Valuation Office API

The REST Web Services API provides a REST interface to retrieve Valuation Office data in real time in relation to post-Revaluation Rating Authority areas. The post-Revaluation Rating Authority areas are Carlow, Dun Laoghaire-Rathdown, Fingal, Kildare, Kilkenny, Laois, Leitrim, Longford, Offaly, Roscommon, Sligo, South Dublin and Westmeath County Councils and Dublin City Council, Waterford City and County Council and Limerick City and County Council.

The fields you can filter by are County/Local Authority, Category, Use, Area Per Floor, Floor Use, Address, Publication Date, Nav Total, Rateable Valuation, Level, Car Park, Property Number and X IG & Y IG. The data can be returned in CSV, JSON or GeoJSON. An API query URL can also be generated for reuse.

The Data Resource Preview below returns an example of all commercial and industrial properties in the “Carlow County Council” Rating Authority area that fall under the category of “Office” in JSON format.

The Valuation Office provides this API with the understanding that it is not guaranteed to be complete and is subject to change. The API is a work in progress and will be expanded further. We welcome your feedback, please submit suggestions to opendata@valoff.ie
