The intervention group consisted of 16,133 non-elderly, nondisabled adults who were affected by the Santa Clara County Housing Authority (SCCHA) rent reform, across 7,111 households. (Elderly or disabled adults were also potentially affected but were not examined because their employment and earnings behaviors were assumed to be less flexible to the policy change). The comparison group consisted of 17,942 non-elderly, nondisabled adults representing 8,388 households selected from three other public housing authorities bordering Santa Clara County that had not implemented the rent reform as of July 2013 but might have been otherwise similar. These were the Housing Authority of the County of Alameda, the Housing Authority of the County of San Mateo, and the San Francisco Housing Authority. Evaluators compared employment and earnings outcomes before and after the onset of the policy change between SCCHA Housing Choice Voucher recipients and comparison Housing Choice Voucher recipients pooled together across the three comparison public housing authorities. The analysis relied on earnings and employment data from both groups dating back four years before the SCCHA rent reform and extending four years after the SCCHA rent reform. The intervention and comparison groups included those who had available administrative data on quarterly employment and earnings during this period.
The intervention was implemented in September 2013; evaluators measured outcomes through June 2017.
SCCHA
Beginning in September 2013, tenant contribution rates for families receiving Housing Choice Vouchers through SCCHA increased from about 27 percent to 35 percent of unadjusted income. (SCCHA subsequently reduced this rate to 32 percent one year later.) In addition, the new rent policy eliminated all allowances and deductions (for example, child care and medical expenses) for determining required contributions, and reduced the number of bedrooms on a household's voucher for some families. (Before the intervention, separate bedrooms were provided for household members older than age 5 in different generations, genders, or family relations; after the reform, one bedroom was allocated to the head of household plus partner and an additional bedroom was allocated for every two additional household members.) SCCHA offered a hardship exemption policy that allowed households to temporarily include child care or medical deductions in their tenant contribution for up to 90 days after the start of the rent reform. In addition, SCCHA provided financial assistance to cover rental payments or security deposits and free legal services to prevent eviction that might have resulted from the policy change.
The comparison group participants were selected from families receiving housing vouchers from the Housing Authority of the County of Alameda, the Housing Authority of the County of San Mateo, and the San Francisco Housing Authority. These neighboring county public housing authorities did not alter tenant contribution rate policies (which remained at about 27 percent of unadjusted income) during the intervention period.

The study took place in four neighboring counties in California: Santa Clara County, Alameda County, San Mateo County, and San Francisco County.
