Easement

An easement is a nonpossessory interest in another person's land: the right to use it for a defined purpose, without the right to occupy or exclude. Cornell's Legal Information Institute states it as "the grant of a nonpossessory property interest that provides the easement holder permission to use another person's land." California's Civil Code takes the older vocabulary and calls the same thing a servitude, listing at section 801 the "land burdens, or servitudes upon land" that "may be attached to other land as incidents or appurtenances, and are then called easements," among them the right-of-way, the right of taking water, and the right of receiving air, light or heat over land. The words differ; the idea does not. A servitude is the burden as the servient land experiences it, and an easement is the same burden named from the holder's side.

The feature that makes an easement worth understanding is that it runs with the land. An owner who grants a neighbor a right of way has not made a personal promise that expires when either of them sells. The right attaches to the parcels, so the neighbor's buyer keeps it and the grantor's buyer takes the land subject to it. That is why an easement is an encumbrance in the strict sense: a claim against the property held by someone who is not the owner.

Appurtenant or in gross. An appurtenant easement involves two parcels. The parcel that bears the burden is the servient tenement and the parcel that enjoys the benefit is the dominant tenement, and the benefit transfers automatically with the dominant parcel. An easement in gross has no dominant parcel: it benefits a person or an entity directly. California recognizes the category expressly at Civil Code section 802, which lists burdens that "may be granted and held, though not attached to land." A utility company's right to run a line across a hundred back yards is the everyday example, and it is the reason a homeowner can be bound by a right that belongs to a corporation rather than to a neighbor.

Affirmative or negative. An affirmative easement lets the holder do something on the burdened land, such as drive across it or lay a pipe under it. A negative easement prevents the owner from doing something on their own land that would otherwise be lawful, such as building a structure that blocks light or a view. The distinction matters because a negative easement can be invisible on the ground: nothing has been built, so nothing looks unusual.

How one is created, including without paperwork. The Legal Information Institute lists four routes: express grant, implication, necessity, and adverse possession. Only the first involves a document anyone signed with the easement in mind. An easement by necessity typically arises when a parcel is divided in a way that would otherwise leave one piece landlocked. An easement by implication arises from an obvious, continuous use that existed before the split. An easement acquired by long use arises because the use went on openly and without permission for the period the state's law sets. The consequence is that the records can be complete and still not be exhaustive, which is the gap a title search cannot close by itself.

How one ends. Easements are not permanent by nature. California's Civil Code section 811 states four ways a servitude is extinguished: the right and the servient land come into the same hands; the servient land is destroyed; the holder does something incompatible with the easement's nature or exercise, or assents to it; or, where the easement was acquired by enjoyment, the holder stops using it for the period the state sets for acquiring by enjoyment. The scope of what survives is fixed at section 806 by "the terms of the grant, or the nature of the enjoyment by which it was acquired," so an easement for farm access does not silently widen into a right to run a commercial driveway.

An easement is private; zoning is public. They both limit what an owner can do, and they are not the same mechanism. A zoning rule is a local ordinance that applies to a district and can be amended by the body that passed it. An easement is a property right held by an identifiable person or company, and only that holder can release it. Recorded restrictions imposed by a subdivision or enforced by an association are a third thing again.

An easement affects an owner in three places: what can be built, what can be sold, and what the title report says. Working through them in order:

1. Find it. A title search returns recorded easements. A survey shows where they physically sit, which is the part a document alone will not tell you. The two answer different questions and a buyer usually needs both.

2. Read its terms. The grant fixes the width, the location, the purpose and often the maintenance obligation. An easement described only as "access" is worth less certainty than one described as a twenty-foot strip along a named boundary.

3. Subtract it from what you can use. The land under an easement is still yours and is still taxed to you, but the easement's purpose usually rules out building over it.

A hypothetical example. A lot measures 10,000 square feet. A recorded utility easement runs 15 feet wide for the full 100-foot depth of one side boundary, which is 15 × 100 = 1,500 square feet. The buildable area is therefore 10,000 − 1,500 = 8,500 square feet, and the owner still pays property tax on all 10,000. If the local setback rules would already have kept a structure off part of that strip, the easement costs nothing extra; if they would not, it is the constraint that decides where the house sits. All figures are hypothetical.

Easements are not good or bad in themselves. Whether one helps or hurts depends entirely on which side of it you are standing.

What an easement does for its holder

• Gives a legally enforceable right that does not depend on the current owner's goodwill or survive only as long as they own the land.
• Passes automatically with the benefited parcel when it is appurtenant, so a buyer of a landlocked lot inherits its access.
• Can solve a physical problem, such as access, drainage or a utility connection, that no amount of negotiation with a future owner would reliably solve.

What an easement costs the burdened owner

• Reduces what can be built, and the reduction lands on a specific strip rather than on the parcel generally.
• Cannot be revoked by the owner alone. Releasing an easement takes the holder's agreement, and a holder who is a utility or a neighbor with genuine need has no reason to give it.
• May be enforceable even though it was never signed, because implication, necessity and long use are recognized routes to creating one.
• Can be missed. An easement created by long use and never recorded leaves nothing for a records search to find, which is one of the gaps title insurance exists to cover.
