The Williamson Act: A Rare Perk of Some Nevada County Land

Every so often, I come across a Nevada County property enrolled in the Williamson Act, and it can be a real gem, especially for buyers who dream of farming, raising animals, or simply keeping their land open and wild.

Williamson Act land often comes with significantly lower property taxes, and the program is part of what keeps our county so beautiful and rural. Many buyers have never heard of it, so here’s a quick guide to what it is and how it works.

What is the Williamson Act?

The Williamson Act is officially called the California Land Conservation Act of 1965. It’s a voluntary agreement between a landowner and the county. The owner promises to keep the land in agricultural, open space or compatible uses instead of developing it. In exchange, the county taxes the property based on what it can earn as farmland or open space, not on its full market value.

The result is often a much lower property tax bill. Statewide, roughly 16 million acres are enrolled, which is about half of California’s farmland.

How does it work here in Nevada County?

Every county runs its own version of the program (you can read more on Nevada County’s Williamson Act page). In Nevada County:

•       The land has to be actively used. For agricultural contracts, the county looks for at least $15,000 in capital investment in the operation (not counting your house) and at least $3,000 a year in gross income from agricultural production, in at least two of the three years before you apply.

•       Zoning matters. Contracted land is generally in the county’s agricultural or forest zones (AE, A1 or FR) and has to meet the minimum parcel size for that zone.

•       Open space and recreational contracts have no minimum parcel size.

Applications go through the Nevada County Planning Department, and you’ll find the application and guidelines on the county’s Land Use Applications and Forms page. Questions about how contracted land is valued go to the Assessor’s Office.

Good to know: the contract stays with the land

One of the most important things to understand is that a Williamson Act contract doesn’t end when the property sells. It’s recorded against the land, so if you buy a contracted parcel, you take on the contract and its restrictions.

That can be a great fit. If you’re planning a homestead, a small farm, livestock, an orchard or simply want to keep the land wild, the lower taxes are a real gift. But if you’re hoping to subdivide, build several homes or start a use that isn’t agricultural, you’ll need to plan carefully.

How long does a contract last?

Contracts run for at least 10 years and renew automatically every year. In practice, there’s always about 10 years left on the clock.

Can you get out of one?

Yes, in two ways:

1.     Nonrenewal. You (or the county) file a notice of nonrenewal, and the contract winds down over the remaining years. Your taxes step up gradually each year until they reach normal market-based levels. It’s slow, but it’s the standard way out.

2.    Cancellation. This ends the contract right away, but it’s hard to get. The county has to make specific findings and approve it, and the landowner pays a hefty fee, currently 12.5% of the property’s full market value. Cancellation is the exception, not the rule.

My advice if you’re looking at a Williamson Act property

•       Ask for the contract early. Read the actual recorded contract, not just the listing note.

•       Be honest about your plans. Does the property fit what you want to do with it for the next 10 years?

•       Talk to the county. Planning and the Assessor’s Office can explain how the contract affects that specific parcel. The county’s Williamson Act page has their contact info.

•       Check whether a nonrenewal has already been filed. That changes the tax picture and the timeline.

To me, the Williamson Act is a big part of why Nevada County still feels the way it does: open, rural and full of working land. For the right buyer, finding one of these properties is a wonderful opportunity.

If you’re eyeing a property with a Williamson Act contract, or wondering whether your own land could qualify, reach out. I’m always happy to walk the land with you and talk it through.
