Buying a Home in Yolo County, CA: Transfer Tax & Yolo Bypass Flood Guide
The Yolo Bypass floods by design in wet years — a working flood-control feature, not a hazard footnote, for buyers near its margins.
Yolo County, home to UC Davis and the cities of Davis, Woodland, and West Sacramento, sits directly across the Sacramento River from the state capital. Its most distinctive land-use feature is the Yolo Bypass — a massive, deliberately engineered floodway that protects Sacramento and Delta cities by design, meaning a real, mapped flood-control function runs through the county's landscape.
What’s the transfer tax in Yolo County?
Yolo County's documentary transfer tax follows the standard statewide base of $1.10 per $1,000 of consideration.
Available sourcing did not surface a confirmed local city add-on in Davis, Woodland, or West Sacramento — verify directly with the county for a specific transaction.
What is the Yolo Bypass and does it affect property flood risk?
The Yolo Bypass is a roughly 59,000-acre engineered floodway, part of the Sacramento River Flood Control Project, designed to divert floodwater away from Sacramento and Delta cities during high-water events.
It floods by design in wet years — this is intentional flood-control engineering, not a failure of the system. Property near the bypass margins should be checked against current FEMA flood zone maps, since the bypass's operational flooding is a known, mapped, and expected event rather than a rare hazard.
Which jurisdiction controls land-use near a Yolo County city edge?
It may not default to the county — Yolo County maintains distinct land-use and growth-management agreements with each of its four incorporated cities (Davis, Woodland, West Sacramento, Winters), and notably only the Davis-Yolo agreement gives the City of Davis land-use control over certain adjacent unincorporated areas.
If you're buying near a city's edge, confirm which jurisdiction actually controls land-use decisions for that specific parcel. Separately, Davis and Woodland jointly operate the Woodland-Davis Clean Water Agency, a shared water-supply infrastructure project drawing from the Sacramento River that serves both cities and UC Davis.
Disclosure landscape
- Check current FEMA flood zone maps for any property near the Yolo Bypass margins — its flooding is expected, engineered flood-control behavior, not a rare event.
- Confirm which jurisdiction (city or county) controls land-use decisions for parcels near an incorporated city's edge, since agreements vary by city.
Frequently asked
Does the Yolo Bypass flooding mean a property is unsafe to buy?
Not necessarily — the bypass is designed to flood in wet years as intentional flood-control engineering. Check current FEMA flood zone maps for the specific parcel near the bypass margins rather than assuming risk from the bypass's existence alone.
Is there a city transfer tax add-on in Davis, Woodland, or West Sacramento?
No confirmed local add-on was found in available sourcing — the standard statewide base rate of $1.10 per $1,000 applies, but verify directly with the county for a specific transaction.
Does the City of Davis control land use outside its city limits?
In some adjacent unincorporated areas, yes — the Davis-Yolo land-use agreement is the one agreement among Yolo County's four cities that gives the city control over certain adjacent unincorporated parcels. Confirm which jurisdiction controls a specific edge-of-city parcel before assuming county rules apply.
