Who hears it, and where it goes

Your appeal is decided by the Lancaster County Board of Assessment Appeals.

Where to file

Lancaster County Board of Assessment Appeals
Lancaster County Assessment Office
150 North Queen Street, Suite 310
Lancaster, PA 17603

Lancaster County reassessed every property for the 2027 tax year, so the appeals filed this year were reassessment appeals. Its next annual appeal is for the 2028 tax year and is filed in 2027; the county says more information will be available in early 2027.

Filed by mail or in person during office hours (the building entrance is on Chestnut Street).

What your assessed value means here

Pennsylvania — assessed at a base-year value; the STEB Common Level Ratio for your county is about 50% of current market. Confirm the ratio on your notice (53 Pa.C.S. §8854).

Lancaster County's common level ratio is drawn from the 2025 CLR (2024 sales data; effective 7/1/2026–6/30/2027) table — the same figure the app uses to compare your assessment to current market value.

Can the board raise your assessment?

Yes. The Lancaster County Board of Assessment Appeals can raise your assessment on your own appeal, not only lower it. That is the risk you take by filing, and it is why the case has to be worth making before you file it.

What a board actually weighs

The Lancaster County Board of Assessment Appeals decides what your property was worth on the valuation date, so recent comparable sales carry the case, not the size of the bill. The Pennsylvania guide covers the evidence.
