ADUs & Home Additions
Create More Space Without Leaving the Home You Love
As your needs change, your property can change with you. An ADU or home addition can provide valuable extra space while allowing you to stay in the home and neighborhood you already know.
JMF Builders works with San Jose and South Bay homeowners to create additional living spaces designed to complement the existing property and serve a real purpose. Whether you’re considering additional room for family, guests, work, or everyday living, we focus on creating a finished space that feels intentional and connected to the property.
ADUs & Additions
Depending on the project and property, work can involve accessory dwelling units, room additions, expanded living areas, additional bedrooms, additional bathrooms, and other residential expansions.
Because every property and project is different, the exact scope is determined around the homeowner’s goals and the requirements applicable to the project.

- Room additions
