[1] The club continued in the Combination with varying degrees of success including an FA Cup second round appearance, losing to Gateshead, in 1947-48 and a Lancashire FA Challenge Trophy final victory in 1951–52, but by 1970 it was decided that a change was needed so for the 1970–71 season the club left the Combination to join the Northern Premier League.

City again reached the second round of the FA Cup in 1972–73, losing 2–1 at Notts County and won the Lancashire FA Challenge Trophy for a sixth time in 1974–75, but after finishing seventeenth in 1981–82 the club resigned from the league and dropped into the North West Counties League when financial difficulties forced them to fold and reform.

A first ever relegation followed three years later and despite only finishing thirteenth in 1986–87, City were accepted into the newly formed Division One of the Northern Premier League thanks to in no small part to ground standard and support.

Two consecutive Northern Premier League Challenge Cup wins followed in 1999–2000 and 2000–01 under Tony Hesketh and after finishing eighth in 2003–04 the club were placed in the newly established Conference North.

More financial problems led to the club folding at the end of the 2006–07 season though, suffering a 10-point deduction for going into administration and finishing bottom of the league with one point.

Both Peacock and Sinclair left the club in September 2015, and City appointed ex player Phil Brown as manager.

He led the team to a top six finish and a narrow penalties defeat in the Lancashire FA Challenge Trophy final to Chorley.

The ground has seen many changes since those early days and was renovated in the 1970s when the original main grandstand and then the social club were both destroyed by fire.

Next to the main stand are the players and officials changing facilities, a supporters' bar named Netbusters, the directors lounge, toilets and The Dolly's Diner refreshments kiosk.

Opposite the Main Stand is the Long Side, an open terrace that also plays host to a second supporters bar, a raised sponsors hospitality lounge and the dugouts.

However, after financial difficulties had led to relegation and reformation in 2008, the club adopted a raffle sponsorship arrangement with several local businesses entering an annual draw with the winner becoming first team shirt sponsor.

This carried on successfully for ten years until they won promotion in 2016-17 and Lancaster teamed up with local media group and radio station Heart North Lancashire and Cumbria signing a three-year shirt sponsorship deal for the start of the 2017–18 season.

Lancaster City have in the past had a ladies team that played in the Lancashire FA Women's County League but they folded at the end of the 2015–16 season.

The ladies team reformed for the start of the 2022–23 season and were admitted into the Lancashire FA Women's County League, competing in Division One North/West.
