Rent & eviction protection

Is 3441-3443 26Th St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1900

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1900
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The 3441-3443 26th Street property is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, constructed in 1900 and currently owned by the 26th Street Residence Trust. The building underwent significant transformation in 2016-2019, including the conversion of a non-conforming ground floor commercial space into residential use, complete with rear horizontal expansion, bathroom additions, and kitchen renovations costing $181,000. This period also saw comprehensive infrastructure updates, including radiant heating system installation, new bathroom and laundry facilities on both floors, and modernization of utilities including a tankless water heater.

The property has a history of building violations from 2008 related to an unpermitted hot tub installation on the roof and expired permits, though these were ultimately abated in 2012. There was a serious building complaint in 1998 regarding roof leaks, cracked walls, and ceiling issues, which was resolved by 2000. Recent years have shown ongoing maintenance activity, including window replacements in 2013, electrical system upgrades, and various plumbing improvements. The building received facade modifications in 2016 to restore base and side paneling, and historical records indicate past issues with unpermitted storefront facade removal and a lot-line window installation, though these were addressed through proper channels. The most recent building systems improvements include a completed electrical service relocation and various plumbing updates in 2019. The property has experienced recurring street-level sanitation issues as evidenced by multiple 311 calls in recent months (2024-2025) regarding garbage and debris, though these are more reflective of the street environment than building conditions.

Risk rating

How 3441-3443 26Th St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
