The county records describe a proposed 17,117 square foot addition to an existing industrial building. The building is on a 10.94-acre site in Penn Township, Chester County, and is used by Jackson Immuno Research Laboratories, Inc. The county's latest filing is dated March 13, 2026.
The records do not say what the addition would be used for, such as lab space, production or storage. They also do not describe what is on the rest of the site. An addition to an existing building is usually smaller in effect than an all-new development, because the land is already developed.
No township agendas, minutes, news coverage or developer project pages were found that clearly concern this proposal, so nothing is known online about opposition, approvals or timing.
What it could mean nearby
- Any change in traffic, water use or sewage is unknown, because no traffic or utility details were found.
- The addition is small next to the 10.94-acre site, so the site's overall footprint may change only modestly.
- The records do not mention new homes, school effects or the number of jobs.
Where it stands
A land development plan was filed with the county, and its latest filing is dated 2026-03-13. No approval or denial was found. Plans like this usually go through county and township review, and then township approval, before construction permits are issued.
