Easements can be either positive or negative:
- Negative. A negative easement prevents or limits the property owner’s right to control or use his or her property with unlimited freedom. [For example, two townhouses are built adjacent to each other, and Townhouse A builds a sundeck on her roof to enjoy the sun. She can try to get an easement against her neighbor in Townhouse B to prevent him from increasing his building height in any way that may significantly block her sunlight.]
- Positive. A positive easement allows an individual or group to use the property of another property owner. This use must be for a specific purpose. [For example, Laura owns a ten-acre lot next to the lake. She sells a three-acre portion by the road to Brad, but Brad's land is blocked from the lake by Laura's remaining seven acres. As part of the sales agreement, therefore, Brad gets an easement to use a small roadway through Laura's property to access the lake. Brad can only use that easement to access the lake; he cannot build a guest cottage or garage on it, because his easement use is limited.]
An easement is a legal encumbrance upon a property and its ownership. Easements affect both the title to the property and the property’s physical condition
