Mold Inspection Report Template: Section-by-Section Format with Example Language

Most mold inspection report templates in circulation are a cover page, a findings box and a page of disclaimers. That is enough to look like a report and not enough to work as one. An assessment report has three readers who were not in the building: the remediation contractor who scopes the job from it, the client's insurer or attorney who may have to rely on it, and the assessor who comes back for clearance and checks the property against it. The template below is built for those readers. It follows the section order of a full assessment report, the same order MoldMind's own reports use, and gives example fill-in language for each section. The reasoning behind each section, and the omission that most often weakens it, is in how to write a mold inspection report.

Bracketed text in the examples is a placeholder. The figures in the examples are illustrative only.

Sample mold inspection reports

If you want to see the finished format before reading the template, MoldMind publishes the four documents it produced for one demonstration job: the sample assessment report (PDF), which includes the laboratory report and chain of custody as appendices, the sample remediation protocol (PDF), the sample clearance report (PDF) and the sample client summary letter (PDF). A "mold test report" in the narrow sense is the laboratory's analysis sheet; the assessment report is the document that interprets it, and the template below is for that document.

1. Cover and report identification

The cover identifies the document without anyone opening it: report type, property address, client, inspection date, report date, project number, and the assessor's name, firm and credential or license.

Mold Assessment Report. [Property address]. Prepared for [client name], [owner / buyer / tenant / property manager]. Inspection date: [date]. Report date: [date]. Project no. [number]. Prepared by [assessor name], [credential or license no.], [firm].

2. Executive summary

One or two paragraphs that lead with the most significant finding, name the moisture source, give the approximate affected area and state the headline recommendation. Severity is described in building terms (extent of growth, whether moisture is active, urgency of remediation), not as a health risk.

Active fungal growth was identified on the [material] in the [area], attributable to [moisture source]. The affected materials total approximately [x] sq ft across [n] areas. The moisture source [is active / was assessed as inactive at the time of inspection, based on (evidence)]. Remediation is recommended under a written remediation protocol, after [type of contractor] corrects [source].

3. Scope of work and methodology

Purpose of the inspection, areas inspected and areas not inspected, and the methods used. State the question any sampling was meant to answer: IICRC S520 and the EPA treat sampling as a tool for a specific question, not a default (EPA, Mold Remediation in Schools and Commercial Buildings). Name the moisture meters and what they were used on.

Purpose: [client's question, e.g. "evaluate the source and extent of ceiling staining in Bedroom 3 before purchase"].

Areas inspected: [list]. Not inspected: [list, with reason, e.g. "garage storage loft, no safe access"].

Methods: visual inspection; pin-type moisture meter on solid wood framing and decking; pinless meter on painted gypsum surfaces; spore-trap air sampling at [n] indoor locations and one same-day outdoor control, [volume] L each; tape-lift sample at [location]. Sampling was used to [establish whether the airborne spore profile in Bedroom 3 differs from outdoor air / confirm growth on the stained ceiling paper]. [All air samples were collected before any invasive opening.]

4. Property description and environmental conditions

Building type, age, construction, foundation, HVAC type and location, and anything about the building that bears on moisture. Then the conditions at the time: temperature, relative humidity and dew point by location, outdoor weather, and whether the HVAC was running. A climate zone can be noted as context for the season and the outdoor background. Do not grade a field reading as passing or failing ASHRAE 160; it is a design and analysis standard, not a field test (see ASHRAE 160).

[Two-story single-family residence, built (year), vinyl siding over wood frame, full basement, attic air handler on a plywood platform.] Conditions on [date]: Bedroom 3 [74°F, 58% RH], attic at the platform [79°F, 68% RH], outdoor control location [68°F, 71% RH], overcast after overnight rain. HVAC off for the duration of sampling.

5. Findings by area

One subsection per room or area, in the order you walked it: what was seen, where, how much, the moisture source where it could be identified, and the photographs that show it. Give an approximate area or a dimension for every finding, because the protocol's quantities and the clearance boundary both come from it.

Bedroom 3, west partition wall. Tide-line staining on the painted gypsum board from the floor to approximately 24 in. above it, over the full 11 ft length of the wall (approximately 22 sq ft). An inspection opening at the base showed dark growth on the cavity face of the board and on the bottom plate (Photos 14–16). The staining is continuous with the ceiling staining above and follows the condensate path from the attic platform.

6. Moisture survey

A table, one row per reading: location, material, instrument and mode, value, the reference reading on unaffected material of the same type, and a status. The reference is what turns a number into a finding; IICRC S500 calls it the dry standard and publishes no fixed percentage to replace it (IICRC, S500). ASTM D7438 covers field calibration and use of hand-held moisture meters on wood; cite it for readings on wood framing and decking, not for gypsum, masonry or carpet (ASTM D7438).

Example rows:

7. Sampling and laboratory results

A sample inventory (ID, type, location, volume or area, time), the laboratory and its report number, and the results. Spore-trap analysis is commonly direct microscopy per ASTM D7391. The chain of custody and the lab report go in the appendices.

Interpretation is comparative. Each indoor result is read against the same-day outdoor control, genus by genus as well as in total, and against the visual and moisture findings (AIHA, Recognition, Evaluation, and Control of Indoor Mold). Many assessors flag a genus that runs roughly twice the outdoor count or more as a screening indicator. That is a trade convention, not a limit set by AIHA, the EPA or IICRC S520, and none of them publishes a numeric spore-count threshold (EPA, A Brief Guide to Mold, Moisture and Your Home). If your report uses the convention, say that it is one. Surface samples are reported in the laboratory's own semi-quantitative terms, quoted as the lab wrote them, not converted to counts. More on the comparison is in interpreting indoor/outdoor ratios.

Aspergillus/Penicillium-like spores in Bedroom 3 (S-204) were approximately [7] times the same-day outdoor control (S-201), and Chaetomium was detected indoors and absent from the outdoor sample. The living room and primary bedroom samples were at or below outdoor levels for every genus. Read with the visible growth and the moisture readings in the west wall, the Bedroom 3 result is consistent with an indoor source in or communicating with that room. The [2x] flag used above is a screening convention, not a standards-body threshold. Tape lift S-206 (attic-side ceiling paper): Chaetomium [heavy (4+)], Stachybotrys chartarum [moderate (3+)], as reported by [laboratory], report [number].

8. Conclusions: IICRC S520 condition by area

Assign a condition per area, not per room, and trace each one to the evidence behind it. IICRC S520 describes three condition categories: Condition 1, normal fungal ecology; Condition 2, primarily settled spores or fragments that originated from a Condition 3 area, which may include traces of actual growth; Condition 3, actual growth (IICRC, S520). Two rules keep this section defensible. Condition 2 is not a label for growth you suspect but have not confirmed: that area's condition is not determined, and the report says what investigation would determine it. And an elevated moisture reading on its own does not establish a condition. Keep any square-footage total for a condition limited to the areas assigned that condition. The fuller treatment is on the S520 report requirements page.

Attic platform and joist bays 2–4 (approx. 55 sq ft): Condition 3. Basis: visible growth on the decking and attic-side ceiling paper (Photos 3–6), tape lift S-206, decking at [26.4% MC] against a [9.8% MC] reference.

Hallway ceiling at the Bedroom 3 junction (approx. 10 sq ft): condition not determined. Tide-line staining on the same migration path; no opening or sample was taken at this location. The remediation protocol should include an investigative step here before the area is scoped.

Moisture source: overflow of the attic air handler's secondary condensate pan. [The drain stub is capped and no float shutoff is installed.] The source is not considered controlled until both are corrected.

9. Recommendations

Numbered and prioritized, source correction first, each tied to a conclusion. Say who corrects the source where you can tell (plumber, roofer, HVAC contractor). Recommend that remediation proceed under a written protocol, and keep the protocol a separate document where the state treats it as one; the mold remediation protocol template covers that document. Say that clearance criteria will be set in the protocol before work starts.

1. Before remediation: a licensed HVAC contractor terminates the secondary pan drain, installs a float shutoff and documents the work by invoice.
2. Remediation: remediate the Condition 3 areas in Section 8 under a written remediation protocol, with an investigative step at the hallway ceiling.
3. Verification: post-remediation verification by an assessor independent of the remediation contractor, against clearance criteria stated in the protocol.

10. Standards referenced

List each standard by name with the purpose it served in this report. Cite a section number only if you have read that section; the full texts of S520, S500 and the AIHA and ASTM documents are purchased, and an invented section number is the easiest line in a report to disprove (see the complete S520 guide).

IICRC S520, Standard for Professional Mold Remediation: condition categories applied to each area. IICRC S500: comparative dry-standard method for moisture readings. AIHA, Recognition, Evaluation, and Control of Indoor Mold: comparative indoor/outdoor interpretation. ASTM D7391: laboratory method for the spore-trap samples. ASTM D7438: meter calibration and use for readings on wood.

11. Limitations

Say what the report does not cover, and make the boilerplate match what you actually did. A standard "no invasive testing" paragraph contradicts a report that describes an inspection opening.

This report reflects conditions observable on [date] in the areas listed under Scope. Except where this report describes an inspection opening [or lifted flooring], concealed cavities were not opened. Conditions in areas not inspected, or that develop after the inspection date, are outside this report. The assessor is not a medical professional and this report is not medical advice; spore results cannot predict whether any individual will experience health effects.

12. Certification, signature and appendices

The certification states that the report is the assessor's professional opinion, followed by name, credential or license, signature and date. In Texas the consultant signs and dates each report and includes the license number and its expiration date (16 TAC §78.52(f)(6)). Appendices: the complete photographic record, dated and captioned by location (see the photo documentation guide), the laboratory report and the chain of custody.

I, [name], certify that this report reflects my professional opinion based on the inspection conducted on [date] and the laboratory analysis dated [date]. [Signature] [Name], [license no. and expiration date / certification and number]. Date: [date].

Where state rules add to the template

Texas, New York and the District of Columbia put document contents into rule; other licensing states regulate who may do the work, and Florida prescribes nothing about report content. In Texas the assessment report includes "the observations made, measurements taken, locations of samples collected, analysis results, and analysis and interpretation of results" (16 TAC §78.52(b)(4)), which Sections 5 to 8 above carry; see Texas mold assessment report requirements. New York's NY Labor Law §945 prescribes the remediation plan rather than the assessment report; see New York mold assessment requirements. For the District, see District of Columbia. The clearance document that closes the job has its own template: mold clearance report template.

How MoldMind fills the template

MoldMind produces this structure from the job's field data rather than a blank document: findings per area with the moisture source, moisture tables built from the recorded readings with their reference, sample inventories and indoor/outdoor tables built from the lab data, an S520 condition per area that leaves undetermined areas undetermined, limitations that reflect any invasive work described, and a signature block that carries a Texas license number and expiry. The remediation protocol, clearance report and client letter come from the same job. The inspector reviews and corrects every report before it is finalized. See the sample report.
