Where can you find the signage required in sales offices?

This would really depend on the location and industry. Regulations on signage take a number of forms.

First, different locales will pass laws to regulate the type, design, and most importantly, the size of signs posted outside of an office. These regulations can be quite restrictive, and adding signs or changing them can be next to impossible. These can be found in your local county or municipal codes. Joining your local chamber of commerce may give you access to concise guides to these procedures.

Other than that, there are federal labor guidelines that specify the posting of certain noticies in workplaces, notably the minimum wage guidelines, and equal employment opportunity (EEO) postings. These are fairly minimal. Depending on the type of sales that your office performs (perhaps automobile or home sales), Equal Credit Opportunity, or Equal Housing Opportunity signs may be required. Check with your local chamber of commerce for guides on these.

Other postings would be industry specific, such as the posting of materials safety data sheets (MSDS), or other OSHA (Occupational Safety and Health Association) regulations required by industry. Another example of industry-specific postings would include specific information required in advertisements by the state regulatory body that controls regulated professions. In Florida, for example, this is known as the Department of Business and Professional Regulation (DBPR). Other industry-specific signage could include the posting of occupational licenses of all employees in a conspicuous location within the office. These can be found in your state laws that govern your type of business, if applicable. For regulated professions, joining a professional association, or purchasing a commercially-available manual for your state will give you access to all of these conveniently.

This can also vary based on the size of your business; very small businesses, such as sole proprietorships or those with fewer than 10 employees may be exempt from many of these. This can be a tangle to keep track of, so a good book on operating your type of business office will be helpful.

If you mean simply, where can the signs be purchased, then inquire at a local office supply store. They may stock the signs, or they can be ordered from on a catalog or online store. Alternately, unique signs may be custom ordered.
