D.C. Mun. Regs. tit. 10-A, § 1504
1504.1 ACS data shows that in 2017, just over half of the homes (50.4 percent) in the Capitol Hill Planning Area were row houses. This is more than double the District-wide average of 25 percent. Only four percent of the housing units were single-family detached homes, compared to 12 percent for the District as a whole. The area also contained fewer units in large apartment buildings than Washington, DC as a whole. Eighteen percent of Capitol Hill's housing units were in buildings with more than 20 units, compared to 35 percent District-wide. Conversely, Capitol Hill has more 2- to 4-unit buildings than the District as a whole—more than 15 percent in 2017 (compared to a District-wide average of 10 percent).
1504.2 The 2017 ACS data reported that less than eleven percent of the housing units in the Planning Area were vacant. The 2017 vacancy rate is slightly higher than the District-wide rate of nine percent.
1504.3 About half of all Capitol Hill households are homeowners, and half are renters, with percentages almost identical to the year 2000. The homeownership rate is higher than the District as a whole (41.2 percent).
