Marin County is a high-risk jurisdiction for utility-scale solar — documented ordinance hurdles are significant and approval history is mixed or unfavorable. The local regulatory environment has been trending more permissive over the past 12 months. California's state RPS policy provides a supportive macro backdrop for renewables, even where individual county ordinances are restrictive.
