Does El Portal, Florida have zoning, and what does it mean for RVs, lot size and setbacks?

Yes. The Village of El Portal, in Miami-Dade County, adopts its own Zoning and Land Development Code (Chapter 24), which includes a form-based code with Transect Zones Z3-Z5¹. Inside village limits these rules apply, not the county's unincorporated-area zoning code.

In the Zone 4 (Z4) Main Street district, new lots need at least 5,000 square feet and 50 feet of width⁵. Lot coverage is capped at 60% with at least 10% open space⁷. Z4 buildings may be three stories at most⁸. Z4 front setbacks are at least 10 feet, with 0 feet on the sides⁹. Z4 driveways are limited to 12 feet wide at the property line¹⁰.

Older lots can still be built on: the code lets a single-family dwelling go on a nonconforming lot of record in districts where single-family homes are permitted¹. We did not confirm the numbers for other districts, so ask the village which district a parcel is in.

Can you live in an RV or tiny home in El Portal?

Not in an RV. El Portal's code makes it unlawful to live, sleep or cook in a mobile home, motor home, camper or recreational vehicle parked or stored in the village, excluding the mobile home park described in the code². Camping in campers and RVs inside the village is likewise prohibited¹¹. An RV may be stored, unoccupied, in a garage or rear or side yard if it is no more than 9 feet high and 26 feet long, and parking on public streets for more than 24 hours is unlawful².

We could not confirm any village rule on tiny homes or accessory dwelling units; ask the village building official before planning one.

Do you need a building permit in El Portal, and who issues it?

Inside El Portal, the village has its own building official, listed in Miami-Dade County's directory of municipal building officials at 500 NE 87th Street, El Portal, FL 33138, phone 305-795-7880³. Miami-Dade County's building division handles building permits for unincorporated land, and its pages state that incorporated municipalities administer permits within their city limits¹².

Florida's statewide building code applies to residential construction¹³. We could not confirm the village's permit process, fees or owner-builder rules, so call the number above before you start. For the county's owner-builder rules, which apply to unincorporated land, see Miami-Dade County.

How do septic permits work inside El Portal?

Septic permits for El Portal come from the Florida Department of Health in Miami-Dade County, not from the village⁴. Miami-Dade DERM must also review and approve new and total replacement systems, and conventional Type 1 septic systems are not allowed for those¹⁴. Florida requires a site evaluation as part of the septic application¹⁵. Miami-Dade County's NRCS soil rating shows virtually no soils rated not limited for conventional drain fields, so expect an engineered system¹⁶.

We did not confirm whether El Portal requires a sewer connection; ask the village and the Miami-Dade Water and Sewer Department.

Flood rules for building in El Portal

Where base flood elevation data has been provided, a new or substantially improved residential building in a special flood hazard area must have its lowest floor, including any basement, no lower than one foot above the base flood elevation⁶. Enclosed areas below that elevation need flood openings and cannot be finished into rooms⁶. Subdivision proposals must be consistent with the need to minimize flood damage¹⁷.

Building a home in El Portal: the steps, in order

1. Ask the village which zoning district the parcel is in and what it allows¹.
2. Check the flood zone and base flood elevation before design⁶.
3. Call the village building official at 305-795-7880 for the permit application³.
4. Apply for the septic permit with the Florida Department of Health in Miami-Dade County if no sewer is available⁴.

What stays with Miami-Dade County, and what to check before you buy
