“Dear PoPville,
I just got a shock receiving my property tax bill that I want to see if anyone else has experienced. I updated my Columbia Heights rowhouse kitchen and added a powder room last year and (stupidly, it turns out) applied for a building permit. The total cost was $40-50K. The permit triggered a supplemental assessment. The supplemental assessment increased the market value of my house by almost 50% (not counting land value), which I appealed and they adjusted it slightly.
Now I’m learning that just having the supplemental assessment not only increased my assessed value, it meant that I lost the 10% collar on my taxable assessment (i.e. rule that says assessment can only increase 10% a year) that is part of the homestead exemption (the other part is the deduction from value of around $70K). Since I bought a real dump of a house, that 10% a year limit meant my taxable assessment was only about 60% of the market assessment. Suddenly my property taxes have almost doubled. (more…)
