About Monterey County

Monterey County, known for its breathtaking coastline and rich agricultural land, is also becoming a beacon for modern housing solutions, particularly through the integration of Accessory Dwelling Units (ADUs). These compact, efficient homes are a smart choice for homeowners looking to add value to their property or offer comfortable living quarters for family members, guests, or renters.

What are the benefits of having an ADU?

ADUs offer several advantages for homeowners. They can provide additional rental income, accommodate family members, increase property value, and contribute to the community by addressing housing shortages. Moreover, as prefab units are constructed off-site and delivered ready to be installed, they promise a faster, more efficient, and less disruptive building process compared to traditional construction methods.
