Where Integrity Meets Craft
Gerosa Construction Inc. is a boutique residential design-build firm dedicated to bringing each client’s vision to life with transparency, precision, and care.
We take a design-led approach to every remodel, addition, and ADU — ensuring each project is architecturally aligned and meticulously executed. We notice the seams, the seals, the alignment — because the details matter.
By intentionally limiting the number of projects we take on, we provide direct communication, hands-on leadership, and consistent attention from start to finish.

We hired Phil and his team for an ADU for our elderly parents, and time was critical. From our first meeting, Phil showed genuine compassion and promised to complete the project in 8 weeks — and he delivered. His team was skilled, efficient, and even worked Saturdays to meet the deadline. The finished ADU is beautiful, exactly what we envisioned, with impeccable workmanship and attention to detail. I highly recommend Phil and his team for any construction project.
