How are property taxes calculated on an Awendaw two-family?

Property taxes on an Awendaw two-family are calculated by multiplying the county's assessed value for the property by the millage rate that Charleston County and any applicable district set that year. A two-family or multi-unit property is generally assessed at the non-owner-occupied ratio unless the owner occupies one unit as their primary residence and applies for the lower owner-occupied classification. That classification can meaningfully change the tax bill even without any change in the property's market value. Brian Beatty can point an Awendaw owner to the county assessor's office to confirm the correct classification for a specific property.
