Hodess Cleanroom Construction

Hodess builds and retrofits controlled environments — ISO-classified cleanrooms, dry rooms, and laboratories — for industries that require particulate, temperature, and humidity control. Typical clients include semiconductor fabs, pharmaceutical manufacturers, biotech labs, and medical device assembly plants. The firm self-performs process piping, HVAC, and cleanroom enclosure systems rather than subcontracting these scope items.

Richard Hodess founded the company in 1974 in Attleboro, Massachusetts, initially serving the early semiconductor manufacturing cluster in the Northeast. The firm remains privately held. Richard Hodess is the namesake founder; current day-to-day leadership is not publicly detailed beyond the founding generation.

Hodess operates as both a design-build specialty contractor and a subcontractor to large general contractors. On many projects, the firm is brought in specifically for the cleanroom package, while a larger GC handles the building shell and site work. The firm self-performs mechanical, process piping, and cleanroom enclosure scopes that are typically subcontracted by generalist builders.

Confirmed end-markets include semiconductor fabrication, pharmaceutical manufacturing, biotechnology and life sciences laboratories, medical device assembly, and aerospace component production. The common thread is any manufacturing process that requires ISO-classified particulate control, precise temperature and humidity management, or vibration isolation.

The firm is headquartered in Attleboro, Massachusetts, but executes projects nationally across the United States. It has delivered over 5,000 cleanroom projects since 1974, indicating a sustained national footprint rather than a regional contractor profile. Specific additional office locations are not publicly identified.

Hodess Cleanroom Construction is an operating business — a specialty construction contractor — not a family office or investment manager. There is no public record of an affiliated investment vehicle, family office entity, or third-party capital management arm. The firm generates revenue through construction and design-build services.

The firm was founded by Richard Hodess and remains privately held. It has not been acquired by a larger engineering or construction conglomerate, which is unusual among specialist cleanroom builders. Many competitors operate as divisions of firms like Exyte, Jacobs, or DPR Construction, while Hodess retains independent specialist ownership (public record).
