Austin's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In Austin, Texas, there are 7 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Tree Trimming

Austin City Code Sec. 6-3-23 requires property owners to trim tree limbs hanging over a sidewalk to a minimum clearance of 14 feet above street level, measured from the nearest curbline, and bars letting a tree obstruct sidewalk use. Ignore a correction notice and the urban forester can trim or remove the tree at the owner's cost.

Key details: Sidewalk clearance: No overgrowth blocking public use. Street clearance height: 14 feet above curbline street level. Correction window: 10 days after notice. City-trim authority: Urban forester, Sec. 6-3-26. Penalty: Class C misdemeanor, up to $100.

Letting a tree drop below the 14-foot street clearance or obstruct a sidewalk is a Class C misdemeanor under Sec. 6-3-8, punishable by up to $100 per offense. If the owner does not clear it within ten days of a Sec. 6-3-25 notice, the urban forester may trim or remove the tree under Sec. 6-3-26 and bill the cost back to the owner.

Rainwater Harvesting

Austin strongly encourages rainwater harvesting and offers rebates up to $5,000 through Austin Water. Texas Property Code §202.007 prevents HOAs from banning rain barrels or cisterns. Building permits are required for cisterns over 5,000 gallons or connected to household plumbing.

Key details: Residential: Up to $5,000 residential rebate. $100/barrel Rebate: $100/barrel rebate, 12 barrel max. Statutory Authority: HOA ban prohibited (TPC §202.007). Statutory Authority: Sales tax exempt (Tax Code §151.355). Permit Cisterns: Permit for cisterns over 5,000 gal.

The rules around rainwater harvesting in Austin lean permissive, but that does not mean anything goes.

Artificial Turf

Austin allows artificial turf in residential and commercial landscapes but it is counted as impervious cover under Chapter 25-2, subject to the 40–45% impervious cover cap. Austin Water does not rebate turf replacement with plastic grass; only live native/adapted landscape qualifies.

Key details: Counts as impervious: Counts as impervious cover. No Austin Water: No Austin Water rebate for artificial turf. Native live plantings: Native live plantings preferred. HOAs can restrict: HOAs can restrict artificial turf. Measurement: 5 ft.

Tree Removal & Heritage Trees

Austin requires a city permit to remove any protected tree measuring 19 inches or more in diameter, and 24-inch heritage oaks, pecans, elms and other listed species get stronger protection with removal barred absent approval.

Key details: Protected tree threshold: 19-inch diameter at 4.5 ft. Heritage tree threshold: 24-inch, 10 listed species. Permit authority: Planning & Development Review / arborist. Heritage removal: Barred without permit. Storm-damage exception: 7 days, imminent hazard.

Removing a protected or heritage tree without a permit is a Land Development Code violation enforced by the City Arborist Program, exposing the owner to stop-work orders, fines, and mandatory replacement-tree mitigation.

This is not one of those rules that cities tend to ignore. Austin actively enforces its tree removal & heritage trees requirements.

Water Restrictions

Austin enforces a mandatory year-round watering schedule under City Code Chapter 6-4. Automatic irrigation systems run just one day per week, assigned by street address, and never between 10 a.m. and 7 p.m. Hose-end sprinklers and drip lines get two days.

Key details: Automatic irrigation: One day per week. Assigned day: Odd Wed, even Thu. Midday ban: No watering 10am-7pm. Drip/hose-end: Two days per week. Penalty: Up to $1,000 per violation.

Austin Water enforces the schedule; watering on the wrong day, during the 10 a.m.-7 p.m. window, or causing runoff draws penalties of up to $1,000 per violation. Report waste by calling 3-1-1.

This is not one of those rules that cities tend to ignore. Austin actively enforces its water restrictions requirements.

Weed Ordinances

Austin caps grass and weeds at 12 inches on private property. Anything taller is an unsanitary-condition violation under City Code Title 10-5, Article 2, and the Austin Code Department can order abatement.

Key details: Height limit: 12 inches maximum. Code section: Title 10-5, Article 2. Enforcement: Austin Code Department. Report via: Austin 3-1-1. Remedy: City abatement, costs billed to owner.

Grass or weeds over 12 inches draw a notice of violation from the Austin Code Department; unresolved overgrowth lets the City mow the lot and bill the owner for abatement costs.

Native Plants

Austin's Grow Green program promotes native and adapted landscaping with a free plant guide and regional nursery partnerships. Texas Property Code §202.007 prohibits HOAs from banning drought-tolerant and native plant landscapes. New developments must meet the Chapter 25-2 native-plant list thresholds.

Key details: Grow Green: Grow Green native plant guide free. Restriction: HOA ban of natives prohibited (TPC §202.007). Age Restriction: Heritage Tree protection at 24" DBH. Protected Species: Protected species list highly specific. Landscape Points: Landscape points favor natives.

If you are coming from a city with tighter rules, you will find Austin gives residents more flexibility on native plants.

The Bottom Line

Austin's landscaping rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Austin is broadly strict or permissive.

These rules come from Austin's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
