San Diego’s Supplemental Development Regulations passed initially in 1997 but since has had many additions and alterations, some as recent as 2020. San Diego’s Supplemental Development Regulations require that a “Shadow Plan” be developed when it is determined that structures or landscaping within a proposed development may have an impact on neighboring property’s access to solar exposure. This is intended to ensure that potential impacts to solar access will be minimized. (§143.0410 section i)
The Shadow Plan is further fleshed out in §151.0301 – Permitted Development Controls. Detailing that “when, in the opinion of the City Manager, structures and major landscaping at maturity for a development project may have an impact on the solar access of adjacent property, the applicant shall submit a satisfactory shadow plan prior to the approval of a planned district development permit” (6.A).
