How to Prepare for a Building Audit: The Documentation Checklist

The audit is scheduled — now what?

You have received the letter from your CPA, or the notice from your insurance carrier, or the engagement agreement from the reserve study firm. An audit is coming. The timeline is typically four to eight weeks, and the auditor is going to request a list of documents that, if you are like most boards, you are not confident you can produce completely.

This is normal. It is also avoidable.

The vast majority of audit complications — delays, qualified opinions, increased fees, and findings that reflect poorly on the board — stem from documentation gaps. Not from financial irregularities or governance failures, but from the simple inability to locate and produce the records that demonstrate your building is being managed properly.

This guide covers the three most common types of audits that condo, co-op, and HOA boards face — financial audits, insurance audits, and reserve studies — with a specific checklist for each. It also addresses the documentation gaps that auditors find most frequently and how boards can close them before the auditor arrives.

Financial audit documentation

A financial audit is the most comprehensive review your association will undergo. The auditor's objective is to examine the association's financial statements and express an opinion on whether they present the financial position of the association fairly, in accordance with generally accepted accounting principles (GAAP).

What the auditor will request

Governing documents and corporate records:

Declaration, bylaws, and all amendments
Articles of incorporation and any amendments
Certificate of good standing (current year)
Board meeting minutes for the entire audit period
Annual meeting minutes, including election results
Resolutions authorizing special assessments, borrowing, or major expenditures

Financial records:

General ledger and chart of accounts
Trial balance as of fiscal year-end
Bank statements for all accounts (operating, reserve, special) for the full audit period, plus one month after year-end
Bank reconciliations for every month of the audit period
Investment account statements, if applicable
Copies of all certificates of deposit

Revenue documentation:

Assessment schedule showing the amount assessed to each unit
Aging report of owner receivables as of year-end
Copies of lien filings and collection actions
Records of any special assessments, including the resolution authorizing them and the collection schedule
Revenue from sources other than assessments (rental income, laundry, parking, late fees) with supporting documentation

Expenditure documentation:

Invoices and receipts for all expenditures during the audit period — every invoice, not a sample
Copies of all checks issued (or digital payment records)
Contracts with all vendors, management companies, and service providers active during the audit period
Payroll records, if the association has employees, including W-2s, 1099s, and payroll tax filings
Credit card statements and receipts, if any board member or employee has a card on the association's account

Tax and regulatory filings:

Prior year tax returns (Form 1120-H for HOAs and condominiums, or the applicable form for your entity type)
Property tax records and payment receipts
State regulatory filings, if applicable (e.g., annual reports, registration renewals)

Insurance:

Copies of all insurance policies in effect during the audit period (general liability, property, D&O, fidelity bond, workers' compensation)
Insurance claims filed during the audit period and their resolution

Other:

Loan agreements and amortization schedules, if the association has outstanding debt
Reserve study (most recent)
Correspondence with attorneys regarding pending or threatened litigation (the auditor will also send a confirmation letter directly to the association's attorney)

Common gaps in financial audit preparation

Missing invoices. The most common gap. The management company paid the vendor, the check cleared, but nobody retained the invoice. The auditor cannot verify the expenditure without supporting documentation. In a worst case, missing invoices for large or recurring expenses can lead to a qualified audit opinion.

Incomplete meeting minutes. Auditors review board minutes to verify that expenditures were authorized. A $200,000 elevator modernization contract should appear in the minutes as a board-approved action item. If the minutes are incomplete or ambiguous, the auditor must perform additional procedures to confirm authorization — increasing both the audit timeline and the fee.

No reconciliation between assessments billed and assessments collected. The auditor needs to trace the assessment revenue from the billing schedule to the bank deposits. If the management company does not provide a clear reconciliation, the auditor will build one — at your expense.

Unreconciled bank statements. If the monthly bank reconciliation was not performed consistently, the auditor faces a significant increase in the work required to verify cash balances. This is one of the most expensive audit findings because the auditor must reconstruct the reconciliation from scratch.

Insurance audit documentation

Insurance audits are typically less comprehensive than financial audits but can have equally significant consequences. An insurance auditor is verifying that the association's coverage matches its actual risk profile and that the information provided during policy placement was accurate.

What the insurance auditor will request

Property and operations information:

Current property appraisal or replacement cost estimate
Building specifications (square footage, number of units, construction type, year built)
Capital improvement records for the audit period (any work that affects the insurable value of the property)
Occupancy data (percentage owner-occupied vs. rental units)

Payroll and contractor information:

Payroll records for all association employees (not management company staff, unless the association is the employer of record)
Total amount paid to uninsured subcontractors during the audit period — this is a frequent source of premium adjustments
Certificates of insurance from all vendors and contractors

Claims and loss history:

List of all claims filed during the audit period
Status of open claims
Any incidents reported to the insurer but not resulting in a claim

Financial information:

Total revenue and total expenditures for the audit period
Assessment schedule and collection rate

Common gaps in insurance audit preparation

Missing certificates of insurance from vendors. When a vendor or contractor does not carry adequate insurance, the association's policy may pick up the liability — resulting in a premium increase at audit time. Boards that do not collect and verify certificates of insurance before work begins are consistently surprised by retroactive premium adjustments.

Undisclosed capital improvements. A major renovation that increases the building's replacement value but was not reported to the insurer creates an underinsurance gap. If a loss occurs before the next policy renewal, the association may recover less than the actual cost of the damage.

Inaccurate payroll reporting. If the association reported estimated payroll at policy inception and the actual payroll was higher, the auditor will calculate the additional premium owed. This is straightforward but catches boards off guard when the adjustment is significant.

Reserve study documentation

A reserve study is not technically an audit, but the documentation requirements are similar and the consequences of poor preparation are equally significant. The reserve analyst is evaluating the current condition and remaining useful life of the building's major components and calculating the funding necessary to replace them without special assessments.

What the reserve analyst will request

Building and component information:

Original construction specifications and plans, if available
Age, condition, and maintenance history of all major components (roof, HVAC, elevators, plumbing, electrical, parking structures, facade, windows)
Records of all major repairs and replacements, including dates and costs
Warranty information for replaced components
Any engineering reports, inspection reports, or condition assessments performed during the study period

Financial information:

Current reserve fund balance with a breakdown by investment type
Reserve fund contribution schedule (how much is contributed monthly or annually)
History of reserve fund contributions and expenditures for the past five years, at minimum
Any special assessments levied for capital projects, with the amount, purpose, and collection status

Governing document provisions:

Any provisions in the declaration or bylaws governing reserve funding requirements
State statutory requirements for reserve funding (varies significantly by state — see our guide on state record-keeping requirements)

Common gaps in reserve study preparation

Incomplete maintenance records. The reserve analyst needs to assess remaining useful life, which depends on both the component's age and how well it has been maintained. A roof that was installed 15 years ago and has been inspected and patched regularly has a different remaining life than one that has received no maintenance. Without maintenance records, the analyst must assume worst-case conditions, which inflates the projected replacement costs and the required reserve contributions.

Missing cost records for prior replacements. If the building replaced its boilers eight years ago but nobody can locate the invoice, the analyst must estimate the replacement cost. Estimates are inherently less accurate than actual costs, and the compounding effect on a 30-year funding projection can be substantial.

No records of warranty coverage. Components still under warranty have different funding implications than components without warranty protection. If the reserve analyst does not know that the new windows carry a 20-year manufacturer warranty, the study will assume a shorter replacement cycle and recommend higher contributions than necessary.

The meta-problem: document fragmentation

The most important pattern across all three audit types is the same: boards struggle not because records do not exist, but because records are scattered across multiple locations and multiple people.

The management company has the financial records — most of them. The board president has some of the correspondence in a personal email account. The former treasurer has a folder of invoices from two years ago. The insurance broker has the certificates of insurance, but the copies in the association's files are from the prior policy year. The maintenance superintendent keeps a notebook with equipment service dates, but it is not digitized and not accessible to the board.

This fragmentation means that preparing for any audit requires a collection effort that takes weeks and still produces an incomplete result. The auditor identifies gaps, requests additional documents, waits for the board or management company to locate them, and the audit stretches from its scheduled four weeks to eight or ten.

A practical pre-audit checklist

Regardless of the audit type, the following steps will reduce both the preparation burden and the risk of adverse findings:

Sixty days before the audit

1. Request the auditor's document list. Every audit firm has a standard request list. Get it early and compare it against what you actually have.

2. Designate a single point of contact. One person — board member or management company representative — should be responsible for collecting and transmitting documents to the auditor. Diffused responsibility means dropped items.

3. Inventory your records. Before you start collecting, identify what you have, where it is, and what is missing. A gap identified sixty days before the audit can be filled. A gap discovered during fieldwork cannot.

Thirty days before the audit

4. Assemble documents in a single location. Physical or digital, the documents should be organized by category and accessible to the auditor without further board involvement.

5. Reconcile bank statements. If monthly reconciliations have not been performed, complete them now. This is the single most impactful step you can take to reduce audit complications.

6. Verify vendor certificates of insurance. Request updated certificates from any vendor whose certificate has expired or is missing. This applies to insurance audits specifically, but it is good practice regardless.

7. Review meeting minutes for completeness. Confirm that minutes exist for every board meeting and every annual/special meeting during the audit period. If minutes are missing, draft them now from whatever records are available (agendas, notes, email discussions) and have the board ratify them.

One week before the audit

8. Transmit the complete document package to the auditor. Provide everything you have, organized and labeled. Include a cover memo identifying any documents you were unable to locate.

9. Brief the board. Let all board members know the audit is proceeding, who the point of contact is, and that they may be contacted with follow-up questions.

10. Check your access. If documents are stored in a digital system, confirm that the auditor has the access they need. If documents are physical, confirm the location is accessible during the audit period.

Making this sustainable

Audit preparation should not be a crisis. If your board's records are centralized, complete, and searchable, preparing for any type of audit is a matter of generating the appropriate reports and transmitting them — not a weeks-long scavenger hunt across email inboxes, filing cabinets, and former board members' personal files.

BoardRecord centralizes every board communication, document, and decision in a single searchable system. When audit time arrives, the records are already organized, complete, and accessible — eliminating the fragmentation problem that makes audits painful for most boards.

BoardRecord keeps your board's complete record organized and audit-ready at all times — so the next audit is a report, not a scramble. Start a free pilot to see how it works.
