Assessment roll and property characteristic information is available for most parcels in Sonoma County
Roll data is available in our office or over the phone. Roll data includes basic assessment roll and assessee information about a property.
A Property Profile is a computer screen print that lists a variety of land, residential, value, agricultural, and commercial data for a single parcel; a copy of this print-out is available for purchase at our Customer Service counter.
Information on a Property Profile includes the parcel number, street address, assessee, and use code information, as well as quality/class rating, square footage, bed and bath count, parcel size and applicable agricultural preserve data.
The use code identifies the principal use of a property. Quality/Class ratings indicate the type of structure, quality of materials, and general shape of structures on a property.
Please note: Use codes are for assessment purposes only.
