Special Assessment

Special assessments are not part of your real estate tax, but are included as a separate item on the real estate tax bill. Special assessments may include, but are not limited to, items such as:
ditch assessments
   - improvement levies (such as street paving, curb repair/replacement, lighting districts, sidewalks, and sewer or water lines)
   - nuisance abatements (such as noxious weed, litter or trash removal, or building board-up costs)

The Auditor is required by law to keep an accounting of these special assessments, to place them on the tax duplicate as separate items and to return the money collected to the city, village, township or county office which levied the assessment.

Questions regarding special assessments may be directed to 513-887-3154 or by emailing our office at specials@butlercountyohio.org

Future Assessments
All future or pending assessments can be searched online through the Butler County Auditor's website. You may access the directory for the future or pending special assessments by using the Auditor's Property Search engine. The search engine can be accessed by clicking on Property Search in the menu above or hovering your computer mouse over Property Search and using the dropdown menu:

Search your subject property by parcel number, owner or address. Once selected and while on the main "profile" page you will see a link on the right hand side of the profile page labeled "Pending Specials'. This link will take you to the directory which is sorted by taxing authority.

Helpful search instructions are located within this directory in a file named "1_Read Me". Also note, some taxing authorities, such as Butler County Water and Sewer and Southwest Regional Water District have the ability to cross jurisdictions. Folders for these types of entities are noted by adding "multi district" to the directory title. Please note that you may need to check these "multi district" entities with every search you perform.

The Pending Special Assessment file is updated nightly. The link for the Pending Special Assessment Directory is:
