Methods	Design: A cost analysis based on a before‐ and‐after study using administrative databases
Participants	Population: Homeless individuals who participated in the Housing for Health programme
Interventions	Intervention:
	Pre‐ and post‐ permanent supportive housing component of the Housing for Health programme
	Comparator:
	N/A
Outcomes	Cost or cost‐effectiveness: Permanent supportive housing was associated with an 80% reduction in emergency room visits, a 61% reduction in days spent as an inpatient, a 47% reduction in medical health outpatient visits, a 44% reduction in mental health outpatient visits, a 28% reduction in general relief receipt, and a two‐fold increase in days spent incarcerated; a 20% programme cost offset was observed for direct service costs for 1 year before housing provision versus 1 year after housing provision, suggesting that permanent supportive housing expenses might be partially offset by savings other Los Angeles county funds
