MARYLAND REGISTER, VOLUME 40, ISSUE 25,
FRIDAY, DECEMBER 13, 2013
Title 09 DEPARTMENT OF LABOR, LICENSING, AND REGULATION
Subtitle 36 COMMISSION OF REAL ESTATE APPRAISERS, APPRAISAL MANAGEMENT COMPANIES, AND HOME INSPECTORS -
09.36.07 Minimum Standards of Practice
Authority: Business Occupations and Professions Article,
§§16-208(a) and 16-216, Annotated Code of Maryland
Notice of Proposed Action
The Commission of Real Estate Appraisers, Appraisal Management Companies, and Home Inspectors proposes to amend Regulations
.01, .07, and .08 under COMAR 09.36.07 Minimum Standards of Practice. This action was considered at a public
meeting of the Commission of Real Estate Appraisers, Appraisal Management Companies, and Home Inspectors held on October 8, 2013,
notice of which was given in 40:19 Md. R. 1604 (September 20, 2013) pursuant to State Government Article, §10-506(c), Annotated
Code of Maryland.
Statement of Purpose
The purpose of this action is to amend the existing home inspector standards of practice to create a definition of CSST
(corrugated stainless steel tubing) in the home inspector standards of practice. This action also requires home inspectors to
identify the presence of CSST in a home inspection report, if observed, and to recommend to the client that the system be
inspected by a licensed master electrician to determine whether the CSST is properly bonded. This action is part of a national
safety campaign designed to bring awareness to homeowners on the importance of proper bonding of CSST due to potential damage
risks associated with lightning strikes. CSST is a flexible piping material used to distribute gas fuel service (natural gas
or propane gas) to fuel burning appliances and/or components within a building. After CSST became popular in building construction,
it was found that homes containing improperly grounded CSST struck by lightning created a very hazardous situation. Direct or
indirect lightning strikes on or near a structure have been shown to cause an electrical surge to travel into the structure and
have, in some cases, caused a perforation in the sidewall of the tubing as the energy arcs from one metallic system to another
seeking ground. This arcing can ignite the pressurized gas leaking from the perforation, and in some cases, has caused a significant fire.
Comparison to Federal Standards
There is no corresponding federal standard to this proposed action.
Estimate of Economic Impact
I. Summary of Economic Impact. There is no anticipated economic impact on licensed home inspectors. Maryland licensed
master electricians may enjoy slightly increased business as a result of the inspection of property containing CSST, for which
the property owner will be advised to have an electrician ensure that the CSST is properly bonded.
