Condo reserve study software: what it does and what it costs

Last updated 2026-07-25

What is a reserve study?

A reserve study is a report that inventories a building's major shared components (roof, paving, painting, plumbing risers, elevators, structural elements), estimates their remaining useful life, and projects how much money the association needs to set aside now so it can pay for replacement later without a surprise bill landing on every owner at once. Most reserve studies have two parts: a physical analysis (what components exist, their condition, expected life) and a financial analysis (current reserve balance, funding plan, contribution schedule). Some studies are "full" with an on-site visual inspection; others are "update" studies that revise an older study's numbers without a new site visit. In Florida, condo associations now have a narrower, statutory version of this called a Structural Integrity Reserve Study (SIRS), created by Fla. Stat. 718.112(2)(g) after the 2021 Surfside collapse. A SIRS only covers specific structural components (roof, load-bearing walls, floor, foundation, fireproofing, electrical, plumbing, waterproofing, exterior painting, and pavement) and must be performed by a licensed engineer or architect ^[1]. A general reserve study covering non-structural items (landscaping, pools, signage) can still be done by other qualified preparers, but the SIRS portion has a specific licensing requirement software cannot substitute for. For the full statutory language and a walk-through of what a SIRS has to cover, see our reserve study guide.

What is a reserve study for an HOA?

For a homeowners association, a reserve study works the same way conceptually: inventory shared components, estimate life spans and replacement costs, and build a funding schedule. The difference is legal, not mechanical. Florida's SIRS requirement in Chapter 718 applies to condominiums, not HOAs, so a single-family or townhome HOA is not bound by the same structural inspection statute. That does not mean HOAs are off the hook. Many HOA governing documents (declarations, bylaws) require a reserve study or a reserve funding plan on their own, and lenders (particularly for FHA and Fannie Mae condo/PUD approval) often want to see current reserve documentation before approving financing in a community. An HOA with a pool, clubhouse, gated entry, or shared roofs still faces the same math problem a condo does: big-ticket items wear out on a schedule, and someone has to pay for them. We cover the HOA-specific version of this, including how it differs from the condo SIRS mandate, in hoa reserve study.

What is an HOA assessment (and what is a special assessment)?

An assessment is simply the fee an association charges owners to cover shared costs. Regular assessments are the recurring monthly or quarterly dues that fund operating expenses and reserve contributions. A special assessment is a one-time, extra charge levied when the association needs money it doesn't have on hand, usually because reserves were underfunded, a major repair came up unexpectedly, or a new statutory requirement (like SIRS-driven reserve funding) forces a bigger contribution than the current budget allows. Special assessments are legal in Florida when authorized under the association's declaration and Chapter 718 or 720, and boards typically need a vote or board resolution depending on the amount and the governing documents. They are also the single biggest source of owner anger in condo communities right now, because many buildings deferred reserve funding for decades and are now facing five- and six-figure per-unit bills to catch up. A reserve study, done well and funded consistently, is the tool that prevents special assessments from becoming the default way associations pay for big projects. For a deeper look at how special assessments get triggered and challenged, see hoa special assessment.

How much should an HOA (or condo) have in reserves?

There is no single dollar figure that's "right" for every association; the honest answer is that reserves should match a funding plan built from your specific building's component inventory, not a rule of thumb. That said, funding models generally fall into two camps. Full funding aims to keep the reserve balance at or near 100% of the theoretical value based on each component's remaining life (the percent-funded ratio). Threshold or baseline funding aims to keep the balance high enough to never hit zero, which is cheaper year to year but leaves less cushion if costs run over estimates. Community association research groups have published funding-level studies over the years suggesting many U.S. associations carry reserve balances well below full funding, though there is no single mandatory national benchmark. Florida changed the game for condos specifically. As of the SIRS reforms under Fla. Stat. 718.112(2)(f), most condo associations three stories or higher can no longer waive or reduce reserve funding for the structural components covered by the SIRS once the study is complete; full funding based on the SIRS becomes the default unless the association qualifies for a specific statutory exception ^[1]. That is a meaningful shift from the pre-2022 rules, when owners could vote each year to underfund or waive reserves entirely. If your association is trying to figure out whether it qualifies for any funding relief or delayed timelines, read florida condo reserve fund relief before assuming full funding is mandatory in your case; some associations, especially smaller ones, may have options depending on unit count and building history. Confirm any exception with your association's counsel, because eligibility details are specific and have changed more than once since 2022.

How much does a reserve study cost?

SIRS only (structural components)	Small condo, under 50 units	$8,000 to $15,000
SIRS only	Mid-size, 50 to 150 units	$12,000 to $25,000
SIRS only	Large or high-rise, 150+ units	$20,000 to $40,000+
General reserve study (non-structural)	Any size	$3,000 to $10,000
Combined SIRS + full reserve study	Mid-size	$15,000 to $35,000	These are market-observed ranges, not statutory fees; the Florida Department of Business and Professional Regulation does not set or cap reserve study pricing under its condominium regulatory authority in Fla. Stat. 718.501 [2]. Actual quotes vary by region, engineer availability, and building complexity (waterfront exposure, parking garages, and older concrete structures typically cost more to inspect). Get at least two or three quotes from licensed engineers or architects before committing, and ask what's included: a site visit, photo documentation, and a written funding schedule should all be part of the deliverable, not an add-on. For a line-by-line breakdown of what drives cost up or down, see reserve study for condo association.

Cost depends heavily on building size, number of components, and whether you need a full SIRS, a general reserve study, or both. Rough Florida market ranges, based on typical engineering and reserve-consulting fee structures reported by industry providers, run something like this: | Study type | Typical building size | Approximate cost range |

What does reserve study software actually do?

Reserve study software is a category of tools, some built for professional reserve study firms and engineers, others built for boards and property managers, that handle the financial modeling and record-keeping side of a reserve plan. Typical functions include component inventory tracking (age, life expectancy, replacement cost), funding scenario modeling (full funding vs. threshold funding vs. a custom contribution schedule), multi-year cash flow projections, and report generation formatted for board and owner distribution. Some tools are used primarily by the reserve study professional who prepares your report; you'll never touch them directly, you just receive the PDF. Others are marketed to boards and management companies to track reserve balances between studies, log maintenance history, and flag when a component's estimated life is running out. A few property management platforms (AppFolio, Buildium, and similar systems) include basic reserve tracking modules alongside their broader accounting and communication tools, though these are generally not a substitute for a standalone funding study. What none of these tools do: perform the licensed visual structural inspection that Chapter 718 requires for a SIRS. Software can hold the data, run the projections, and generate the schedule. It cannot put a licensed engineer's eyes on your building's concrete spalling or rebar corrosion. That part of the law is non-negotiable; Fla. Stat. 718.112(2)(g) specifically requires the SIRS to be performed by a licensed engineer or architect ^[1].

Do I need software, or just a good spreadsheet?

Honestly, for a lot of small to mid-size associations, a well-built spreadsheet does 80% of what expensive reserve software does, at zero marginal cost. If your building has 40 or 50 reserve components and one funding plan to track, a spreadsheet with component name, install year, useful life, replacement cost, and a running contribution schedule is entirely workable, and plenty of independent reserve study preparers still deliver their reports as spreadsheets alongside the narrative PDF. Where dedicated software starts to earn its cost is at scale: multiple buildings under one management company, dozens of communities each with their own component schedule, or a board that wants automated alerts when a component's remaining life crosses a threshold. Professional reserve study firms almost always use purpose-built software internally because they're running hundreds of these models and need consistency across reports. For a single condo board handling one building's SIRS and reserve deadlines, the actual bottleneck usually isn't software, it's organization: knowing which deadline applies to your building's age and height, tracking when the milestone inspection and SIRS are due relative to each other, and making sure the board actually schedules the licensed inspection instead of letting it slip. That's a different problem than funding math, and it's the one a lot of boards underestimate. A flat-fee tool like our $199 Building-Specific Board Compliance Kit (see /board-kit-builder) is built for exactly that gap: it organizes your building's specific deadlines, generates owner notices, and tracks what's been scheduled. It does not replace the licensed engineer who performs your SIRS or milestone inspection; it makes sure the board doesn't miss the window to hire one.

What should I look for if I do buy reserve study software?

If your association or management company is evaluating a paid tool, focus on a few practical questions rather than feature lists. First, does it export a report format your reserve study professional and your lender can actually use, ideally a standard PDF with component detail and funding schedule, more than an internal dashboard view. Second, does it let you model multiple funding scenarios (full funding, threshold, and a custom multi-year catch-up plan) so the board can compare options before a vote, since Florida's post-2022 rules limit how much waiving is still allowed for SIRS-covered components ^[1]. Third, check whether it tracks statutory deadlines specific to Florida condos: the milestone inspection timeline under Fla. Stat. 553.899 (25 years from certificate of occupancy for coastal buildings within three miles of the coastline, 30 years for others, then every 10 years after) ^[3], and the SIRS deadline under Fla. Stat. 718.112. General-purpose reserve software built for other states often has no awareness of these Florida-specific triggers, which means the board still has to track them manually anyway. Fourth, ask about data portability. Boards change management companies more often than most software vendors like to admit, and you don't want your 30-year component history locked in a format only one vendor's tool can read.

Are HOA special assessments tax deductible?

Generally, no, not for the owner-occupant of a primary residence. The IRS treats regular and special assessments paid to a homeowners or condo association similarly to other nondeductible personal living expenses, the same category as HOA dues. IRS Publication 530, which covers tax information for homeowners, states that "payments to a homeowners association that are not for the maintenance or repair of a specific area of your property... are generally not deductible" and specifically addresses HOA assessments as generally not deductible for a personal residence ^[4]. There are exceptions. If the unit is a rental property, assessments (including special assessments tied to repairs) are typically deductible as a business expense against rental income, subject to the usual rules distinguishing repairs from capital improvements under IRS guidance on rental expenses in Publication 527 ^[5]. If you use part of your home for a qualifying home office, a portion of the assessment may be deductible proportionally. And in rare cases, a special assessment tied to a federally declared disaster may interact with casualty loss rules, though that's a narrow and fact-specific area. This is genuinely a question for a CPA or tax attorney familiar with your specific situation, not a blanket answer; the IRS guidance is general and your facts (rental vs. primary residence, the nature of the assessment, state-specific rules) change the outcome. Don't rely on an article, including this one, as tax advice.

How does Florida's SIRS deadline interact with reserve study timing?

For most existing Florida condo buildings three stories or more, the SIRS had to be completed by December 31, 2024, per the schedule set out in Fla. Stat. 718.112, with recurring studies required at least every 10 years after that ^[1]. Buildings that missed the original deadline are not exempt; the requirement doesn't go away, and associations that haven't completed a SIRS should treat it as overdue, not optional. The milestone inspection under Fla. Stat. 553.899 runs on a separate but related clock: 25 years from the certificate of occupancy for buildings within three miles of the coastline, 30 years for buildings further inland, and every 10 years after the initial inspection ^[3]. Boards often confuse the two requirements or assume completing one satisfies the other; they don't. The milestone inspection is a structural safety inspection focused on immediate life-safety issues; the SIRS is a funding and component-life study focused on long-term reserve adequacy. You need both, on their own schedules, from licensed professionals qualified for each. Software can help a board see both deadlines on one calendar and track which licensed professional has been engaged for which task. It cannot tell you whether your specific building's governing documents or county require anything beyond the state minimum; that's a question for association counsel, and requirements can vary by county in ways this article can't cover for every jurisdiction. Confirm timing specifics with your association's counsel and your county building department, since local rules and statutory amendments do change.

What's the honest bottom line on reserve study software?

Software is a convenience layer, not a compliance shortcut. It can hold your component inventory, run funding scenarios faster than a spreadsheet, and generate cleaner reports for owner meetings. What it cannot do is replace the licensed engineer or architect Florida law requires for a SIRS, and it cannot make legal judgments about whether your building qualifies for reserve funding relief or an extended deadline. If your board is choosing between spending money on software versus spending it on actually completing an overdue SIRS or milestone inspection, spend it on the inspection first. A board with a perfectly organized spreadsheet and no completed SIRS is still out of compliance. A board with a completed SIRS and a messy spreadsheet has the harder problem solved and an easy one left over. When you're ready to move past spreadsheets, tools built specifically to track Florida's building-specific deadlines (rather than generic reserve math) will save the most board time. That's a narrower and cheaper problem to solve than most people assume.

Frequently asked questions

What is a reserve study?

A reserve study is a report inventorying an association's major shared components, estimating their remaining life and replacement cost, and projecting a funding schedule so owners aren't hit with a surprise bill. Florida condos also face a narrower statutory version, the Structural Integrity Reserve Study (SIRS), required under Fla. Stat. 718.112 and performed only by a licensed engineer or architect.

What is a reserve study for an HOA?

For an HOA, a reserve study works the same way: it inventories shared components (roofs, pools, clubhouses, paving) and builds a funding plan. Florida's SIRS mandate applies to condos under Chapter 718, not HOAs directly, but many HOA governing documents or lenders still require a current reserve study for financing approval.

What is an HOA assessment?

An HOA assessment is a fee the association charges owners to cover shared costs, either regular recurring dues or a one-time special assessment for an unexpected or underfunded expense. Special assessments are legal under Florida's Chapter 718 and 720 frameworks when properly authorized, but they're also the most common source of owner disputes when reserves were underfunded beforehand.

How much should an HOA have in reserves?

There's no universal dollar figure; the right amount depends on your building's specific component inventory and chosen funding model (full funding versus threshold funding). Florida condos three stories or higher generally can no longer waive reserve funding for SIRS-covered structural components once the study is done, per Fla. Stat. 718.112(2)(f), making full funding the default in most cases.

How much does a reserve study cost?

Florida SIRS costs typically run $8,000 to $15,000 for small condos, $12,000 to $25,000 for mid-size buildings, and $20,000 to $40,000+ for large or high-rise buildings, based on market-observed engineering fee ranges. A general non-structural reserve study alone often runs $3,000 to $10,000. Get multiple quotes; the state does not set or cap these fees.

Are HOA special assessments tax deductible?

Generally no, for a primary residence. IRS Publication 530 treats most HOA and condo assessment payments as nondeductible personal expenses. Exceptions can apply for rental properties (see IRS Publication 527), qualifying home office use, or certain disaster-related casualty situations. Talk to a CPA about your specific facts before assuming either way.

Does reserve study software replace the need for a licensed engineer?

No. Software can model funding scenarios and organize component data, but Florida law requires the SIRS itself to be performed by a licensed engineer or architect under Fla. Stat. 718.112(2)(g). No software tool can perform the physical structural inspection or sign the report; that's a licensing requirement, not a data problem.

What's the difference between a SIRS and a milestone inspection?

A SIRS is a reserve funding study focused on structural component life expectancy and cost, required under Fla. Stat. 718.112. A milestone inspection is a life-safety structural inspection required under Fla. Stat. 553.899 at 25 years (coastal) or 30 years (inland) from the certificate of occupancy, then every 10 years. They run on separate schedules and need separate licensed professionals.

Can a condo association still waive or reduce reserves in Florida?

For SIRS-covered structural components, most condo associations three stories or higher can no longer vote to waive or reduce reserve funding once the SIRS is complete, under the post-2022 amendments to Fla. Stat. 718.112(2)(f). Some limited exceptions exist depending on building specifics; confirm eligibility with your association's counsel rather than assuming.

Is a spreadsheet good enough instead of reserve study software?

For many small to mid-size associations, yes. A spreadsheet tracking component age, life expectancy, and replacement cost handles most of the funding math a paid software tool would. Dedicated software earns its cost mainly at scale, across many buildings or communities, or when a board wants automated deadline alerts.

How often does a SIRS need to be updated?

Under Fla. Stat. 718.112, the SIRS must be updated at least every 10 years for condo associations subject to the requirement, following the initial study most buildings had to complete by December 31, 2024. Buildings that missed that original deadline still owe the study; it doesn't expire as a requirement.

Does the SIRS deadline apply to HOAs too?

No, the SIRS requirement under Fla. Stat. 718.112 applies specifically to condominium associations regulated under Chapter 718, not homeowners associations under Chapter 720. HOAs may still face reserve study requirements through their own governing documents or lender requirements, but not this specific state statute.
