Finding beetles in house

Been finding these small black beetles around the house I am staying at, and am getting nervous that we might have carpet beetles. Hoping it is just a normal beetle but if not, will address. We live in the Denver, Colorado area.

Beetle is about half a centimeter or less long. (Measured!) The underside is also basically black, with a little bit of lighter brown around the legs. It does have wings, but we haven't seen any of them even attempt to fly.
