Your choice of finishes—like kitchen cabinetry, flooring, and siding materials—also shifts the bottom line. We help you navigate these variables to find a setup that fits your property.

Frequently asked in San Jose

What are the disadvantages of ADUs?

While ADUs offer many benefits, potential disadvantages include increased utility costs for your property and potential impacts on existing yard space.

How much does an ADU cost in California?

What are the rules for ADUs in California?

California has state-level ADU laws that streamline approvals and limit local jurisdiction's ability to deny them. These laws often dictate minimum lot sizes, setback requirements, and parking rules. However, specific local ordinances in San Jose may still apply, so it's essential to consult with someone knowledgeable about both state and city regulations. They can clarify how these rules impact your specific property.

Is an ADU allowed in Maryland?

We specialize in helping homeowners in California cities like San Jose understand and implement ADU projects. For Maryland, a different resource would be necessary.

What are the rules for ADU in California?

California's ADU laws generally aim to make it easier to build them, often preempting local restrictions on size and density.
