The Annex Group

The Annex Group (officially The Annex Management Group, LLC) is a U.S. real estate impact housing developer and multifamily real estate firm headquartered in Fishers (Indianapolis), Indiana. The company specializes in the development, construction, acquisition, and management of affordable, workforce, student, and market-rate housing communities across the United States. Its mission emphasizes housing as a catalyst for economic and residential growth, especially in emerging markets and communities with unmet housing demand.

Founded in 2006/2007 (initially operating as Mecca Companies, Inc.), The Annex Group has grown to oversee nearly $1 billion in multifamily and mixed-use projects and has been recognized as a top multifamily developer in industry rankings. The firm’s portfolio includes thousands of units across dozens of states, including developments delivered and under construction in markets such as Indiana, Nebraska, Michigan, Iowa, Kansas, and beyond.

The company pursues a holistic development approach, combining ground-up construction, adaptive reuse, redevelopment, and public-private partnerships—often utilizing affordable housing tax credits and other financial mechanisms—to deliver communities with high resident impact and quality amenities. More recently, The Annex Group has expanded into property management services for its portfolio to enhance resident experience and operational performance.
