Plan Review Services

Advanced Code Group (ACG) has been performing plan review services for municipalities, architectural firms, third-party agencies, contractors and code officials for over 10 years with great success and response. We would be happy to assist you with your I-Code plan review needs, whether on a limited or full time basis. Plan review is performed by several experienced inspectors, certified as plan reviewers in different disciplines. We offer expedited plan review services electronically. This has been a well received process that eliminates reprinting of drawings. At the end of plan review, you have the option to accept an electronic stamp on the plans or submit the final, approved drawings for traditional stamping with return via FedEx. Why print, submit then print changes and submit again when this can be done just once?

We will always do our best to work within your budget and allotted timeframe. Feel free to contact our office at 1-877-223-4462 or email us at for further information or just to discuss your needs.

Thank you,

Jeff Remas

  • Meter separation distance

    2009 IBC / NEC 2008

    A customer would like to relocate the electric meter next to the gas meter. I'm not familiar with electrical codes at all. Is there a minimum distance per the electrical code to keep the electric meter away from the gas meter / service?

    Thanks in advance.
    I love making up my own code interpretations, don't you?

    I am a plan submitter, not a plan reviewer.

    Usually the power company wants 3 feet from the venting on the pressure regulator......I do not know if there is a particular code section on this one.....I've looked for it residentially and not found it...never had the problem commercially.....
    Boy it's hot!.....And where are we going in this handbasket?

      Requirements are usually from electric co and/or gas co. I would make 2 phone calls.

        Southern California Edison require minimun 24" seperation between panel & gas meter.

          The NEC does not have any distance requirements for electric meters. This requirement will come from the utility companies.

          Questar Gas requires 3' of separation from the gas meter and the electrical meter in my area.

            Yup......local service providers requirements.
            Arguing with an inspector is like wrestling with a pig in mud, pretty soon you realize that the pig is enjoying it!

                Our gas supplier measures to the edge of the enclosure instead of the source of ignition.
                See if the gas supplier will allow piping the regulator vent opening if not otherwise feasible; IFGC 410.3.1

                Gas meters shall be located at least three (3) feet (0.9 m) from sources of ignition. [NFPA 54:]

                    FV....I think NFPA 54 also has an exception for utility meters ( like IFGC per GT) least our version (1994 I think)....
                    Boy it's hot!.....And where are we going in this handbasket?

                      Iím not sure either; I usually place a call to our gas company for verification.

                      Expanding on my reply to the OP where having a working relationship with the gas supplier and their existing gas meter may offer this option of vent piping the regulator opening away from sources of ignition such as electrical cabs, heat pumps/AC units etc., within the 3 ft. area. Iím not completely familiar with sections of NFPA 54 but apparently it may allow the provision to pipe the vent opening elsewhere since they have their meters inside buildings.

                      Too often this situation happens after the fact since apparently the POCO field personnel and the electricians are not aware of this gas code. If we can catch this before hand and conclude there is not another safe and feasible option available; discuss the situation with the gas company to agree that the exception does not become the rule.
