Placer County Land for Sale

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

Land for sale in Placer County runs from lots in the valley cities to foothill acreage and forested parcels in the Sierra and the Lake Tahoe Basin. Whether you can build depends on the zoning district, a septic soils report if there’s no sewer, and, at Tahoe, a second regional agency’s rules. Before you write an offer, ask Environmental Health whether the parcel already has a soils testing report, and find out who sets the zoning.

At a glance

Where to look in Placer County

Placer’s land search breaks into three broad settings, each with a different set of questions. Our valley, foothill and mountain comparison covers the trade-offs in more detail.

• Valley and the cities. Lots in Roseville real estate and the other incorporated cities follow city zoning and usually connect to city services. Placer County notes that Auburn, Rocklin, Roseville, Lincoln and Loomis have their own building departments (Septic Systems). Farther west, unincorporated land is more often in agricultural zones such as AE and F.
• Foothills. Unincorporated foothill land is often zoned RA or RF, served by wells or a water purveyor and septic, and reached by private roads. Confirm water service early; our rural house utilities records guide explains what to request. If you’re thinking about planting, see Placer County vineyards.
• Sierra and Lake Tahoe. Forested parcels may be in FOR, TPZ or RF zones. Inside the Lake Tahoe Basin, the county’s Tahoe Basin Area Plan and TRPA’s rules apply on top of county zoning. Snow, access and fire safety shape what you can build; see home insurance and site access in Placer County.

For the county’s communities and housing types, see the Placer County where-to-live guide.

What to check before you buy

Who has jurisdiction, and what’s the zoning

First confirm whether the parcel is inside a city or in the unincorporated county. For unincorporated land, Placer’s zoning ordinance sets the districts: agricultural and resource zones (AE, F, FOR, O, TPZ, W), residential zones (RA, RF, RS, RM) and specific plan areas. A Building Site (-B) combining district (Section 17.52.040) can set a different minimum building site for an area. The code itself is hosted on eCode360, and Placer’s Zoning Research and GIS pages help you look up a parcel (Placer County Zoning Ordinance). Read the full designation, including any -B suffix, before assuming you can split a parcel or add a second home. Our jurisdiction and permit research guide walks through the lookup.

Septic: look for an existing soils report

Placer Environmental Health says to check whether a parcel already has a soils testing report before you draw plans. If it doesn’t, soils testing is required. It’s done by a sewage disposal consultant together with an Environmental Health representative, and the results set the system’s type and location. The design also has to fit a designated leach field repair area, setbacks and both your well and neighboring wells. Permit applications need the septic construction permit and site evaluation forms with site plans and assessor’s parcel pages (Placer County Septic Systems).

For a buyer, an existing soils report is a valuable document. Ask the seller for it, and if none exists, make soils testing a contingency.

Wells and water

Environmental Health handles well drilling permits; the application is on its Permits & Forms page. Some foothill parcels can connect to a water purveyor instead, so ask the seller and check with the local provider. If you’ll rely on a well, ask for the well log and recent yield and water quality results, and treat a new well’s yield as unknown until it’s drilled.

Williamson Act contracts

Placer County’s basic minimums for a Williamson Act contract are 20 acres and $4,500 in gross agricultural income a year. The initial term is ten years, renewing automatically each year. The contract binds new owners, limits use to agriculture and compatible uses, and limits residences to people who work full time on the preserve. Nonrenewal ends the contract nine calendar years after the notice; cancellation requires Board findings and a fee of 12.5% of full market value (Placer County). Statewide, the Department of Conservation confirms contracts are binding on later purchasers (DOC Williamson Act FAQ). If you plan to live on contracted land without farming it full time, talk to the Planning Department, (530) 886-3000, first. See also our Williamson Act guide.

Fire Safe roads, driveways and water

The State Minimum Fire Safe Regulations (14 CCR 1270 et seq.) apply to new residential, commercial and industrial buildings in the State Responsibility Area approved after January 1, 1991, and in Very High Fire Hazard Severity Zones approved after July 1, 2021. They also cover new parcels, use permits and new roads, and building permits on older parcels where access conditions were never set. Roads used only for agriculture or timber management are excluded from the road standards (14 CCR 1270.03). In the foothills and mountains, plan for this before you budget a driveway.

Building in the Lake Tahoe Basin

Land in Placer’s share of the Tahoe Basin has an extra layer of rules. TRPA was created by a 1969 compact between California and Nevada and has land use authority across the Basin, including enforcing its Code of Ordinances. Its site lists development rights and land capability and coverage as separate topics, so start there when you evaluate a lot (TRPA). Placer applies its own Tahoe Basin Area Plan and implementing regulations, and its Tahoe office is in Tahoe City, 530-581-6200 (Placer County Zoning Ordinance; Tahoe Basin Area Plan regulations). Before buying a Tahoe lot, ask TRPA and the county what the parcel needs to be built on.

Private roads and snow

Many foothill and mountain parcels share a private road. Under Civil Code 845, easement owners must keep a private right-of-way in repair and, absent a written agreement, share costs in proportion to use. The statute also treats a cost-sharing agreement as covering snow removal in some cases: when it isn’t excluded, is needed for access and is approved in advance by the owners (text via california.public.law). At elevation, ask who plows the road and how it’s paid for. See our guide to private road maintenance agreements in California.

How we approach a land purchase

1. Confirm the jurisdiction (city, county, and at Tahoe, TRPA) and the full zoning designation.
2. Ask Environmental Health and the seller for any soils report, well log or water service letter.
3. Write septic, water and access review into your contingencies.
4. Talk with county planning before you remove contingencies if you plan to build, split or farm under contract.

Our guide to buying land in California covers each step, and our buyer services page explains how we represent buyers.

Questions people ask

How do I find a Placer County parcel’s zoning?

Use the county’s Zoning Research and GIS/Maps pages, then read the district in the zoning ordinance on eCode360. Inside a city, the city sets the zoning.

What does a "-B" in Placer zoning mean?

It’s the Building Site combining district (Section 17.52.040), which can set a different minimum building site than the base zone. Read the section for the number that applies.

Does vacant land need a perc or soils test before I build?

If the parcel doesn’t already have a soils testing report on file with Environmental Health, testing is required before a septic system is designed.

Can I live on Williamson Act land in Placer County?

Placer limits residences on contracted land to people who work full time on the agricultural preserve. Confirm with the Planning Department for a specific parcel.

How long does Williamson Act nonrenewal take?

In Placer, the contract ends nine calendar years after a Notice of Non-Renewal is served, counted from the January 1 renewal date.

What extra rules apply to land at Lake Tahoe?

Development in the Basin falls under TRPA as well as the county’s Tahoe Basin Area Plan. Check development rights and land coverage with TRPA before you buy.

Do Fire Safe regulations apply to my parcel?

They apply to new construction in the State Responsibility Area, and in Very High Fire Hazard Severity Zones for approvals after July 1, 2021.

Who pays for snow removal on a private road?

Civil Code 845 treats a shared road agreement as including snow removal when it isn’t excluded, is needed for access and the owners approve it in advance. Read the road agreement.
