Lake and ski STR cabins serving LA and Orange County, where high-bracket investors capture the full federal Year-1 deduction (federal 37% + NIIT 3.8%) on every reclassified dollar. California does not conform to federal bonus depreciation, so the California 13.3% share follows over the MACRS recovery period rather than Year 1.

The Big Bear Market
Big Bear Lake is one of LA’s three primary weekend-escape STR markets (along with Joshua Tree and Lake Arrowhead). The market splits between ski-season cabins near Snow Summit / Bear Mountain, summer-season lakefront homes, and year-round cabins in Sugarloaf and Moonridge. Purchase prices generally run $400K–$900K with renovation budgets that vary widely: newer Moonridge builds are turnkey at higher prices, while older Sugarloaf cabins often need $50K–$150K of guest-experience upgrades to compete in the market. Federal acceleration is the biggest Year-1 driver here: every reclassified dollar saves roughly 41¢ in federal-plus-NIIT tax for high-bracket investors. California does not conform to federal bonus depreciation, so the California share follows over the MACRS recovery period rather than Year 1.
Why Cost Segregation Hits Different in Big Bear
Two property-type features stack on the California tax wedge. First, Big Bear cabins generally carry hot tubs, theater rooms, ski-storage build-outs, themed bunk rooms, and outdoor decks with mountain views, all 5-year or 7-year FF&E. Second, the steep mountain lots demand significant site work: retaining walls, exterior staircases, gravel driveways with snow-grade drainage, fencing, and outdoor structures, all of which reclassify to 15-year MACRS rather than the default 27.5-year residential schedule. Combine those two with the federal Year-1 deduction and you get a strong reclassification on a high-FF&E, high-site-work property type. California’s 13.3% rate applies to the same depreciation but over the MACRS recovery period, not as a Year-1 add.
Worked Example: Big Bear
A 3BR 2BA cabin purchased for $685,000 in Moonridge with $40K in renovation (new hot tub, ski-storage build-out, deck refresh). After $150K in land, the $535K adjusted basis includes $55K in 5-year assets (hot tub, appliances, theater equipment, decorative lighting, smart-home equipment, ski-storage racks), $22K in 7-year assets (custom bunk-room furnishings, mountain-themed decor), and $65K in 15-year property (mountain-grade deck, retaining walls, gravel drive with snow drainage, fencing, exterior staircase). That’s $142K reclassified into accelerated depreciation in Year 1.
Who Is Doing This in Big Bear
Big Bear investors are overwhelmingly high-income LA and OC W-2 earners (entertainment-industry professionals, tech, doctors, and business owners) operating at the 37% federal bracket plus 3.8% NIIT, with the 13.3% California bracket on top. The ~40.8% federal-plus-NIIT rate drives the Year-1 math; the California share follows over the MACRS recovery period because California does not conform to federal bonus depreciation. The 7-day STR material participation rule under §469 lets these investors use accelerated depreciation against active income when they qualify, which is the actual reason most LA-based investors choose Big Bear over a long-term-rental property in the city.
CA Tax Considerations
- California’s top marginal rate of 13.3% applies to the same depreciation but over the MACRS recovery period, not as a Year-1 add. California does not conform to federal §168(k) bonus depreciation, so the California share follows over the MACRS recovery period rather than Year 1 (California bonus depreciation: non-conformity rules).
- A $142K reclassification generates roughly $58,000 in Year-1 federal savings (federal 37% + NIIT 3.8% = ~40.8%). The California portion is not accelerated in Year 1; it recovers over the standard 5/7/15-year MACRS schedules.

What People Worry About (and What Actually Happens)
“Will this trigger an IRS audit?” No. Cost segregation is explicitly supported by IRS guidelines (Rev. Proc. 87-56) and the IRS Audit Techniques Guide for Cost Segregation. Our reports run 40+ pages with component-level documentation. audit risk and cost segregation →
“Does California conform to federal bonus depreciation?” No. California does not conform to federal §168(k) bonus depreciation (R&TC §17024.5) and never has, including after SB 711. You still claim the full federal Year-1 deduction; the California portion is not accelerated and instead recovers over the standard 5/7/15-year MACRS schedules, so it is deferred, not lost. Confirm the federal vs California schedules with your CPA (FTB Form 3885A).
“My CPA hasn’t mentioned this.” Most CPAs know about cost segregation but don’t proactively recommend it because they don’t do the engineering analysis in-house. We provide the engineering piece. Your CPA files the results.
Frequently Asked Questions
How much does a cost segregation study cost in Big Bear Lake? For a representative $685,000 Big Bear Lake investment property, a Cost Seg Smart study runs $895. Full pricing: $495 (under $300K), $895 ($300K–$700K), $995 ($700K–$1M), $1,295 ($1M–$1.5M), $1,595 ($1.5M–$2M), $1,995 ($2M–$3M), $2,495 ($3M–$4M), $3,995 ($4M–$6M), $5,995 ($6M–$8M), $7,995 ($8M–$10M). Commercial and 5+ unit multifamily studies start at $1,995; 2–4 unit multifamily from $795. All studies delivered in under one hour with the CPA-Ready Guarantee: full refund if your CPA can’t use the report.
Do I need to materially participate to use the deduction? For the STR active-income path under §469, yes: 100+ hours per year and more than anyone else (including property management). If you don’t materially participate, the depreciation only offsets passive income, which is still valuable but doesn’t open up the W-2 offset.
What if I bought before 2025 when bonus depreciation was lower? The bonus depreciation rate that applies is the rate in effect at the placed-in-service date: 100% (2025+), 60% (2024), 80% (2023), and so on. We model your specific vintage in the report.
Are there other LA-area mountain STR markets you cover? Yes. See Joshua Tree, CA for desert STR and Palm Springs, CA for desert resort STR. All three share the CA 13.3% top-rate stack.

CPA use note: These figures estimate the size of the depreciation deduction. Whether the loss is usable in the current year depends on passive-activity rules, STR material participation, REPS status, entity structure, depreciable basis, and state conformity. Your CPA decides how and when it is applied. Specialty and site components (equipment, casework, docks, pools, arenas, tenant improvements, and similar) are only classified when you own them and they are included in the depreciable basis being studied.
How should Big Bear Lake, CA investors choose a cost segregation provider?
For a Big Bear Lake, CA investor buying a property in the $685,000 range, the choice of provider is a major controllable variable in the return. The IRS Audit Techniques Guide sets the quality characteristics an engineering-based study should meet — industry-standard construction cost data, MACRS classification, and component-level documentation — but it does not make every provider's work identical; rigor, cost, and turnaround still vary.
Traditional engineering studies often run several thousand dollars and can take several weeks, because they include on-site inspections, sales discovery calls, and scheduling overhead. The IRS Cost Segregation Audit Techniques Guide does not prescribe an on-site inspection as a standalone requirement; it sets out the quality characteristics of an engineering-based study — component-level classification, a documented and supportable cost derivation, and a clear audit trail — and describes how a physical inspection can contribute to meeting them.
Modern automated providers (such as Cost Seg Smart) deliver an engineering-based, IRS ATG-aligned study using property records, documents, photos, and recognized construction-cost data, typically from $495 and often the same day. For a Big Bear Lake, CA investor at a high combined bracket, that cost and speed difference is meaningful. The CPA-Ready Guarantee (full refund if the report can't be used by your CPA) plus the 60-day money-back policy makes the decision essentially risk-free on the report itself.
The automated path is best-fit for owners who can provide closing documents and property photos online (no in-person visit required) and want the report in time to file the current year's return rather than the next one.
All Cost Seg Smart studies include the CPA-Ready Guarantee (full refund if your CPA can't use the report) plus a 60-day money-back policy. Straightforward residential studies are often delivered the same day and completed remotely; larger or more complex commercial studies take longer and may include an on-site observation.
