Concrete work is not a District-licensed occupation (D.C. Code § 47-2853.04). Residential driveways, patios, porches, and private walks for $300 or more are home improvement work — 16 DCMR § 899.1 names driveways, porches, and decks — so the contractor needs a basic business license with the Home Improvement Contractor endorsement, a $25,000 bond (16 DCMR § 802.1), and liability insurance (16 DCMR § 803.2). Foundations for new buildings, commercial flatwork, and land development fall under the GC/CM endorsement (17 DCMR § 3999.1).
DOB exempts in-kind replacement of private sidewalks, driveways, and patios from a building permit outside historic districts, but new driveways and retaining walls over 4 feet need permits. Sidewalks, driveway aprons, and curb cuts in public space need a DDOT public space permit, and DOB routes projects involving soil disturbance to DOEE for review.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
The District has no separate county or city layer: DLCP issues the business license and trade licenses, DOB issues building and trade permits and inspects, and the Office of Planning's Historic Preservation Office must clear permits for exterior work on historic landmarks and in historic districts (D.C. Code § 6-1105). Work in public space — sidewalks, driveway aprons, dumpsters — needs a DDOT public space permit. In historic districts, work otherwise exempt from a permit (or eligible for an instant permit) still needs review.
The local offices section below names the exact permit desk for every District of Columbia county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
The District licenses this trade as a business — bond, insurance, background paperwork — with no exam or experience requirement.
In-kind replacement of a private driveway or patio is permit-exempt; anything past the property line is public space and needs DDOT.
Retaining walls over 4 feet (bottom of footing to top) need a DOB permit.

Pending verification: Late-renewal penalties: D.C. Code § 47-2851.10 (as amended through D.C. Law 26-183, Sept. 25, 2026) sets $75 within 30 days, $150 from 30 days to 6 months, and $350 after 6 months, while DLCP's fee summary lists $75, $75, and $200 — DLCP's page appears stale · Whether any separate endorsement or application charge applies on BOSS beyond the $49 / $99 / $198 term fee; § 47-2851.03(c)(2) says endorsements carry no cost, but older DLCP endorsement pages listed higher totals and could not be opened (access denied) · DLCP publishes no trade-by-trade list of which residential jobs it treats as 'home improvement work'; the 16 DCMR § 899.1 definition (repair, replacement, remodeling, improvement of residential property) is applied here · 16 DCMR ch. 8 and 17 DCMR ch. 39 still name the DCRA Director; the functions moved to DLCP on October 1, 2022 — no amended regulation text was located · The DOEE erosion and sediment control threshold for land disturbance (DOB's retaining-wall guidance references 50 square feet; the DOEE regulation was not retrieved) · DDOT public space permit fees for driveway aprons and sidewalks (DDOT fee schedule not retrieved)
