Summary answer: The most documented change in Manassas is data-center growth in the city's industrial districts, which the city credits for much of its assessment growth, and new city rules for data centers that aim to protect nearby homes. Whether that raises values for a particular home is not something anyone can promise, and I do not predict it. What I can do is show you what is verified, what is only proposed, and how the Historic Overlay District rules affect renovating, so you can judge the risk and the timing yourself.
I'm Johnny with JQ Real Estate. Here is what the public record shows, with the status of each item.
What the public record shows
Three items are documented. First, the city manager's fiscal 2027 budget presentation said real estate values rose by $995 million, with $461 million tied to new construction, and attributed the growth largely to the data center industry, according to InsideNoVa. Second, on February 9, 2026, the city council gave unanimous first-reading approval to ordinance O-2026-455, which would set stricter standards for new data centers in the I-1 and I-2 industrial districts, including larger setbacks from homes, a pre-construction noise study, and screening of generators and cooling equipment, according to Potomac Local. I could not confirm that the second reading has passed. Third, the large Prince William Digital Gateway proposal of about 2,100 acres sits in Prince William County, not in the city, and the Virginia Court of Appeals voided its rezoning on March 31, 2026, and QTS withdrew its final appeal on July 2, 2026, which ended the project.
Status of each item
| Item | Status | What It Is |
|---|---|---|
| City assessment growth | Reported in the FY27 budget process | $995 million increase in real estate values, $461 million from new construction, largely data centers |
| Data center ordinance O-2026-455 | First reading approved February 9, 2026; final status not confirmed | Stricter setbacks, noise study and screening for new data centers in I-1 and I-2 districts |
| Prince William Digital Gateway | County project, not in the city | About 2,100 acres and 34 buildings proposed; the Court of Appeals voided the rezoning on March 31, 2026, and QTS withdrew its final appeal on July 2, 2026, ending the project |
| Historic Overlay District | In place | Exterior changes need Architectural Review Board approval |
What this means for a buyer
- Plans are not buildings. A proposed project or a first-reading ordinance can change or stall.
- Timing is uncertain. I did not find a verified schedule for new data center construction inside the city.
- Construction and operations are costs. A home near an industrial site can live with noise and traffic, which is why the city is writing noise-study rules.
- Value effects are not guaranteed. New commercial tax base can support city services, and I have no verified sold-price study for Manassas that shows how data centers affect nearby home prices.
The Historic Overlay District
Manassas has a Historic Overlay District, and the Architectural Review Board issues a Certificate of Appropriateness for construction, substantial exterior alteration, demolition, or relocation there. The board has listed items such as replacement siding or windows, fences, porches, and signs, and it has met at 5:30 p.m. on the third Tuesday of the month as needed. Confirm with Community Development at 703-257-8278. That protects the character of Old Town and the surrounding historic blocks and also limits what an owner can change, which matters if you want to renovate.
What the sales data says today
Redfin's data for Manassas over the three months ending August 2026 showed a median sale price of $511,661, up 2.3% from a year earlier, with 151 homes sold in August, up 23.6% from 122. The median home spent 39 days on the market, up 3 days, and sold at 101.0% of list. 44.3% of homes sold above list, up 10.7 points, and 28.4% had price drops, down 1.8 points. Median price per square foot was $286, up 6.5%. Redfin's Compete Score was 77 out of 100, which it labels very competitive, with an average of 3 offers per home, and it estimates the average home sells about 1% above list and goes pending in about 39 days, while hot homes sell about 2% above list in about 20 days. Redfin lists separate markets for Downtown Manassas, the Manassas Historic District, Point of Woods at Manassas, Wellington-Cloverhill Farm, Tara Wood, Westgate, Rixlew and Battery Heights Condominiums, so I check improvement at the block level using sold prices, days on market, and permit activity over the past two years.
How to evaluate a pocket yourself
- Compare the last three years of sold prices on the street against the city trend. The Federal Housing Finance Agency's all-transactions house price index for the City of Manassas was 206.34 in 2020 and 302.46 in 2025 on a scale where 2000 equals 100, a gain of 46.6% over five years, or about 7.9% a year. The 2025 annual change was +5.4%.
- Look at what is proposed within a mile and whether anything has a verified construction date.
- Walk the area at rush hour and on a weekend.
- Ask the city's planning staff what the zoning allows on nearby parcels.
- Run the monthly cost at the correct locality's tax rate.
An example
Suppose a buyer likes a townhouse a few blocks from Old Town and is deciding between it and a similar one a few miles away. The closer one costs about $20,000 more. The buyer checks the public record, confirms the home is outside any industrial district and inside the Historic Overlay District, and decides the premium is acceptable for the walkable location while planning for the review process on any exterior changes. A second buyer in the same position decides the quieter location is worth more. Neither is wrong, and both made the decision from facts rather than promises. The prices are an illustration.
