How Tempe Handles Landscaping Rules: A Practical Guide

Tempe maintains 119 local ordinances across all categories, and 9 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Tempe falls on the strict-to-permissive spectrum compared to other cities.

Composting

Tempe permits backyard composting and offers free compost bins periodically. City provides curbside organics pickup in a pilot area and runs a Compost Cats partnership. Commercial ops >10 cu yd need ADEQ permit.

Key details: City program: Pilot curbside organics. Setback: 3 ft from property line. Discount bins: Via Public Works events. Drop-off: HHPCC green-waste. Prohibited: Meat, dairy, pet waste.

Nuisance compost pile: $100 civil + 7-day abatement. Unpermitted commercial operation: ADEQ enforcement up to $10,000/day. Contaminated curbside compost bin (wrong items): repeat offense service suspension.

The rules around composting in Tempe lean permissive, but that does not mean anything goes.

Water Restrictions

Tempe encourages water conservation and follows Maricopa County water-use guidelines. While mandatory watering schedules are not always in effect, the city promotes xeriscaping and offers rebates for water-efficient landscaping conversions.

Key details: Approach: Education-based conservation. Xeriscaping: Encouraged with possible rebates. Watering: Avoid midday to reduce evaporation. Drought Response: Mandatory restrictions possible.

During mandatory restriction periods, violators may receive warnings followed by fines. The city's primary approach is education-based, promoting voluntary conservation.

Grass Height Limits

Tempe's property maintenance code requires yards to be kept free of excessive weeds and overgrown vegetation. While there is no specific maximum grass height, properties must be maintained to avoid creating a fire hazard, harboring pests, or detracting from neighborhood appearance.

Key details: Standard: No excessive weeds or overgrown vegetation. Enforcement: Community Enhancement division. Compliance Period: Typically 10–30 days. Abatement: City may clean and bill owner.

Property owners receive a notice of violation with a compliance deadline, typically 10 to 30 days. If not corrected, the city may abate the condition and bill the property owner for costs plus administrative fees.

Tree Trimming

Tempe requires property owners to trim trees that overhang public rights-of-way to maintain clearance for pedestrians and vehicles. Trees on private property must be maintained to prevent hazards. City-owned trees are maintained by the Parks department.

Key details: Sidewalk Clearance: 8 feet minimum. Street Clearance: 14 feet minimum. Responsibility: Property owner for private trees. Public Trees: Maintained by Parks department.

Property owners who fail to maintain required clearances may receive notices from code enforcement. The city may trim overhanging branches at the owner's expense if not corrected within the compliance period.

Tree Removal & Heritage Trees

Tempe does not require a permit to remove trees on private residential property in most cases. However, trees in the public right-of-way are protected and cannot be removed without city authorization. Native desert trees may have additional protections under state law.

Key details: Private Trees: No permit generally required. Public Trees: City authorization required. Native Plants: Protected under ARS 3-904. Saguaro: Special protection under state law.

Unauthorized removal of protected native plants may result in fines under state law. Removing or damaging city trees can result in liability for replacement costs and fines.

Rainwater Harvesting

Arizona encourages rainwater harvesting and Tempe residents may collect rainwater without a permit. No state or local restrictions on residential collection. Arizona offers a tax credit up to $1,000 for qualifying systems. Tempe's monsoon season provides the best collection opportunities. The city supports rainwater harvesting as part of water conservation.

Key details: Permit: Not required for standard residential systems. Tax Credit: Up to 25% of cost, max $1,000. Annual Rainfall: About 8 inches, mostly during monsoons. Types: Rain barrels, cisterns, passive landscape design. Large Systems: Underground cisterns may need building permit.

Standard collection systems carry no violation risks. Systems altering drainage to neighbors may need engineering review.

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

Artificial Turf

Tempe permits artificial turf on residential properties. Arizona law (ARS 33-1817) limits HOA restrictions on water-efficient landscaping. Synthetic turf is popular in Tempe's desert climate as a low-water alternative. Most installations don't require a permit. The city encourages water conservation through its partnership with regional water programs.

Key details: Permitted: Yes, on residential properties. Permit: Not typically required for standard installation. HOA Law: ARS 33-1817 limits HOA restrictions. Heat: Can get very hot in summer, consider shade. Drainage: Proper base and drainage required.

Improperly installed turf causing drainage issues may violate grading requirements. Deteriorated turf may be a property maintenance violation.

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

Native Plants

Tempe encourages native and desert-adapted landscaping. Arizona's Protected Native Plant Law (ARS 3-901) protects saguaro, palo verde, ironwood, and other native species from removal without state permits. Tempe's development standards require desert-adapted plants in new construction landscape plans. The city supports water conservation through xeriscape design.

Key details: State Law: ARS 3-901 (Protected Native Plant Law). Protected Species: Saguaro, palo verde, ironwood, barrel cacti. New Development: Desert-adapted plants required in landscape plans. Xeriscape: Encouraged for water conservation. Removal Penalty: Up to $100,000 for unauthorized native plant removal.

Removing protected native plants without a state permit is a violation with fines up to $100,000. Landscape plans not meeting development standards may delay project approval.

Weed Ordinances

Tempe's property maintenance and nuisance provisions require owners to control weeds and maintain lots. Overgrown vegetation creating fire hazards, harboring vermin, or appearing unsightly is a code violation. The city may abate weedy properties at the owner's expense. Weed growth surges after monsoon and winter rains in the desert climate.

Key details: Standard: Weeds must be controlled, lots maintained. Peak Seasons: Post-monsoon (Aug-Oct), post-winter rain (Feb-Apr). Common Weeds: Tumbleweeds, buffelgrass, broadleaf weeds. Enforcement: Code Compliance responds to complaints. Abatement: City may clear at owner's expense.

Weed violations result in notice, followed by fines and potential city abatement at the owner's expense with possible property lien.

The Bottom Line

Compared to many U.S. cities, Tempe gives residents more room on landscaping rules. 3 of the 9 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.

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