San Luis Obispo County, CA Building Safety: Green Building Code (2026)

040 requires new homes larger than 2,500 square feet to submit a green building checklist with the building plans, verified at construction by a letter from the project's architect or engineer: either Green Point Rated at a minimum of 75 points, or LEED for Homes at a minimum of 40 points, in both cases without exceeding current Title 24 Part 6 energy standards. 050 sets the same structure for non-residential construction over 10,000 square feet, requiring LEED Certification at 40 points or CALGreen Tier 1.

Neither section requires third-party inspection or certification; the Architect or Engineer of record's letter is enough. 060 layers on a construction and demolition waste program: applicants must submit a waste management recycling plan at permit application listing the project owner, location, contractor, estimated debris volume by material type, and the vendor who will collect it, then divert at least 75 percent of all debris generated, with the county's goal set at 80 percent as facilities allow. Before final inspection, the applicant must submit a disposal report with vendor receipts, photographs of on-site reuse, and a completed accounting of diverted versus landfilled material, measured by weight wherever practical.

1. 090 allows a hardship or infeasibility exemption where compliance would conflict with other code provisions, cost is disproportionate to the project, or green materials are not commercially available, with the chief building official setting the maximum feasible compliance threshold. 080.
