HOA Reserve Study Requirements by State

The information provided in this article is for educational purposes only and should not be construed as legal, financial, or professional advice. Laws, regulations, and industry standards governing HOA reserve studies vary by state and change frequently. Always consult with a qualified attorney, financial advisor, or reserve study professional before making decisions based on the information presented here. HOA Start does not provide legal or financial advisory services.

Reserve study requirements aren’t the same everywhere. 

Some states mandate formal studies on a fixed schedule. Others require a written reserve policy but leave the details to the board. 

And in many states, there’s no statutory requirement at all — just fiduciary duty, lender expectations, and governing documents filling the gap.

HOA reserve studies are nothing new. But after the Florida Surfside condominium collapse in 2021, several states tightened their reserve study and funding rules. More are considering new legislation. What wasn’t required two years ago may be required now — or soon.

No matter where your community is located, it’s important to know the current state of HOA reserve study laws across the country. And once you know what to expect for your specific HOA reserve report study, you’ll be better prepared to take action.

Important note: Statutes change frequently. This guide reflects requirements as of early 2026 and should not be treated as legal advice. Boards should verify current law with legal counsel or their HOA management company before making compliance decisions.

The Big Picture of US HOA Reserve Studies

Most states do not yet mandate reserve studies. But a growing number require either formal studies or documented reserve-fund planning in statute, and several are tightening rules — particularly for condominiums — after recent building-safety events.

Where laws do exist, they generally address one or more of the following:

  • How often a reserve study must be conducted or updated
  • Whether a physical site inspection is required as part of the study
  • How reserve fund status must be disclosed in the annual budget
  • Whether the board must adopt a written reserve or funding policy

 

 

States with explicit reserve study or reserve-planning statutes include California, Colorado, Florida, Hawaii, Maryland, Nevada, Oregon, Virginia, and Washington, among others. 

Several more — including Illinois — are actively considering new legislation.

In most remaining states, reserve studies are recommended but not mandated. That said, governing documents, lender expectations, and fiduciary duty case law may effectively require them even where the statute is silent.

The practical takeaway: even if your state doesn’t mandate a reserve study, your community’s CC&Rs might, your lender probably expects one, and your board’s fiduciary duty all but demands it.

HOA Reserve Study Requirements – At A Glance

State Requirement Level Study Frequency Notes
California Mandatory Every 3 years + annual review Most stringent; requires visual inspection, % funded disclosure
Colorado Statutory reserve planning requirements (HB 22‑1387) Determined by statute and association’s reserve policy Previously required written policy only
Florida Mandatory (condos 3+ stories) SIRS schedule Post-Surfside structural focus; most expansive scope
Hawaii Mandatory Regular cycle Disclosure to owners required
Maryland Mandatory (condos) Not specified Reserve info required in resale certificates
Nevada Mandatory Regular cycle One of few states licensing reserve study professionals
Oregon Mandatory (condos) Annual review Developer must conduct initial study before transition
Virginia Mandatory (condos) 3–5 years + annual review —
Washington Mandatory (condos) Every 3 years + annual review Visual inspection by reserve professional required
Illinois Pending legislation Every 5 years (proposed) Active bill; not yet law
All other states Not mandated — Fiduciary duty, lender expectations, and CC&Rs may still effectively require one

 

States With Significant Requirements

States With Significant Requirements

California

California has among the most stringent reserve study requirements in the country.

Under the Davis-Stirling Common Interest Development Act, associations must conduct a reserve study — including a visual inspection of major components — at least once every three years. The board is required to review and update the study’s assumptions and funding plan every year as part of the annual budget process.

California law also requires detailed reserve disclosures in the annual budget package, including:

  • A summary of current reserve funding level (often expressed as ‘percent funded’)
  • Whether special assessments are anticipated
  • A summary of the reserve funding plan
  • The status of each major common-area component covered by the study

New developments must prepare an initial reserve study early in the life of the association — typically by the end of the first year of operation — so that budgets and assessments reflect long-term capital needs from the outset.

Reserve funds may only be spent on the items they are reserved for. Any withdrawal for other purposes is considered borrowing and must be disclosed to members. Association records, including reserve studies, must be made available for member inspection and copying.

California is effectively a model for what comprehensive reserve study legislation looks like. For a full breakdown, see our detailed guide to [reserve study requirements in California].

Colorado

Colorado’s reserve study requirements have evolved significantly in recent years.

Historically, the Colorado Common Interest Ownership Act (CCIOA) did not explicitly require associations to commission a professional reserve study. 

It did, however, require every association to adopt a written reserve fund and reserve study policy describing if and how studies would be done and how reserves would be funded.

That policy had to address whether the association has a reserve study, whether there is a funding plan tied to it, and whether the study includes both physical and financial analysis. The law allowed studies to be internally prepared.

Recent legislation, such as House Bill 22-1387, strengthens existing law by moving Colorado toward mandatory reserve studies and funding plans for many common‑interest communities, but the exact application and timing can vary. Boards should consult Colorado counsel for current obligations.

This moves the state from “policy required, study optional but strongly implied” toward regular reserve studies and funding plans being required under updated law.

Colorado also requires associations to keep any existing reserve study as part of official records and make it available to owners upon request.

For the full details, see our guide to [reserve study requirements in Colorado].

Florida

Florida overhauled its reserve requirements after the Surfside condominium collapse in 2021. 

Post-Surfside legislation mandates Structural Integrity Reserve Studies (SIRS) for condominium buildings three stories or higher, with dedicated reserves for specific structural components.

SIRS requirements go beyond traditional reserve studies by focusing specifically on structural safety — foundations, load-bearing walls, primary structural members, and other building elements where deferred maintenance poses a safety risk. The scope and cost of these HOA reserve studies are significantly greater than a standard reserve study.

Florida’s changes are the most dramatic example of how building-safety events are reshaping reserve study requirements nationwide. Exact SIRS components, timelines, and exemptions are defined by Florida statute and have been amended multiple times, so boards should rely on Florida counsel or their manager for current specifics.

 

 

Hawaii

Hawaii requires reserve studies for condominium associations under HRS § 514B. 

Studies must be updated on a regular cycle, and associations are required to disclose reserve fund status to owners. The law reflects Hawaii’s recognition that the state’s climate and building environment create particular urgency around long-term maintenance planning.

Nevada

Nevada requires reserve studies for common-interest communities under NRS 116. 

The state also requires reserve study specialists to hold state-issued permits — one of the few states with a specific licensing requirement for reserve professionals. Studies must be updated on a regular cycle and results disclosed to members.

Oregon

Oregon requires condominium associations to conduct an initial reserve study and review it annually under ORS § 94.595. 

The declarant (developer) must conduct the initial study, and the association takes over responsibility for updates after transition. Oregon’s approach emphasizes that reserve planning should begin before homeowners even move in.

Virginia and Washington

Both states require reserve studies for condominium associations, generally with three- to five-year update cycles and annual review requirements. Washington’s law requires that studies include a visual inspection by a reserve study professional.

Maryland

Maryland requires reserve fund disclosures in resale certificates and has specific reserve study requirements for condominium associations under its Condominium Act. Reserve information must be available to prospective buyers during the resale process.

What About States Without HOA Reserve Study Mandates?

What About States Without HOA Reserve Study Mandates?

In states without statutory reserve study requirements, boards sometimes assume a study is optional. That assumption carries risk.

Fiduciary Duty

Board members in every state have a fiduciary duty to manage association finances prudently. 

Courts evaluate whether a board exercised informed judgment when setting budgets and reserve contributions. A professional reserve study is the strongest evidence that the board relied on expert analysis rather than guesswork.

Without a study, a board that underfunds reserves and then levies a large special assessment may face challenges from homeowners arguing the board failed its duty of care.

Governing Document Requirements

Many CC&Rs, bylaws, and declarations include reserve study requirements that go beyond what state law mandates. 

These provisions are contractually binding on the association. Boards should review their governing documents carefully — the obligation to conduct a reserve study may already exist regardless of state statute.

 

 

Lender and Buyer Expectations

Mortgage lenders — particularly for condominiums backed by Fannie Mae or Freddie Mac — increasingly review reserve adequacy when underwriting HOA loans. 

A community without a current reserve study may find that its units are harder to finance, which affects property values across the entire association.

Buyers and their agents also review reserve fund health during due diligence. A community with no study and an undisclosed reserve balance raises red flags — whether or not the state requires disclosure.

The Trend Toward Mandates

Recent legislative activity suggests a trend toward more, not fewer, reserve study and reserve‑fund requirements, especially for condominiums and buildings with significant shared infrastructure.

What to Watch For as HOA Reserve Studies Change

What to Watch For as HOA Reserve Studies Change

Law is always a work in progress, and reserve study requirements will continue to evolve. Some major trends keep an eye on include:

  • Post-Surfside structural focus: Florida’s SIRS requirements are influencing other states considering building-safety legislation. Expect more states to add structural integrity components to their reserve study requirements.
  • New state mandates: States like Illinois have proposed legislation (HB2563, HB0220) that would require reserve studies every five years for associations with significant shared infrastructure. Boards in states without current mandates should track their legislature’s activity.
  • Tighter disclosure rules: Even states that don’t mandate the study itself are increasingly requiring reserve fund disclosures in annual budgets and resale packages.
  • Smaller-community exemptions: Some emerging legislation includes exemptions for very small associations (for example, 15 or fewer units), recognizing that the cost of a professional study may be disproportionate for the smallest communities.

As you can imagine, knowing what to expect and what is required in your state can be overwhelming for association boards. That’s why it’s important to stay informed on any changes or updates to legislation that may affect your community.
