Steps
Confirm the project type is covered — CalGreen Sections 4.408 (residential, mandatory) and 5.408 (nonresidential) apply to most new construction, demolition, and certain addition/alteration permits
Under Section 4.408.1, plan to recycle and/or salvage a minimum of 65% of nonhazardous C&D debris generated by the project, per the standard compliance path
Prepare and submit a Construction Waste Management Plan (per Section 4.408.2) prior to building permit issuance, signed by the owner, describing materials to be diverted and the diversion method
If using the weight-based alternative compliance path instead of the 65% method, confirm the current per-square-foot disposal thresholds in Section 4.408.4/4.408.4.1 with the local enforcing agency, since these figures are periodically revised between code cycles
Check with the local jurisdiction (city/county) for any locally amended C&D ordinance that layers additional reporting or a higher diversion rate on top of the state CalGreen minimum
Known gotchas
CalGreen sets a statewide floor — many California cities and counties (e.g., via local C&D recycling ordinances) impose stricter local diversion rates or additional reporting on top of the 65% state minimum; always check local amendments, not just the state code
The alternative per-square-foot weight thresholds under 4.408.4 are code-cycle-specific numbers that have changed between recent CalGreen revisions — confirm the currently adopted figure with the local building department rather than citing an older cycle's threshold from memory
