District of Columbia Building Permit Timelines & Delays
Washington, D.C. is a jurisdiction unlike any state: a unified city-state where a single agency, the Department of Buildings (DOB), runs building permitting, plan review, and inspections across the entire District. There is no state-versus-local split. DOB, created in October 2022 when the former DCRA was divided into two agencies, enforces the District's own Construction Codes (DCMR Title 12), currently the 2017 DC Construction Codes based on the 2015 I-Codes (effective May 29, 2020).

What the data shows
Washington, D.C. is a unified city-state jurisdiction: a single agency, the Department of Buildings (created in October 2022 from the former DCRA), runs building permitting, plan review, and inspections across the entire District, with no state-versus-local split (DC Department of Buildings).
The District enforces its own Construction Codes (DCMR Title 12): the current edition is the 2017 DC Construction Codes, based on the 2015 I-Codes, effective May 29, 2020 (DC DOB).
DOB's own clock is fast: it met every FY2024 plan-review target, reviewing about 97% of filed ProjectDox permit applications within 30 business days against a 90% target (DC DOB, FY2024 Performance Accountability Report).
The distinctive friction is federal and historic, layered on top of DOB: the congressionally imposed Height of Buildings Act caps most commercial buildings at about 130 feet (90 feet on residential streets), and only Congress can change it (Height of Buildings Act; NCPC).
Roughly one in five buildings sits in a historic district subject to Historic Preservation Office and Review Board review before a permit can issue, and private construction near federal-interest areas faces Commission of Fine Arts review under the Shipstead-Luce Act. The District authorized about 1,737 units in 2024, roughly 87% of them multifamily (D.C. Policy Center; U.S. Census, 2024).
Most delay accumulates before technical review
The data points to the same lever everywhere: most delay accumulates before technical review, in completeness and resubmittal cycles. Permittable's Permit Review Diagnostic checks your plans against applicable codes and common reviewer issues before you submit — so your package is more likely to clear on the first pass.
District of Columbia permitting: FAQ
Does Washington, D.C. have its own building code?
Yes. The District enforces its own Construction Codes (DCMR Title 12), which adopt the I-Codes with DC amendments; the current edition is the 2017 DC Construction Codes, based on the 2015 I-Codes and effective May 29, 2020 (DC DOB). Because DC is a unified city-state, those codes apply jurisdiction-wide, administered by a single agency rather than split between a state and local governments.
Who issues building permits in DC?
The Department of Buildings (DOB), which was created in October 2022 when the former Department of Consumer and Regulatory Affairs (DCRA) was split into two agencies. DOB is the single building authority for the entire District, handling permit applications, plan review, and inspections citywide (DC Department of Buildings).
How fast is DC permitting?
DOB's own review is fast: its standard for filed projects is 30 business days, and in FY2024 it reported reviewing about 97% of ProjectDox applications within that window, beating its 90% target (DC DOB, FY2024 PAR). The longer pole is usually the federal and historic review that sits on top, not DOB's queue.
What federal rules affect building in DC?
Two big ones. The federal Height of Buildings Act caps most commercial buildings at about 130 feet (90 feet on residential streets), and only Congress can change it (NCPC). And private construction near federal-interest areas, including the National Mall, the White House, and Pennsylvania Avenue, faces Commission of Fine Arts review under the Shipstead-Luce Act, on top of the District's own historic-preservation review.

DOB's percent-on-time and volume figures are agency self-reported metrics from its FY2024 Performance Accountability Report, measuring DOB's own review clock only; they exclude time in historic, federal, or zoning review and applicant resubmissions. The current code is the 2017 DC Construction Codes (2015 I-Codes); confirm against DOB before relying on it, since the District updates on its own cycle. The one-in-five historic-district figure is a D.C. Policy Center estimate, not a government statistic. The 1,737-unit figure (about 87% multifamily) was verified directly from the U.S. Census Building Permits Survey 2024 file.
