Site signage for builders and owner-builders

WA builders are required to display their registration details, or risk being fined. Read on to ensure your site signage complies!

When carrying out building work in WA, the law requires registered builders and owner-builders to display signage detailing their registration information on their building sites.  The site signs are subject to strict requirements governing the information shown, size and location.

What information must be shown on a site sign?

For registered building companies:

  • company’s full registered name (including pty ltd)
  • company’s registration number
  • telephone number
  • nominated supervisor’s full name and
  • nominated supervisor’s registration number.

For registered building partnerships:

  • full names of all partners
  • registration numbers for all partners
  • telephone number
  • nominated supervisor’s full name and
  • nominated supervisor’s registration number.

For registered builders as individuals:

  • registered individual’s full name
  • registration number and
  • telephone number.

For owner-builders:

  • owner-builder’s full name
  • owner-builder approval number and
  • telephone number.

Can any other information be included on a site sign?

Although it is not required by the legislation other information may be displayed on site signs.  This may include, but is not limited to:

  • company logo
  • trading name (a company’s full registered name must still be shown)
  • phone numbers for the nominated supervisor, emergencies or out of hours
  • business address
  • email address and
  • membership with industry organisations.

When deciding whether or not to include additional information it is important to ensure that all of the information required by law is still clearly legible.  It may be worthwhile having a separate sign for particular information, including important details related to site safety.

Work, health and safety (WHS) obligations are different to builder registration obligations.  A sign for the purpose of meeting a builder’s registration requirements will not meet the requirements of a safety sign that forms part of a builder’s WHS system.

HIA has a range of safety signage available for purchase, in addition to our general safety services.

Where should site signs be located?

Signage should be prominently and securely positioned, and details must be clearly and easily legible by members of the public.  Possible locations may include mounting the sign on a post in close proximity to the front boundary or securely fixing the sign to the front boundary site fence.

What size do site signs need to be?

There is no specific requirement for the size of site signage, however the size of the sign may be informed by its location on the site and proximity to public space.

What happens if site signs are incomplete or not correctly displayed?

If you do not have a compliant sign displayed correctly on your building site you may be fined up to $1,000 for individuals and partnerships and up to $5,000 for companies.

Do the same requirements apply to advertising?

The law requires a registered builder to display its registration number in any published advertisements relating to building work.  An individual or a partnership could face a fine of up to $5,000 in the event it fails to display its registration details and fines may be up to $25,000 for a company.

Are any other trades required to display their registration details?

In Western Australia there are various other trades that have similar site signage and advertising requirements, for example painters, plumbers and electricians.  Registered building surveyors also have specific requirements for display of their business and registration details.
