What shapes a District of Columbia project
Exterior work needs HPRB review + authentic materials. The biggest cost + timeline factor.
Party-wall + rear-addition rules; membrane roofs need expertise; old systems hide surprises.
Certified contractors required. Budget $300-$1,500 per project.
Timelines are permit-bound. Complete drawings avoid correction cycles.
Licensed trades mandatory; little DIY. The same project costs far more than in the suburbs.
Standard footings, though most DC work is within existing rowhouse footprints.
