1.  Purpose



1.1  The purpose of this document is to define good
practice and to establish a reasonable approach for the performance
of an inspection of a commercial property.

2.  Definitions



2.1  Core definitions


2.1.1  Commercial Property -  A commercial property is
defined as the building structures and improvements located on a
parcel of commercial real estate.  These may include
structures such as buildings with residential units operated for
profit, mixed-use buildings, strip malls, motels, factories, storage
facilities, restaurants, and office buildings.


2.1.2  Inspection - The inspection is defined as the process
of an inspector collecting information through visual
observation during a walk-through survey of the subject
property, conducting research about the property, then
generating a meaningful report about the condition of the property
based on the observations made and research conducted by the
inspector.  A commercial inspection requires the inspector
to make observations, conduct research, and report findings.


2.1.2.1  Observations - Observations are defined as those
potential items of interest noted by the inspector during the
walk-through survey portion of the inspection.

 

2.1.2.2 
Research - Research is defined as the process of gathering
information through document review and interview to augment the
observations made during the walk-through portion of the
inspection.  This research may include reviewing readily
available documents such as previous inspection reports,
building permits, code violation notices and environmental studies.
This research may also include interviews with readily available
personnel such as building managers, tenants and owners.

 

2.1.2.3  Report - An
inspection report is defined as a written communication
describing the issues discovered from observations
made and research conducted by the inspector that are, in the
inspector's opinion, are likely to be of interest to his/her
client.  A report may contain photographs of observations made
during the walk-through survey portion of the inspection and/or
copies of documents reviewed during the research portion of the
inspection.

4.  Inspection



4.1  Objective


The objective of an inspection is to provide
written communication describing the issues discovered from
observations made and research conducted by the inspector and
that, in the inspector's opinion, are likely to be of interest
to his/her client and to enhance the client's information and
knowledge about the commercial property to improve
decision-making for buying, selling, maintaining, or improving
the property.

4.2  Who may perform
the inspection


Any portion of the inspection including the walk-through survey,
research, and report generation, may be performed by the inspector,
his/her staff, or any consultant hired by the inspector.  This
standard recognizes that for the majority of commercial inspections,
the inspector is likely an individual with a general, well rounded
knowledge of commercial properties and that the inspector or client
may want to augment the inspector's skills with specialty consultants
who have particular expertise in certain areas.  The decision to
hire specialty consultants will of course rely on budget and time
constraints as well as the risk tolerance of the client. 


4.3  Varying levels of due diligence


This standard is designed as a baseline from which the inspector
and client can develop and agree to a scope of work that may
deviate from this standard depending on budget, time constraints,
purpose of the inspection, age of the subject property, and risk
tolerance of the client.  The level of due diligence
should be set where the cost, in time and money, of
acquiring information about the subject property will not
likely exceed the value of that information.   Therefore,
an inspection performed in accordance with this standard will
not be technically exhaustive. 

 

4.3.1  Sample language for
use when defining the scope of work


"The inspection will be performed in accordance with
InterNACHIcomsop except that... "


4.3.2  Representative observations


In recognizing that the client likely has the goal of acquiring
information about the subject property at a cost, in time and money,
that does not exceed the value of that information, representative
observations are not just permitted by this standard, but
recommended as well.

4.4  Uncertainty


The client should understand that no inspection report is completely
accurate.  A report is only the written communication
of the observations made and research conducted by the
inspector.  The report contains those items which
in the inspector's opinion are likely to be of interest to
his/her client. 

4.5  Subjectivity


The client should understand that the inspection report is, to a
large degree, the subjective opinions of the inspector based
on his/her observations and research within the limits of
access, time, and budget and without the aid of special equipment
or meters and without dismantling, probing, testing,
or troubleshooting and without detailed knowledge of the
commercial property, its components or its systems.  The
inspection report is not much more than a subjective professional
opinion. 

4.6  Not an
architectural or engineering service


An inspector performing a commercial inspection in accordance
with this standard is not practicing architecture or
engineering.   

4.7  Not a warranty,
guarantee or insurance policy


The inspection is not a warranty and the inspection report is
merely the written communication of the inspector's subjective
opinion on the condition of the subject property.

5.  Research



5.1  Objective


The objective of research, including the review of
documents and the performing of interviews, is to augment the
information obtained during the walk-through survey and to
provide supporting documentation to the inspection report. 

5.2  Document procurement


It is the client's responsibility to obtain copies of all documents
and provide them for the inspector.  These documents are most
often obtained from the seller or from local government offices. 
The inspector is not responsible for gathering or paying for copies
of appropriate documents to be reviewed unless these tasks are
specifically assigned to the inspector in the scope of work
agreement.

5.3  Documents to be
reviewed and included in the inspection report


The inspector should review all documents provided by the client and
owner.  The inspector should also make an inquiry and review of
any other documents that can be reasonably procured on-site or
from the building owner or manager such as Certificates of Occupancy,
building code violation notices, repair invoices, and warranties. 
The inspector is not required to uncover and review information
that is not provided or cannot be reasonably ascertained or
acquired on-site.  Copies of documents that the inspector
believes may be of interest to the client and copies of documents
that support the inspector's opinions should be included in the
inspection report.

 

5.3.1 Examples of documents the
inspector may want to request for review


  • Accessibility surveys


  • Appraisals


  • Building plans


  • Certificates of Occupancy


  • Citations


  • Deck age records, plans and construction permits.


  • Deck and balcony maintenance, power washing, painting, treating,
    repair and modification history

  • Previous inspection reports


  • Proposals


  • Rent records


  • Repair estimates/invoices


  • Safety inspection records


  • Seller disclosures


  • Sprinkler head replacement records


  • Utility bills

  • Warranties



5.4  Interviews


The inspector should identify and interview the person(s) with the
most knowledge about the condition of the building.  Typically,
this will be the building owner or manager.  Unless otherwise
agreed to in the Scope of Work agreement, it is the responsibility of
the client to arrange to have this person(s) on hand for
interview by the inspector on the day of the walk-through survey. 

5.5  Pre-inspection
questionnaires


The inspector may request that the owner, building manager and/or
client fill out pre-inspection questionnaires to gather information. 
The inspector may rely that these responses are truthful. 
In cases where parties refuse to fill out questionnaires in
writing, the inspector may interview the parties and fill out the
questionnaires for them.  The inspector should note in the
report if he/she filled out the questionnaire based on an interview
and whether such interview was performed in person, by telephone, or
by email.  Copies of all responses to such questionnaires should
be included in the inspection report. 

5.6  Reliance


The level of accuracy of information varies depending on its source. 
The inspector may rely on information obtained to the extent that the
information appears to be accurate and complete.  This standard
does not require the inspector to independently verify the accuracy
of the documents reviewed by the inspector or included in the report
nor the statements made by those interviewed by the inspector.

5.7  Fraud


The inspector is not a fraud investigator and this standard does not
require the inspector to look for intentionally hidden deficiencies
in the subject property.  The inspection report is supplementary
to the seller's disclosures.

5.8  Previously generated
reports


A previously generated inspection report should be treated no
differently than any other document reviewed during the research
portion of the inspection and like information collected from any
other source, information obtained from a previously generated
report should reference its source in the new inspection report. 
No portion of a previously generated report should be used as a
substitute for the new inspection report.

6.  Walk-Through Survey



6.1  Objective


The objective of the walk-through survey is to allow the inspector to
visually observe the subject property, gather information and note
items of interest.

6.2  Access responsibility


It is the client's responsibility to arrange for the inspector to
receive timely access to the subject property for the
walk-through survey portion of the inspection and access to all
documents and interviewees needed for the research portion of the
inspection.  This includes access to all documents,
information, and previously generated reports in the client's
possession.  The inspector is not responsible for obtaining,
reviewing, or providing information should the source withhold,
impede or delay access.   Anything that hinders
the inspector's access should be noted in the report.

6.3  Revisits


It is expected that the inspector will perform only one
walk-through survey per inspection report.  However, it may be
necessary for the inspector to revisit certain areas of the subject
building after performing the research portion of the inspection.

6.4  Inspector safety


It is the responsibility of the inspector to perform the
walk-through survey safely.

7.  Report



7.1  Format


The report must be in writing.  This standard does not
require any one particular format.  It is InterNACHI's

clients are best served when inspectors are free to compete through
report generation innovation.

7.2  Date


The report should be dated on the first page of the report.

7.3  Inspection
firm information


The report should include the name and contact information of the
inspection firm on the first or second page.

7.4  Property address


The report should include the address of the property inspected or a
description of the real estate sufficient for identification on the
first or second page.

7.8  Opinions of shutdown
systems


The inspector should still try to render an opinion of the condition
of systems even if they were shutdown or were not
operational at the time of the walk-through survey.

7.9  Obsolescence


The client should only rely on the inspection report at the
point in time that the inspector's observations were being made
and research was being conducted.  The client should deem
the report as obsolete to some extent, even while it
is being prepared.

7.10  Site-specific


The client should understand that an inspection performed in
accordance with this standard only relates to the observations made
and research conducted.  Consequently this standard does not
address issues such as business operations at the subject
property, deed encumbrances, neighborhood conditions, etc.

7.11  Multiple buildings


An inspection report produced in accordance with this standard
may encompass more than one building within a single report.
