Allen 150 Fest Opens Vendor, Volunteer Applications for April Celebration

With Allen's 150th birthday party 27 days out, the city still has open slots for vendors, volunteers and performers at Allen 150 Fest, the free downtown celebration set for April 25 from 3 p.m. to 9 p.m. That covers three distinct ways to participate in the milestone without committing to the full six-hour event.

Parks & Recreation and the city's special-events teams are coordinating the festival, which will fill Downtown Allen with live music, food vendors, family activities, public art installations and community partner booths. Admission is free.

Vendors interested in a booth can access the application packet through cityofallen.org. The packet covers booth dimensions, any applicable fees, electrical access options and load-in and load-out windows. Required materials include a photo of the booth or product, a Texas sales tax permit for anyone selling goods, proof of insurance if required, and a completed electronic W-9. Anyone with large equipment, stage setups or sound needs should disclose those details upfront; oversized or noisy gear requires prior city approval and may be restricted given the finite footprint of the downtown festival site. Questions can go to coa@allentx.gov.

Space is genuinely limited. The city coordinates the event footprint with Allen Police, Parks staff and public-works crews, who will handle street closures and traffic management on the day. Early applicants get priority in the site-map process, which locks in tent placement, power connections and load-in sequencing.

Volunteers can fill roles including set-up and teardown, wayfinding, hydration station staffing, children's activity monitoring and vendor support. Performers should submit a demo reel or past-event references as part of a programming application; organizers are building a curated stage schedule designed to stay family-appropriate across all six hours.

ADA access is built into the event plan through the same safety and logistics coordination handling street closures. Anyone needing special accommodations should contact the events team before the site plan is finalized.

All application materials and volunteer sign-up forms are posted on the City of Allen event page. Reach the events team directly at coa@allentx.gov or through the Allen 150 Fest contact listed on the city calendar at cityofallen.org.
