Daniel A. O'Callaghan



Dan guides clients through all stages of the real estate life cycle, from acquisition to development, construction, financing, leasing and sale of multifamily and commercial properties. His practice focuses on transactional real estate, real estate development, land use, property taxation and zoning law.

Individual investors, developers, financial institutions, municipalities and nonprofits rely on Dan for assistance in negotiating complex real estate transactions, obtaining land use approvals and facilitating public-private partnerships.


Municipal governments turn to Dan for guidance on planning and zoning law issues. He has a deep knowledge of urban planning and is a member of the American Institute of Certified Planners (the American Planning Association's professional institute) which certifies professional urban planners.

Prior to attending law school, Dan built his knowledge of real estate matters by working for the Milwaukee Department of City Development. He also served as the Executive Secretary of the City’s Board of Zoning Appeals for more than four years. 


Representative matters include:

  • Assisting with all aspects of a $34 million real estate development project, from planning through entitlements, financing land acquisition and development. The project drew on Dan’s skills in working with multiple stakeholders, a robust public participation process, an advisory referendum, a citizen lawsuit, and multiple development agreements with the local municipality and the State of Wisconsin Department of Transportation.
  • Advising a regional healthcare provider in securing municipal approvals for construction of a 80,000-square-foot outpatient center and medical office building, in a project valued at $28 million.
  • Guiding a real estate development firm in a $98 million project that involved securing tax increment financing for a large-scale redevelopment project on Madison’s Capitol Square.
  • Assisting a Wisconsin liberal arts college with the $38 million redevelopment of a former power generating station into a student activity and recreation center.
  • Supporting a client in the $25 million development of a 71-unit student apartment building near the University of Wisconsin-Madison campus; advised on real estate acquisition, construction financing, municipal permits/approvals, and construction.
  • Assisting a large-scale property owner in the permitting process for transfer of a regulated dam in southeastern Wisconsin.
