Solar and Wind Easements & Rights Laws & Local Option Solar Rights Law
You are here
Oregon's solar and wind easements provisions allow property owners to create solar and wind easements for the purpose of protecting and maintaining proper access to sunlight and wind. Easements are negotiated with neighboring property owners. Oregon's solar easement law was enacted in 1979; the wind easement law was enacted in 1981.
Oregon state law also allows municipalities and local authorities to establish solar access laws. Access laws are intended to protect solar access to the south face of buildings during solar heating hours, taking into account existing development, vegetation, and planned uses. The local ordinances may include standards for orientation of new streets and lots, placement and height of new buildings, and the placement of new trees on public property. City and county laws are generally designed to protect south-facing roof space for active solar energy systems such as solar electric and solar hot water panels, as opposed to daylighting and passive solar heating that require southern exposure to a building's wall.
