Challenges
Big Bear's mountain location creates unique access issues that affect both hosts and guests. During winter storms, CalTrans may require tire chains on Highway 18 and Highway 38. Many guests arriving from Los Angeles do not own chains or four-wheel-drive vehicles, leading to cancellations, late arrivals, and guest complaints.
Hosts who purchase loaner tire chains for guests, maintain 4WD shuttle arrangements, or provide detailed access instructions with chain rental locations are investing in guest experience and reducing cancellations. The cost of chains, access supplies, and any shuttle services are deductible business expenses. Guest-facing supplies and services that reduce friction are legitimate operating costs.
Federal Deduction Strategies for Big Bear Hosts
Schedule C filing. Most Big Bear STRs qualify for Schedule C if the average guest stay is seven days or fewer and you provide substantial services (cleaning, linens, toiletries, firewood, welcome amenities). This is standard for vacation cabin rentals. See our Schedule C vs Schedule E guide for details.
Cost segregation. Big Bear cabins with significant furnishing, hot tub installations, decks, and landscaping are strong candidates for cost segregation studies. Personal property (furniture, appliances, hot tubs) and land improvements (decks, driveways, retaining walls) can be depreciated on accelerated 5, 7, or 15-year schedules instead of 27.5 years. See our depreciation guide for details.
Mileage deductions. Big Bear hosts who drive from the LA basin or Inland Empire for turnovers, maintenance, and inspections often log significant mileage. A host making a 200-mile round trip from the Inland Empire once a week logs over 10,000 miles annually — worth over $7,250 in deductions at the 2026 rate of $0.725/mile. Track every trip with DeductFlow's mileage tracker.
Finding a Big Bear STR CPA
Big Bear hosts benefit from working with a CPA who understands both California state tax obligations and federal STR strategies. When interviewing accountants, ask about experience with Schedule C vs Schedule E for vacation rentals, California TOT compliance, cost segregation, material participation documentation, and mountain-property-specific deductions. A CPA familiar with mountain resort rental markets will know which expenses to prioritize and how to structure your filing to minimize your combined federal and California tax burden.
Regardless of which CPA you choose, come prepared. The hosts who pay the least tax are the ones with organized records — every expense categorized, every mile logged, every active hour documented. That's what DeductFlow is built for.
