A riot of royal wedding celebrations could erupt around the borough in April after council chiefs pledged to sweep away the paperwork surrounding street parties.
Hammersmith and Fulham Council has stripped the process down to a simple two-page form amid fears that swathes of red tape would prevent people from holding their own community events.
Now all residents need to do to hold a party is make arrangements for diverting traffic and show they have the support of most of their neighbours.
It is hoped the new rules will inspire people around the borough to make the most of the marriage of Prince William and Kate Middleton on April 29, and on any occasions in the future when residents find a reason for a party.
Harry Phibbs, the council's community engagement leader, said: "Fetes, street parties and fairs should be fun, and everyone's energy needs to go into the fun part - not trawling through endless reams of guidance and dusty rules.
"With the royal wedding and the Queen's diamond jubilee due within months, this stripping away of bureaucracy has happened just in time and I look forward to seeing the bunting out and the parties in full flow."
Community groups up until now have had to apply for up to five separate licences before permission could be given to hold an event in the street.
Hammersmith resident Lotte Moore, 74, who lives by the river in Hammersmith Terrace, said: "I think it's a wonderful thing to make it easier because everyone should celebrate the royal wedding, especially at a time like this when everyone's so depressed.
"We tried to do it once but all the forms were so difficult that we gave up, so the simpler the better. This area is full of old people who will just want to put out a table and say hello to each other."
Alex Schniewind, of the Friends of South Park in Fulham, said: "As a resident I'd be happy to do it. It would be my first time but I know that many of the neighbours did it for the Queen's golden jubilee, and they talk about it all the time, so I think a lot of people would be excited."
Not everyone in the borough will take to the streets for the big wedding, however.
Dawn Lewis, who runs community group Keeping Youth Active in Shepherd's Bush and White City, said: "I like the royal family and I'm one of those people who will probably sit down in front of the TV and watch it, but I don't think many people round here will be bothered, to be honest. Because everyone is getting a day off after the weekend, I think more people will be thinking about going away."
The two-page form for local events can be filled out online or sent through the post to residents without internet access. To apply visit the council's street party page online.
