What Is a Solar Access Easement?
A solar access easement protects a path for sunlight to a collector or a lot, usually by limiting vegetation and structures on the neighbor’s land above a described plane. It is a written burden. A sunny yard without that document is only a sunny yard.

A plane across the neighbor’s air
The easement describes a volume the neighbor must not shade, often a plane or a series of angles above a lot line during set hours, for the benefit of a solar collector on the dominant lot. The servient owner keeps the ground and gives up the right to grow a tree or build a roof into that volume. Because the burden is easy to violate with an ordinary tree, the instrument has to be specific enough to locate. A note that says solar easement with no geometry is a warning light, not a plane you can enforce with a ladder. Read for heights, times of day, and which lots are dominant. If those terms are missing, the easement may be too vague to stake, and inventing the plane yourself is not a cure.
Plat notes and private grants
Some subdivision plats create solar easements on every lot in favor of the lot to the south, or whatever direction the designer chose. The note applies lot by lot. A private solar easement between two owners is recorded like any other easement and binds successors if it is appurtenant and properly drafted. A municipal solar ordinance is a different tool. It may protect solar access by permit rules without creating a property easement you can find in the deed. Do not cite the ordinance as if it were a recorded easement, and do not cite a handshake as if it were the ordinance. County GIS will not show a sun plane. Platbookmapper links to the parcel map only. It does not calculate sun angles or draw lot lines.
Trees and new construction
If you are the servient owner, a new gable or a fast-growing tree can enter the plane even when it respects the building setback. Setback and solar plane are different limits. If you are the dominant owner, the remedy for a violation is the remedy in the easement and the courts, not a chainsaw on the neighbor’s tree. Do not enter their lot. A phone inclinometer app is not a survey of the easement plane. If the plane must be located for a dispute or a design, a surveyor can tie it to the lot lines and a qualified person can relate it to the sun angles in the document. Until then, read the heights and keep new work below them.
What to do next
- Find the dominant and servient lots and the described plane or angles.
- Separate a recorded easement from a zoning solar rule.
- Check building height against both the setback envelope and the solar plane.
- Do not cut a neighbor’s tree under a self-measured angle.
The mix-up to avoid
Believing sunlight you have always enjoyed is a solar easement. Enjoyment is not a grant. Without a recorded easement or a statute that creates one, the neighbor may be free to build and to plant.
Questions people ask
Does a solar easement guarantee a working solar system?
It guarantees only the restriction it states, usually against shade from the servient lot. Clouds, your own trees, and buildings on lots that are not burdened are outside that promise. Read the beneficiary and the geometry.
Can the easement be moved if I move the panels?
Not by yourself. The plane was granted in a place. Moving the collector may put it outside the protected volume. An amendment both owners sign can relocate the easement. A new panel layout cannot.
Find the county map
The county GIS map is the practical place to start. Find it from the Platbookmapper directory, then treat the recorded plat and deed as the documents behind the picture.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
