House Party 4: Down to the Last Minute is a 2001 American direct-to-video comedy film.

Jon-Jon sees a ripe opportunity for a major party when he snags the job house-sitting for his rich Uncle Charles.

The mansion comes with a platinum colored Mercedes-Benz 430 and, although Uncle Charles has told him not to drive the car or have people over, Jon-Jon wastes no time in doing both; Jon-Jon is not only having an "entertainment party", but he's auditioning his hip-hop band (IMx) for a record executive.

When Jon-Jon finds out his uncle is coming home earlier than announced, he has to race against time to try to put everything back the way he found it.

The next film in the series, House Party: Tonight's the Night starring Tequan Richmond and Zac Goodspeed, was released direct to DVD on July 23, 2013; that film is a direct continuation of House Party 3, and disregards the events of House Party 4.
