Why Build an ADU in The Bay Area?

Home Office

Given the advantages of technology, it is possible for many professionals to work from home as their primary workplace or as a business. This can be a simple yet comfortable remote workspace or include a separate entrance and parking for a more professional setting.

Low-Cost Apartment for Adult Children

In today’s world becoming independent is more challenging than in years past. An ADU on your property is a great place for adult children to transition to independent lives and families as they build their earning power.

Increased Property Value

Having a well-planned and constructed ADU on your property can result in a very significant enhancement of your property’s value. The space can be used for an office, a family member or as a rental and in any of the cases it is a very attractive feature of the property that increases its utility and value.

In-Law and Granny Accommodations

Be it permanent or temporary, many families enjoy having the ability for a parent or in-law to live with them while having private space for themselves. An ADU is the perfect solution for allowing generations of your family to live together comfortably.

While “good enough” may be good enough for many, the Promodeling team strives for more. We want better, not only for ourselves but for each and every client we work with. We want greatness! That’s why we embrace a full-circle approach to every renovation, remodel or construction project.
