The building tag should describe the type of building it is, not necessarily how it's used. For the Chehalis Tribal Law Enforcement bldg, building=public might be better along with a tag amenity=police. Similar with the Chehalis Tribal Wellness Center, I'd recommend building=yes + amenity=clinic. 

For the Chehalis Tribal Elders Center, you might want to add the tag amenity=community_centre + comunity_centre:for=senior.

I'll send you more info on OSM in a message. Let me know if you need help with fixing the tags.
