Can I Extend my Mezzanine Floor Without Adding Extra Posts?

One way to expand a mezzanine floor without intruding further on the floor beneath it is by bolting more floor onto the end, rather than adding extra posts beneath. There is a possibility of being able to complete this expansion without adding more posts or supports, but it largely depends on whether or not you have the original drawings for your mezzanine.

You need to discover whether you have a perimeter beam in place, or a standard beam into which cleats can be fastened so that you can extend the new row of floor joists from the existing beam in place.

It may seem and look simple to expand an existing mezzanine floor but there are potential issues around the existing structure and building regulations based on the existing floor, original install date, and current standards. One of the key factors determining whether or not you can expand your mezzanine by bolting additions on, or need to add new posts, comes from whether or not your mezzanine will still meet safety standards of load bearing, fall protection, fire safety, and structural stability. If these are negatively affected by bolting on an addition, then it cannot be done.

Ideally you don’t really want to disturb the existing fireproofing to expose the beam to find out, so checking the original plans is the fastest and safest way to determine whether you can extend your existing floor and it can withstand the new addition without having to put double posts at the point where the floor is extended.

While determining this is possible, the simplest way to expand an existing mezzanine floor is more simply to place a new floor on its own posts up tight against the existing floor and continue the same level so that it seems like a seamless flow from above, while it is actually a separate free standing structure alongside the original existing floor.
