Pleasant Hill's housing stock varies enough that two similar looking lots can carry different assessments for real reasons, so the comparison has to be sale-for-sale, not street-for-street. Saskatchewan taxes residential property on 80 percent of assessed value, which is a separate step from whether the assessed value itself is accurate.
If the comparables genuinely do not support your number, the City of Saskatoon sets a formal appeal window each year that leads to the Board of Revision, and you will need documented comparable sales, not just a feeling that the number is too high, to make the case.
Assessment is a citywide statistical exercise, and it can miss a specific Pleasant Hill lot the same way it misses a renovation with no permit on file. Get your hand-reviewed valuation from Joel Dyck.
