What are Philadelphia's block party rules?
The applicant must live on the block and apply at least 21 days ahead. Seventy-five percent of households on the affected blocks must sign off. The fee is $25 if you apply three weeks ahead, otherwise $60. 'T' streets need a petition, and the police district reviews the request.
Those are the city's block party page rules as found for this site. Confirm them with the city before you rely on them, because details can change and a specific street may have its own conditions.
Notice what is absent: the city's block party page, as sourced for this site, does not say how many toilets to rent. That is a question for you, your neighbors and the provider. The block party and street festival guide gets into it.
How is a street festival different from a block party?
A street festival sponsored by a business or organization, or held on a major arterial or commercial corridor, applies to the Department of Streets for a festival street closure. It is not organized by a resident of the block, and it is bigger. The special event application also asks for the total number of portable restrooms.
For anything that counts as a parade, festival, run or regatta, the Office of Special Events is the city's one-stop shop. A public event also needs a Department of Public Health permit for portable chemical toilets, at $50 per location, and about 10 to 14 days to receive it.
Plan the toilet order around those dates. The permit takes more than a week, the closure takes longer, and providers confirm units for a date only when they have some free.
Where do units go on a narrow rowhouse block?
On the road inside the closure if the city and the provider agree, near the middle of the party, with a gap kept for the service truck. Keep units off pavements, driveways and doorways. Ask the provider whether the closed street gives the truck room to reach and turn.
Philadelphia's rowhouses sit on narrow lots along gridiron streets, and a delivery truck has little room. On a closed block the road is the widest space available, but the truck needs to get in before cars are blocked and out before the barriers go away.
A pavement placement is a different matter: it narrows the walkway and needs the owner's or the city's permission. The rowhouse page covers pavement and driveway placement for jobs. For a party, the road inside the closure is the natural place.
