Landscaping Rules in Glendale, AZ

If you live in Glendale or are thinking about moving there, landscaping rules are one of those things you probably won't think about until they affect you directly. Glendale has 6 specific rules on the books covering different aspects of landscaping rules, and some of them might surprise you.

Tree Trimming

Glendale requires owners of trees overhanging a street or right-of-way to prune them so they don't block intersection sightlines or the sidewalk, and lets the Administrator prune or remove hazardous limbs at the owner's expense if they don't.

Key details: Governing section: § 19-99. Owner duty: Prune overhanging branches blocking view. City self-help: Prune/remove at owner expense after notice. Cost recovery: Lien on property until paid. Criminal penalty: Class one misdemeanor, § 19-100.

Section 19-100 makes any violation of this article a misdemeanor, punishable upon conviction by a fine and/or imprisonment up to the maximum set for class one misdemeanors under Title 13 of the Arizona Revised Statutes; unpaid City pruning or removal costs under Section 19-99 also attach as a property lien.

Weed Ordinances

Glendale caps grass and weeds at six inches on every property, occupied or not, and separately bars weeds in sidewalk cracks and curb openings that create a tripping hazard. Desert-landscaped yards get a blight/infestation/hazard standard instead of a strict inch count.

Key details: Governing section: Sec. 25-21(g). Standard weed height limit: 6 inches. Desert landscape standard: Blight/infestation/hazard test. Sidewalk/curb weeds: Banned if a tripping hazard. Repeat offender fine: $100-$1,000 per offense.

A code officer may issue a notice of violation with a cure deadline before citing; missing that deadline brings a citation and possible city-performed abatement billed to the owner plus a 10 percent surcharge, recorded as a lien if unpaid in 30 days. Repeat offenders face a civil fine of $100 to $1,000 for a first offense and $150 to $1,000 for each offense after that within 12 months.

Composting

Glendale generally bans letting garbage or solid waste accumulate on property, but carves out an exception letting residents pile up and store leaves, grass clippings, and similar organic yard waste for composting under rules the solid waste Administrator can set.

Key details: General rule: No accumulation of solid waste on property. Composting exception: Leaves, grass clippings, organic yard waste. Conditions set by: City Solid Waste Administrator. Minimum fine (chapter-wide): $1,000 first offense. Cure period after citation: 24 hours.

Accumulating yard waste or other solid waste outside the composting exemption is a violation of Section 18-9, generally enforced under the chapter's misdemeanor penalty in Section 18-7 (minimum $1,000 fine for a first offense, $2,500 for a subsequent offense). A violator who doesn't remedy the violation within 24 hours of citation can be charged double the commercial bulk trash collection rate.

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

Artificial Turf

Glendale's Unified Development Code bans artificial plant materials from counting toward required landscaping, with one named exception: synthetic turf. Under UDC § 35.4.105, only turf grass substitutes qualify as artificial landscape material, so homeowners and developers may install synthetic turf on private lots, but plastic shrubs, trees or flowers never satisfy any landscape-plan requirement enforced by the Development Services Department.

Key details: Governing section: UDC § 35.4.105(B). Allowed artificial material: Synthetic turf only. Live plant source: Phoenix AMA Low Water Plant List. Maintenance duty: Neat, clean, free of dead plants. Late-correction fine: $1,000 per day after 30-day notice.

Landscaping enforcement runs through Development Services under § 35.4.110. Inspectors who find a landscape-plan violation must serve written notice, and the responsible owner, lessee or HOA has thirty days to correct it. Missing that deadline triggers a civil fine of $1,000 per day for every day the violation continues beyond the thirty-day notice period, collected by the city attorney through a complaint filed in Glendale City Court.

If you are coming from a city with tighter rules, you will find Glendale gives residents more flexibility on artificial turf.

Water Restrictions

Glendale requires all water customers to curtail usage during declared droughts under a City-adopted Drought Management Plan. A first violation brings a written warning and conservation materials, but a second violation adds a fine tied to the drought stage, and a third or later violation doubles the previous fine.

Key details: Policy basis: Curtailment required during declared drought. Governing document: City-adopted Drought Management Plan. First violation: Written notice plus education, no fine. Repeat violations: Fine doubles each subsequent violation. Exemptions: Written request, city manager approval.

A first drought-plan violation brings only a written warning and conservation materials under Section 33-84(a). A second violation adds a fine scaled to the drought stage, and a third or later violation doubles the amount of the previous fine; failing to pay any fine can result in termination of water service, though the customer is entitled to a hearing first under Section 33-84(e).

Compared to other cities, Glendale takes a harder line on water restrictions. The enforcement and penalty structure reflects that.

Tree Removal & Heritage Trees

No one may plant, remove, cut above ground or disturb a tree in a Glendale street right-of-way, park or other public place without first getting a permit from the City's urban forestry administrator.

Key details: Governing section: § 19-97. Permit required for: Plant, remove, cut, or disturb. Covers: City right-of-way, parks, public places. Issuing official: Deputy city manager for public works. Penalty: Class one misdemeanor, § 19-100.

Section 19-100 classifies any violation of the urban forestry article, including removing or cutting a public tree without the Section 19-97 permit, as a misdemeanor, carrying a fine and/or imprisonment up to the maximum set for class one misdemeanors under Title 13 of the Arizona Revised Statutes.

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