Washington DC Compliance

Detailed for Washington DC, not adapted to it

Washington DC projects are dense, review-heavy, and often tied to rowhouses, party walls, basements, additions, commercial interiors, historic districts, zoning overlays, and tight site constraints. Generic drafting can miss the details reviewers look for, including egress, fire separation, accessibility, structural coordination, and clear site documentation.
Every Cadgency set is prepared with Washington DC permitting in mind. We organize sheets, details, notes, and revision responses around local AHJ expectations so residential and light commercial projects are easier to review, revise, and approve.

FAQ

Washington DC questions, answered

Many structural scopes, additions, commercial interiors, and permit submittals may require a DC-licensed professional depending on project type and local review. Cadgency prepares the drawing set and coordinates sealing when required.

Yes. We prepare drawings for Washington DC rowhouses, basements, additions, accessory spaces, tenant improvements, and interior build-outs with clear notes for local review.

Typical residential permit sets run 5 to 10 business days depending on scope, existing information, and review requirements. As-builts, tenant improvement updates, and single-sheet revisions are usually faster.

Whatever you have: hand sketches, photos, an old plan set, lease plan, site notes, or just a conversation about what you want to build. We take it from there.
