Harmony Design & Development — Kitchen, Bath & ADU Experts in San Francisco, CA
Harmony Design & Development is run by a husband-and-wife team out of the Bayview-adjacent corridor on 3rd Street. Jessica, a San Francisco native with a construction management background, handles client planning and project coordination. Daniel, an electrical engineer by training, oversees technical systems including wiring, solar-ready panel upgrades, and MEP coordination on larger builds. The firm holds license #1071085 and a BuildZoom score of 119, placing it above 99% of licensed California contractors, and carries a 5-star rating on Houzz. The core argument behind how they work is that most SF remodel failures come from communication breakdowns rather than craft failures, and their process is structured accordingly.

Why it’s on home.renovation.reviews
The husband-and-wife model keeps the same two people in contact with a client from first walkthrough through final inspection. Projects do not drift between rotating project managers mid-build — which shows up consistently in their Houzz reviews as the reason clients recommend them without reservation.
