AI plan check in Washington, DC
AI-powered construction drawing review for Washington projects - checked against 2017 DC Construction Codes, the dcra (now dob) handles plan review, and the Washington permit process at the DC Department of Buildings (DOB).
For Washington, DC construction teams. Last reviewed May 2026.
Why Washington's Building Code Matters for Your Drawing Set
Washington construction projects are governed by 2017 DC Construction Codes based on 2015 IBC with DC amendments, enforced by the DC Department of Buildings (DOB). DCRA (now DOB) handles plan review. Height Act limits building heights. Historic districts cover large portions of the city. For a drawing set to make it through plan check without correction notices, the design must reflect both the base 2017 DC Construction Codes and the Washington-specific amendments - not just the model code. Local amendments matter most when they touch life-safety provisions (egress, fire-rated assemblies, accessibility) because those are the categories plan reviewers scrutinize most closely. The same drawing that would clear plan check in a city with only the base code adopted can draw a correction notice in Washington because of a local amendment the design team didn't catch.
How the DC Department of Buildings (DOB) Reviews Construction Drawings
Plan check at the DC Department of Buildings (DOB) follows a typical AHJ workflow: intake completeness check, first-pass plan reviewer assignment, discipline-specific specialist review (structural, MEP, fire/life-safety, accessibility), correction-notice cycle, and final approval. Washington's standard timeline of 4–12 weeks standard plan check reflects the volume the department processes and the typical correction-cycle count. Projects that arrive at the AHJ with un-coordinated drawings, missing sheets, or unresolved cross-discipline conflicts trigger longer timelines because each correction cycle adds days to weeks. Teams that pre-screen drawings with AI plan check before submitting catch most of these issues at the design stage, typically reducing AHJ correction cycles from 3-5 down to 1-2.
Common Plan-Check Issues in Washington
Washington construction drawings carry a specific risk profile tied to the city's construction context: height of buildings act limits most buildings to 130 feet; historic preservation review board governs many districts; green building act requires leed certification for larger projects; federal agencies (gsa, nps) may have jurisdiction; commission of fine arts review for some visible locations. Each of these conditions creates concrete design requirements that plan reviewers check for and that AI plan check can verify automatically. A drawing set that doesn't explicitly address the applicable conditions - for example, a Washington project that ignores the local construction conditions above - will draw a correction notice from the DC Department of Buildings (DOB), even if the rest of the design is sound.
Washington Project Types and What They Require
The dominant Washington project types are Federal government and Office/lobbying, with significant volume in Multifamily, Historic renovation, Mixed-use. Each project type triggers a different code-compliance footprint: residential and multifamily projects emphasize IBC Chapter 11 / ADA accessibility, IBC Chapter 10 egress, and IECC/Title 24 energy compliance; commercial and mixed-use projects add IBC Chapter 9 fire protection and NFPA 13/72 systems; industrial and logistics projects emphasize IBC Chapter 6 occupancy classification and high-pile storage requirements. AI plan check adjusts the rule set based on the project type and occupancy classification on the drawing set.
Washington Plan-Check FAQs
What building code does Washington use?
Washington, DC has adopted 2017 DC Construction Codes based on 2015 IBC with DC amendments. DCRA (now DOB) handles plan review. Height Act limits building heights. Historic districts cover large portions of the city. The Engineer of Record and Architect of Record should design to this adopted edition, including the local amendments, and the AHJ will review against the same.
How long does plan check take in Washington?
Standard plan-check timelines at the DC Department of Buildings (DOB) run 4–12 weeks standard plan check. Complex projects, projects with code variances, and projects requiring multiple discipline reviews can extend the timeline. Pre-screening drawings with AI plan check before submitting reduces the correction-cycle count and tends to shorten the overall timeline.
Who reviews construction drawings for permits in Washington?
The DC Department of Buildings (DOB) is the authority having jurisdiction (AHJ) for Washington, DC. Plan reviewers at the AHJ check submittals for compliance with 2017 DC Construction Codes based on 2015 IBC with DC amendments and the local amendments. The licensed plan reviewer retains the final approval decision under the adopted code.
What are the most common plan-check issues in Washington?
Washington projects most often run into plan-check issues tied to the city's specific construction context: Height of Buildings Act limits most buildings to 130 feet; Historic Preservation Review Board governs many districts; Green Building Act requires LEED certification for larger projects. Designs that don't explicitly address these conditions tend to draw correction notices and extend the permit timeline.
How does AI plan check work for Washington construction projects?
AI plan check parses every sheet in the drawing set in minutes and flags potential code-compliance and coordination issues against 2017 DC Construction Codes based on 2015 IBC with DC amendments, with citations to the specific sheet and code section. Findings are reviewed by the design team before submitting to the DC Department of Buildings (DOB), reducing back-and-forth correction cycles with the AHJ. AI plan check is a discovery and screening tool; the licensed Engineer of Record retains design responsibility and the AHJ retains approval authority.
What types of construction projects are most common in Washington?
The dominant project types in Washington are Federal government, Office/lobbying, Multifamily, with Historic renovation and Mixed-use also active. Each project type carries its own code-compliance considerations, and the AI plan check engine adjusts the rule set based on occupancy classification and project type.
