California Real Estate by County & City

Oakland and Berkeley layer some of the steepest city transfer taxes in the state on top of the county base, and the Hayward Fault runs straight through the county's densest cities.

Alpine County has no incorporated cities and almost no conventional residential market — here's what buying near Kirkwood or Bear Valley actually involves.

Amador County's Gold Rush mining legacy comes with a real disclosure statute, and the county has direct, confirmed wildfire history from the 2015 Butte Fire.

The Camp Fire and the Oroville Dam spillway crisis are the two defining hazard events for Butte County buyers — here's what each means today.

Between a confirmed mining-operation disclosure statute and the 2015 Butte Fire footprint, Calaveras County has two real hazard categories worth checking before you buy.

Colusa County's rice economy depends on reliable irrigation water — and that reliability has genuinely broken down in recent drought years.

Richmond has a steeply tiered transfer tax, East County new construction often carries Mello-Roos, and the Hayward and Concord faults run through much of the county's populated core.

Crescent City has been hit by more tsunamis than anywhere else on the U.S. West Coast — a fact any buyer near its downtown or harbor should know before writing an offer.

From Cameron Park and El Dorado Hills to South Lake Tahoe, the county spans two very different buying environments — and the Tahoe Basin has its own permitting agency on top of the county.

No transfer-tax surprise here — the real distinguishing factors for a Fresno County buyer are agricultural land-use restrictions, air quality, and river flood risk.

Glenn County split off from Colusa in 1891 and shares the same defining risk for agricultural land: documented water-allocation volatility, not just generic drought.

Humboldt County's cannabis cultivation history can attach code-enforcement liability to a property itself — a genuine due-diligence item most California counties don't have.

The Salton Sea is a genuinely severe, worsening environmental crisis — and the county is simultaneously home to a fast-moving lithium industry and one of the state's most active fault zones.

The Owens Valley water dispute is not settled history, and the valley floor sits on one of California's most active fault systems — both shape what buying here actually involves.

California's top oil-producing county has real estate quirks most other counties don't — from well proximity to Williamson Act farmland.

Naval Air Station Lemoore's low-altitude jet noise and Corcoran's severe, ongoing land subsidence are two real, mapped factors most other counties don't have.

Wildfire history and insurance availability are the single most important facts for any buyer evaluating property in Lake County.

Lassen Peak is one of the few volcanoes in the contiguous U.S. that has erupted in the last century — and fire has run directly at Susanville twice in the last several years.

Local transfer tax rules, closing-cost customs, and disclosure nuances for buying a home in LA County — not the same everywhere in the county.

Madera County's foothill growth boom near Millerton Lake comes with real Mello-Roos and expanding fire-map exposure — here's what buyers should check.

San Rafael's city transfer tax, West Marin's strict growth controls, and the San Andreas Fault running straight through Olema Valley are the things most likely to surprise a Marin County buyer.

Mariposa's market is shaped heavily by Yosemite National Park tourism and vacation-rental demand — layered on top of real, recurring wildfire exposure and Gold Country mining hazards.

Coastal-zone permitting, an actively rupturing fault, agricultural zoning, and cannabis-related property history all overlap in a Mendocino County purchase.

UC Merced's opening in 2005 reshaped housing demand in the city of Merced — and the county's Williamson Act program, Mello-Roos financing, and flood-prone valley floor each have specific wrinkles buyers should know about.

Extreme remoteness, rather than any specific hazard category, is the defining fact for a buyer in Modoc County.

An actively monitored volcanic system beneath Mammoth Lakes and one of California's most significant historic water-rights battles define Mono County for a buyer.

The Monterey Peninsula's decades-long water moratorium directly affects what you can build — verify it before you assume anything.

The nation's first Agricultural Preserve, recurring wildfire, and a real legal fight over vineyard well water are the forces shaping any Napa County purchase.

Gold Rush-era hydraulic mining left Nevada County with real, documented mine-shaft and mercury-contamination risks, and Sierra foothill terrain adds real wildfire exposure on top.

No mansion tax here, but Mello-Roos and master-HOA layering catch OC buyers off guard more than in most CA counties.

Placer County is really two markets under one government — Sacramento-suburb growth cities and TRPA-regulated North Lake Tahoe — and the Town of Truckee itself isn't even in the county.

The Dixie Fire — nearly a million acres, downtown Greenville destroyed — is the defining fact for any buyer evaluating property in Plumas County today, and the county's 2025 fire-hazard maps are worth checking directly.

Mello-Roos on newer master-planned homes and an unusually heavy reliance on FHA/VA financing are the two things most likely to catch an unrepresented Riverside County buyer off guard.

The City of Sacramento charges its own transfer tax instead of the county rate, and parts of Natomas carry flood-insurance requirements that change parcel by parcel as levee work progresses.

The Calaveras Fault's continuous, decades-documented creep through Hollister is the single most distinctive fact for a San Benito buyer — and newer Hollister subdivisions carry real, active Mello-Roos districts too.

California's largest county by land area spans three very different buyer questions — well/septic in the High Desert, wildfire insurance in the mountains, and CFDs in the newer Inland Empire suburbs.

San Diego doesn't have one dominant tax quirk — its distinguishing factors are almost all about where in the county a property sits: coastal permitting, military base proximity, backcountry fire risk, and Mello-Roos.

San Francisco is city and county combined — its transfer tax is the steepest in the state, and TICs exist because condo conversion is capped by lottery.

Delta geography and Bay Area commuter growth drive the real quirks here — not any single tax surcharge.

Water availability — not price — has been SLO County's defining land-use constraint for decades, and the county sits within reach of three separately zoned earthquake faults.

The City of San Mateo's own conveyance tax is a genuine outlier — and East Palo Alto and Foster City each carry a real, distinct buyer quirk of their own.

The 2018 Montecito debris flow still shapes hillside risk mapping, and Santa Barbara city rent rules are actively changing.

San Jose layers its own transfer tax plus a steep Measure E surcharge on high-value sales, and the county has an unusually active ADU permitting environment.

The City of Santa Cruz added a large graduated transfer-tax surcharge on high-value sales in 2026 — and the coastline, mountains, and downtown core each carry their own real risks.

The Carr Fire didn't just burn the hills — it reached inside Redding's city limits, making wildfire a mainstream consideration in Shasta County, not an edge case.

With no large incorporated city, Sierra County real estate runs on well, septic, and privately-maintained roads far more than any conventional market.

Mount Shasta volcanic hazard, wildfire exposure, and active water-rights curtailment are the three issues most likely to surprise a buyer in Siskiyou County.

Vallejo's transfer tax is quadruple the county rate, and Rio Vista's Delta flood exposure is real — two things that catch buyers off guard.

Recurring, severe wildfire history and a notably high transfer tax in the county's two largest cities set Sonoma apart.

In Modesto Irrigation District territory your electric utility may not be PG&E — one of several county-specific quirks worth confirming.

Sutter County has a real, twice-documented history of levee failure — and a named benefit-assessment district has since collected roughly $1 billion specifically because of it.

The fourth-largest wildfire in California history burned directly into Tehama County in 2024 — a fact every buyer here should know.

No incorporated cities, mostly national forest, and real, worsening wildfire exposure — Trinity County buyers face a different due-diligence checklist than almost anywhere else in CA.

The historic Tulare Lake basin re-flooded in 2023 after decades dry — a real, reactivatable risk, not purely historical.

Site of the 2013 Rim Fire, a Gold Rush mining legacy with a real disclosure statute behind it, and a Yosemite-gateway short-term rental market with its own ordinance.

From Pacific coastline to fire-prone hillside towns, Ventura County's rules shift sharply depending on exactly where a property sits.

The Yolo Bypass floods by design in wet years — a working flood-control feature, not a hazard footnote — while the county's western hills carry real, separate wildfire risk.

Two real, fatal levee failures make flood history a specific due-diligence item for the Linda/Olivehurst/Arboga area, and Plumas Lake carries real, named Mello-Roos special taxes.
