Permits & Zoning in Palm Beach County

ADU rules vary by zoning district. We verify your property’s eligibility, setbacks, and parking requirements before design. Mesocore provides stamped drawings, structural calcs, to streamline approvals with the City of Palm Beach.

Financing Options for Your ADU

Most homeowners can finance an ADU through traditional lenders such as banks or credit unions — ADUs are treated like any other home improvement or construction project.

To make the process easier, Mesocore also partners with Ocean Capital, our preferred lending partner, who offers financing tailored specifically for ADU projects. Working with a lender familiar with modular construction can streamline approvals and help you access competitive rates.

Whether you choose your own bank or work with Ocean Capital, Mesocore guides you through the financing process so your ADU project stays on track.
