How often should you conduct or update a reserve study?

‍

A reserve study is not a one-off project - in fact, it’s recommended to update them once every three years.

A lot can change in the space of even one year, and keeping your reserve study up to date is very important to make sure finances are on track.

In this guide, we’ll explain why it is recommended to update your rserve study once every three years, and how it varies depending on location and specific circumstances.

The Industry Standard: Annual Update, On-Site Visit Every Three Years

The National Reserve Study Standards published by the Community Associations Institute (CAI) - the framework most reserve professionals, lenders, and state regulators rely on - recommend an annual reserve study update with a full on-site inspection at least once every three years.

That cadence is not arbitrary. Component conditions, replacement costs, and funding assumptions can shift meaningfully in twelve months. 

A reserve study that has not been refreshed or looked at in three years can often be working on very outdated numbers, and one that has not been updated in five years should be treated as a historical document rather than a planning tool.

The Three Levels of Reserve Study

CAI defines three distinct levels of reserve study, and understanding the difference helps boards plan their update cycle correctly.

• Level I - Full Reserve Study. A complete study including a full component inventory, on-site condition assessment, life and valuation estimates, fund status, and a funding plan. Required for first-time studies and when an association undergoes major change - significant new components, large additions, or a substantial restructuring of common areas.
• Level II - Update With Site Visit. A refresh of an existing study based on an on-site inspection. The component inventory and condition assessments are reviewed against current conditions, and the funding plan is recalculated. Most associations should have a Level II study performed every three years.
• Level III - Update Without Site Visit. An annual desk update between Level I or II studies. Financial assumptions, replacement costs, and the funding plan are adjusted using current data and the analyst's judgment, without a new on-site inspection.

A typical, well-run association cycles through Level III updates annually with a Level II update every three years.

State Requirements Vary

Many states now have statutory requirements governing how often a reserve study must be conducted, updated, or disclosed. A few examples:

• Virginia requires associations to review their reserve study at least once every five years.
• California requires a reserve study with on-site visual inspection at least once every three years, with annual review.
• Washington recommends an annual update and review under the Washington Uniform Common Interest Ownership Act.
• Florida introduced Structural Integrity Reserve Study (SIRS) requirements after the Surfside collapse, mandating a SIRS every ten years for condominium buildings three stories or higher, in addition to standard reserve study practices.

Requirements continue to evolve, particularly in coastal and high-density jurisdictions. Our State Law Guide provides a current summary of reserve study legislation across the states we serve.

When to Update Off-Cycle

Even a well-maintained reserve study can be made obsolete by events between scheduled updates. 

An off-cycle update should be considered when any of the following occurs:

• A major component is replaced earlier or later than the study projected.
• Significant inflation, supply-chain disruption, or material cost spikes change replacement cost assumptions.
• New components are added - a new clubhouse, pool, roof system, or shared amenity.
• The association is preparing for a special assessment, loan, or sale-related disclosure.
• A lender, insurer, or potential buyer requests a current reserve study.
• A major weather event, casualty loss, or accelerated wear has affected components.
• A new board or management company wants a current baseline before making funding decisions.

Each of these circumstances changes the math behind the funding plan, and continuing to operate from a stale study introduces avoidable risk.

What Happens When a Reserve Study Goes Out of Date

An out-of-date reserve study quietly becomes a liability. Replacement cost figures lag the market, component conditions diverge from the inventory, and the recommended contribution rate stops reflecting reality. Boards making funding decisions from a stale study often discover the gap only when a major component fails - and the reserves to address it are not there.

What to Do Next

If your association is not sure whether its reserve study is current, the review is straightforward:

1. Check the requirements that apply in your state - see our State Law Guide.
2. Review your most recent reserve study and assess whether the components, costs, and funding plan still reflect reality.
3. Talk to your reserve study provider about the right level of update for your situation.
