The Builder

Signature Development Group

The Signature Development Group (SDG) team has been transforming the Bay Area with exceptional homes and quality communities for more than 30 years. To deliver luxury and excellence, we will endlessly seek new ways to customize residences for the discerning buyer.

SDG knows that connections to existing neighborhoods aren’t a given. Great design doesn’t happen overnight and beautiful architecture doesn’t create itself. Each one is crafted with care and attention to detail. So we explore, push ourselves and redefine. We look at how people live and how life evolves. We incorporate first-rate neighborhood planning and maintain and enhance relationships with surrounding neighbors. And we ensure each residence is timeless, beautiful and distinct.


In every home that SDG builds, we make quality the standard. It’s the creation of an extraordinary product, the scrutinizing and examining of every detail, our preference for only the most durable and high-end materials. We invite you to experience and take it all in, from the architectural design and craftsmanship to the final finishing touches. SDG does more than build homes. We build homes well.

Signature Development Group is privately owned, locally managed and based in Oakland, California. With expertise in residential development, from high-end single-family homes to townhomes, condominiums and mixed-use buildings, the SDG team is one of artisans and experts. We not only listen to the community but also build strong partnerships with cities and municipalities. Founder and President Michael Ghielmetti believes a home is the most significant purchase anyone will ever make, so we envision, shape and create. When it comes to designing and building an SDG home, nothing is overlooked and everything matters.
