Eating chunks of intact wall is unlikely, but surfaces like window sills are very risky because they constantly flake. That’s the nuance of lead mitigation. You can be completely compliant and safe for children with some lead paint on intact walls.

Any tenant can force their landlord to remove lead in those high risk areas (at landlords expense!) if there’s a young child but few renters know about this option.

Not true. Abatement is required. That is not the same as removal. Lead blocker paint or otherwise taking the surface out of contact is usual solution.

I don’t see what was untrue. Abatement still leaves lead paint on the walls. It’s a misconception that lead compliance means “no lead in house”.
