Meteors that would burn up in Earth's atmosphere will strike the surface on Mars.
Shelters on Mars will need to be robust enough to take small meteor impacts.
Cold War-era structures (like Cheyenne Mountain) hardened against nuclear strikes would provide a perfect template for any human settlements on Mars.
Buried underground under reinforced concrete, with main habitation quarters set on springs to absorb any seismic shocks caused by impacts.
Besides, underground settlements would also provide protection from solar UV radiation and cosmic rays. Mars has no ozone layer to absorb UV, nor a significant magnetic field to shield againt solar flares.
