Custom Homes

With over 16 years of experience, Ciaran Mackey, the General Contractor and owner of CMAC Construction, has been involved in creating some of the most prestigious homes in San Francisco since he first arrived in America in 2006. During his ten years at O’Neill Construction, he had the privilege of working alongside his fellow Irishmen, who were among the finest carpenters to come out of the Emerald Isle, under his close friend and owner, Patrick O’Neill.

Today, Ciaran and the amazing CMAC team create stunning properties that are as unique and refined as their owners. We build custom homes that reflect the personalities of those who live in them. We bring your vision to life with open communication and a commitment to excellence at every step. Our expertise in luxury residential construction ensures that no detail is overlooked—from custom millwork and spiral staircases to exquisite carpentry and high-end finishes.

Each home we build is thoughtfully designed to match your lifestyle, style, and standards. With CMAC, you can expect a smooth process, a collaborative partnership, and a finished home built with integrity, precision, and lasting quality.
