Do Liens Accumulate?

[Taylor Herman]

Hello BP,

In doing my due diligence on a few properties today, I noticed that a particular homeowner had multiple water and sewer liens for differing amounts. My question is, are the lien amounts cumulative? That is, if they have a lien amount of let's say $350 in 2012, then $550 in 2015, does that mean they now have a total lien amount of $900, or is the $550 in 2015 an accumulation of all unpaid liens since that $350 in 2012?

Thanks!
