For those who are owners of structures in commercial or industrial districts, the regulations have become stricter. The general terms will include all structures, but things like unreinforced masonry buildings seismic retrofit are specific and special to older installations. And they will more likely than not badly need this for protection in case the unfortunate happens.
In many places in this country, things like insurance and operational permits or licenses to operate hinge on your having this type of thing done. In fact you might really go nowhere when your masonry building does not have the retrofit. And for the money your occupants, which could include yourself will have more worry free sleep.
Earthquakes may be rare or something you think may happen somewhere else. But when they do, among the first things to collapse will be degrading masonry walls and pillars. You might have done up the foundation and added more buttress materials or support to the things that hold your building up, but a really dedicated retrofit is more effective.
Engineers and experts in the trade have studied how this thing could be done. And these days, the science and tech are really excellent. At the very least, you will have more time to evacuate the premises when the rolling waves of moving crust start to destroy even the mightiest buildings like flimsy shanties.
Many times, only earthquake survivors, may be the only ones who appreciate the need for the retrofit. Your issue may be because an insurance firm will cut down on the premium when you have had the seismic service done. Even so, this is a good enough reason to get the job done, and government adds more importance by setting their licensing standards on such services.
You could study how the work might be available through your budget. This is mostly the operative issue here, and in terms of dollars and cents, an earthquake demolishing your old building may be convincing. Care for occupants is also attendant on their being able to survive when they live in your unit, and that will make them stay longer and appreciate your building.
Masonry is not a proven factor that could make buildings withstand earthquake. To put it lightly but truthfully, bricks in masonry turn out into rubble without fail during strong quakes. The government and their experts plus experts in the private sector all know this now and require there to be at least some mitigation if you have this on your structure.
This mitigation is directed towards earthquakes, because the material is good enough to withstand the harshest storms. Most of the work that is done will be by firms specializing in this process of buttressing or redoing a bit of the brick and mortar to make it stronger. The strongest of these things are going to be puny when it comes to strong temblors, as mentioned, and being prepared always helps in this sense, especially when there is actually little time given for safety during these events.
