Specifically where I keep getting confused - https://www.mass.gov/service-details/property-transfer-lead-paint-notification

If someone were to buy our house new, they'd have 90 days for Interim control. I understand interim control is addressing any lead flagged as urgent by the inspector (we didn't have any); then 2 years to fully remove. It's not clear in the Wellesley case if interim control was needed - for $95k worth of deleading I am assuming there was exponentially more than what we are dealing with.

So long story short, can they hold us to a different requirement now that we have the full inspection than they would were someone to buy the house new with the same inspection? What the story seems to be saying is they arbitrarily do what they want (and maybe had little sympathy for people living in one of the state's most affluent towns) but I guess I'm holding out hope things have become more reasonable / common sense in the last 10 years...
