Port St. Lucie Setbacks & Height Limits — Residential Zones

Last updated: Verified:

Fact-checked against the current Port St. Lucie Zoning Code and Florida Statutes on September 20, 2026.

Port St. Lucie's residential dimensional standards are in Chapter 158 of the Code of Ordinances. The exact lot size, setbacks, height, coverage, and accessory-use rules depend on the zoning district.

Common Single-Family Districts

Current Chapter 158 provides the following principal single-family standards:

Zone Minimum Lot Front Yard Side Yard Rear Yard Max. Height
RE / Estate Residential (§158.071) 20,000 sq ft; 100-ft width 25 ft 10 ft each 25 ft 35 ft
RS-1 (§158.072) Check current §158.072 lot standard 25 ft 10 ft each 25 ft 35 ft
RS-2 (§158.073) 10,000 sq ft; 60-ft width 25 ft 10 ft each 25 ft 35 ft
RS-3 (§158.076) 7,500 sq ft; 60-ft width 25 ft 7.5 ft each 25 ft 35 ft

The previous page incorrectly cited §158.070 for the Estate Residential district. The current Estate Residential district provisions are in §158.071.

These are base district standards. Chapter 158 contains additional provisions that can affect corner lots, accessory uses, water-related conditions, and other site situations.

Minimum Living Area

For RS-2 and RS-3, current Chapter 158 includes minimum dwelling-area requirements in addition to the yard and height standards. Those requirements should be checked directly when evaluating a new house or replacement house.

Accessory Structures

Accessory uses are governed by additional provisions, including §158.217. Do not assume that every garage, shed, pool enclosure, or other accessory structure follows the principal-building setbacks shown above.

Florida ADU Law Does Not Override Local Zoning

The previous page incorrectly stated that Florida Statutes §163.31771 requires Port St. Lucie to allow ADUs in single-family zones and can override local setback or size minimums.

The current statute is permissive: it says a local government may adopt an ordinance allowing accessory dwelling units in areas zoned for single-family residential use. It does not itself create a statewide by-right ADU entitlement or erase Port St. Lucie's local dimensional standards.

For local ADU eligibility, use the Port St. Lucie ADU rules page and the current local code.

Current-Code Caveat

Port St. Lucie's Municode publication notes adopted ordinances that may not yet be fully codified. For any project, check the current online code and the “Adopted Ordinances Not Yet Codified” list.

That is especially important when relying on a saved copy of Chapter 158.

How to Check a Property

  1. Confirm the parcel's current zoning district.
  2. Read the corresponding Chapter 158 district section.
  3. Check general provisions and accessory-use rules in addition to the base district table.
  4. Review adopted ordinances not yet codified.
  5. Check flood, airport, plat, easement, HOA/deed-restriction, and other applicable conditions.
  6. Confirm unusual conditions with Port St. Lucie Planning & Zoning before relying on a design dimension.

Does Port St. Lucie have special wind or hurricane construction rules?
Yes. Port St. Lucie follows the Florida Building Code, 8th Edition (2023), which imposes strict wind-load design requirements along the Treasure Coast. While Port St. Lucie is outside the High Velocity Hurricane Zone (HVHZ — limited to Miami-Dade and Broward), it sits in a high-wind region where roofs, openings, and structural connections must meet elevated wind-speed standards. Confirm site-specific wind design criteria with the Building Department.
