How San Antonio Handles Landscaping Rules: A Practical Guide

San Antonio maintains 213 local ordinances across all categories, and 7 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where San Antonio falls on the strict-to-permissive spectrum compared to other cities.

Tree Trimming

San Antonio puts the job of keeping trees off the sidewalk squarely on the property owner. Sec. 29-10 requires every occupant, owner or agent to keep trees and shrubs on their premises trimmed so branches don't overhang and block free passage on the adjoining sidewalk or street, and to keep that frontage free of debris.

Key details: Who must trim: Owner, occupant or agent. Standard: No overhang blocking free passage. Debris duty: Keep adjoining sidewalk/street clear. Penalty: Up to $500/day, Sec. 1-5. Related section: Sec. 29-11 covers sidewalk condition.

An owner, occupant or agent who lets trees or shrubs overhang a sidewalk or street, or leaves the adjoining sidewalk and street littered with debris, violates Sec. 29-10 and is subject to the Sec. 1-5 general penalty: a fine of up to five hundred dollars, with each day the obstruction continues treated as a separate offense.

Weed Ordinances

San Antonio bans weeds and grass over 12 inches in height on lots and parcels, treating them as a public nuisance. Code Enforcement can fine the owner and the city will mow the property and place a lien for the cost.

Key details: Height limit: Over 12 inches is a nuisance. Under 3 acres: Entire tract kept clear. Enforced by: Code Enforcement Services (DSD). Nonpayment: City abates, files lien.

Noncompliance is a misdemeanor punishable by fine, and the city mows the lot and assesses the abatement cost as a lien on the property under Section 14-64 for nonpayment.

Rainwater Harvesting

San Antonio actively encourages rainwater harvesting through SAWS (San Antonio Water System) rebate programs. SAWS offers $1.00 per gallon of storage up to $2,000 for residential customers who install at least 500 gallons of cistern capacity. Collected rainwater must be used for non-potable purposes like landscape irrigation. Texas state law (TX Tax Code § 151.355) exempts rainwater harvesting equipment from sales tax.

Key details: SAWS Rebate: $1/gallon of storage, up to $2,000. Minimum Size: 500 gallons of storage to qualify. Use: Non-potable only (landscape watering). State Tax: Equipment exempt from TX sales tax. Workshops: Free quarterly cistern workshops from SAWS.

If you are coming from a city with tighter rules, you will find San Antonio gives residents more flexibility on rainwater harvesting.

Water Restrictions

San Antonio City Code section 34-323 assigns each property a landscape watering day by street address and bars in-ground sprinklers between 11 a.m. and 7 p.m. Under Stage I, irrigation is limited to that one assigned day per week, and the San Antonio Water System issues citations to violators.

Key details: Governing code: City Code § 34-323. Stage I frequency: Once per week by address. Prohibited hours: 11 a.m.–7 p.m. (in-ground). Enforced by: San Antonio Water System. First-violation fine: About $137.

Watering on the wrong day, or running an in-ground sprinkler system between 11 a.m. and 7 p.m., draws a San Antonio Water System citation, with fines starting near $137 and escalating for repeat offenses.

Native Plants

San Antonio promotes native and drought-adapted landscaping as part of its water conservation strategy, enforced through SAWS drought restriction stages. During Stage 1 restrictions (Edwards Aquifer at 660 ft), landscape watering is limited. SAWS encourages xeriscaping with Texas native plants adapted to the region's semi-arid climate. The UDC requires landscaping for new development but does not mandate specific native species.

Key details: SAWS Conservation: Tiered drought restrictions based on aquifer levels. Stage 1 Trigger: Edwards Aquifer at 660 ft mean sea level. Xeriscaping: Encouraged through SAWS programs and rebates. UDC Landscaping: Required for new development per UDC Art. V, Div. 3. Region: Semi-arid; adapted plants reduce water use.

San Antonio is more permissive than most cities when it comes to native plants. That said, there are still limits.

Tree Removal & Heritage Trees

San Antonio requires a tree permit before removing a significant or heritage tree, clearing land, grading, or expanding a building or parking lot past 2,500 square feet. Sec. 35-523(a)(1)(C) lists the regulated activities, and Sec. 35-493(c) fines anyone who starts work without the permit at least $2,000, on top of the mitigation the ordinance requires for what gets removed.

Key details: Permit required for: new construction, land clearing, grading, tree removal. Building-addition trigger: additions over 2,500 sq ft. Minimum unpermitted-work fee: $2,000 under Sec. 35-493(c). Single-family preservation floor: 35% of significant-tree diameter inches. Enforcing agency: City Arborist, Planning & Dev. Services.

Sec. 35-493(a) makes it a violation to intentionally or knowingly remove or destroy a significant or heritage tree, or to perform a regulated activity out of compliance. Sec. 35-493(c) sets a minimum $2,000 fee for anyone who starts work requiring a tree permit before getting one. Standard Article V penalties also apply under Sec. 35-491(c): $25 to $500 per day plus civil penalties up to $1,000, deposited into the tree mitigation fund.

Compared to other cities, San Antonio takes a harder line on tree removal & heritage trees. The enforcement and penalty structure reflects that.

Artificial Turf

San Antonio does not have a specific ordinance prohibiting or regulating artificial turf on residential properties. Given the city's emphasis on water conservation through SAWS, synthetic turf is viewed favorably as an alternative to water-intensive grass lawns. The UDC landscaping standards (Art. V, Div. 3) apply to commercial development and do not specifically address residential artificial turf. HOAs may have their own restrictions.

Key details: City Ordinance: No specific artificial turf regulation. Water Conservation: Synthetic turf viewed favorably by SAWS. UDC: Commercial landscaping standards in Art. V, Div. 3. HOAs: May impose separate restrictions on artificial turf. TX Property Code: § 202.007 limits HOA water-conservation restrictions.

The rules around artificial turf in San Antonio lean permissive, but that does not mean anything goes.

The Bottom Line

Compared to many U.S. cities, San Antonio gives residents more room on landscaping rules. 3 of the 7 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

Keep in mind that San Antonio can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
