"Putting $8,000 or $10,000 into the city coffers before I even sell one item is just a huge hurdle." That is Councilmember Urban Carmel, as reported by the Mill Valley Briefing. He was describing what prospective business owners had told him about opening downtown under Mill Valley's old permit rules.
The hurdle has been lowered since then. Downtown Mill Valley spent the summer looking like a street in retreat, with papered windows on Throckmorton and dark storefronts on Miller. The windows gave the wrong impression. Most of the dark spaces already had confirmed tenants, and by mid-October several of them are open.
Ninety-Three Storefronts, Sixteen Dark, Seven Truly Empty
In the week before August 16, 2026, the Mill Valley Briefing walked every downtown block and counted 93 street-level storefronts. Sixteen had no open business. Nine of those sixteen already had a confirmed tenant that had not opened yet. That left seven with nothing lined up.
The Briefing's math gives two vacancy figures. Counting only the seven unclaimed spaces, downtown's real vacancy rate was 7.5% in August 2026. Cushman and Wakefield put the national retail vacancy rate at 6% in the second quarter of 2026 and the historical average at 7.4%, so downtown was running close to normal. Adding the nine spaces under renovation pushes the figure to 17.2%, because nobody can walk into those either.
The gap between 7.5% and 17.2% is made up of tenants that were confirmed but not yet open. Some of those spaces had been dark a long time. The Briefing noted that 57 and 60 Throckmorton had sat empty for years before new tenants were confirmed.
Where the Claimed Spaces Stand on October 12
Here is the latest public status of the named shop, food, workspace and gallery tenants, eight weeks after the count:
| Address | Tenant | What it is | Latest public status |
|---|---|---|---|
| 17 Throckmorton Ave. | Lima Nikkei | Peruvian-Japanese restaurant | Open and taking reservations by late September |
| 12 Miller Ave. | Milkweed | Natural clothing, toys and gear for babies and children | Grand opening held Sept. 12 |
| 38 Miller Ave. | Dorado 806 | Gallery exhibition | "Lesser Known Monsters" runs Sept. 18 to Oct. 17 |
| 55 Sunnyside Ave. | Wonderhouse | Family co-working in the former Post Office | Site still reads "Coming Soon" |
| 60 Throckmorton Ave. | Treehouse MV | Retail and co-working in the old Bank of America | Not open as of the August count |
| Miller Ave., former Gravity Tavern | Delphine | Coastal Mediterranean, per an April report | Preparing to open as of August |
| Miller Ave., former Urban Remedy | Bootjack | Bakery | Named as incoming tenant in August |
| Beside 55 Throckmorton | Indoorra | Kitchen systems retailer | Named as incoming tenant in August |
The two openings that matter most are at opposite ends of the shopping street, and both have regular hours. Milkweed says its doors are open at 12 Miller. The Mill Valley Chamber listed its grand opening for the morning of Saturday, September 12. Dorado 806 is a different kind of tenant. The Briefing described it as an art exhibition, not a permanent shop, and the gallery's own page says hours after the second week of October are subject to change. That makes the next few days the reliable window to see "Lesser Known Monsters" at 38 Miller.
The open questions are on Miller Avenue. An April 30, 2026 report in Travel And Tour World, republishing a release, named Berk and Betul Kinalilar, the owners of Troya, as Delphine's operators. It forecast a summer 2026 opening. In mid-August the Briefing still described Delphine as preparing to open in the former Gravity Tavern. No public update has surfaced since.
The Corner That Has Been a Restaurant Since 1947
Lima Nikkei is the opening that changes how downtown feels after dark. Its address, 17 Throckmorton, has more history than any other space on the list.
According to the Chamber's Mapping MV History series, El Paseo operated continuously from 1947. Sammy Hagar and Tyler Florence opened a steakhouse version in 2011, and Hagar owned it until it closed in 2018. Ki Yong Choi's group took over in 2019, opened Paseo Bistro on December 10, 2020, and closed it on December 20, 2025 after five years.
Counting from that closing to the late-September reservations, the space was dark for about nine months. For one of downtown's best-known dining rooms, that is a short gap.
Lima Nikkei is the new tenant. Founder and owner Edwin Sandoval describes the food as Peruvian-Japanese. The menu covers sushi, tiradito, ceviche, robata and katsu, plus cocktails. It is open for dinner only, from 4 to 9 p.m. Sunday through Thursday and until 10 p.m. on Friday and Saturday. A September 4, 2026 restaurant guide from Local Getaways listed it as a new Peruvian-fusion restaurant in the former Paseo Bistro space.
Why the Pipeline Moved This Year
The quick turnover at 17 Throckmorton and the cluster of incoming tenants fit with a series of changes at City Hall. The Briefing traced the sequence. In November, an ordinance removed new parking requirements for most changes of use under 5,000 square feet. In April, the council passed a zoning rewrite that took effect May 20, 2026. For most ground-floor businesses, it replaced the Conditional Use Permit with a faster Administrative Use Permit.
The fees changed as well:
- Administrative Use Permit: $1,954, a new tier for uses that used to need the full process
- Standard use permit: cut to $5,647, according to Senior Planner Daisy Allen as quoted by the Briefing, which gives the old fee as $7,339; the Chamber's April report puts the old fee at $7,389
- Temporary Use Permit: also set at $1,954 under the April 20, 2026 council action, per the City of Mill Valley, which describes the Conditional Use Permit reduction as 24%
Carmel's $8,000 to $10,000 figure was the cost of opening the old way. The new administrative fee is about a fifth of that. The city also says some food and restaurant uses can now open in most commercial areas with no use permit at all. The Chamber covered the package in April under the headline that Mill Valley had "moved with alacrity."
No public record shows that Lima Nikkei, Delphine or Bootjack used the new administrative route. Some restaurant uses may not need a permit at all now. The rules got cheaper in May, and by August nine dark storefronts had confirmed tenants.
The Seven Windows With No Name Yet
Cheaper permits may help account for the incoming tenants. They do not account for the spaces still waiting. As of the August count, these storefronts had no announced tenant:
- 23 Sunnyside, formerly Kim Eagles-Smith Gallery, with work underway inside
- 77 Throckmorton, formerly Mili
- 88 Throckmorton, formerly Peet's Coffee
- 108 Throckmorton, formerly Chandler Gallery
- 111 Throckmorton, formerly Two Neat
- 153 Throckmorton, formerly Oska
- 32 Miller Ave.
Five of the seven are on Throckmorton, the street most people think of as downtown. That puts the remaining vacancies right on the main walking route, while most of the new openings are on Miller and the south end of Throckmorton.
Jim Welte, executive director of the Mill Valley Chamber of Commerce, gave the Briefing a reason that has nothing to do with permits. "Developers who have money to purchase, but don't yet have a vision for their space" are part of what keeps some corners dark, he said. A lower fee helps a tenant who already has a plan. It doesn't help an owner who doesn't have one yet.
A Film Festival Week on a Half-Full Street
The 49th Mill Valley Film Festival ran October 1 through 11, 2026, so the first big test of the new downtown has just ended. The Sequoia Cinema at 25 Throckmorton was one of five festival venues. The Outdoor Art Club at 1 West Blithedale was another. According to the Marin Independent Journal, the festival opened with "Wild Horse Nine," and opening-night photos showed the screening at the Sequoia and the gathering at the Outdoor Art Club. The festival's own guide listed a change for this year. The Outdoor Art Club patio was open to the public, with Mill Valley Market sandwiches and a happy hour.
That meant festival crowds walked out of the Sequoia onto the same block as Lima Nikkei at 17 Throckmorton. A year ago, the restaurant on that corner was in its final season as Paseo Bistro.
Some new food in town opened outside downtown entirely. The Marin IJ reported in August that Tartine and Cholita Linda opened at Strawberry Village. Mendocino Farms opened in the Alto Center at 745 East Blithedale, the IJ reported in June.
The Briefing has said it will keep its downtown storefront tracker updated as spaces open and tenants confirm. Next spring, compare it against the August count. The question is whether the 17.2% falls toward 7.5% as Wonderhouse, Treehouse MV, Delphine, Bootjack and Indoorra open, or whether new vacancies on Throckmorton take their place.
