Direct answer
What should a property decision-maker know in San Diego, CA?
San Diego methamphetamine residue planning must survive military PCS calendars, mesa dust loads, and canyon-edge multifamily pathways while still meeting California Health and Safety Code section 25400.16. Methamphetamine laboratory-activity indoor surfaces clear at ≤1.5 µg/100 cm²; fentanyl laboratory-activity surfaces clear only below detection until a health-based standard is adopted.

Local planning context
Mesa garden apartments, canyon-edge townhomes, and frequent military-family PCS handoffs create a high-turnover residue pattern distinct from quiet coastal villages. Cases appear after a vacant unit shows smoking debris, after a garage storage room yields solvent cans, or when a buyer’s inspector demands wipe PDFs before contingency removal. HSC 25400.16 supplies the statewide laboratory-activity reoccupancy rules: methamphetamine ≤1.5 µg/100 cm² on indoor surfaces (plus lead/mercury when those metals were used); fentanyl below detection until a health-based remediation standard is adopted. Santa Ana winds moving outdoor dust do not answer indoor wipe questions.
San Diego County Department of Environmental Health and Quality is the county environmental-health pathway for health-officer postings and orders after law-enforcement notification. DTSC removes bulk precursors found during raids; carpet pad and attic dust remain property-manager problems. Manufacturing expands hazardous-waste profiling. Use-only smoking still fails wipes on sofas and return grilles in sealed units. Courtyard carry paths without sealed bags reseed neighboring mats and entry tiles.
PCS move dates create intense schedule pressure. Property managers supporting military families still need laboratory comparisons before the next household occupies. Isolate the unit, map HVAC attic connections common in Southern California rows, and keep a turnover binder ready. Do not treat arid climate or open windows as clearance under California law.
