## State tax context, California
California decouples from federal §168(k). The 100% federal bonus depreciation restored by OBBBA in 2025 produces real federal-tax savings, but California requires the deduction to be added back on Schedule CA (540) and the basis depreciated on the regular MACRS schedule for state purposes. For Los Angeles owners in California's top 13.3% bracket, the headline federal-savings number overstates total tax savings — the state-side California acceleration that would have occurred under federal conformity is recovered slowly over the regular 27.5- or 39-year schedule instead.

**Decoupling note:** California's decoupling is permanent and structural. Federal §168(k) at 100% reduces federal liability; California treats the property under the regular MACRS schedule. For LA cost-seg buyers in the top California bracket, model federal-only savings as your Year-1 win.


## Neighborhood profiles
- **Silver Lake / Echo Park (Eastside)**, typical value $1,325,000, land allocation ~38%. 1920s–1940s SFR and bungalow stock heavily renovated. High land allocation (eastside land scarcity premium). Fix-and-flip dominant; some STR-loophole-eligible properties where owner-occupies primary residence.
- **Highland Park / Eagle Rock**, typical value $1,050,000, land allocation ~34%. Northeast LA — 1920s craftsman bungalow stock with heavy renovation cost-segregation potential. Slightly lower land allocation than Silver Lake. ADU rush since 2017 ADU law. Mix of fix-and-flip and small MF.
- **Mid-City / Mid-Wilshire**, typical value $1,450,000, land allocation ~32%. Pre-war duplex and small MF dominant. The cost-seg study really works here on 2-4 unit acquisitions — multiple units mean multiple FF&E packages and shared-system depreciation. Active small-MF investor market.
- **Sherman Oaks / Valley Glen (San Fernando Valley)**, typical value $1,850,000, land allocation ~30%. 1950s–1970s SFR with substantial post-2010 renovation activity. ADU developments common. Larger lot sizes mean ADU yields are meaningful additions to depreciable basis.
- **South LA / Leimert Park**, typical value $685,000, land allocation ~24%. Lower entry pricing, 1920s bungalow and small MF stock. Strong fix-and-flip activity. Lower land allocation than Westside / Eastside. Cost-seg works particularly well on 2-4 unit acquisitions in this price band.


## Worked examples (engine outputs)

- **Highland Park Craftsman + ADU** (Highland Park / Eagle Rock): $1,050,000 sfr, basis $601,650, accelerated $96,505 (16.0% reclass), Y1 federal savings @ 37%: $35,707
- **Mid-City Duplex Investor** (Mid-City / Mid-Wilshire): $1,485,000 duplex, basis $825,808, accelerated $146,530 (17.7% reclass), Y1 federal savings @ 37%: $54,216
- **Sherman Oaks SFR + Detached ADU** (Sherman Oaks / Valley Glen (San Fernando Valley)): $1,850,000 sfr, basis $1,133,865, accelerated $184,431 (16.3% reclass), Y1 federal savings @ 37%: $68,239

## Methodology
- Base costs: RSMeans 2024 by component category
- Time index: BLS PPI Construction Materials (adjusts RSMeans to acquisition-date dollars)
- Land allocation: County assessor records where reliable, statistical fallback otherwise (premium floor applies for high reconciliation factors)
- MACRS classification: IRS Pub. 946 + Rev. Proc. 87-56
- Bonus depreciation: 100% (OBBBA permanently restored, 2025+)
- All numbers reproducible from `cities/losangeles.json` fixtures via `scripts/run_city_stats.py`

## Regulatory context
City of Los Angeles Home-Sharing Ordinance: Short-term rentals (stays under 30 days) are generally restricted to a host's primary residence, with annual cap on hosted-stay nights and registration/permit requirements. Non-primary-residence STR operation is largely prohibited in LA city limits. This is the single most important regulatory fact for cost-seg planning in LA — absentee STR strategies do not translate from Joshua Tree, Palm Springs, Tahoe, or other §469-loophole markets. Adjacent jurisdictions with different regimes: West Hollywood (permits available), Burbank (some areas permit), Pasadena (limited permits). Verify jurisdictional boundaries carefully — addresses on the same block can fall under different regulatory regimes. For non-STR investor strategies (fix-and-flip, small MF, ADU), there is no STR ordinance to manage; standard rental property §469 passive-loss rules apply, and real-estate-professional status is the typical path to active treatment for high-volume LA flippers.
