Key takeaways:
- Downtown's commercial core has been a National Register historic district since 2021.
- Building permits, zoning and code questions each go to a different city contact, all listed below.
- With Courthouse Square construction running through late 2027, nearby owners may want a dated record of their buildings.
Washington, the county seat, fits 13,176 residents (2020 census) into 2.92 square miles around the Washington County Courthouse. CAD Construct LLC provides 3D laser scanning, as-built drawings, Revit models and 360° tours for downtown buildings, campus work and civic projects in the city.

Scanning Downtown Washington, PA
Downtown's commercial core became the Washington Commercial Historic District when it was listed on the National Register on May 6, 2021. The district is roughly bounded by Spruce, Park, Shaffer and Bownson avenues and Franklin Street, and its period of significance runs from the late 18th century into the early 20th. Commerce grew after the National Road reached Washington in 1818, and a second building surge around 1900 followed the growth of coal, oil and gas.
That history left storefront blocks with additions from several eras, shared walls and upper floors that have sat empty or been converted. When an owner plans upper-floor apartments or a facade repair, a measured set of plans and elevations is usually the first thing the architect asks for.

Deliverables for downtown and campus work
- A registered point cloud covering a whole block face and its interiors
- 2D CAD plans, elevations and sections for permit and design sets
- When engineers need structure and systems as objects, a Revit model
- 360° tours that let a buyer or tenant walk a storefront from anywhere
Owners on Main Street weighing a sale or refinance can also use a real estate scan to confirm square footage before closing.

The Courthouse and Courthouse Square
The Washington County Courthouse at 1 South Main Street was completed in 1900 to a design by Frederick J. Osterling. It is built of sandstone, granite, iron, steel and brick, and its stained glass ceiling measures 40 feet across. The dome had interior rehabilitation in 2013 and waterproofing and exterior repairs in 2019. In February 2026, the commissioners put leak repair and restoration out to bid and sought a $100,000 PHMC grant for an engineering assessment, because the sources of the leaks could not be found.
Problems like that are where scan data helps an engineering team. A point cloud of a dome's interior and exterior surfaces lets engineers check joint lines, flashing and drainage paths from the office, and repeat scans can show change over time. Our historic documentation guide explains how the data is packaged for preservation review.
At Courthouse Square, demolition of the six-story former county office building and garage began on March 2, 2026, with Adamo Demolition holding a $1.555 million bid plus a $1.44 million wall-shoring contract. The new three-story public safety building on that site, designed by AE Works with Gateway Engineers, broke ground the week of September 10, 2026, with $41.2 million in construction contracts and completion expected in late 2027. It will house 911 dispatch, the sheriff, and county and court offices, behind a facade designed to match the Crossroads Center across West Beau Street.
Wall shoring beside a demolition is the kind of work where adjacent conditions matter. Scanning neighboring facades and the excavation edge before and during work gives contractors a measured record for construction verification and for answering neighbors' concerns.
Catfish Creek and South Main Street
South Main Street has also been closed for reconstruction of the Catfish Creek culvert bridge by Golden Triangle Construction. Pennsylvania American Water began relocating its mains on September 8, 2025, and the project was expected to wrap up in fall 2026. Culverts and short-span bridges can be scanned before and after reconstruction to record clearances and alignment; see our bridges and infrastructure page.
Washington & Jefferson College and the President's Pathway
W&J's oldest building, McMillan Hall, dates to 1793, and the college calls it the eighth oldest academic building in the United States. It has been on the National Register since 1977. Campus buildings of that age pair original masonry with generations of mechanical and accessibility upgrades, so design for the next upgrade starts with measured existing conditions. Our schools and campuses page covers that work.
The college's next residence hall, a four-story, 51,500-square-foot building for about 220 students designed by Kimmel Architecture, is planned off East Chestnut Street in East Washington Borough rather than the city itself, with an opening set for fall 2027. Closer to downtown, the Washington Business District Authority received a $60,000 Main Street Matters grant and about $160,000 in reallocated LSA funds for the President's Pathway, a lighted walkway linking W&J to downtown.
Historic Houses and Landmarks in the City
The city has 11 National Register listings, among them the David Bradford House (listed 1973), the F. Julius LeMoyne House (1997), the Washington County Jail (1974), the Washington Armory (1991), the Pennsylvania Railroad Freight Station (1995) and the Washington Trust Company Building (2015). Each type brings a different documentation need. A house museum calls for detailed elevations and molding profiles, while a freight station or armory being studied for reuse needs a clear record of its long-span structure.
For buildings in the historic district or on the Register, a scan supplies the drawings a preservation consultant needs without touching original fabric. See historic preservation scanning for the deliverables.
Permits and Code Contacts in Washington, PA
The City of Washington adopts and enforces the Pennsylvania Uniform Construction Code under Chapter 130, Article VII of the city code, which also establishes a board of appeals. City Hall is at 55 West Maiden Street (724-223-4200).
- Building permits: Municipal Consulting Services, the city's third-party agency (Harold Ivery Jr.), 724-263-0377
- For zoning and planning, Harshman CE Group LLC, also a third-party agency, at 724-993-4505
- Code questions go to the city Code Enforcement Officer, Alyssa Beachy, at 724-225-2785
Landlords should know the city also runs a rental registration program. Measured as-builts make permit drawings faster to prepare, but requirements change, so confirm with these offices before submitting; this is general guidance, not legal advice. Permits elsewhere in the county are covered on our Washington County page.
Accuracy and Pricing for City Projects
Only 44.6 percent of the city's housing is owner-occupied, so many projects here involve rental buildings and small commercial properties where the owner needs just enough detail for a permit or a lease. A scan of a carved stone cornice for a restoration needs a much tighter tolerance than that. We state the tolerance for each project using USIBD Level of Accuracy (LOA) bands and match the scanner and software to the building. Pricing follows the scope, and the as-built cost calculator gives a starting range. Public owners can also note that CAD Construct holds DBE certification through the Pennsylvania Unified Certification Program.
