Riverside's History Is Mostly Behind Scaffolding This Fall. Here's Where the Doors Are Actually Open.

"Evacuated on May 23, 1942, Sat. 7 a.m." Harold Harada wrote those words on the wall of an upper-floor room in his family's house on Lemon Street. They are still there. Nobody outside the project can go in and read them this fall. The Museum of Riverside lists Harada House as "currently closed for rehabilitation."

Harada House isn't the only closure. Riverside's best-known history buildings are all on long rehabilitation timelines at once. For October and November 2026, the city's past is open in three smaller places: one Victorian house museum, one downtown storefront, and a set of recurring street-corner pop-ups. If you plan a history weekend around the famous names, you'll find locked doors. Plan around these three and you'll find a full calendar.

The Grant That Starts a Long Clock on Lemon Street

On Sept. 1, 2026, the city announced a $60,000 grant to the Museum of Riverside for Harada House. It comes from Asian & Pacific Islander Americans in Historic Preservation through its Placekeepers' Fund, a program backed by the Mellon Foundation's Humanities in Place initiative. The award was one of 14 chosen nationally from a pool of more than sixty qualified applicants.

The money pays for the first construction phase: foundation work and structural stabilization. According to the city's release, work "is slated to begin next winter" and is expected to take "at least two years due to the complex nature of the technical preservation challenges." That covers the stabilization phase only. Interpretive exhibits and public access come after it.

There's a reason this house gets national attention. It became a National Historic Landmark in 1990 because of People of the State of California v. Jukichi Harada et al., a case heard from 1916 to 1918. In it, the Superior Court upheld the 14th Amendment rights of the American-born Harada children against California's 1913 Alien Land Law. The city describes the case as the first test in the United States of the constitutionality of those laws. The state declared the house a California historic landmark in 2022. The Press-Enterprise describes the two-story 1884 home as largely empty, with faded wallpaper, plywood on the walls and a shaky brick foundation.

Behind the scenes, the project has picked up speed. In November 2025, the museum reported that design work had restarted with a new team, K+R Design. It also said salvaged 1880s rooms from the former Robinson House are planned as part of a future Harada House Interpretive Center. Holden Films is set to make a full-length documentary about the house. The museum says it will post construction updates on its website once work begins.

Three Closures, Three Different Timelines

Harada House is one of three major closures, and each one is on its own schedule. Here's the current status of each.

• Museum of Riverside, downtown main site. Closed for rehabilitation and expansion. The museum is preparing exhibitions and programs for a spring 2028 reopening.
• Harada House, 3356 Lemon St. Closed. Stabilization work is slated to begin "next winter" and to run at least two years.
• Trujillo Adobe, 3669 Center St. Closed. RivCoParks reports roof failure and partial wall collapse. It places the site in a 2026–2027 planning phase, with construction in 2028–2029. The National Park Service says the site isn't open to the public during planning and environmental review, and its page gives 2030 for the restoration project. The two agencies publish different target years, so neither should be treated as final.

With all three closed, the open sites carry the whole calendar.

Heritage House Is Doing the Work of an Entire Museum System

The city announced in September that every Museum of Riverside site except Heritage House is temporarily closed. The museum has used its one open building well. Its education staff have added after-dark insect and spider hunts in the gardens, a World Snake Day celebration and a hands-on STEAM school program about bringing water to early Riverside's citrus groves.

The basics: Heritage House is open Friday through Sunday, noon to 4 p.m. Tours start at noon, 1:15, 2:15 and 3:15. Booking is free, with a suggested donation of $5 per person.

This fall's program is built around one theme: how Victorians handled death, mourning and the dangers hidden in everyday objects.

The Dark Carnival is the October 17 highlight. The museum lists "Tea with the Undertaker," a mermaid, cure-alls, tarot, oddities and a free activity. The Eventbrite listing says the carnival is free. The museum's event page also suggests booking a house tour to see the mourning displays inside, so reserve a tour slot if you want to go in. Dying for Art covers the hazards in Victorian art supplies and includes an activity and house tours.

Main Street Is Where the Walking Tours Begin

Downtown, the second open door is the Mission Inn Foundation & Museum at 3598 Main St. The Foundation celebrated its return to that address with an opening weekend on Nov. 15–16, 2025. That weekend featured its "On Peace and Friendship" exhibit, retail items and a starting point for downtown walking and specialty tours.

Its tours still leave from there. The Foundation lists a daily Historic Downtown Walking Tour. Its booking portal currently shows that tour from $21.20. The Foundation's tour listings also include Architectural, Historic Churches, Courthouse/Murals/Heroes, Mt. Rubidoux, Olivewood Cemetery and Evergreen Cemetery tours. Storefront hours were reported in late 2025, and it's best to confirm them directly before you go.

The Foundation's tours and the hotel's tours are now run separately. In November 2025, the Press-Enterprise reported that the Foundation no longer guides tours inside the hotel. The Mission Inn Hotel & Spa offers its own guided historic tours throughout the year and takes bookings through OpenTable. To walk the streets with a docent, start at the Foundation on Main Street. To see inside the hotel, book with the hotel.

The third open door is outdoors. The Museum of Riverside sets up at Riverside Artswalk on the first Thursday of each month at Main Street and University Avenue. Starting in October, it will also appear every first Sunday through May at Main Street and Mission Inn Avenue, with programs on fossils, insects and local history. On the museum's busiest outreach weekends, the museum without a building is on a downtown corner.

Check the Doors Open List Before October 24

Doors Open Riverside, the event that opens historic buildings that are usually closed to the public, is set for Saturday, Oct. 24, 2026, from 1 to 5 p.m. It's free. The information center is at the Mission Inn Foundation & Museum, 3598 Main St. The city hosts it with the Riverside Downtown Partnership and the Mission Inn Museum and Foundation. It won the 2019 Governor's Historic Preservation Award.

The roster on the city's event page has some open questions. A heading on the page says the "full list of participating historic buildings and tour hours" is "coming soon," and a 14-site list appears under it. That list matches the 2025 lineup exactly, special tour hours included. It includes Harada House and Trujillo Adobe, which are both officially closed. It also gives the Mission Inn Foundation's address as 3750 Market St., although the page names 3598 Main St. as the information center. The Riverside Downtown Partnership's April 8, 2026 board minutes record only "initial planning" for the event.

So the list on the page today is best read as last year's lineup. The final 2026 roster may look different, especially for the two closed sites. Check the city page again in the week before the event and plan your route from the updated list.

October 24 also has a scheduling overlap. Dying for Art runs at Heritage House from noon to 4 p.m., and Doors Open runs downtown from 1 to 5 p.m. One workable plan is a noon tour at Heritage House, then the drive downtown to pick up a map at 3598 Main St. while the Doors Open buildings still have most of the afternoon left. That's one afternoon covering two of the three open doors, on the busiest history day of the fall.

Harada House, Trujillo Adobe and the downtown Museum of Riverside all have long timelines ahead of them. Jacqueline Johnson follows those restoration timelines and the history calendar so Riverside homeowners can plan their weekends around what's actually open. If you have questions about Riverside's historic neighborhoods, or what a restoration project nearby might mean for your street, schedule a free consultation.
