SWFWMD and Sarasota County: How the Regulatory Framework Works

The Southwest Florida Water Management District (SWFWMD) governs water use, irrigation scheduling, stormwater management, and groundwater permitting across a 16-county region — including all of Sarasota County. Every property in Sarasota County from Siesta Key to Englewood to North Port falls under SWFWMD jurisdiction.

Unlike some water management districts that only enforce restrictions during declared drought periods, SWFWMD operates under permanent Year-Round Water Conservation Measures. The twice-per-week schedule is in effect every single day of the year in Sarasota County — regardless of rainfall levels, season, or drought status. The restricted mid-day window (10am–4pm) applies year-round as well.

Sarasota County enforces these rules through a combination of SWFWMD field inspectors, Sarasota County code enforcement, and neighbor complaint mechanisms. For properties in Wellen Park and other CDDs, HOA violation tracks run parallel to SWFWMD enforcement — meaning you can receive both an HOA notice and a county enforcement notice simultaneously for the same irrigation issue.

SWFWMD Watering Schedule — Sarasota County 2026

SWFWMD allows landscape irrigation twice per week year-round. The permitted days are determined by your property's street address number:

SWFWMD Irrigation Day Schedule — Sarasota County 2026

Address TypeWatering DaysAllowed Hours
Odd-numbered addressWednesday & SaturdayBefore 10am or after 4pm
Even-numbered addressThursday & SundayBefore 10am or after 4pm
No address (HOA common areas)Tuesday & FridayBefore 10am or after 4pm
New sod / plants (exemption)Daily for 30 daysAny time during exemption window

Mid-day watering is prohibited year-round — not just during drought

The 10am–4pm window is off-limits every single day in Sarasota County. This is a permanent rule — not a seasonal or drought-triggered restriction. Program your controller start times before 8am so all zones complete before 10am, or after 5pm so evening runs fall safely within the after-4pm window.

SWFWMD Water Shortage Phases — What Changes in Sarasota County

Under normal conditions, Sarasota County operates under Year-Round Conservation Measures (twice per week). SWFWMD can declare Water Shortage Phases that restrict irrigation further:

SWFWMD Water Shortage Phases — Sarasota County

PhaseIrrigation AllowedWhen Declared
Year-Round Measures (Normal)2× per weekAlways in effect as baseline
Phase I — Moderate2× per week (unchanged)Aquifer below average seasonal level
Phase II — Severe1× per weekSignificant aquifer decline
Phase III — Extreme1× per week + hour restrictionsCritical aquifer stress
Phase IV — EmergencyNo irrigation (ban)Aquifer at emergency threshold

Rain Sensor Requirement — FL Statute 373.62 in Sarasota County

Florida Statute 373.62 requires every automatically operated irrigation system in Sarasota County to have a functioning rain sensor or soil moisture sensor that overrides the controller when sufficient rainfall has occurred. This requirement has been in effect since 1991 and applies regardless of when your system was installed.

Sarasota County receives approximately 52–55 inches of annual rainfall — concentrated heavily in June through September. A properly functioning rain sensor means your system stays off during and after those intense summer afternoon storms. Without it, your controller may run on schedule the morning after a 3-inch storm event — wasting water and violating state law.

Rain sensor required when

  • Any new automatic irrigation system is installed
  • Existing controller is replaced
  • A permit is pulled for any system modification
  • Commercial irrigation properties
  • HOA / CDD common area systems

Testing your Sarasota County rain sensor

  • Slowly pour water over the sensor head outdoors
  • Active controller should pause within 60 seconds
  • If system keeps running — sensor is failed or disconnected
  • Coastal properties: check for salt corrosion annually
  • Test before dry season starts each October–November

The 30-Day Establishment Exemption for New Sod in Sarasota County

SWFWMD's twice-per-week rule includes a critical provision for new plantings: newly installed sod, ground covers, trees, and plants qualify for a 30-day daily-watering establishment exemption that permits daily irrigation during the root establishment period — regardless of the address-based schedule.

This is particularly important in Sarasota County because:

  • Sarasota's dry season (October–May) spans the most common landscaping installation window — spring installs during March–May are the highest-risk period for establishment failure without daily watering
  • Floratam St. Augustine — the dominant turf variety in Sarasota — is sensitive to water stress in the first 21 days after sodding
  • New construction activity in Wellen Park and North Port means thousands of new lawns are installed annually in sandy, fast-draining soils that require the full 30-day exemption window
  • HOA/CDD communities may scrutinize daily watering as a potential violation — having documentation protects you from ARC complaints during the exemption period
1

Document installation date precisely

The 30-day window begins on the day of installation — not the contractor's proposal date, permit date, or your move-in date. Keep the sod delivery receipt or contractor completion invoice with the exact installation date and property address.

2

Retain documentation in an accessible location

If cited during the exemption window, Sarasota County code enforcement or SWFWMD will request proof of installation date. A signed contractor invoice specifying the installation date is sufficient. SunWest provides this documentation as part of every sod installation project in Sarasota County.

3

Program the exact end date into your controller

Set a calendar reminder for day 31 to switch the controller back to the address-based twice-per-week schedule. Forgetting to revert is one of the most common post-installation violations in new construction communities like North Port and Wellen Park.

4

Communicate proactively with your HOA ARC

If you're in a Wellen Park, Palmer Ranch, or HOA-governed community, notify your ARC in writing before installing new sod. Include the anticipated installation date and the 30-day exemption end date. This prevents neighbor complaints and demonstrates compliance awareness.

Sarasota County Communities — SWFWMD Compliance Context

Sarasota County encompasses a wide range of residential communities — from brand-new master-planned CDDs to established coastal communities and barrier island properties — each with slightly different compliance contexts layered on top of SWFWMD's baseline rules:

Wellen Park

ARC approval required

The largest active master-planned community in Sarasota County. CDD governance with active ARC oversight. New construction activity is high — many homeowners inherit builder-programmed controllers that need schedule verification. Sandy soils drain fast; establish exemption fully before switching to 2× weekly.

Palmer Ranch

Aging sensor common

Established planned community with multiple HOA sub-communities (Prestancia, Esplanade Golf & CC Sarasota side). ARC documentation required for irrigation modifications. Many systems installed in the 1990s–2000s may have aging rain sensors. Verify sensor function before dry season.

Venice / South Venice

Older controller base

City of Venice has its own municipal utilities but SWFWMD rules apply uniformly. Venice's clay-sandy mixed soils in older neighborhoods behave differently from newer sandy CDD soils. Historical neighborhoods predate modern controller standards — sensor upgrades often needed when retrofitting systems.

Siesta Key

CCCL + HOA compliance

Single Sarasota County permit jurisdiction (simpler than multi-municipality barrier islands). SWFWMD rules apply identically. Higher HOA density in Crescent Beach mid-key zone — ARC requires documentation. Coastal salt air degrades sensor components; marine-grade housings recommended. CCCL applies within ~300 ft of Gulf shoreline.

Nokomis / Osprey / Casey Key

Casey Key: CCCL + strict HOA

Casey Key is a private barrier island with strict HOA governance and CCCL overlay. Nokomis and Osprey are unincorporated Sarasota County — simpler permit path than municipal jurisdictions. Sandy soils throughout require smart ET scheduling to optimize 2× weekly watering efficiency.

Englewood / North Port

Verify builder programming

North Port and unincorporated Englewood are among the highest-growth zones in Sarasota County. Enormous new construction activity means many systems are builder-standard — verify the schedule was programmed correctly for the odd/even address assignment. North Port's flat topography creates drainage challenges that affect optimal irrigation zone timing.

Programming Your Sarasota County Controller for SWFWMD Compliance

Correct controller programming is your primary protection against Sarasota County enforcement notices. Here's the step-by-step:

1

Identify your address type (odd or even)

Your permitted watering days are determined by your street address number — not your lot number, subdivision name, or HOA unit designation. 5523 Wellen Park Blvd is odd (Wednesday/Saturday). 2240 Palmer Ranch Pkwy is even (Thursday/Sunday).

2

Set start times with full-zone buffer

Sarasota County properties typically have 4–7 irrigation zones averaging 10–18 minutes each. Program your first start time no later than 7:30am to guarantee all zones complete before 10am. For evening cycles, start at 5pm or later.

3

Disable all unused controller programs

Controllers have multiple programs (A, B, C). A builder-programmed controller in a new Wellen Park home commonly has Program A set correctly and Program B left on a different schedule from the establishment period. Check and disable all unused programs.

4

Enable seasonal water budget adjustment

Sarasota's rainy season (June–September) delivers 4–7 inches per month. Smart ET controllers automatically reduce runtime by 40–60% during rainy season — often eliminating the need to irrigate entirely in July and August. This compliance-safe reduction is also the most cost-effective programming option.

5

Annual rain sensor test before dry season

Perform a pour-water test on your sensor each October before the dry season begins. Sarasota's coastal and near-coastal properties experience salt air corrosion that shortens sensor lifespan — test annually, replace every 3–5 years regardless of apparent function.

Sarasota County Irrigation Permit Requirements

New irrigation system installations in Sarasota County require a building permit. Permit jurisdiction varies by municipality:

Unincorporated Sarasota County

Sarasota County Development Services — covers Wellen Park, Palmer Ranch, Nokomis, Osprey, Englewood, Casey Key, and most barrier island properties. Permit process typically 2–3 weeks residential.

City of Sarasota

City of Sarasota Building, Zoning & Code Enforcement — separate permit office from county. Handles Historic District properties which have additional design review layers beyond standard permit review.

City of Venice

City of Venice Community Development — Venice has its own municipal permit process. Historical Venice neighborhoods often have unusual lot configurations that require modified irrigation zone layouts.

SWFWMD Violations in Sarasota County — Enforcement and Fines

SWFWMD enforcement in Sarasota County comes through several pathways. Common violation triggers:

  • System watering between 10am and 4pm (most frequent violation)
  • System running on non-assigned days (odd/even mix-up)
  • Non-functioning or bypassed rain sensor confirmed on inspection
  • Exceeding twice per week during declared Phase II shortage conditions
  • Irrigation runoff reaching public right-of-way, sidewalk, or storm drain

First-time residential violations in Sarasota County typically result in a courtesy notice with a correction deadline rather than an immediate fine. Repeat violations, commercial property violations, and violations discovered during active inspections escalate more quickly. Florida Statute 373 allows fines up to $10,000 per day per violation for continuing violations — though residential first-offenses rarely reach this level.
