Baseline vs. Enhanced Scope: What ASTM E2018-24 Leaves Optional in a Property Condition Assessment

Short answer: ASTM E2018-24 defines a baseline property condition assessment and then, in its nonmandatory Appendix X1, lists the ways a user can extend it. The additions that matter most in practice are specialist involvement on high-cost systems, an opinion of long-term costs, service company research, and verified measurements and counts. None of these are automatic. All of them are scoping decisions made before the field work, and all of them should appear in the proposal rather than in a conversation after the report is delivered.

What baseline actually means

The baseline process in E2018-24 is a defined, repeatable scope: a walk-through survey of the property and its systems, a review of documents and interviews with knowledgeable parties, and a property condition report identifying physical deficiencies with opinions of cost. It is designed to be commercially reasonable - good information at a proportionate price.

The standard is unusually direct about what that costs you in certainty. Appendix X1.2 states that the baseline process is subject to a moderate degree of uncertainty that may not be appropriate for all users, and that uncertainties can be reduced, but not eliminated, by modifications to the scope of work. It also notes that clear communication of the user's objectives and risk tolerance is what makes it possible to identify the right modifications.

That is not a caveat buried in a limitations page. It is an invitation to have a real scoping conversation, and it is the reason a good proposal asks what the report is for before it quotes a price.

The additions the standard describes

Qualifications

The appendix opens with qualifications, and it treats them as the first variable rather than an afterthought. It states that the quality of a property condition report is highly dependent on the qualifications of the field observer and the report reviewer, and that appropriate qualification levels may vary with asset type, scope, purpose, and the user's risk tolerance (X1.1). A user may direct that the field observer be augmented with specialists, or may define the level of qualifications required (X1.1.1.1). The field observer is identified in the report, and a statement of qualifications is included.

It also notes something worth repeating to anyone selecting a consultant on credentials alone: professional registration can add value but will not typically compensate for a lack of related experience (X1.2.2).

Specialists

The baseline protocol is typically performed by a single individual with general, well-rounded knowledge of building systems. The standard states that observation of high-cost or critical systems - structure, roofing, facades, elevators, and mechanical, plumbing, electrical and fire protection systems - by one or more specialists can significantly reduce the uncertainties associated with those systems (X1.2.3).

This is usually the highest-value addition on an equipment-heavy or aging asset, and the easiest to scope precisely: pick the one or two systems that carry the most cost risk on this specific property rather than adding specialists across the board.

An opinion of long-term costs

This is the addition most often assumed to be standard, and it is not. An opinion of long-term costs may be included as agreed between user and consultant (X1.2.5). It reflects major refurbishment and replacement expected during an agreed evaluation term, based on an evaluation of remaining useful life. Routine maintenance, and repair or replacement that falls to tenants or others, is generally excluded - and where responsibility sits with another party, the report should describe how that determination was made.

The standard attaches several honest qualifications to it. Inflation factors, when applied, are typically applied at a constant rate and do not represent an economic projection (X1.2.5.1). Long-term costs are an order-of-magnitude opinion that excludes design, permitting, and other costs, and can differ significantly from actual costs (X1.2.5.2). Service life varies, and the opinion is guidance on expected performance rather than a guarantee of longevity (X1.2.5.3). Users who intend to reserve funds should allow for variation in cost and timing and include allowances for unexpected costs and for the design, permitting, and fees the guide excludes (X1.2.5.5).

One restriction deserves its own sentence: the standard states that opinions of long-term costs included in property condition assessments are not considered suitable for establishing reserves for condominium and other common interest properties, which are subject to regulatory and accounting requirements the guide has not considered (X1.2.5.4). If that is your situation, a reserve study is the correct instrument, not a PCA.

Service company research

Documentation from service companies that is provided during the baseline process is considered in the report. Going further - contacting the companies servicing selected systems such as plumbing, HVAC, fire protection, electrical, roofing, or elevator systems to obtain information on general condition, the extent of major or chronic repairs and replacements, pending work, and outstanding proposals - is an enhanced item (X1.2.7). Where it is performed, the report identifies the parties contacted and the pertinent information received.

On a property with a long service history and thin owner records, this is often the fastest route to information that no single-day survey will produce.

Verified measurements and quantities

The standard distinguishes between quantities taken from drawings and quantities established in the field (X1.2.6). Parking spaces can be counted from as-built site drawings and survey, or physically counted space by space. Multifamily unit counts can be taken from owner documentation, or established by physically counting each dwelling unit - which the standard notes implies walking each building and each floor. Building areas can be determined from as-built drawings or by actual field measurement, with BOMA definitions applied unless the user specifies an alternate protocol.

Whether that distinction matters depends entirely on what the number is being used for. It is worth deciding deliberately rather than by default.

Additional observations

Some improvements are noted in a baseline report but not evaluated for condition, deficiencies, or repair cost unless agreed. The standard's partial list includes electrical generation equipment, telecom towers and equipment, electric vehicle charging stations, building and energy management systems, and tenant-owned equipment affixed to the property (X1.2.4). On properties where any of these represent real value or real liability, they should be named in the scope.

Flood plain designation

Noting whether the property encroaches on an area designated as a special flood hazard area inundated by the 100-year flood on FEMA maps, as amended, is listed as an enhanced item (X1.2.8).

How to decide what to add

The standard offers a discipline rather than a formula, and it is a good one. Start from the objective and the risk tolerance, not from a menu. Then note the caution in X1.2.1: modifications represent a balance of objectives, risk tolerance, budget, and schedule, and increases in budget or schedule will not guarantee a more robust assessment, though they should be anticipated when reduced uncertainty is wanted.

In practice, three questions usually settle it. What is the single system on this property most capable of producing a surprise, and would a specialist meaningfully reduce that risk? Is this report going to be used to build a budget beyond the immediate term, and therefore does it need an opinion of long-term costs? And are there quantities in this transaction - units, parking, area - where being wrong would actually matter?

Frequently asked questions

Is an enhanced scope report still an ASTM E2018-24 assessment?

Yes. The appendix is part of the standard, expressly nonmandatory. When supplemental services are included, they should be identified in the report along with a description of the related activities, information obtained, findings, and opinions.

Does a more expensive scope guarantee a better outcome?

The standard says plainly that it does not. Additional budget and schedule should be anticipated when reduced uncertainty is the goal, but they do not by themselves produce a more robust assessment. The additions have to be aimed at the uncertainties that matter on the property in front of you.

Can we add scope after the field visit?

Some items, such as service company research or a long-term cost opinion, can sometimes be added afterward. Anything requiring field observation - specialists, field counts, field measurement - generally means a return visit. That is the practical argument for settling scope in the proposal.

We need reserves for a condominium association. Is a PCA the right report?

Not on its own. E2018-24 states that its opinions of long-term costs are not considered suitable for establishing reserves for condominium and other common interest properties. A reserve study performed for that purpose is the appropriate instrument. We can tell you what the building condition is; the reserve calculation belongs in a different report.
