About YDS Architects
Design that fits the city. Permitting that doesn’t fight it.
Founded by principal architect Yifu Pan, AIA, YDS began with a focus on ADUs and quickly became known for its mastery of LA’s permitting maze. Today, we work with homeowners, developers, and business owners to navigate SB9, SB684, density bonus programs, and the evolving future of urban infill.
Whether it’s a fourplex in South LA, a duplex in Pasadena, or a small-lot subdivision in the Valley, our approach is rooted in clarity, efficiency, and thoughtful design.
