Should I be expected to wear a mask around company visiting for 10 days?

I live with my mom. I live in Oregon so its a high transmission area. My mom is leaving to Alaska on the 20th and my sister, brother in law, and nephew are all staying with me for 10 days because my mom doesn’t trust me alone. Should I be expected to wear a mask and social distance around them? I’m fully vaccinated but they are all unvaccinated.
