Montgomery County's construction report lists 3,006 apartment units under construction at the end of September, up 29.7% in a quarter

Montgomery County's list of large construction projects held 3,006 apartment and condominium units under construction on September 30, 2026, according to the third-quarter Quarterly Construction Report from the Montgomery County Planning Commission and the county Commerce Department. That total, summed from the report's project table, is 688 units more than the 2,318 listed at the end of June, a rise of 29.7%, and 577 more than the 2,429 listed a year earlier. Three projects with 950 units between them joined the list at the construction stage. No project of 50 or more apartments was listed as complete in the quarter, and 173,741 square feet of nonresidential space was completed.

The report is an inventory of the county's larger jobs. A project appears when it has at least 50 multifamily units, meaning apartments or condominiums in a shared building, or at least 30,000 square feet of new nonresidential space. Each edition lists the project's municipality, address, size and phase: land preparation, construction, holding or complete.

What joined and left the listThree projects with 950 units joined the list in the quarter

Three projects appear for the first time, all at the construction stage. Parkside Providence Town Center, Buildings C through E, in Upper Providence has 419 units. The Piazza at Ardmore in Lower Merion has 270 units in a mixed-use project. Phase III of the Willow Grove Shopping Center redevelopment in Upper Moreland has 261 units and 34,650 square feet of commercial space. Shoshanna's Way in Whitpain, 56 age-restricted units, also joined the list at the land preparation stage.

One large project left the construction stage. River Pointe (Bridgeview) in Bridgeport, with 348 single-family attached units and 262 multifamily units, was listed under construction in each report from the third quarter of 2025 through June. The September report lists it as holding for the multifamily portion. The report gives no reason for the change.

The Kenrick apartments in Norristown are on the report's cover, in a photo of a sign that reads "now open." The table still lists Arbor Place/the Kenrick, with 125 single-family attached and 192 multifamily units, under construction as of September 30.

Nonresidential workThirteen nonresidential projects held 1,722,663 square feet under construction

Thirteen nonresidential projects totaling 1,722,663 square feet were under construction at the end of September. Industrial buildings made up 1,072,549 square feet of that across seven projects, led by SPS Technologies in Abington at 348,734 square feet and the Kraussdale Road warehouse in Upper Hanover at 249,760. Two institutional projects, the Montco Justice Center in Norristown at 325,000 square feet and the Penn Medicine ambulatory health center in Montgomery Township at 150,000, accounted for 475,000. Four commercial projects added 175,114.

Two lab buildings joined the list. The report lists a 120,000-square-foot Merck bioanalytical facility in Upper Gwynedd and a 91,955-square-foot Johnson & Johnson lab building in Lower Gwynedd, both industrial and both under construction. The District at Black Rock in Upper Providence, 148,430 square feet of commercial space, is listed at land preparation.

The quarter's 173,741 square feet of completions came from three institutional buildings: the Penn State Abington academic building at 85,554 square feet, the first phase of the Encompass Health rehabilitation hospital in Lower Providence at 56,187, and the Mount Saint Joseph's Academy expansion in Springfield at 32,000.

Conshohocken and the nearby townshipsWashington Street's 481 units are 16% of the county's total

The largest job near Conshohocken on the list is 401 and 433 Washington Street, 481 multifamily units in Conshohocken. It has been listed under construction in every report since at least the third quarter of 2025 and holds 16% of the units under construction countywide, second only to the 500 age-restricted units at Shannondell at Valley Forge in Lower Providence.

Lower Merion has three projects under construction with 781 units: 111 Presidential Boulevard with 425, The Piazza at Ardmore with 270 and 206-216 Bala Avenue with 86. That is 26% of the county total. In Whitemarsh, the BMW of Fort Washington expansion, 69,182 square feet of commercial space, has been listed under construction since the second-quarter report. The September list has no project in Plymouth, Upper Merion or West Conshohocken. The last large job in Upper Merion, a 112,500-square-foot warehouse at 529 Hertzog Boulevard in King of Prussia, was listed complete in June.

Smaller jobs fall below the report's thresholds. Conshohocken Borough Council's November 4 agenda includes a resolution on preliminary and final approval for the Maple Street Development Project at 18, 38, 42, 44 and 46 Maple Street. The application in the borough's July 9 planning commission packet describes 12 new townhouses, three rebuilt row houses and one new single-family house on 1.02 acres. A job of that size will not appear in the county's report. The local construction market data guide lists the permit and housing counts that cover smaller work.
