Recycling and Diversion of Debris from Construction and Demolition Ordinance No. 4099

This document is a municipal ordinance enacted by San Mateo County establishing mandatory recycling and debris diversion requirements for construction and demolition projects in unincorporated areas. The ordinance applies to contractors performing construction, demolition, remodeling, renovation, or landscaping services on buildings and accessory structures. Covered projects include demolition work exceeding $5,000, renovations or new construction exceeding $250,000, commercial or residential development projects, and any new structure of 2,000 square feet or greater. All contractors must submit a Waste Management Plan as an integral part of the building or demolition permit application process prior to project commencement. The plan must identify intended salvage, reuse, and recycling facilities selected from a County-approved list. Building Official approval of the Waste Management Plan is a condition precedent to permit issuance. Within 30 days of project completion, contractors must submit documentation demonstrating compliance, including photocopies of receipts, weight tags, and records from recycling companies, deconstruction contractors, and disposal facilities. Progress reports during construction may be required.

The ordinance mandates diversion of 100% of inert solids and at least 50% of remaining construction and demolition debris tonnage. Contractors may comply through two options: directing all mixed construction and demolition debris to County-approved facilities, or source-separating non-inert materials such as cardboard, paper, wood, metals, and green waste for recycling while limiting remaining material to disposal facilities. Contractors are encouraged to perform deconstruction and salvage operations prior to demolition, with salvaged materials counting toward diversion requirements. An administrative fee, established by County resolution, is required as a condition precedent to permit issuance. Violations constitute misdemeanors punishable by imprisonment up to six months, fines up to $1,000, or both, with each day of violation considered a separate offense. Submitting false documentation regarding tonnage, recycled materials, or fraudulent receipts is unlawful. The Building Official has authority to enforce the ordinance and order work stoppage for violations.
