Gary Numan currently lives in Los Angeles, California. He moved there with his family in October 2012 and resides in a large house that has been described as castle-like, featuring unique architectural details including vaulted ceilings and secret staircases. Despite the grandeur of his home, he maintains a very normal family life with his wife and three daughters. His wife Gemma fell in love with the house from the start, and they have enjoyed living there for many years.

In addition, in 2023 Gary Numan was reported to be fixing up a new house, but the primary confirmed long-term residence remains the Los Angeles property where his family lives.

There is also mention that at times he spends a few days in Scotland, but this appears to be temporary rather than his main residence.

In summary, Gary Numan's main residence is in Los Angeles, California, USA, where he lives with his family, having moved there over a decade ago from the UK.
