Arizona HOA boards can cut common-area water use by converting non-functional turf, switching to drip irrigation, installing smart irrigation controllers, and choosing low-water, desert-adapted plants. With Colorado River shortages and Active Management Area rules shaping supply, conservation also controls costs. Transcend helps Maricopa and Pinal County boards plan landscape projects, compare vendors, and look into city rebate programs.
Why water conservation matters for Arizona HOAs
Arizona’s growth depends on careful water management. Much of central Arizona falls within the Phoenix and Pinal Active Management Areas (AMAs), where the state regulates groundwater use under the 1980 Groundwater Management Act. At the same time, reduced Colorado River deliveries under shortage declarations in recent years have affected Central Arizona Project supplies that many cities and farms depend on. For HOAs, that context shows up as rising water rates, city conservation requirements, and growing owner interest in greener budgets and lower bills.
Common-area irrigation is often one of an association’s largest utility costs, which makes landscape efficiency one of the most practical ways to protect the HOA budget.
Where HOA water goes and what to change
| Area | Common issue | Conservation step |
|---|---|---|
| Turf in streetscapes and medians | Grass that nobody uses, watered by spray heads | Convert non-functional turf to desert landscaping |
| Parks and play fields | Overwatering and runoff onto sidewalks | Keep functional turf; tune heads, schedules, and soil |
| Shrub and tree beds | Spray irrigation and leaks | Convert to drip; add pressure regulation and filters |
| Controllers | Fixed schedules year-round | Smart, weather-based controllers with seasonal adjustment |
| Flood irrigation areas | Shared schedules and berm maintenance | Coordinate with the water provider and maintain berms and gates |
| Water features | Evaporation and leaks | Evaluate whether features still serve the community |
Turf conversion and rebates
Some Arizona cities and water providers offer rebates or incentive programs for removing grass, upgrading irrigation, or installing smart controllers. Program availability, eligibility, and amounts change frequently, and many require pre-approval before any work begins. Check with your city’s water conservation office before signing a contract. The Arizona Municipal Water Users Association, a regional organization of Phoenix-area water providers, also publishes landscape and plant resources that boards and vendors can use.
Remember that some turf is functional. Play fields and parks are amenities owners value, so focus first on grass that serves no recreational purpose.
Build a low-water plant palette
Desert-adapted plants use far less water once established and handle heat better than many non-native species. Work with your landscape vendor or a designer to choose plants from your city’s or water provider’s low-water plant lists. Consider:
- Native and desert-adapted shade trees placed to shade sidewalks and play areas
- Flowering shrubs and groundcovers that tolerate full sun and reflected heat
- Agaves, yuccas, and cacti placed away from walkways and play areas
- Decomposed granite and rock mulch to reduce evaporation and weeds
- Hydrozoning, grouping plants with similar water needs on the same valve
Arizona law and owner landscaping
Arizona law limits an HOA’s ability to prohibit drought-tolerant or low-water-use landscaping on owners’ lots, while generally allowing reasonable design standards. Review your design guidelines so they encourage, not block, xeriscape. Our homeowner guide on desert landscaping and xeriscape and the HOA rules and amendments guide can help you update guidelines.

Water conservation project checklist
- Pull 12 to 24 months of water bills by meter to set a baseline.
- Walk the property with the landscape vendor and map turf, spray zones, and leaks.
- Identify functional versus non-functional turf.
- Check city rebate programs and pre-approval rules.
- Get bids for design and installation using a clear scope.
- Phase work for cooler months to improve plant establishment.
- Communicate the plan, timeline, and expected savings to owners.
- Track water use monthly after completion and adjust controllers seasonally.
Getting owners on board with landscape changes
Owners notice when the grass in front of the entrance disappears. Projects go more smoothly when the board explains the reasons before work starts. Share the water-use baseline, the expected savings, any rebate the association is pursuing, and renderings or photos of similar desert landscapes. Phase the most visible areas thoughtfully, and invite feedback on plant choices at an open meeting. Afterward, report actual water savings so owners see the results. Tips for announcements are in our board communication with homeowners guide.
Also confirm that the project follows your design guidelines and any city requirements for streetscapes, sight lines at intersections, and retention basin function, since changing grades or plant density can affect drainage during monsoon storms.
How Transcend helps
Transcend helps boards analyze water costs in monthly financials, use Predictive Insights to review budget and accounting trends, gather vendor bids, manage landscape projects, and communicate changes to residents. Architectural requests for owner landscape changes are handled through our architectural review management process. Explore maintenance and vendor management or request a proposal.
Frequently asked questions
Usually yes, if the board has authority under your documents to maintain and modify common areas. Large changes to amenities may require owner input or a vote, so check your documents first.
Some cities and water providers offer programs for HOAs and other customers, but terms change often and many require approval before work starts. Contact your city’s water conservation office.
It is a controller that adjusts watering based on weather data or soil moisture instead of a fixed schedule. It helps prevent overwatering during cooler months and after rain.
Arizona law limits an association’s ability to prohibit drought-tolerant landscaping, though reasonable design standards may apply. Ask counsel to review your guidelines.
