Arizona HOA reserve study requirements (2026)
No mandated reserve study cycle; resale disclosure of reserve study (if any) required for communities of 50+ units.
Quick facts
What the law actually requires
Arizona does not require HOA or condominium associations to commission a reserve study or maintain a minimum reserve balance. A.R.S. Title 33, Chapter 16 (Planned Communities) and Chapter 9 (Condominiums) authorize boards to adopt budgets that include reserves and to collect assessments accordingly under § 33-1242, but impose no study mandate.
Where Arizona does act is at the point of sale. A.R.S. § 33-1806 requires planned communities with fifty or more lots to provide a resale disclosure within ten days of a pending sale that includes the total amount held in reserves and a copy of the most recent reserve study if any exists. The parallel condominium provision, § 33-1260, requires disclosure of reserve fund amounts in the resale package for condo units.
Because no reserve study is mandated, the statute's reference to the most recent study if any effectively creates a soft incentive: associations that do not conduct studies have nothing to disclose to buyers, which can dampen resale values. Most Arizona reserve professionals and HOA attorneys recommend a 3-5 year study cycle under NRSS standards.

Frequently asked questions — Arizona
Is a reserve study required under Arizona law?
No. Arizona statutes do not require an HOA or condominium association to conduct a reserve study or maintain a minimum reserve fund. Boards are authorized to budget reserves but are not compelled to do so.
What does Arizona require at resale regarding reserves?
For planned communities with 50 or more lots, A.R.S. § 33-1806 requires the association to disclose the total reserve balance and provide a copy of the most recent reserve study, if one exists, within ten days of a pending sale. A.R.S. § 33-1260 requires similar reserve fund disclosures for condominiums.
Does having no reserve study hurt an Arizona HOA at resale?
It can. When a community has no reserve study, there is nothing to provide in the resale disclosure, which can raise buyer and lender concerns. Many lenders financing in Arizona condo communities require reserve documentation as part of project approval.
How often should an Arizona association update its reserve study?
While not legally required, most Arizona HOA attorneys and reserve professionals recommend a full study every 3-5 years with lighter annual reviews, consistent with NRSS best practices and Fannie Mae project approval guidelines.
