    Question Earthquake Strapping

    Just did an inspection on what is called a RV park, but the homes are secured as a mobile home would, however the water heater was actually under the sink and accessible from the outside, it was an electric and I think 19 gallon.would this require strapping, I see nothing about this size of needing anything.

    Well I'm not in California, but please post the relevant code section that specifies the tank size and strapping requirements/exclusions, and we'll go from there. I thought all tanks required some form of strapping.

    Also not from CA, but the first thing to do is to establish whether that is a "manufactured home" ("mobile home") or a "modular home".

    Manufactured homes are built to the HUD code, modular homes are built to the building code.

    The next thing to do, or maybe you already have, is to get the CA requirements for strapping of water heaters and determine what it states it is applicable to.

    Gunnar will likely have the answers to CA.

    Hey Joe,

    I know nothing about RVs, so I can't comment on those. However, if it walks like a duck...

    In addition to manufactured/mobile homes, there are also very similar units called "Park Models" and "Park Trailers". These are more of a semi-permanent installation, but are intended to be moved. Just not as often or easily as a travel trailer. I have little real knowledge about them. To the best of my knowledge, these differ from MHs in size and jurisdiction. A MH must be a minimum of 320 sq.ft and falls under the jurisdiction of CA Housing and Community Development where Park Models and Park Trailers must be less than 450 sq.ft. and I have no idea what department has jurisdiction, but I believe they are considered RVs.

    So, the size might help to guide you to decide if this is a manufactured home or a park model/trailer.

    According to the California Health and Safety Code, water heaters in manufactured homes and mobile homes are required to be seismically braced. As stated above, I believe California regards park models as an RV, but I would think that water heaters should be braced for when they travel down the highway as well as seismically.

    hey joe,
    appears to be a bradford white unit
    all their install/service manuals as with most mfr spec
    Note: For California installation this water heater must be braced, anchored, or strapped to avoid falling or moving during an earthquake. See instructions for correct installation procedures. Instructions may be obtained from DSA Headquarters Office, 1102 Q Street, Suite 5100, Sacramento, CA 95811.

    advising an upgrade is within the written word regardless of housing type
