Georgetown Historic District Renovation Permits Guide

Most Georgetown homeowners find out about the Old Georgetown Board the same way: they hire an architect, fall in love with a set of drawings, call a contractor for pricing, and then learn that the six-over-six windows they picked, the rear addition, the rooftop condenser and the new light fixture beside the front door all have to be reviewed by a federal advisory board that meets once a month and does not meet in August.

That is not a bureaucratic footnote. It is the single largest schedule variable in a Georgetown renovation, and in our experience it is the one homeowners underestimate by the widest margin. A project that could be built in five months routinely takes ten, and almost all of the difference is calendar, not construction.

If you are planning work in 2026 or breaking ground in 2027, here is how the review actually functions, what falls inside it, and how to plan a realistic schedule around it.

Georgetown is reviewed under two laws at once

This is the part that surprises people. Most DC historic districts are governed by the District’s own historic preservation law, administered by the Historic Preservation Office (HPO) and the Historic Preservation Review Board (HPRB). Georgetown is governed by that and by a separate federal statute that gives the U.S. Commission of Fine Arts (CFA) authority over exterior construction in the neighborhood.

In practice, the two systems divide the work:

The Old Georgetown Board (OGB) — an advisory panel of three architects appointed by the CFA — conducts the primary design review of most Georgetown projects and makes recommendations to the CFA, which issues the actual federal action.
CFA authority reaches construction that can be seen from a public street or alley. In a neighborhood of narrow lots, alleys and party walls, that captures the large majority of exterior work.
HPRB and HPO handle the remainder — the exterior work that is genuinely not visible from public space — under DC law.

Design review approval is a prerequisite for the DC Department of Buildings (DOB) to issue your construction permit. You are not “applying for a permit and also getting design review.” You are getting design review, and then a permit.

Where the district boundaries actually fall

The Georgetown Historic District runs from Rock Creek and Potomac Parkway on the east to Archbold Parkway on the west, and from Dumbarton Oaks Park and Whitehaven Street on the north down to the Potomac River. If your house sits inside that envelope, assume you are in. Do not assume a 1970s infill house or a heavily altered rowhouse is exempt — the district covers the geography, not the architectural pedigree of each building.

What gets reviewed (it is more than you think)

Homeowners generally expect additions and new construction to be reviewed. The list is considerably longer. Work that typically goes to OGB includes:

Windows and doors — replacement, material changes, changes to opening size, muntin pattern or operation
Additions, rear and side, and roof-level additions or dormers
Site work — walls, fences, gates, paving, steps, railings, terraces, and grading visible from public space
Mechanical equipment — condensers, mini-split heads and line sets, generators, vents, flues, gas meters, electrical meters and rooftop units
Roofing, where material, profile or visible detail changes
Demolition, full or partial — including removing a rear ell or a chimney
Exterior lighting and visible wiring
Signage and storefront work on the commercial corridors
Public space work in front of the property

Commonly outside review: minor repairs in kind, masonry repointing, underground utility work, and a change of use with no exterior modification.

Two categories deserve a specific warning. First, mechanical equipment. A whole-home HVAC replacement, a standby generator or a heat-pump conversion is not just an equipment decision in Georgetown — the location, screening and visibility of the unit is a design question, and it is common to have to move a condenser, build a screen, or re-route a line set after review. Second, windows. A vinyl or nail-fin replacement window that is unremarkable in Bethesda is frequently a non-starter here. Budget for wood or aluminum-clad wood units with appropriate profiles and true divided or simulated divided lites, and expect the sightline detail to be looked at closely.

The calendar is the project

Here is the rhythm to plan against. Confirm current dates with DOB and CFA before you rely on them — the schedule is published and does shift:

OGB meets monthly, typically the first Thursday, with no meetings in January and August.
Submissions are due roughly three weeks before the meeting, filed through the DC Department of Buildings.
The CFA acts on the OGB’s recommendation roughly two weeks after the OGB meeting.
Only then does the DOB permit review proceed to issuance.

Read that sequence again and you will see the trap: one clean round trip is about five to seven weeks from submission to CFA action. That is the best case, and it assumes the board recommends approval the first time.

It frequently does not. A first appearance often produces comments — reduce the addition’s height, revise the window detail, relocate the condenser, restudy the rear massing — and you come back the following month. Two or three appearances is a normal, non-catastrophic outcome for an addition. Three cycles, with the August gap in the middle, can consume half a year before a shovel moves.

There is also a useful two-stage structure. Concept review gets early design direction from the board before you have paid for full construction documents. Permit review is the later, detailed submission. Using concept review is generally cheaper than skipping it: finding out at the concept stage that a third-floor addition needs to step back is a drawing revision. Finding out at permit stage is a redesign.

Approvals do not last forever, but they last long enough to be useful: concept approval generally expires after two years, and permit approval after four if construction has not substantially started. That matters if you are approved now and want to build when rates, prices or your own timing improve.

What this means for a 2026 planning schedule

Work backward from when you want to break ground.

Break ground spring 2027 on an addition: you should be in design now, targeting concept review this fall and permit review over the winter. September through December gives you three or four board cycles before the January gap.
Break ground spring 2027 on windows, doors, roofing or mechanical: you have more room, but the fall cycles are the comfortable path. Waiting until February to start compresses everything into the spring bidding rush.
Any project you hoped to complete before the 2026 holidays: unless it is genuinely exempt interior work, that window has effectively closed. The honest answer is a 2027 build, well planned, rather than a rushed one.

The related point: the review calendar also protects you. A Georgetown project with a clean CFA action behind it is a project a good contractor can price tightly, because the design is settled. Bids on unapproved Georgetown drawings carry contingency for exactly this reason.

Budgeting realistically

We will not quote you a number we cannot stand behind, and Georgetown pricing varies enormously with condition, access and scope. But some planning ranges are fair to state as estimates:

Design and review support — architect, drawings, submissions and board appearances — commonly runs a meaningfully higher percentage of project cost than in non-historic work. Plan for it as a real line item, not an afterthought.
Historic-appropriate windows typically cost several times what a standard vinyl replacement costs per opening, before installation and any masonry or trim restoration.
Access and staging on narrow Georgetown lots — no driveway, restricted alley, public-space permits for a dumpster or scaffold — adds cost that suburban projects simply do not carry.
Latent conditions in 19th-century construction (failed brick, rotted framing at rear ells, knob-and-tube, undersized structure) are common enough that a contingency in the 10–20% range is prudent rather than pessimistic.

None of this is a reason not to renovate a Georgetown house. It is a reason to plan the money and the calendar honestly at the front, which is exactly what a well-run project does.

FAQ

Do I need Old Georgetown Board review to replace my windows? Generally yes, if the windows are visible from a public street or alley — and in Georgetown most are. Replacement in kind with matching material and profile is treated differently from switching material, changing the opening or changing the muntin pattern, but you should assume review is required and confirm with HPO or DOB before ordering anything.

How long does Georgetown historic review take? One clean cycle is roughly five to seven weeks from submission to CFA action, given the three-week submission deadline, the monthly meeting, and CFA action about two weeks later. Projects needing revisions commonly take two or three cycles, and there are no OGB meetings in January or August. Plan for months, not weeks.

What is the difference between the OGB, the CFA and HPRB? The OGB is a three-architect advisory board that reviews Georgetown projects and recommends action; the CFA takes the formal federal action on that recommendation. HPRB and the Historic Preservation Office administer DC’s own historic law and handle the exterior work not visible from public space. DOB issues the building permit only after design review is satisfied.

Can I put a condenser, mini-split or generator on my Georgetown house? Usually yes — but placement, screening and visibility are design questions subject to review, not just mechanical decisions. Getting equipment location reviewed early avoids paying twice to move it.

Does my approval expire if I delay construction? Concept approval generally expires after about two years and permit approval after about four if construction has not substantially started. If you are approved but not ready to build, note those dates and confirm them with CFA staff so you do not have to start over.
