2026 San Antonio Watering Rules & Lawn Care Calendar

Last updated: July 5, 2026

San Antonio is in SAWS Stage 3, and after years of drought drawing down the Edwards Aquifer, these are the tightest rules most homeowners here have ever gardened under. Sprinklers run one day a week, in two narrow windows, and violations now show up as a charge on your water bill instead of a court date. Whether your yard is in Alamo Heights, Stone Oak, Monte Vista, or out toward Helotes, here is exactly what Stage 3 allows in 2026 and how to keep a South Texas lawn presentable on it.

Your Stage 3 watering schedule

• Irrigation systems, sprinklers, and soaker hoses: once a week, only on your designated watering day, and only from 5 to 10 a.m. or 9 p.m. to midnight.
• Drip irrigation and tree bubbler zones: Mondays and Fridays, same hours.
• Hand-held hose: any time, any day. This is the tool that keeps trees, beds, and stressed spots alive between legal waterings.
• Vegetable gardens: drip three days a week, Monday, Wednesday, and Friday, during watering hours.

Your designated day is set by your street address; look yours up at saws.org and program the controller to match. Areas without an address, like medians and neighborhood entryways, water on Wednesday.

What a violation costs now

SAWS moved enforcement onto the bill. A documented violation brings a non-compliance charge, 137 dollars the first time for a typical home, and it climbs for repeats. The first one can be waived by taking a one-hour online course. Separately, heavy outdoor use gets expensive in Stage 3: single-family accounts pay a surcharge of 10.37 dollars per thousand gallons on use above 20,000 gallons a month. Water waste, including runoff and overspray onto pavement, is prohibited at all times, and washing driveways or sidewalks is banned outright.

New sod, seed, and plantings

One legal watering a week will not establish new sod in a San Antonio summer. Hand watering any day covers small plantings, and SAWS offers a variance process for new landscapes that genuinely need more. If you are planning an install, apply for the variance first and aim for fall, when establishment takes a fraction of the water.

2026 San Antonio lawn care calendar

Most lawns here are Bermuda, zoysia, or St. Augustine, and the calendar follows the heat.

• Spring (Mar to May): green-up. Take a clean first cut, apply pre-emergent early, fertilize only after full green-up, and have the irrigation system checked before summer, including a run-time tune so one weekly cycle actually soaks.
• Summer (Jun to Aug): survival season. Mow high to shade roots, water deep in the pre-dawn window on your day, use the hand hose on hot spots and young trees, and expect some browning; a drought-stressed lawn that recovers beats a fined one.
• Fall (Sep to Nov): the rebuild. Fertilize to restore roots, aerate compacted ground, patch thin areas, and do your planting and design work now.
• Winter (Dec to Feb): mostly dormant. Cut watering to occasional deep soaks, prune, and plan any renovation you want green by May.

A yard built for Stage 3

Cycle-and-soak is essential in our shallow, rocky soils: split each zone’s weekly run into two or three shorter cycles so water goes down instead of downhill. Move beds to drip so they ride the twice-a-week track instead of the once-a-week one. And converting the most stubborn turf to native and adapted planting takes it off the schedule entirely; SAWS WaterSaver coupons and rebates regularly offset part of that work.

The bottom line for 2026

One day, two windows, drip on Monday and Friday, hand hose whenever. Know your day, keep water off the pavement, lean on fall for anything new, and design the thirstiest corners out of the yard. Stage 3 only lifts after the aquifer holds above its trigger for 15 days, so plan on these rules for a while.

If you would like help tuning a controller to Stage 3, adding drip, or planning a lower-water landscape, the San Antonio Pro Landscape Team works with these exact rules every day.

Rules current as of July 2026. Drought stages move with the Edwards Aquifer; confirm the active stage at saws.org before relying on this schedule.
