An HOA reserve study is a budget planning tool. It lists the major shared components your association has to repair or replace, estimates when each will come due and what it will cost, compares that with the money in your reserve account, and recommends how much to set aside each year. If you have just been handed one, four numbers will tell you most of what you need: the reserve balance, the percent funded, the recommended contribution and the lowest point in the 30-year projection.
Why a reserve study exists
Roofs, paving, paint and pool equipment wear out on a schedule, and replacing them costs more than one year of assessments can cover. A reserve study spreads that cost over the years the component is in use, so the owners who use up a roof help pay for the next one. Some states require a study and many do not. For the wider picture, see our HOA finances section.
The two parts of a reserve study
Community Associations Institute’s Reserve Study Standards divide a study into two parts, and most reports follow that layout.
Physical analysis
This is the component schedule, usually one long table. For each component it shows:
- The inventory: what the association is responsible for, with quantities.
- Condition: what the preparer saw on a visual inspection.
- Useful life and remaining useful life: how long the component normally lasts, and how many years it has left.
- Replacement cost: what the work would cost at today’s prices.
Financial analysis
This part starts with your current reserve balance and reports the fund’s status. It then sets out a funding plan: the contributions going in, the expenses coming out, and the interest and inflation rates the preparer assumed, projected year by year. The standards call for at least 30 years.

Fully funded balance
The fully funded balance is the amount that matches the wear so far. For one component, it is the current replacement cost multiplied by its age and divided by its useful life. As an illustration, a fence that costs $40,000 to replace and lasts 20 years has a fully funded balance of $10,000 when it is five years old. The study adds that figure up across every component.
Percent funded
Percent funded is your actual reserve balance divided by the fully funded balance. If the fully funded balance is $400,000 and the account holds $240,000, the association is 60 percent funded.
It tells you how your savings compare with the wear that has already happened. It does not tell you whether you have the cash for the projects due in the next few years, and it is only as good as the component list and cost estimates behind it. Two associations with the same percentage can be in very different positions if one has a roof due next year and the other does not. The CAI standards say percent funded is not by itself a measure of adequacy, and they do not set a percentage that counts as healthy. Read it alongside the projection.
Recommended contribution
This is the amount the preparer recommends moving into reserves each year, often also shown per home per month. Compare it with what your budget contributes now. Then look at how it changes over time. A plan with steep yearly increases is very different from a level one.
The 30-year projection
The projection is a table or chart with a row for each year: starting balance, contributions, interest, expenses and ending balance. Check four things:
- The lowest ending balance, and the year it falls in.
- The years with the largest expenses, and what they are for.
- Whether the plan assumes assessment increases or special assessments the board has not approved.
- The inflation and interest assumptions.
Small changes in those assumptions move the later years a lot, so trust the near years more than the far ones.
Full, threshold and baseline funding
The recommended contribution depends on the funding goal the plan is built around. The standards describe three:
- Full funding aims to keep reserves at or near 100 percent funded.
- Threshold funding keeps the balance above a chosen dollar amount or percent funded. Depending on where the board sets it, it can be weaker or stronger than full funding.
- Baseline funding only keeps the cash balance from dropping below zero. The standards describe it as carrying the greatest risk and do not recommend it as a long-term plan.
A lower goal means lower contributions today and a higher chance of a special assessment if a component fails early or costs more than expected. Your study should say which goal it uses.
What is and is not a reserve component
The standards use a three-part test. The association must be obligated to maintain or replace the item, the need and timing must be reasonably predictable, and the cost must be material and reasonably estimable. Roofs, paving, exterior paint, fencing, pool equipment and elevators are typical examples.
Routine costs such as landscaping service, utilities and small repairs belong in the operating budget. Items that owners maintain under the governing documents are left out. Check the component list against your governing documents, because a missing component makes every number in the study look better than it is.
How often to update it
A full study includes a site visit, where the preparer builds the inventory and assesses each component. An update with a site visit re-inspects the property using the existing inventory. An update with no site visit refreshes the costs, remaining lives and financial figures. The standards call an update based on a site inspection at least every third year best practice. Your state may set its own schedule. Update sooner after a major project, storm damage or a jump in construction costs.
How to use the reserve study in your budget
- Carry the recommended contribution into the draft budget as its own line. Planning your HOA budget shows where it fits, and our annual HOA budget checklist covers the other steps.
- Look at the projects scheduled for the coming year and get bids. The study’s figures are planning estimates, not quotes.
- If the budget can’t carry the recommended amount, ask the preparer to model alternatives. Don’t quietly budget less.
- Tell the preparer about finished work and changed plans before the next update.
- Show owners what the contribution pays for and when.
When reserves fall short
If the projection runs short, the board has four tools and often combines them:
- Raise regular contributions. This is the gentlest fix when the shortfall is years away.
- Levy a special assessment. It raises money quickly but lands hard on owners. See regular versus special assessments.
- Borrow. A loan spreads the cost over time but adds interest and lender conditions.
- Defer the work. This costs nothing today and often the most later, because damage spreads and safety problems grow.
Your governing documents and state law may limit what the board can do without an owner vote, so talk to the association’s attorney first.
Who prepares a reserve study
A reserve study is normally prepared by an outside provider, called a reserve specialist or reserve analyst. What Is a Reserve Specialist in an HOA? covers the credentials and how to prepare for the site visit. The preparer advises and the board decides. Read the draft, question anything that looks wrong, and adopt the funding plan as a board.
In California
The Davis-Stirling Act sets these requirements:
- Study and inspection every three years. At least once every three years, the board must arrange a visual inspection of the accessible areas of the major components as part of a reserve study. This applies if the current replacement value of the major components is at least half of the association’s gross budget, not counting its reserve account. The board must also review the study every year and make any needed adjustments (Civil Code section 5550).
- Funding plan. The study must include a reserve funding plan showing the date and amount of any change in regular or special assessments needed to fund it, and the board must adopt the plan at an open meeting (section 5560).
- Disclosure to owners. The annual budget report must include a reserve summary showing, among other items, the percent funded and the current deficiency per unit (section 5565). It must come with an Assessment and Reserve Funding Disclosure Summary that states whether projected reserve balances will be sufficient over the next 30 years (section 5570). Section 5570 says its reserve formula does not require the board to fund reserves to that level.
- Balconies and other elevated elements. In condominium buildings with three or more attached multifamily units, a licensed structural engineer, civil engineer or architect must inspect a sample of wood-supported balconies, decks, stairways and walkways more than six feet above the ground at least every nine years. The report must be incorporated into the reserve study (section 5551).
Assembly Bill 2050, signed in September 2026, leaves these requirements in place for now. Starting January 1, 2032, it requires each study to state the minimum contribution needed to keep the projected reserve balance from falling below zero over 30 years, and requires the association to fund reserves at least at that level each year. If the study projects the reserve balance falling below zero within 30 years, the association must also transfer at least 15 percent of its gross annual budget to reserves each year until it no longer does. If the budget cannot cover the minimum, it must levy a reserve funding special assessment, no more than once every nine years, with a member vote if the amount exceeds the limit for board-approved special assessments. Ask your attorney and reserve preparer how to plan for it.
