Littlejohn & Co has acquired Milrose Consultants, a New York-based provider of building lifecycle services including permitting, engineering and architecture consulting. The private equity firm purchased the company from Southfield Capital as demand grows for maintaining aging infrastructure more proactively, according to managing director Brian Michaud.

Milrose delivers specialized services spanning code consulting, municipal compliance and special inspections across the building lifecycle. These offerings address increasing needs as commercial and residential structures require more intensive upkeep and regulatory oversight.

The acquisition reflects broader market trends where private equity firms are targeting niche service providers that benefit from long-term infrastructure maintenance cycles. Building owners face mounting pressure to meet updated safety codes and compliance standards.

Littlejohn's move positions the firm to capture growing demand for specialized building services as infrastructure ages nationwide. The deal illustrates how private equity views building lifecycle consulting as a defensive play in uncertain economic conditions.
