Florida Density Statute

Floridians get their water from rivers, streams, wetlands, lakes, springs, aquifers, and estuaries across the state. Florida rainfall is plentiful, but the challenges facing Florida water contamination have been escalating to new heights.

Flooding, discharge of fats, oils and greases, buildings discharge, overloaded treatment plants, mined limestone quarries, saltwater intrusion, leaking septic tanks and cracked superfund sites, are all contaminants’ problems of their own. When all of them are considered together, we can easily reach a crisis point, where short-term solutions will have a very slim impact.

Potable water conservation is driving the development of new laws, ordinances, and consent decrees in the state of Florida.

Florida Statute 403.892 offers important incentives to developers and home builders for using greywater technologies. The primary aim of the statute is to promote the favorable reuse of water. For this, the state, county, municipality, or special district is required to:

Authorize the use of residential greywater technologies in their corresponding jurisdictions that meet the Florida Building Code requirements and another applicable requirement of the Department of Health for which a homebuilder or developer has satisfied all authorizations or regulatory permits.

Florida Statute 403.892 offers 25 percent density or intensity bonus to a developer or homebuilder if at least 75 percent of a proposed or existing development will have a greywater system installed, or a 35 percent bonus if 100 percent of a proposed or an existing development will have a greywater system installed.

The bonus under this paragraph is in addition to any bonus provided by a county, municipality, or special district ordinance in effect on July 1, 2021.

To apply for the incentives mentioned above, the homebuilder or developer must verify to the respective government agency that all the below requirements are fulfilled.

  • The existing or proposed property has at least 25 separate single-family homes or 25 multifamily residential units, including apartments.
  • Each single-family residence must have its greywater system solely dedicated to its use. Each multifamily unit must be serviced by a system dedicated to its use by a master greywater collection and reuse system.
  • The homebuilder or developer must submit a manufacturer’s warranty or other documents assuring that the residential greywater system will operate as intended and includes approximate potable water savings per system. The submission must come from a government agency, research institute, or building code official.
  • The required maintenance of the greywater system will be the owner’s responsibility.
  • The initial homeowner must supply a maintenance and operation manual for the greywater system. This document will provide the means of contacting the manufacturer or installer and include complete directions to the residential homeowner that the manual shall stay within the residence through the system’s lifespan.
