Union Street's New Storefronts Are Following One Old Rule

On September 11, a line formed outside 1838 Union Street for a restaurant that already knew the address. Kaiyō Handroll Bar opened that Friday in the same Cow Hollow storefront where founder John Park first launched Kaiyō back in September 2018, before the pandemic forced him to close it. At another Union Street address, a different storefront story ended that same week. Butter & Crumble, the North Beach bakery known for lines that wrap around the block, announced it was walking away from its long-planned second location at 301 Union Street. The reason had nothing to do with demand and everything to do with a wall.

Two storefronts, two outcomes, one street. Their contrast points to a practical detail about Union Street that drive-by observations about a "hot corridor" can miss.

The address that already knew how to be a restaurant

Kaiyō Handroll Bar is the third project from Park's Brick by Brick Hospitality Group, joining the original Kaiyō Restaurant and its rooftop bar near Oracle Park. Rather than opening a new dining room from scratch, Park and partners Danny Louie and Suzanne Miller returned to the exact Union Street shell that had sat dark for two years and reworked it into something narrower in scope: a cart-to-table Nikkei hand roll bar, built around a lomo saltado roll made with A5 wagyu, according to reporting from the San Francisco Examiner. The space still functions as one restaurant kitchen. Nothing about the building itself needed to change.

That detail matters more than it sounds. Reopening inside that shell is closer to a renovation than a ground-up build. Park's team wasn't fighting the building. They were reusing it.

Other Union Street storefronts, a similar playbook

Two other Union Street storefronts followed a similar pattern. Frankie's on the Park, a Chicago-based fashion boutique making its first Bay Area move, opened at 1843 Union Street with a grand opening running August 14 through 16. Owner Tahlia Bliss picked the block in part because it sits within walking distance of two all-girls schools, giving the shop a built-in customer base of students and families passing by on foot. The space had already been operating as retail. Bliss's team walked into a shell built for exactly what they wanted to do with it.

Franko & Friends planned to bring its Sausalito coffeehouse concept across the bay into 2055B Union Street, the former home of Joyride Pizza. Owner Iryna Nevozhai, who runs Franko & Co. in Sausalito, had targeted an early September opening for a roughly 1,600-square-foot space that would start as a coffee and pastry counter by day and shift to wine service by night, according to WhatNow's original reporting. Like Kaiyō and Frankie's, Franko & Friends planned to use a footprint that already functioned as a single food-and-beverage tenant. No lots to join. No walls to explain to an inspector.

What took down the Cake Shop

Butter & Crumble's plan for 301 Union Street was never a simple lease signing. Owner Sophie Smith had spent close to a year and tens of thousands of dollars on architects and preliminary construction work, training staff for new management roles in what she described as an 1,800-square-foot commercial space. The property had been used as a single space for years, and Smith said she was told by both the landlord and a city department that its two-lot history wouldn't be an obstacle.

It was. In July, the city's Department of Building Inspection found that a previous permit for the site actually showed a wall separating the two lots, with no record that the wall had ever been legally removed. According to Headtopics, joining two commercial lots into one isn't a paperwork formality. It requires new rollup doors, two separate evacuation routes, and fire sprinklers on both sides of the building, on top of the zoning questions the merger raises. Smith announced the cancellation the week of September 11, writing that after weeks of exploring options, "we came to the conclusion that 301 Union St. is just not a viable space for us."

San Francisco's Office of Small Business told reporters it was sorry for the setback and would keep supporting Smith as she looks for a new location. That's a real gesture, and it doesn't undo seven months of architectural drawings built around an address that turned out to be two addresses wearing one storefront.

The lot-line issue behind a canceled Union Street location

Compare all four Union Street storefronts and a pattern emerges. Kaiyō and Frankie's on the Park moved into spaces that had already been occupied as single commercial units for their intended uses; Franko & Friends planned to do the same. Kaiyō and Frankie's opened on schedule or close to it; Franko & Friends had targeted a September opening. Butter & Crumble's Cake Shop tried to do something none of the others attempted: combine two separately platted lots into one continuous retail floor. That single difference, not concept, not funding, not demand, is what separated an opening week from a canceled one.

Union Street's commercial buildings carry over a century of small, individually subdivided storefronts, and that history doesn't show up on a rent listing. It shows up in a Department of Building Inspection file from decades ago, the kind of record that only surfaces once someone tries to treat two lots as one. For a bakery with 84,000 Instagram followers and a landlord's verbal assurance, that record was enough to end the project.

Reported status of the four storefronts

Here is what had been reported about the four storefronts:

• Kaiyō Handroll Bar is serving nightly at 1838 Union Street, with tableside handroll carts and a cocktail program from Danny Louie.
• Frankie's on the Park has been open at 1843 Union Street since mid-August, carrying girls' and juniors' fashion.
• Franko & Friends had targeted a September opening at 2055B Union Street, bringing Sausalito's coffee-and-pastry menu across the bay with wine service added for evenings.
• 301 Union Street is back on the market for a new tenant, its two-lot history now a matter of public record for whoever leases it next.

None of this changes what Union Street looks like from the sidewalk. It changes what a new operator needs to check before signing anything at an address on this block, and it's a detail that only shows up once you've watched it happen twice in the same month.

Sage keeps a close eye on what opens, what stalls, and why on the streets our clients call home, because those details often explain more about a building than the square footage ever will. If you're curious what a specific Union Street or Cow Hollow address has been through before it became what it is today, Sage Real Estate can help you find out.
