SF Retail Corridor Snapshot: Union Square

1. Corridor at a glance

Vacancy is falling from the peak, but the corridor is still repricing.

• Union Square vacancy is roughly 15% as of May 2026, down from a peak of 22% in 2025 — against a 6.4% pre-pandemic baseline in Q4 2019 (ABC7 News, May 2, 2026).
• Trackers differ on the level, agree on direction: tightening.
  ~15% entering 2026, CoStar basis, on +31K SF trailing-12-month absorption ▼ from 16.5% YoY CoStar, 2026 23% Union Square/Post Street overall vacancy as recently as Q2 2025, Cushman & Wakefield basis SF Examiner, Aug 2025
• Union Square is the recovery laggard converging toward a healthy citywide market.

• The exception is the Powell Street block between the Square and Market, which carried an approximately 71% retail vacancy rate in 2025 (ABC7 News, May 2, 2026) and is now the explicit target of city recovery money (see Section 2).

Notable openings, 2025–2026

• Nintendo — first U.S. West Coast store; 9,000 SF over two floors at 331 Powell St in the Westin St. Francis building; opened May 2025 (The Real Deal, May 16, 2025).
• Bulgari — 206 Grant Ave, opened April 2025; Patek Philippe showroom — 259 Post St, opened May 2025; Shoe Palace — 301 Geary St, opened March 2025; John Varvatos — 58 Geary St, opened Aug 2, 2025; Just For Fun (toys) — 45 Kearny St, September 2025; Bang & Olufsen — 146 Geary St, October 2025 (all via SF Examiner, Aug 6, 2025).
• The RealReal — returned to Union Square with a redesigned two-story, 8,100 SF store, opened Feb 26, 2026, in the same location it previously vacated (The Real Deal, Feb 2, 2026).
• BAPE (A Bathing Ape) — first San Francisco store; 4,800 SF across three floors at 216 Stockton St, the former Dior men's space (SF Standard via MSN; RetailBoss, 2026).
• Zara — 40,000+ SF, four-story flagship at 400 Post St, opening 2026; nearly double its prior footprint (Axios, Apr 7, 2025). Uniqlo signed at 801 Market St, expected 2026, returning after a four-year absence (CBS News Bay Area).

Notable closures and reversals

Saks Fifth Avenue, 384 Post St, closed May 10, 2025 after 45 years, citing its Neiman Marcus integration (SF Standard, Apr 23, 2025). Zara's 250 Post St closure (January 2025) was a relocation, not an exit (Axios, Apr 7, 2025). The most important non-event: Macy's reversed its 2024 closure announcement — in November 2025 it partnered with TMG Partners to redevelop the 600,000 SF flagship property while the store stays open (SFist, Nov 4, 2025).

Rent direction: bifurcated

Prime frontage is holding; secondary frontage is where deals are getting done.

Foot traffic: recovering, led by events, evenings, and weekends

This is an evenings-weekends-tourism recovery, not yet an office-lunch-hour one — though office leasing hit 3.4M SF in Q1 2026 with the strongest net absorption since 2019 (Kidder Mathews Q1 2026 SF Office Report), which should feed weekday counts through 2026–27.

2. Leasing implications for a landlord holding space now

Active tenant categories are specific, not general. The 2025–26 signings cluster into five profiles: (1) experiential/collectible flagships (Nintendo, BAPE; Pop Mart anticipated at 200 Powell — SF Examiner, Aug 6, 2025); (2) luxury hard goods, especially watches and jewelry (Bulgari, Patek Philippe, Clicky Bezel at 50 Maiden Lane); (3) large-format value fashion re-anchoring (Zara doubling down, Uniqlo returning); (4) resale/recommerce (The RealReal returning to a space it had exited); (5) local specialty retail backfilling smaller units. A landlord's outreach list should look like this, not like 2019's.

There is real money on the table for deal-making. The SF Downtown Development Corp. launched a $25M Downtown Business Fund in April 2026: move-in grants up to $500,000, below-market loans up to $1M, and design assistance — initially targeting Powell Street between Union Square and Market and the Moscone corridor, prioritizing tenants committing to 3–7 year leases and explicitly funding the subdivision of large former-chain boxes into smaller independent footprints. Over 80 businesses and property owners expressed interest before launch (SF Standard, Apr 16, 2026). For a landlord with a large dark box near Powell, this materially changes the math on demising.

Short-term and pop-up structures are a proven on-ramp here, not a gimmick. The city/SF New Deal "Vacant to Vibrant" program places pop-ups on 3-month free-rent licenses (extendable 3 months) with grants up to $8,000; 21 storefronts have been activated since 2023, roughly 26 more are planned, and 11 participants have converted to long-term leases (SF New Deal, 2025; Axios, May 9, 2025). Conversion from pop-up to term lease is a documented pattern a landlord can underwrite. Published corridor-level data on average lease terms and percentage-rent prevalence does not exist; [landlord's own recent comps and LOI terms would be inserted here].

3. Re-merchandising angle: what mix is winning

The corridor's winning formula in 2025–26 pairs traffic-generating experiential anchors with high-margin luxury hard goods. Nintendo (May 2025) and BAPE (2026) create line-out-the-door moments; Bulgari, Patek Philippe, and independent watch retail on Maiden Lane monetize the adjacency — Maiden Lane also drew ~15,000 SF of tech office leasing across three buildings in July 2025 (SF Examiner, Aug 6, 2025), adding weekday bodies to a luxury micro-street. The RealReal's return signals resale now merits prime frontage. For a landlord re-merchandising a multi-tenant block here, the cited evidence supports: one experiential or collectible-driven anchor, luxury or specialty hard goods beside it, and short-term activation (via Vacant to Vibrant or the DDC fund) to keep secondary units lit while the anchor deal is made — rather than holding out for a single full-block credit tenant, the strategy Saks's exit and Macy's downsizing-in-place both argue against.
