What Washington, D.C. homeowners should know
Washington's housing stock is old and dense. Rowhouses from the late 1800s and early 1900s fill neighborhoods like Capitol Hill, Shaw and Columbia Heights, with flat or low-slope roofs, shared party walls and original brick, so roof leaks, repointing and basement water are common projects.
Summers are hot and humid, and intense downpours can cause flash flooding in low-lying areas. Work in historic districts often needs review by the Historic Preservation Office in addition to a DC building permit.
