Pittsburgh historic districts: when exterior work needs a Certificate of Appropriateness, and what it means for your contractor

Exterior work on a house in one of Pittsburgh's 16 local historic districts needs a Certificate of Appropriateness (COA) from the City before a building or demolition permit is issued (City of Pittsburgh, Apply for Historic Review, read 23 October 2026). That step sits in front of the permit timeline our data measures: the usual Pittsburgh remodel, windows and alteration permit reached final 178 days after issue, out of 1,902 permits from October 2023 to September 2026.

Is your house in a district?

The City's Historic Designations and Districts page (read 23 October 2026) lists 16 local districts, 67 individual designations and 2 sites (Schenley Park and Westinghouse Park). The districts:

A to E L to M M to O P to S
Allegheny Commons Park Lemmon Row Mexican War Streets Penn Liberty
Allegheny West Manchester Mexican War Streets Expansion Roslyn Place
Alpha Terrace Market Square Murray Hill Avenue Schenley Farms
Deutschtown Oakland Civic Center
East Carson Street Oakland Square

The page says its list is still being updated and that the interactive map linked at the top is the most current check, so look the address up on the map before you get quotes. A National Register listing is not the same thing: these rules come with City designation.

The three review tracks

The City sorts COA applications into three tracks:

Track What goes in it Who decides
Accessory Structure Review Exterior site work, fences, features the district guidelines do not call character-defining Staff, or the HRC if staff cannot approve
Basic Review Exterior alterations with no new construction or addition: in-kind or guideline-recommended window and roof replacement, repair of exterior materials Staff over the counter for some; otherwise the HRC
Large Project Review Demolition, new construction, additions Historic Review Commission; a briefing first is recommended

The COA Process Guide (version 2026-08-27) gives the over-the-counter example plainly: exterior repair where "color, size, texture, shape, and composition of building materials remain unchanged." Swap slate for asphalt, wood windows for vinyl, or change a paint color, and you are past that line. The guide also asks for paint colors on the material sheets, so color is part of what gets reviewed.

Dates that set your schedule

  • HRC meetings: 1:00 pm, the first Wednesday of each month; agendas post 10 days before.
  • Community meeting: if the site is in a Registered Community Organization's area, a Development Activities Meeting is required 30 days before the HRC meeting.
  • Zoning first: if the project needs the Zoning Board of Adjustment, that decision must be issued before the HRC meeting is scheduled.
  • Outcomes: approve (with or without conditions), postpone, or deny. After a denial you can revise, apply for a Certificate of Economic Hardship, or appeal to the Court of Common Pleas.

Fees are on the City's fee schedule and are non-refundable; the guide says more may apply for HRC review. We did not find a dollar figure on the pages above, so ask staff at historicpreservation@pittsburghpa.gov.

What it means for hiring a contractor

  1. Put the COA in the contract. Who prepares the application (narrative, photos, drawings, material sheets, site plan for additions) and who attends the HRC meeting. A contractor who has done district work will know the guidelines for your district.
  2. Ask for materials by name. The Commission reviews what is on the spec sheet. A quote that says "replacement windows" without the product cannot be reviewed.
  3. No permit before the COA. The City will not issue the building or demolition permit until the COA exists, so a crew that starts first is starting without a permit. PLI can cite the work.
  4. Check the license. Pittsburgh requires a City general contractor license for building work, with an owner-occupant exemption; see Pittsburgh remodel permit and Pittsburgh contractor license lookup.

What Pittsburgh permits show

Measure Remodel, windows & alteration Demolition
Permits, October 2023 to September 2026 1,902 368
Firms 549 57
Usual filed value $12,500 $26,900
Usual days, issue to final 178 119
Finished (permits a year or more old) 62.3% 92.5%
Firms with a single permit 63.0% 49.1%
Busiest month June July

Two things matter for a district job. First, 63.0% of remodel firms filed only one permit in three years, so many of the names you will be quoted have little Pittsburgh record to check. Second, remodel permits peak in June (index 127, 100 = an average month). Work back from that: to start in early summer, the COA has to be on a spring HRC agenda, which means a complete application in late winter.

Five-minute check

  1. Find the address on the City's historic map.
  2. Ask the contractor for two past addresses in a district and look up their permits as in Pittsburgh building permit search.
  3. Open the firm's page from our Pittsburgh remodel list and compare its finished share with the 62.3% citywide figure. Typical prices are on the Pittsburgh remodel cost page; counts by year on Pittsburgh permit statistics.

What this does not tell you

Our file does not flag which permits are in historic districts, so the table covers the whole city. COA applications themselves are not in it.

How we know this

The rules are from the City of Pittsburgh's Apply for Historic Review page, the Certificate of Appropriateness Process Guide (version 2026-08-27) and the Historic Designations and Districts page, read 23 October 2026. Permit counts are City of Pittsburgh permits on homes in our remodel, windows and alteration and demolition categories, October 2023 to September 2026; the finished share uses permits a year or more old.

Numbers come from City of Pittsburgh permits (Western Pennsylvania Regional Data Center), data through October 12, 2026. Nobody paid to be on this page and nobody can.

Questions

  • Do I need approval to replace windows in a Pittsburgh historic district?

    Yes. Exterior work on a property in a City-designated historic district needs a Certificate of Appropriateness. In-kind or guideline-recommended window and roof replacement goes through the Basic Review track, and staff can approve some projects over the counter.

  • How many historic districts does Pittsburgh have?

    The City's Historic Designations and Districts page lists 16 local historic districts, including the Mexican War Streets, Manchester, Deutschtown, Allegheny West, Schenley Farms and East Carson Street, plus 67 individual designations and 2 sites.

  • When does the Pittsburgh Historic Review Commission meet?

    At 1:00 pm on the first Wednesday of each month. Agendas are posted 10 days before the meeting, and an incomplete application cannot be put on an agenda.

  • What happens if I do work without a Certificate of Appropriateness in Pittsburgh?

    The City says violations can be cited by the Department of Permits, Licenses, and Inspections and are handled like other building code violations. A COA is also required before a building or demolition permit is issued.

  • How long does a remodel permit take in Pittsburgh?

    In our Pittsburgh remodel, windows and alteration file the usual permit reached final 178 days after issue. Add the COA step before that if the house is in a historic district: Commission review happens once a month.
