The newly-formed Asker Municipality was made part of Viken County immediately following the 2020 merge.

However, Viken dissolved on 1 January 2024, returning Asker (with the addition of Røyken and Hurum) to the county of Akershus.

Its main parts are Asker, Gullhella, Vollen, Vettre, Blakstad, Bleiker, Borgen, Drengsrud, Dikemark, Vardåsen, Engelsrud, Holmen, Høn, Hvalstad, Billingstad, Nesøya, Nesbru, and Heggedal.

There are many hiking/ sightseeing spots around Asker; such as Semsvannet lake[9] and Drengsrud cultural path[10] around the area.

A tentative agreement was reached and on 16 June 2016 the Municipal Council of Røyken approved the merger with Asker and Hurum with 24 votes for and 3 against.

Although Asker is principally a rural municipality, the expansion of Oslo has resulted in its becoming an affluent suburb.

The neo-Gothic red brick church was built in 1879 based upon designs by architect Jacob Wilhelm Nordan.

The statue of Crown Princess Märtha in front of the church was designed by sculptor Dyre Vaa in 1957.

[18] On 31 July 2016 it was reported that the hull of Maud had been raised to the surface and placed on a barge in preparation for shipment to Norway.

[19] In August 2017 Maud began the journey back to Norway; she was towed through the Northwest Passage.

[20][21] Maud arrived in Bergen on 6 August 2018, finally returning to Norway nearly a century after her departure with Amundsen.
