1. Permanent housing subsidy, or SUB, usually a housing choice voucher (HCV), could include assistance to find housing but no other supportive services.

2. Community-based rapid re-housing, or CBRR, provides temporary rental assistance, potentially renewable for up to 18 months, paired with limited, housing-focused services to help families find and rent conventional, private-market housing.

3. Project-based transitional housing, or PBTH, provides temporary housing for up to 24 months in agency-controlled buildings or apartment units, paired with intensive supportive services.

4. Usual care, or UC, is defined as any housing or services that a family accesses in the absence of immediate referral to the other interventions. This intervention typically includes at least some additional stay in the emergency shelter from which families were enrolled.
