Siding replacement in DC’s historic districts, done the right way
Washington has 37 residential historic districts, and each one places real limits on siding material, color, and installation method. This guide walks through the review process, the agency each district reports to, and what to ask before you hire — neighborhood by neighborhood.
How review actually works
Every historic district in DC follows some version of this sequence. The details differ by neighborhood, but the shape of the process doesn’t.
Confirm your district and reviewing body
Almost every district reports to the Historic Preservation Review Board (HPRB) through the Historic Preservation Office (HPO). Georgetown is the one exception — it’s reviewed by the U.S. Commission of Fine Arts (CFA) through the Old Georgetown Board.
Find out if your job is “in-kind” or a material change
Repairing or replacing siding with a matching material is often reviewable administratively, sometimes within a day or two. Switching materials — wood to fiber cement, for instance — usually needs full HPRB or CFA review, especially on a front facade.
File before you sign a contract
Permit applications go through DC’s Department of Buildings alongside historic review. Don’t commit to materials or a install date until you know what’s approvable on your specific elevation.
Hire a contractor who’s done this before
Historic-district experience shapes how an application is documented, how materials are sourced, and how realistic your timeline is. It’s the single biggest variable in how smoothly this goes.
Official agencies and review boards
These are the bodies with real authority over your project — not a contractor’s opinion, not a neighbor’s guess.
Historic Preservation Office (HPO)
Staff review for all districts except Georgetown’s public-facing work. Start here for pre-application questions.

A contractor’s answers to these tell you more about how your project will go than any brochure.
- Have you filed a Historic Preservation application in DC before — and can you show me an approved example?
- Do you know whether my district is reviewed by HPRB or the Old Georgetown Board/CFA?
- Will this be treated as in-kind repair or a material change, and how does that affect the timeline?
- Who is responsible for preparing and submitting the permit and historic review application — you or me?
- What happens if the application is denied or sent back with conditions — is that built into your quote?
- Can you source or match the specific material, profile, and reveal my district’s guidelines call for?
- Is your estimated timeline based on administrative approval, or does it assume full board review?
- Do you have references from jobs completed specifically inside a DC historic district?
Find your neighborhood
Each entry links to that district’s official map and design documentation from the DC Office of Planning. Not every property inside a boundary is automatically a “contributing” historic structure — confirm your specific address with HPO if you’re unsure.
Siding guidance by district
Architecture, era, and material norms vary block to block even within one district — treat these as a starting orientation, then confirm specifics against your district’s design guidelines document before you finalize material choices.
