Landlocked Parcels at Tax Sale: How to Check Access Before You Bid

A parcel with no legal way to reach it is the classic tax-sale trap. It looks like land on the map, it carries an assessed value, and it opens at a few thousand dollars. What it lacks is the one thing that makes land usable: a right to get to it.

This article covers why landlocked parcels end up at tax sale, the difference between legal and physical access, what California law does and does not offer an owner who is cut off, and how to check before you bid. It ends with what our own road test shows across the four counties we currently track.

Why landlocked parcels end up at tax sale

Tax sales select for parcels nobody wants to keep paying on. Access problems produce exactly that:

• Remnant strips. When a larger holding is split or a road is realigned, slivers get left behind: a strip between a highway and a fence line, or a leftover triangle from a subdivision. They are assessed, taxed, and eventually abandoned.
• Interior lots in paper subdivisions. Sierra foothill counties are full of subdivisions mapped in the 1920s–1960s where the streets were never built. Lots in the middle of the map have no physical road and often no recorded easement either.
• Old mining and homestead patents. Parcels traced to federal patents were often accessed informally across neighbouring land for decades. When ownership changes hands, the informal arrangement dies with it.
• Inheritance. An heir who never visits a rural parcel stops paying the bill. The parcel may have had access through a relative's adjoining land, which the heir does not own.

Because the minimum bid is set by unpaid taxes and not by value, a landlocked parcel opens at the same kind of figure as a usable one. Nothing in the listing flags the difference.

Legal access is not the same as physical access

Physical access means you can drive or walk onto the parcel from a road. Legal access means you have a right to do so. A parcel can have either without the other.

A parcel can front a paved county road and still have no legal access if the county road is a private road-maintenance district or the frontage is separated by a strip owned by someone else. A parcel can sit a mile from pavement and have perfect legal access through a recorded easement across three neighbours.

What you are buying at a tax sale is title, and the rights that go with it. Under Revenue and Taxation Code §3712 a tax deed conveys the parcel free of most encumbrances but expressly subject to "easements constituting servitudes upon or burdens to the property" — and, by the same logic, an easement that benefits the parcel runs with the land to you. What the deed does not do is create access that did not exist before.

Where legal access comes from

An easement of record. A recorded grant of easement, or an access easement shown on a recorded subdivision map or parcel map, is the clean answer. It names the burdened parcel, describes the route, and binds later owners.

An implied easement. California recognises easements that were never written down, but each has conditions:

• Easement by necessity requires that the landlocked parcel and the parcel it would cross were once owned by the same person, and that the landlocked parcel was cut off when they were separated. The necessity must be strict, not merely convenient. Where the common owner was the federal government — which is the case for most rural Sierra land, since it was patented out of the public domain — the California Supreme Court in Murphy v. Burch (2009) 46 Cal.4th 157 held that a claimant must also show Congress intended to reserve access and that the government could not have condemned an easement. In practice that makes the claim very hard to win for patented land.
• Prescriptive easement requires open, notorious, continuous and hostile use for five years (Civil Code §1007, Code of Civil Procedure §321). A prior owner's use may count, but you will have to prove it, and a prescriptive easement cannot be exclusive.
• Easement implied from prior use requires a visible, pre-existing use at the time the parcels were separated.

Each of these is a lawsuit, not a document. You establish it by suing the neighbour for quiet title and winning.

What California does not have is a general private-condemnation right for a driveway. Civil Code §1001 lets a property owner use eminent domain to acquire an easement for utility service — water, gas, electric, drainage, sewer or telephone — and only on a showing of "great necessity." Civil Code §1002 covers temporary entry onto a neighbour's land to repair a building. Neither gives a landlocked owner the power to condemn a road.

How to check before you bid

In order of cost:

1. Look at the assessor's parcel map. Every county publishes them by book and page. Easements are usually drawn as dashed lines with a recording reference. Absence of a dashed line is not proof of no easement, but presence of one is a lead.

2. Overlay road layers. County GIS viewers carry a roads layer; the U.S. Census TIGER/Line road file is a free statewide fallback; the Forest Service's Motor Vehicle Use Maps show which forest roads are open to the public. If no road of any kind touches the parcel polygon, that is the first hard signal.

3. Search the recorder's index. Search the grantor-grantee index for the parcel's current and prior owners and for the neighbouring parcels. You are looking for "easement," "right of way" or "road agreement" in the document type. Many counties have the index online; the documents themselves may need to be ordered.

4. Order a preliminary title report. A title company will search the chain of title for recorded easements benefiting and burdening the parcel. This is the definitive check, and it costs money, so do it on the parcels still standing in the final week rather than on the whole list — see why parcels disappear before sale day.

5. Look at the ground. Aerials show whether a track actually exists. A track without a recorded easement is physical access without legal access; a recorded easement across a ravine is the reverse.

What our road test shows across four counties

For every live parcel with a county polygon we test whether any Census TIGER/Line road segment comes within 15 metres of the parcel boundary, and if so whether it is a public road, a private road or an unpaved vehicular trail. As of September 22, 2026, across the 158 non-timeshare parcels on the current lists for Placer, Nevada, El Dorado and Calaveras:

County	Live parcels	No mapped road touches the parcel	Only a private road or 4WD trail	Public road touches
Calaveras	44	7	0	37
El Dorado	38	7	0	31
Nevada	40	8	1	31
Placer	36	6	2	28
Total	158	28 (17.7%)	3 (1.9%)	127

Twenty-eight of 158 parcels — a little under one in five — touch no mapped road at all. Three more touch only a private road or an unpaved trail, where legal access then depends on a recorded easement or road-maintenance agreement.

Now the caveat, which matters more than the table. TIGER misses roads. It is good on public roads and poor on private and forest roads, ranch tracks, and roads inside gated subdivisions. A parcel in the "no mapped road" column may well have a perfectly good gravel road to its gate that the Census never mapped. Conversely, a parcel that touches a public road on the map may be separated from it by a strip of someone else's land or a cut bank.

So the 28 is a list of questions, not a verdict. It tells you which parcels need the recorder's index and a title report before you bid, and which ones you can probably afford to check more cheaply. It does not tell you a parcel is landlocked, and it certainly does not tell you one is not.

What "no access" does to the numbers

We cannot yet measure sell-through by access status, because the road test only runs on live parcels, and the results we hold for past sales are not tagged for it. What we can say is that unsold parcels are heavily over-represented among those with no situs address and no assessor match — in Placer, sold parcels matched the county's GIS 63.6% of the time and unsold parcels 21.5%, of 404 full-roster results 2013–2025. Parcels with no address are disproportionately the remnant strips and interior lots that also lack access. Why California tax sale parcels go unsold has the full breakdown.

If you buy one anyway

Some buyers deliberately bid on landlocked parcels: to sell to the neighbour who already uses them, to assemble with an adjoining lot, or because the parcel has a recorded easement that the price does not reflect. That can work, with three cautions:

• Price it as a parcel you may never be able to reach. Assessed value is not a floor for landlocked land.
• Budget for a quiet-title action if you intend to establish an implied easement. See quiet title after a California tax deed sale for the process.
• Talk to the neighbour before the sale, not after. If the only realistic buyer is the adjoining owner, find out whether they want it — and whether they are bidding.
