If you live in Unincorporated Miami-Dade, can you turn your single-family property into a duplex?

Updated: Mar 27, 2023


Public Housing and Community Development Conference

Yesterday, Public Housing and Community Development along with Miami-Dade County's Planning Department unveiled the regulations on their new Workforce Housing Development Program.

I was one of the speakers and my drawings for the "Expandable House" are on display behind the speakers. In the photo I am in the top right-hand corner. In the second row is Commissioner Barbara Jordan and Michael Liu, the director of Public Housing and Community Development. In the third row is Rosa Davis from the Planning Department and Christine Velazquez from Department of Environmental and Resource Management. These are the people who are working on the regulations for this program.

Even though the program really works well for large development projects of 20 units or more, there are opportunities for many people who want to develop single-family and duplexes for workforce housing. In some cases, a present RU-1 lot can be converted to duplex zoning without a public hearing. The county requires an application and the zoning change will be granted on a case by case basis.

Mr. Michael Liu, the director of Public Housing and Community Development, said we need about 300,000 units of workforce housing in the county. Workforce housing is geared to people who make between 60% and 140% of area median income.


And now with the Biden and the federal government granting additional funding to areas that reduce the amount of single-family zoning, there will be a push to grant more of these zoning adjustments so as to create more duplexes within single-family developments.
