About the Building
Gridiron is a 2018 Pioneer Square building that keeps the historic Johnson Plumbing facade and builds a contemporary residential tower behind and above it, an approach designed by Hewitt for Daniels Real Estate with Chinn Construction as builder.
For a 107-home building the amenity program is deliberately social: concierge and package service, a penthouse club, rooftop terrace with grills, fitness center, coworking, wine storage, bike storage and a pet lounge with dog wash. Parking is secured but available for qualifying residences only, which matters in a neighborhood where street parking is scarce.

Important
No Rental Cap ≠ Short-Term Rental
A building can allow an unlimited number of owners to lease their residences while still requiring a 30-day, three-month, six-month, twelve-month, or longer minimum lease. Rental-cap percentage and minimum lease duration are separate rules and should always be reviewed independently.
