Horizon West Lawn Watering: One Day a Week Until March

By Nelson Cruz, P.A. | November 8, 2026

A Horizon West home can run its sprinklers one day a week right now. Orange County’s watering schedule switched to the Eastern Standard Time rule on November 1, 2026 and holds through March 13, 2027: odd-numbered addresses water Saturday, even-numbered addresses water Sunday, and nothing runs between 10 a.m. and 4 p.m. Horizon West sits in unincorporated Orange County, so the county ordinance governs rather than a city code, and the single biggest thing that changes the answer is whether the house irrigates with reclaimed water.

Why the county ordinance is the one that applies here

Orange County’s own planning page describes Horizon West as five mixed-use villages and a Town Center in southwest Orange County, roughly 20,704 gross acres, and identifies the area as unincorporated. That status decides which rulebook a homeowner follows. Section 37-602(a) of the Orange County Code applies the county’s water conservation rules throughout all of Orange County except in municipalities that have adopted their own landscape irrigation ordinance. Horizon West is not inside a municipality, so Chapter 37, Article XVIII applies directly. Underneath it, the St. Johns River Water Management District sets the same schedule in Rule 40C-2.042(2), Florida Administrative Code.

Section 37-602(b) then closes the obvious loophole. The schedule applies to landscape irrigation regardless of whether the water comes from ground or surface water, from a private well or pump, or from a public or private utility. Drilling a well does not buy extra watering days.

Your house number sets your day

Section 37-603(a) defines the terms more precisely than most owners expect. The address is the house number of the physical location, excluding post office box numbers. An even-numbered address ends in 0, 2, 4, 6, 8 or the letters A through M. An odd-numbered address ends in 1, 3, 5, 7, 9 or the letters N through Z. If the house number ends in a letter rather than a digit, that letter is what decides the day.

Section 37-603(e) and (f) tie those windows to the federal Uniform Time Act of 1966, so the dates move with the time change rather than with the calendar year. Section 37-604 adds two caps that apply on every permitted day: no more than three-fourths of an inch of water per irrigation zone, and no more than one hour per zone.

What three-fourths of an inch actually is

Three-fourths of an inch over 1,000 square feet of turf is 62.5 cubic feet, or about 468 gallons. Over a 5,000-square-foot irrigated area that is roughly 2,338 gallons in a single watering day, and about 9,351 gallons across four watering days. That matters because Orange County Utilities bills residential water in rising tiers set on total monthly consumption: $1.47 per 1,000 gallons for the first 3,000, $2.04 from 4,000 to 10,000, $4.06 from 11,000 to 20,000, $8.11 from 21,000 to 30,000, and $16.17 at 31,000 and above, effective October 1, 2026. Irrigation stacks on top of indoor use, so it pushes the whole bill up a tier rather than being priced on its own.

Reclaimed water is the exception that changes the schedule

Section 37-608(a)(1) excepts reclaimed water entirely: irrigation from a reclaimed water system is allowed anytime. A home on reclaimed in Horizon West is not limited to Saturday or Sunday and is not bound by the 10 a.m. to 4 p.m. blackout. The county’s reclaimed water rates are also far lower than potable, at $0.30 per 1,000 gallons for the first 4,000, $1.34 from 5,000 to 12,000, and $2.28 at 13,000 and above for meters under one inch, plus a $3.55 fixed monthly charge on a 5/8-inch by 3/4-inch meter.

Reclaimed service carries its own conditions. Orange County’s Reclaimed Water Program Customer Guide states that the county prohibits the use of drinking water for irrigation when reclaimed water service is available, and that new developments near the county system must use reclaimed water for irrigation if their development approvals require it. The same guide requires a county-approved backflow prevention device on the drinking water system before reclaimed service begins, prohibits spigots on the residential reclaimed system, and requires in-ground sprinklers rather than hoses.

The well question has a firm answer on both layers. Rule 40C-2.042(2)(a)4. withdraws the general permit for a private irrigation well once reclaimed water is available, and deems reclaimed available when a utility provides it through a point of connection. The county’s customer guide requires an existing irrigation well to be permanently disconnected from the irrigation system once reclaimed service begins, or fitted with a county-approved double check backflow prevention device. Confirm what serves a specific address with Orange County Utilities at 407-836-5515 before assuming either way, and check the provider itself using our guide to Orange County water service before buying.

New sod gets 60 days, and you have to claim them

Section 37-608(a)(3) allows irrigation of new landscaping at any time of day on any day for the initial 30 days after installation, then every other day for the next 30 days, 60 days in total, limited to the amount necessary for establishment and permitted only on the specific areas where the new landscaping sits. The district rule adds a threshold the ordinance leaves out: under Rule 40C-2.042(2)(a)3.b., an entire irrigation zone qualifies only if new plantings make up at least half of that zone. Below half, only the new plantings may be watered.

The step most owners miss is procedural. Orange County Utilities asks residents to supply a name, phone number, address and sod or landscape receipts to avoid a watering violation during the establishment window. The exception does not waive the rates. For the bill that follows, the county’s Resolution No. 2025-M-19, effective October 1, 2025, allows residential customers who see unusually high water or reclaimed water usage with a matching bill spike to be considered for a billing adjustment, requested on the Residential Lawn Replacement Adjustment Request Form within 60 days of the date of the unusually high consumption.

The other exceptions worth knowing

• Micro-irrigation anytime. Section 37-608(a)(5) allows micro-spray, micro-jet, drip and bubbler systems on any day.
• Hand-held hose anytime. Section 37-608(a)(7) allows a hand-held hose fitted with an automatic shut-off nozzle. Section 37-606(c) makes that nozzle mandatory on any hose used for landscape irrigation.
• Testing the system. Section 37-608(a)(6) allows operation for maintenance and repair at up to 20 minutes per hour per zone, and Section 37-604(c) gives seven days to fix broken or misdirected heads and leaks after written notice from county personnel.
• Rain sensor required. Section 37-606(d) requires a functional rain sensor on every automatic system.

The rule that catches narrow Horizon West lots

Section 37-605(a) applies to any irrigation system installed or substantially modified after July 20, 2008, which covers most of what is in the ground across these villages. Each zone may use only one form of application. Turf must sit on separate zones from other plantings. Overhead spray is permitted only for turfgrass and ground cover with a mature height of one foot or less, so trees and shrubs must be watered by micro-irrigation at the base or within the dripline, by hand-held hose, or by watering can. Any landscape area four feet or less in width, turf included, is restricted to micro-irrigation, which is exactly the side-yard strip between two homes on a narrow lot. Section 37-603(s) defines substantial modification broadly: any new zone, or within a six-month period any repair or replacement of equipment serving more than 30 percent of the irrigated area.

Horizon West and Winter Garden are not on the same rules

The City of Winter Garden borders Horizon West to the north and has adopted its own irrigation ordinance, which under Section 37-602(a) takes the county’s rules off the table inside city limits. The day schedule is identical, but three provisions a homeowner actually feels are not.

Both sets of facts come from each government’s own published rules: the county’s from Chapter 37, Article XVIII, and the city’s from its Water Conservation page. If you are weighing the two areas against each other, the full corridor picture is in the Live Move Orlando Horizon West guide.

What a homeowners association can and cannot require

Covenants in these villages govern landscape appearance, but state law sets an outer limit on them. Section 720.3075(4)(b) of the 2026 Florida Statutes provides that association documents, including declarations of covenants, articles of incorporation and bylaws, may not prohibit or be enforced so as to prohibit a property owner from implementing Florida-friendly landscaping as defined in s. 373.185, and may not create any requirement or limitation in conflict with part II of chapter 373 or a rule adopted under it. Rule 40C-2.042 is such a rule. Section 373.185(3)(b) applies the same limit to a deed restriction or covenant, and s. 373.185(3)(c) applies it to a local government ordinance. Section 373.185(1)(b) defines Florida-friendly landscaping as quality landscapes that conserve water, protect the environment, are adaptable to local conditions and are drought tolerant.

That protection is narrower than it sounds. It voids a covenant that would force watering in conflict with the district rule or bar a Florida-friendly design. It does not void ordinary architectural review, and it does not excuse a dead lawn caused by a broken controller. Pull the recorded declaration and the current architectural standards before you close, using our checklist for Florida HOA disclosure documents and the estoppel certificate.

What a violation actually costs

Section 37-611 runs an enforcement track separate from ordinary code enforcement. Because the county treats a watering violation as irreparable, a code enforcement officer is not required to give the owner time to correct it before issuing a notice. The first violation at a given address carries a notice but no civil penalty. Each subsequent violation at that address carries $25, and a violation occurring three years or more after the last one at that address resets to a first violation.

Read that as written: the ordinance counts violations by address, not by owner. A buyer takes the address’s recent history along with the house. Contesting a notice means filing an appeal within 30 days with a $25 filing fee, addressed to the water division manager, and unpaid penalties can be attached to the Orange County Utilities customer account and billed monthly. Section 37-609 allows a variance from the assigned day on a showing of substantial economic, health or other hardship, but no variance can authorize more than one day per week under Eastern Standard Time or two under Daylight Saving Time.

Before your first Saturday or Sunday

1. Read the last character of the house number and set the controller to Saturday for odd or N through Z, Sunday for even or A through M.
2. Call Orange County Utilities at 407-836-5515 and confirm whether the address has reclaimed water service. If it does, the day limits drop away and the rate falls.
3. Program each zone to stop at or before one hour and under three-fourths of an inch, and keep the run outside 10 a.m. to 4 p.m.
4. Confirm the rain sensor works. It is required on every automatic system, not just newer ones.
5. If sod went in during the transaction, send Orange County Utilities the name, phone number, address and receipts so the 60-day establishment window is on record before a door hanger shows up.
6. Check any side-yard strip four feet or narrower. Overhead spray there does not comply.

Frequently asked questions

Does the one-day-a-week rule apply if I have my own irrigation well?

Yes. Section 37-602(b) applies the schedule regardless of whether water comes from ground or surface water, a private well or pump, or a public or private utility. A well changes who bills you, not when you may water. If reclaimed water becomes available, Rule 40C-2.042(2)(a)4. also withdraws the general permit covering that well for landscape irrigation.

My new Horizon West home just got sod. Can I water it every day?

For the first 30 days after installation you may water at any time of day on any day, then every other day for the next 30 days, under Section 37-608(a)(3). The allowance covers only the areas where the new landscaping sits. Give Orange County Utilities your name, phone number, address and receipts so the exception is documented, and note that the water is still billed at normal rates.

Can my HOA fine me for a brown lawn when the county only lets me water once a week?

An association can enforce appearance standards, but Section 720.3075(4)(b), Florida Statutes, voids any association requirement or limitation that conflicts with a rule adopted under part II of chapter 373, and the irrigation schedule in Rule 40C-2.042 is such a rule. The same section bars a covenant from prohibiting Florida-friendly landscaping as defined in s. 373.185. A demand that you water on a day the schedule prohibits is not enforceable. A notice about a lawn you simply stopped maintaining is a different matter, and is worth resolving with the association directly.
