A homeowners association (HOA) is a legal organization — usually a nonprofit corporation — that owns or manages the shared parts of a community and enforces its rules. If you buy a home in a planned development, a condominium, or many townhome communities, membership isn't optional: it comes with the deed, along with the obligation to pay dues and follow the community's governing documents.
This is a common way to own a home. As of the end of 2025, about 78 million Americans live in roughly 373,000 community associations, according to the Foundation for Community Association Research (verified September 2026).
- An HOA's authority comes from recorded governing documents — chiefly the CC&Rs — that bind every owner in the community.
- A volunteer board of directors, elected by the owners, runs the association and owes the community fiduciary duties.
- Dues fund two budgets: an operating budget for day-to-day expenses and a reserve fund for large, infrequent replacements.
- Before buying into an HOA, read the CC&Rs, the budget, and the reserve study.
Where an HOA's authority comes from
An HOA doesn't invent its powers. They're written in governing documents recorded against every property in the community — chiefly the Covenants, Conditions & Restrictions (CC&Rs), plus articles of incorporation, bylaws, and board-adopted rules. Together these say what the association must maintain, what owners may and may not do, and how the whole arrangement is governed. Our guide to the HOA legal documents every member should review walks through each one.
Day to day, the association is run by a board of directors — volunteer owners elected by their neighbors. Board members owe the community fiduciary duties: they must act in the community's interest, not their own, and within the scope the governing documents allow.
What an HOA actually does
The core job is stewardship of shared property. Depending on the community, that can mean landscaping and a pool, or an entire building's roof, elevators, plumbing, and heating. The association maintains those assets, insures them, hires and manages vendors, enforces the rules, and collects the dues that pay for all of it. Larger associations often hire a professional management company to handle operations, but the board remains responsible for decisions.
Where your dues go
Dues are split between two pots. The operating budget covers predictable, recurring costs — landscaping, utilities, insurance, management. The reserve fund saves for large, infrequent costs: replacing the roof, repaving the lot, rebuilding the pool deck. Operating funds vs. reserve funds covers the split in detail; commonly somewhere between a quarter and a third of dues goes to reserves.
The arithmetic is concrete. Take a 40-unit condominium with dues of $350 a month: that's $350 × 40 × 12 = $168,000 a year. If the budget sends 30% to reserves, the association saves $50,400 a year toward future replacements. Whether that's enough depends entirely on what the community owns — which is what a reserve study exists to answer. When reserves fall short, the gap eventually comes back to owners as a special assessment.
What an HOA can and can't do
An HOA can enforce the recorded rules — architectural standards, rental restrictions, use of common areas — through warnings, fines, and in serious cases legal action. It cannot enforce rules that don't exist in its governing documents, and it must follow its own procedures and state law when it acts. If a rule isn't written down, it isn't enforceable.
Before you buy into one
Three documents tell you most of what you need to know: the CC&Rs (the rules you're agreeing to live under), the annual budget (what dues pay for and whether they're realistic), and the reserve study (whether the community is saving enough, or quietly deferring costs that will land on future owners). A well-run HOA protects property values and spreads big costs fairly across time. A poorly run one shows up as underfunded reserves and surprise assessments — and both are visible in the documents before you buy.
