SAN ANSELMO’S GREEN BUILDING ORDINANCE

The Town of San Anselmo Green Building regulations for residential and commercial new construction and remodels became effective on September 9, 2020.

About Green Building Requirements for New Construction and Remodels

The Town has adopted Green Building requirements to reduce our use of energy, water and natural resources and improve San Anselmo citizens’ well being through improved indoor air quality, increased durability and greater comfort. Green building is the practice of taking an integrated approach to building construction, building systems, and building sites to provide more environmentally responsive, healthy, productive, economical places to live work and play. Green building techniques, which often reduce construction waste and costs, combined with new, higher efficiency materials and appliances, result in buildings which are less impactful on the environment and which save considerable energy and water costs throughout their useful life.
