Ziese Architecture specializes in adaptive reuse, existing building repositioning, and complex permitting work throughout Los Angeles and California. For over two decades, the firm has navigated the entitlement machinery, code pathways, and regulatory frameworks that make existing buildings difficult — and that most architecture firms avoid. We take on the projects that require deep knowledge of change of occupancy, seismic retrofit, historic review, CEQA, and LADBS plan check. That’s not a side practice. It’s what we’ve built the firm around.The firm also practices residential architecture — custom homes, high-end remodels, ADUs, and fire rebuilds — at the same level of care and technical precision.Principal Architect Daniel Ziese graduated from the University of Arizona with a Bachelor of Architecture in 2002 and began his career in professional practice that same year. In 2008, he established an independent practice in Orange County. In 2011, he incorporated Ziese Architecture, Inc. and relocated the firm to Los Angeles. 200+ completed projects.
