HOA engineering report: what it is and what it costs

Last updated 2026-07-24

What is an HOA engineering report?

An HOA engineering report is a written evaluation, prepared and sealed by a licensed engineer (or in some cases an architect), that documents the physical condition of a building's structural components. Think load-bearing walls, foundations, roofs, balconies, waterproofing, and in coastal buildings, things like rebar corrosion in concrete. For Florida condo and HOA boards, this isn't optional paperwork you can skip. Since the 2021 Champlain Towers South collapse in Surfside, Florida law requires specific engineering assessments for buildings over a certain age and height. These reports come in two main flavors: the Milestone Inspection (a structural safety check) and the Structural Integrity Reserve Study, or SIRS (a funding and condition report for reserves). A general 'HOA engineering report' can also mean something narrower, like a one-off inspection your board orders because of a leak, cracking, or an insurance claim. That's different from the statutory Milestone/SIRS reports, but it uses the same kind of licensed professional and often feeds into the same reserve planning conversation. Bottom line: if someone on your board says 'we need an engineering report,' the first question is which one, because the scope, cost, and legal deadline attached to each are different. Confirm with your association's counsel and county building department which requirement applies to your specific building.

What is a reserve study?

A reserve study is a financial and physical analysis of an association's common property components (roofs, pavement, pools, elevators, structural elements) that projects when each will need replacement and how much that will cost. It produces a funding schedule so the association can save toward those costs instead of hitting owners with a surprise special assessment. A typical reserve study has two parts: a physical analysis (inspecting and estimating remaining useful life of each component) and a financial analysis (current reserve balances, contribution rates, and a multi-year funding plan). Reserve study providers are often engineers, but not always. Some states let reserve specialists or certified reserve planners do this work without an engineering license, depending on the scope. In Florida, the newer Structural Integrity Reserve Study (SIRS) requirement is narrower and stricter than a generic reserve study. SIRS must be performed by a licensed engineer or architect and covers specific structural components: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing, electrical systems, plumbing, waterproofing, and exterior painting, among others listed in the statute ^[1]. For more on how these studies are built and what they should include, see reserve study and the hoa reserve study breakdown.

What is a reserve study for HOA associations specifically?

For a homeowners association (as opposed to a condo association), a reserve study covers common elements the HOA is legally responsible to maintain: roads, retention ponds, clubhouse structures, pool decks, gates, sometimes shared roofs in townhome-style HOAs. The core purpose is identical to a condo reserve study: figure out what's aging, what it'll cost to fix or replace, and how much money needs to be set aside each year. Florida's SIRS and Milestone Inspection statutes under Chapter 718 apply specifically to condominiums, not to single-family HOAs. Florida Statute 720 (covering homeowners associations) does not currently impose the same structural reserve study mandate that condos face. That said, many HOA boards choose to commission a voluntary reserve study anyway, because underfunded reserves are the single biggest cause of ugly, unplanned special assessments regardless of what statute technically applies to you. If your HOA includes multi-story buildings (some townhome and low-rise HOA developments do), it's worth asking your engineer and attorney whether any of the condo-specific structural requirements could apply by virtue of how the community is legally structured. This is genuinely a gray area in some developments and it's not something a board should guess about.

What is an HOA assessment and how does it relate to engineering reports?

An HOA assessment is a fee the association charges owners to fund operations and reserves. There are two basic types: regular (annual or monthly) assessments that cover routine expenses and reserve contributions, and special assessments, one-time or limited-duration charges levied when there isn't enough reserve money to cover a specific cost. The connection to engineering reports is direct and financial. When an engineering report or SIRS reveals that a roof needs replacement in three years at a projected cost of, say, $400,000, and the reserve account only has $60,000 earmarked for it, the board has two choices: raise regular assessments significantly now, or levy a special assessment later (often a much bigger, more painful number) when the work becomes unavoidable. This is exactly why Florida lawmakers tied SIRS to funding rules. Under the current statute, associations subject to SIRS cannot waive or reduce reserve funding for the components covered by that study, starting with the fiscal year following the SIRS deadline ^[1]. In plain terms: once your SIRS report is done, the board loses the ability to vote to underfund those specific reserve line items. For the mechanics of how a special assessment actually gets levied and communicated to owners, see hoa special assessment.

How much should an HOA have in reserves?

There's no single dollar figure that applies to every association, because it depends entirely on the age, size, and component inventory of the specific buildings. The honest answer is: enough to fully fund the projected replacement cost of every major component by the time it needs replacing, based on its remaining useful life. Reserve professionals typically describe funding health using a 'percent funded' metric: the ratio of actual reserve cash on hand to the theoretical fully-funded balance at that point in a component's life cycle. National reserve study data compiled by the Community Associations Institute and various state studies has repeatedly found that a large share of associations are well under 100% funded, with many operating below 50-70% funded, a level considered financially weak by industry reserve specialists. For Florida condos covered by SIRS, the math is no longer optional or estimate-based. Starting with reports due December 31, 2024 (extended in some cases; confirm current deadlines with counsel), associations must fund reserves for SIRS-covered components at a level that fully funds their replacement cost, without the option to underfund or waive those specific items ^{[1] [2]}. A rough industry rule of thumb some reserve specialists use: aim for at least 70% funded as a minimum comfort zone, with 100% being the ideal for a mature, low-risk community. But this rule of thumb isn't written into Florida law; the statutory requirement for SIRS components is full funding, not a percentage target.

What are HOA assessments and how are they decided?

HOA assessments (both regular and special) are set by the board, usually based on the annual budget and any reserve study or engineering findings, and are binding on all owners per the association's governing documents and applicable Florida statute. Owners don't get to opt out just because they disagree with a project. For condominiums, Florida Statute 718.112 and related sections govern how assessments are levied, noticed, and challenged. Boards generally must provide advance written notice of a meeting where a special assessment will be considered, and the amount and purpose must be specified ^[1]. For homeowners associations, Florida Statute 720.303 covers similar procedural requirements, including notice for meetings where special assessments are on the agenda. A board cannot unilaterally invent a huge special assessment out of nowhere and expect it to survive owner challenge if the process (proper notice, board vote, documentation tying the assessment to an actual need like a milestone inspection repair) wasn't followed. This is exactly where a documented engineering report matters most: it's the paper trail that justifies the number to owners, lenders, and, if it ever comes to it, a judge.

How much does a reserve study cost?

Basic HOA reserve study	$2,000 - $6,000	Reserve specialist or engineer
Full condo SIRS	$5,000 - $25,000+	Licensed engineer or architect
Milestone Phase 1 inspection	$3,000 - $15,000	Licensed engineer or architect
Milestone Phase 2 (if triggered)	$15,000 - $75,000+	Licensed engineer or architect	These ranges are directional, not quotes. Get at least two or three proposals from licensed engineering firms before committing, and confirm the scope matches exactly what your statutory deadline requires. For more detail on scoping and comparing quotes, see reserve study for condo association.

Reserve study costs in Florida generally range from about $3,000 to $15,000 or more, with the wide range driven by building size, number of components being evaluated, and whether it's a basic reserve study or a full statutory SIRS requiring an engineer's seal. A small HOA with a handful of common elements might pay on the low end, closer to $2,000-$5,000, for a basic financial/physical reserve study from a reserve specialist. A large, aging high-rise condo needing a full engineer-conducted SIRS covering a dozen structural and mechanical components can run $10,000 to $25,000+ depending on square footage, number of buildings, and site access difficulty. Milestone inspections, which are separate from SIRS but often bundled by the same engineering firm, add their own cost, typically ranging from a few thousand dollars for a small building's Phase 1 visual inspection up to tens of thousands for a large complex requiring Phase 2 destructive testing. | Report type | Typical cost range | Who performs it |

Are HOA special assessments tax deductible?

Generally, no, not for the individual condo or HOA owner on their personal federal income taxes. Special assessments used for capital improvements or major repairs to common elements are typically treated as an addition to the owner's cost basis in the property, not as a deductible expense in the year paid. The IRS doesn't have a page specifically titled for HOA special assessments, but the general rule comes from how home improvements are treated under IRS guidance in Publication 523 on selling your home: amounts paid for permanent improvements or betterments that increase the value of the property are added to basis, reducing capital gains tax when the property is eventually sold, rather than being deducted immediately ^[3]. There's a narrow exception: if part of a special assessment is specifically for repairs (not improvements) on a property used as a rental, that portion may be deductible as a rental expense in the year it's paid, subject to normal landlord tax rules. Owners who use their unit as an investment property should talk to a CPA, because the improvement-versus-repair distinction gets genuinely fuzzy in real special assessment scenarios (a full roof replacement, for example, usually counts as an improvement, not a repair). This isn't tax advice, and boards shouldn't try to answer this question for owners. Point owners to a CPA or tax attorney when this comes up, which it will, especially after a big assessment tied to milestone inspection repairs. See condo special assessment insurance for how insurance proceeds interact with assessment amounts, which also affects the tax picture.

What does Florida law actually require for milestone inspections?

Florida Statute 553.899 requires condominium and cooperative buildings that are three stories or more in height to undergo a Milestone Inspection. The trigger is 30 years after the certificate of occupancy date, or 25 years if the building is within three miles of the coastline, and then every 10 years after that ^[4]. The statute specifically states the inspection must be performed by a licensed engineer or architect and includes both a visual (Phase 1) inspection and, if that reveals 'substantial structural deterioration,' a more invasive Phase 2 inspection ^[4]. Florida's Department of Business and Professional Regulation (DBPR) maintains licensing oversight for the engineers and architects who can legally perform these inspections and provides license verification tools for the public. Local building departments, not the state directly, are the ones who enforce the deadline and can require compliance. Each county or municipality may set its own local procedures for how the milestone report gets filed and reviewed, so check with your specific county building department, more than the state statute, to confirm your exact deadline and filing process. See our full breakdown at milestone inspections hub content for county-specific detail.

How does the SIRS deadline connect to reserve funding?

The Structural Integrity Reserve Study (SIRS) requirement, added by Florida Statute 718.112 and related provisions after the 2022/2023 legislative sessions, applies to condominium buildings three stories or higher. The original statutory deadline for the first SIRS was December 31, 2024, though the legislature has adjusted timelines and provided some phased relief in subsequent sessions; confirm your building's current deadline with your association's counsel, since this has changed more than once. Once a building's SIRS is complete, the law requires the association's reserve budget to include full funding (not partial, not waived) for the specific structural components identified in that SIRS, starting with the next fiscal year budget adopted after the study ^[1]. This is a meaningful change from the old rule, where owners could vote at a meeting to waive or reduce reserve contributions almost entirely. Florida Statute 718.112(2)(f) states associations 'may not determine to provide no reserves or less reserves than required' for SIRS-covered components once the study is completed ^[1]. That's a direct legal mandate, not a suggestion. For background on the broader relief and phase-in provisions some legislative sessions have granted certain associations, see florida condo reserve fund relief.

What should a board actually do with an engineering report once it's in hand?

Getting the report is the easy part. The harder part, and the part most boards fumble, is turning a 40-page PDF full of engineering jargon into an actual action plan with dates, dollar amounts, and owner communication. At minimum, a board should: schedule the required repairs and re-inspections against real calendar dates (not vague 'sometime next year' language), update the reserve budget to reflect the report's findings, and send owners a clear written summary of what was found and what it'll cost them, before the assessment vote, not after. A lot of boards also struggle simply keeping track of which report is due when, especially associations self-managing without a dedicated management company. This is the exact gap a tool like the $199 one-time Building-Specific Board Compliance Kit is built to close: it doesn't do the inspection or replace your engineer, but it organizes the deadlines, keeps the paperwork trail, and helps the board communicate findings to owners in plain language. You can build one for your specific building at /board-kit-builder. Whatever tool or process you use, the report itself, and any decisions the board makes based on it, need to be documented in board minutes and kept in the association's official records. That paper trail is what protects the board if an owner later challenges an assessment.

Who is qualified to write an HOA engineering report or reserve study?

For Florida's statutory Milestone Inspections and SIRS, the law requires the work to be performed by a professional engineer or architect licensed in Florida. Statute 553.899 specifically names 'a licensed engineer or architect' as the only professionals authorized to conduct milestone inspections ^[4]. For a general (non-statutory) reserve study, the requirements are looser. Many firms performing reserve studies employ reserve specialists who hold credentials like the Reserve Specialist (RS) designation from the Community Associations Institute, and these professionals don't need to be licensed engineers for a basic financial/physical reserve study that doesn't touch the statutory SIRS requirement. However you shop for a provider, check that any engineer is currently licensed through DBPR's license verification system before signing a contract. A lapsed or suspended license invalidates the credibility (and possibly the legal sufficiency) of the report, and boards have been caught flat-footed discovering this after the fact. Get references from other associations of similar size and building type, and ask specifically how many milestone/SIRS reports the firm has completed under the current Florida statute, since this is still a relatively new area of practice for many engineering firms.

Frequently asked questions

What is a reserve study?

A reserve study is a report that inspects an association's major shared components (roofs, pavement, structural elements, pools, elevators) and projects when each will need replacement and how much it'll cost. It combines a physical inspection with a financial funding plan so the association can save gradually instead of relying on emergency special assessments.

What is a reserve study for an HOA?

For a homeowners association, a reserve study covers the common elements the HOA maintains, like roads, retention ponds, clubhouse buildings, and shared amenities. It works the same way as a condo reserve study, projecting replacement timelines and costs, though Florida's SIRS mandate under Chapter 718 currently applies to condos, not standalone HOAs.

What is an HOA assessment?

An HOA assessment is a fee the association charges each owner to fund shared expenses, reserves, and repairs. Regular assessments recur monthly or annually; special assessments are one-time charges levied when reserves fall short of an actual repair cost, often tied to an engineering report or milestone inspection finding.

How much should an HOA have in reserves?

There's no universal dollar figure; it depends on your building's component inventory and age. Many reserve specialists suggest at least 70% funded as a minimum comfort level, though Florida SIRS-covered condo components now legally require full funding, not partial, per the statute's reserve waiver restrictions.

How much does a reserve study cost in Florida?

Basic HOA reserve studies typically run $2,000 to $6,000. A full statutory SIRS for a condo, requiring a licensed engineer's seal, usually costs $5,000 to $25,000 or more depending on building size and number of structural components evaluated. Get multiple quotes from licensed firms before committing.

Are HOA special assessments tax deductible?

Generally no, on federal personal income taxes. Special assessments for capital improvements typically get added to your cost basis in the property rather than deducted immediately. A narrow exception exists for rental properties where a portion covers repairs rather than improvements. Talk to a CPA for your specific situation.

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

A Milestone Inspection (Florida Statute 553.899) is a structural safety check required for condos 3+ stories at 25 or 30 years, depending on coastal proximity. A SIRS (Structural Integrity Reserve Study) is a separate reserve-funding study covering specific structural components, both required under Chapter 718 for the same category of buildings.

Who can legally perform a Florida milestone inspection?

Only a licensed engineer or architect can perform a Florida milestone inspection, per Statute 553.899. Boards should verify the professional's current license through Florida DBPR's license lookup before signing a contract, since a lapsed license can invalidate the report's legal standing.

When is a condo's milestone inspection due in Florida?

Buildings 3+ stories must complete their first milestone inspection by 30 years after the certificate of occupancy, or 25 years if within 3 miles of the coastline, then every 10 years after. Confirm your exact deadline with your county building department, since local filing procedures vary.

Can an HOA waive or reduce reserve funding in Florida?

For condo associations with SIRS-covered components, no. Once the SIRS is complete, the association cannot vote to waive or underfund reserves for those specific structural items starting the next fiscal year's budget. Non-SIRS reserve items and standalone HOAs may still have more flexibility; confirm current rules with counsel.

Does a general reserve study need to be done by a licensed engineer?

Not necessarily. A basic reserve study can be performed by a certified reserve specialist without an engineering license. But Florida's statutory SIRS, tied to the milestone inspection requirement for condos 3+ stories, specifically requires a licensed engineer or architect to prepare it.

What happens if a board ignores an engineering report's findings?

Ignoring documented structural findings exposes board members to potential liability and exposes owners to safety risk and larger future costs. Local building officials can also take enforcement action if statutory milestone or SIRS deadlines are missed. Document every decision in board minutes regardless of what the board chooses to do.
