Reserve study tips for your Arizona HOA
Costs change. Projects move up or down the priority list. Arizona’s heat takes a toll on outdoor assets. Water use continues to shape landscaping decisions. And sometimes, a component simply wears out sooner than expected.
That’s why your reserve study should not sit on a shelf until the next update. Used well, it can help your board make more informed decisions throughout the year, prepare residents for upcoming projects and address funding needs while you still have options.
Start with what your community needs today
A reserve study is based on assumptions about the condition, useful life and replacement cost of your community’s major assets. Those assumptions are important, but they are not set in stone.Start by comparing the study with what you see around the community.
Are all association-maintained assets included? Have you completed projects since the study was prepared? Has a roof, pool, street or mechanical system needed more repairs than expected? Have recent vendor proposals changed what you expect a future project to cost?
"The reserve study is a great starting point, but it doesn’t always tell the whole story. Your manager and vendors see what’s happening in the community every day. That firsthand knowledge can help the board decide if the plan is still on track or if something needs a closer look."That does not mean changing the plan every time a repair comes up. It means giving your board enough current information to recognize when an assumption may no longer fit.
Megan Donnelly, regional director at FirstService Residential
The Community Associations Institute reserve study standards similarly emphasize that reserve studies should account for changing physical and financial conditions. Regularly reviewing those assumptions can help your board catch potential gaps before they become bigger budget concerns.
Pressure-test your reserve study for Arizona conditions
Where your community is located matters. Arizona’s heat, sun and limited water resources can affect how community assets perform over time, so it is worth checking whether the assumptions in your reserve study still match what you are seeing on the ground.Irrigation is a good example. The City of Phoenix’s HOA Water Efficiency program notes that irrigation systems can become less efficient as they age, and leaks or other problems are not always easy to spot. The Arizona Department of Water Resources also provides water-efficiency resources for HOAs across the state.
If your reserve study includes irrigation controllers, pumps or other major equipment, compare the expected replacement timeline with repair records, water-use data, inspections and input from your landscape professionals. For example, the City of Mesa’s HOA water-management program offers a tool that compares actual water use with recommended levels based on factors such as landscape size, plant types and weather conditions.
Your board does not need to diagnose the system. The goal is to use the information you have to ask better questions. Your reserve specialist, management team and other professionals can help determine whether an issue calls for routine maintenance, a planned upgrade or an adjustment to the reserve study.
Know what Arizona law requires
Arizona does not currently require condominium or planned-community associations to conduct reserve studies or maintain reserves at a specific funding level. Your governing documents may include additional requirements, so boards should review them with qualified Arizona community association counsel.Reserve information does, however, come into play during resale disclosures. Under A.R.S. 33-1260 for condominiums and A.R.S. 33-1806 for planned communities, required resale information includes the association’s reserve balance and the most recent reserve study, if one exists.
The distinction is important. Arizona law may not require your association to conduct a reserve study, but having one can still support thoughtful financial planning and more informed board decisions.
Bring the reserve study into your budget conversations
One of the easiest ways for a reserve study to lose value is to treat it as a separate exercise from the annual budget.Instead, bring the two conversations together.
As you prepare the budget, look at the projects expected over the next several years. Compare the study’s estimated costs with recent proposals and completed projects. Review whether planned reserve contributions still support those needs.
Andi Helms, senior vice president at FirstService Residential, encourages boards to think about those decisions from the homeowner’s perspective, too.
Andi notes,
"Reserve planning is really about giving yourself choices. If you can see a major expense coming and start talking about it early, you have more time to work through the options. That is much easier on the board and on homeowners than trying to solve everything after a project becomes urgent."For each major project on the horizon, consider three questions:
- Does the timing still make sense? Look at the asset’s actual condition, maintenance history and professional recommendations.
- Does the estimated cost still make sense? Compare reserve-study estimates with current proposals, contracts and recent project costs when available.
- Does the funding plan still make sense? Consider whether current contributions and available reserves align with upcoming needs.
Help residents understand what the board is planning
Reserve planning affects residents, even when they never see the reserve study itself.They notice when streets are resurfaced, roofs are replaced, pools close for repairs or landscaping changes. They also notice changes in assessments or other funding decisions.
Clear communication can make those decisions easier to understand.
When a significant project is approaching, explain what needs to be done, why the timing matters and how the board plans to pay for it. If circumstances have changed since the last reserve study, explain that too.
You do not need to overwhelm residents with technical details. A straightforward explanation of what the board knows, what it’s considering and what happens next can go a long way.
Keep the plan useful for the next board
Reserve planning is ongoing, and board members change. Good records help the next group of volunteers understand how previous decisions were made.Document completed projects, updated costs, changes in timing and decisions to defer work. Keep supporting proposals and professional recommendations together. Then make sure those changes are reflected in future budgets and reserve-study updates.
A reserve study cannot make decisions for your board. What it can do is give you a clearer view of what may be ahead.
When you combine that long-term view with current information from your community, your property management team, reserve specialists and trusted vendors, you can make decisions earlier, explain them more clearly and keep your community better prepared for what comes next.
