Assessing a historic building before repairs means creating a dated, traceable record of what is visible before work changes it. Photograph and describe the building, identify where each observation was made, record what you could not access or verify, and match the level of documentation to the building’s significance and the decisions the project must support. The National Park Service advises that a building be documented before inventory, stabilization, or investigative work so its material evidence is recorded.
What should you document before repairing a historic building?
Record the building’s visible condition and significant features as they exist before work begins. A useful record lets someone else connect each observation to a particular place, understand what was seen, and distinguish a documented fact from an assumption or an unverified possibility.

The National Park Service puts the timing plainly: “A building should be documented prior to any inventory, stabilization or investigative work in order to record crucial material evidence.” Read the full guidance in Preservation Brief 35, Understanding Old Buildings: The Process of Architectural Investigation. If an immediate safety threat requires action, protect people first; record what can safely be documented without delaying necessary emergency measures.
Depending on the project, a record may include:
- Dated photographs of the exterior, interior spaces, and relevant details.
- Written descriptions of visible materials, damage, changes, and apparent extent.
- A location key, such as a plan with room and opening identifiers, so notes and photographs can be traced.
- Sketches, measurements, or measured drawings where the project or the building’s significance warrants them.
- Relevant earlier plans, photographs, repair records, and historical information, clearly distinguished from current observations.
- A statement of methods, access limits, and conditions that were not tested or could not be verified.
There is no single documentation package that fits every old building. The National Park Service’s Secretary of the Interior’s documentation standards describe levels that range from measured drawings, photographs, and written history to a sketch plan, photographs, and a short report. Choose a level that serves the purpose; a full set of measured drawings is not automatically necessary for every repair.

How do I assess a historic building before repairs?
Start by defining the decision the assessment needs to inform, then review available records and survey the building in a repeatable sequence. Document visible evidence before interpreting it, and make the limits of the assessment clear.
1. Define the purpose and boundaries
Write down what the record is meant to support: routine maintenance, repair design, a larger rehabilitation, a change in use, emergency planning, or a formal preservation submission. Identify the building, the areas and features included, the survey date, who carried out the work, the records consulted, and the methods used. Note inaccessible rooms, blocked views, unsafe areas, and anything excluded from the assessment.
Purpose and significance guide the amount and kind of documentation. A focused record of a limited repair may need photographs and concise descriptions of the affected areas; a substantial project or significant building may need historical research, measured drawings, and input from specialists. The National Park Service’s documentation standards explain how scope should reflect both the subject and the intended use.
2. Review existing information before drawing conclusions
Gather available plans, previous photographs, repair records, reports, and historical information. These can help identify earlier changes or provide context for a feature, but they do not prove the current condition. Label the source and date of record-derived information, and separate it from what the survey directly observed.
Use careful language. “Water staining is visible below the north window” describes an observation. “A roof leak caused the staining” is a conclusion that may require further investigation. Where cause, extent, or concealed damage is uncertain, record the question and identify what follow-up would be needed rather than presenting an assumption as fact.

3. Walk the property in a consistent sequence
Survey the exterior and interior systematically so coverage can be checked and repeated later. A plan is helpful, but a simple, consistent location key also works: for example, name elevations by orientation, number rooms in a defined order, and identify doors and windows within those locations. State the convention on the plan or in the report. Avoid ambiguous labels such as “back room” unless they are tied to a clear location.
Recommended Free Tools
For each observation, record where it is, what material or element is involved, what is visibly happening, and its apparent extent or pattern. Add a photograph or sketch reference and note any access or visibility limitation. An observation form can use these fields:
| Field | What to record |
|---|---|
| Identifier and location | Building, elevation or room, and a consistent element identifier. |
| Element or material | The visible feature being described, using a specific name where possible. |
| Observed condition | What can be seen, stated without assuming an unverified cause. |
| Extent or pattern | Where it begins and ends, whether it is isolated or repeated, and its visible relationship to nearby features. |
| Record reference | Photograph number, sketch, drawing, or note that documents the observation. |
| Limits | What was blocked, inaccessible, unsafe, concealed, or otherwise not verified. |
| Follow-up | Any question that needs a closer examination or review by an appropriate specialist. |
This is a practical organizing template, not a prescribed National Park Service form. Its purpose is to keep observations and supporting records connected.
4. Photograph context as well as detail
Take overall views that establish where a feature is, then closer views that show its condition. Photograph relevant elevations and interior spaces as well as significant, unusual, or repair-affected details. Give each image a number or other unique identifier, date it, and caption its location and subject. Link the identifier to the matching note, plan, or drawing.
A close-up without context can be hard to locate later; a distant view may not show the condition clearly. Use both when needed. Include a scale when useful for understanding size, and make sure it does not cover the feature. The National Park Service requires scaled views for certain documentation levels; those formal requirements apply to the relevant documentation work, not automatically to every owner’s repair record. Add a written description or sketch when a photograph alone cannot explain the location, shape, or relationship of what you observed.

5. Measure and draw to the level the project needs
Measured drawings can record existing conditions and give repair planning a spatial basis, but they require more effort than a photo-and-note record. Decide whether the repair scope, building significance, or future archival need makes that level worthwhile. The Historic American Buildings Survey drawing guidelines describe HABS drawings as “as-built” records of a building’s condition at the time of documentation.
Identify what was measured in the field and what came from another source. Do not present an inaccessible part as field-measured: label it as inaccessible or clearly identify when it was drawn from a different source. Keep field measurements and notebooks with the drawings so another person can understand and check the underlying record. The National Park Service’s Heritage Documentation Programs guidance discusses preserving primary data, including field records, and recording limitations.
6. Separate visible condition from diagnosis
A visual record is not automatically a structural evaluation, hazardous-material survey, building-systems inspection, or confirmation of concealed conditions. Say what the survey did and did not include. Do not state that a condition was tested, that a material is safe, or that a building component has a particular capacity unless the appropriate investigation supports that conclusion.
Seek qualified preservation, architectural, engineering, or conservation advice when the building is significant, deterioration is complex, a structural concern is suspected, or planned work may affect character-defining materials. The appropriate professional and scope depend on the question; there is no universal threshold in the available National Park Service guidance for when every project must hire a specialist. A historic structure report can be useful for substantial projects because it brings building evolution, physical description, existing condition, significance, and treatment recommendations together.
7. Assemble and retain the record
Organize the report, photographs, field notes, drawings, measurements, and any test results using consistent identifiers and dates. Keep primary field records, not only a summary or selected images. State the methods and scope, the records consulted, and the parts that could not be accessed or verified. A future repair team should be able to follow a reference in the report back to the relevant image, note, or drawing.

Preservation work can reveal new evidence once finishes or other materials are encountered. Update the record when that happens, and retain a post-project record of what work was carried out. National Park Service Preservation Brief 43 recommends adding annotated drawings, photographs, and other work records to a historic structure report and maintaining it as an active document.
What belongs in a building condition report?
A useful condition report explains what was assessed, what was observed, where the evidence is, and what remains uncertain. It should be specific enough to guide decisions without claiming to diagnose conditions beyond the survey’s scope.
A concise report can be organized as follows:
- Identification and purpose: building name or address, survey date, author, reason for assessment, and intended use of the report.
- Scope and method: areas covered, sequence or method of inspection, records reviewed, and any measurement or specialist work included.
- Building context: relevant history and known alterations, with sources identified and uncertainty noted.
- Location system: a plan, sketch, or written key explaining how elevations, rooms, openings, and features are identified.
- Observations: organized descriptions of visible materials and conditions, each connected to photographs, drawings, or notes.
- Limitations: inaccessible or concealed areas, restricted views, and investigations not undertaken.
- Follow-up and treatment considerations: questions needing further review and recommendations appropriate to the report’s scope.
- Record index: a clear list of photographs, drawings, field notes, references, and supporting records.
For significant buildings or substantial work, a historic structure report (HSR) may be the appropriate broader planning document rather than a brief condition summary. The National Park Service describes an HSR as documenting a building’s evolution, physical description, existing condition, and significance, then addressing treatment objectives and recommendations. It is intended to support preservation decisions and can be updated as additional evidence emerges.

Consider an HSR when a building’s significance or the project’s complexity calls for an integrated understanding of its history, physical condition, and treatment options. It is not automatically necessary for every repair, and a narrower, well-documented assessment may better fit a limited scope.
An HSR may be especially useful when work is substantial, when several repair choices could affect significant materials, or when the project needs its history and existing condition considered together. It can provide a continuing record for decisions rather than treating the report as a one-time snapshot. A small, clearly defined maintenance task may not require a full HSR; the essential point is to preserve enough reliable evidence for the decision being made.

Before commissioning one, clarify the questions the report must answer, the areas it should cover, the documentation level required, who will retain its field records, and how the report will be updated during work. If a preservation submission or archive is involved, confirm applicable requirements with the relevant authority. The National Park Service notes that federal, state, and local requirements may apply, and archive requirements may call for consultation with the relevant state historic preservation officer or state library.
How should you use the record during and after repairs?
Keep the documentation accessible to the people making decisions, and revise it when repair work reveals new evidence or changes the building. A record is most useful when its references remain intact and it reflects both pre-work conditions and completed work.
Before work, use the documented locations and observations to discuss scope and identify uncertainties that may need resolution. During work, add dated notes and annotated photographs when newly exposed conditions differ from the record; distinguish those discoveries from the original observations. After work, add drawings or photographs showing what was repaired, along with available work records and test results. Keep the files together under the same location and identifier system.
Continue documenting significant conditions as part of ongoing care. The National Park Service advises regular monitoring of historic buildings and using documentation to guide future treatments. Repeated records are more useful when the date, location, and viewpoint can be compared; do not imply that an old image alone establishes when or why a change occurred.
For projects involving hazards or other regulatory requirements, check the rules that apply to the building and location. This guidance does not determine permits, building-code obligations, preservation approvals, or archive rules for a specific property. The National Park Service resource on resilience to natural hazards and historic buildings is relevant to resilience planning, but it does not replace a site-specific assessment or applicable local requirements.
Frequently Asked Questions
How do I document a crack in an old building?
Give it a unique location identifier, describe its visible form and extent without assigning a cause, and take both a context view and a close view. If comparing it later, use a dated repeat photograph from a comparable position and retain the original image; a change in appearance is a reason to seek appropriate assessment, not by itself a diagnosis.

One-click scans. No signup required.
Can I start repairs before the condition report is finished?
If there is no immediate threat, document the affected area before work removes or changes evidence. When urgent action is needed to protect people or prevent immediate harm, prioritize safety and record what can safely be captured without delaying that action; add a clear note about what could not be documented beforehand.
Who should keep the building’s survey photos and field notes?
Agree on record custody before the project begins, including who retains the original photographs, notes, drawings, and any specialist reports. If the work has formal archive or submission requirements, ask the relevant authority what format and destination it requires.
