A property inspection for assessment purposes occurs when an assessor visits your property to verify its characteristics and condition. These inspections are relatively rare, typically happening when properties are new, renovated significantly, or when assessment records need updating. Inspectors may measure buildings, note construction quality, count rooms, and assess overall condition. Property owners usually receive advance notice and should provide access, as refusal may result in estimated assessments. Regular reassessments often use aerial photography, building permits, and sales data rather than physical visits. If you've made significant improvements, an inspection may result in higher assessed value and taxes.
