Solar Easements & Solar Rights Resources
Solar rights are cultural and legal rights to access and harness the rays of the sun. They can vary widely depending on where you live and local laws…
When solar rights enter the world of legal terminology, terms vary or shift with nuance. Below are three common terms and how they may be defined:
Solar Access – the ability to continue to receive and utilize sunlight on one’s property, across property lines, without obstruction from another property (e.g., buildings, trees, or other impediments)
Solar Easements – the right, expressed as an easement, restriction, covenant, or condition contained in any deed, contract, or other publicly recorded document assuring a landowner adequate solar access for solar energy systems and/or passive solar (lighting, cooking, growing crops, clothes drying, heating, and cooling) systems
Solar Rights – the ability to install and utilize solar-energy systems and/or passive solar systems on property subject to public or private land-use restrictions (e.g., homeowners association Declaration of Covenants, Conditions, and Restrictions (CCRs))

Living Building Challenge Imperative 18:Rights to Nature
The Living Building Challenge is the most sustainable, integrated green design certification I’ve come across, setting a much higher bar than LEED. You must meet or exceed 20 Imperatives/requirements. Imperative 18:Rights to Nature covers solar rights and solar access. The full Living Building Challenge 2.0 can be downloaded from the website below.
