The public can now access the Urban Redevelopment Authority (URA) database for free, after a revamp to make it easier for users to retrieve information about buildings and properties.

Previously, buyers or lessees of a property wanting to find out information like its approved use, storey height or history of renovation works had to sieve through a "cumbersome" database manually, said National Development Minister Khaw Boon Wan in a blog post on Wednesday.

To simplify the process, the URA has launched a new map-based application, which uses a technology called Geographic Information System.

Through the revamped database, users only need to click on a building, or type in an address.

Relevant information will then pop up, including decisions on any new building erections or addition or alteration to structures or change of use.

"With this new self-help online register, users will get the data they need anytime, and anywhere," said Mr Khaw.

While a $30 processing fee was charged for each search under the old database, URA has decided to make access to the new one free.

"The URA will continue to tap on technology to make information more accessible to the public," Mr Khaw said, adding that the URA plans to apply the same technology to enquiries on development charge rates soon.
