What Is a Condo Reserve Study — and Does Your MA Association Need One?

A reserve study is a professional assessment of what your association’s shared systems (roof, elevators, boiler, siding, pavement) will cost to repair or replace over the next 20-30 years, and whether your reserve fund is on track to cover it. If your board hasn’t had one done in the last 5 years, you’re budgeting on a guess.

The short answer

A reserve study tells your board two things: what major repairs are coming, and how much money you need saved up before they hit. Skip it, and the association either underfunds reserves and gets hit with a surprise special assessment, or overfunds and sits on cash that should be earning interest or funding smaller improvements now.

What a reserve study includes

A physical inspection of every major shared component — roof, exterior envelope, elevators, HVAC/boiler systems, parking areas, pool or amenity spaces if applicable — with an estimated remaining useful life and replacement cost for each. The study then models your reserve fund’s balance year by year against that spending schedule, and flags the gap (if any) between what you have and what you’ll need.

Why MA associations need one

Massachusetts law (M.G.L. c. 183A, §10(i)) requires every condo association to maintain an “adequate replacement reserve fund” in an account separate from operating funds — but the statute doesn’t define “adequate,” and it does not require a formal reserve study to determine it. That’s left to the board and the trust documents. A reserve study is how a board actually proves adequacy instead of guessing at it.

The real pressure now is coming from mortgage lending, not state law: Fannie Mae and Freddie Mac have tightened reserve-funding requirements for condo loans (see our 2026 condo lending rules update). Associations without adequate, documented reserves risk buyers losing financing, which drags down resale values across the whole building.

How often to update it

Every 3-5 years is the industry-standard interval, or sooner after a major capital project changes your building’s near-term needs. An outdated study is close to useless — costs move, roofs age, and a 10-year-old estimate won’t survive a lender’s underwriting review.

How to read your reserve study

Look at the “percent funded” figure first — it’s your reserve balance divided by what you’d theoretically need if every component were replaced today. Most lenders treat anything under 10% funded as a red flag, and Fannie Mae’s 2026 rule change pushes that bar to 15%. Then check the funding plan: does the study recommend a specific annual reserve contribution, and is your current budget actually hitting that number?

What underfunding leads to (special assessments)

When reserves fall short and a roof or elevator fails anyway, the association has no choice but a special assessment — a lump-sum bill split across every owner, often with little notice. It’s the single biggest driver of owner disputes and delinquencies we see on boards we manage. A properly funded reserve, built off a real study, is what prevents that conversation entirely.

Getting one done

A licensed reserve-study provider does a site walk, reviews your association’s financials and component inventory, and delivers a written report. Cost typically runs $2,500-$10,000 for a Massachusetts association, depending on building size and complexity — a 40-unit townhome community with a few shared elements costs far less than a 300-unit building with elevators and amenities. Green Ocean coordinates this directly for the associations we manage, folding the findings into the annual budget cycle so the board isn’t reacting to a report in isolation.

Frequently asked questions

Is a reserve study required by law in Massachusetts?

No. M.G.L. c. 183A requires associations to maintain an “adequate” reserve fund in a segregated account, but does not require a formal third-party reserve study to determine adequacy. A 2025-26 bill that would have required studies for larger associations has not been enacted. In practice, mortgage lenders are increasingly the ones requiring documented, adequate reserves.

How much does a reserve study cost?

Typically $2,500-$10,000 for a Massachusetts association, depending on size and complexity. Get a quote specific to your building from a licensed reserve-study provider or your property manager.

How often should it be updated?

Every 3-5 years, or after any major capital project that changes your building’s near-term repair needs.

What’s a healthy reserve fund percentage?

Fannie Mae’s 2026 rule change raised its minimum funding threshold to 15% of budgeted assessment income for loan applications dated on or after January 4, 2026. Below that, expect financing friction for buyers and refinancers in your building.
