Rent & eviction protection

Is 3508-3510 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.

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.

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 two-story, six-unit building at 3508-3510 26th Street in the Inner Mission, owned by Domenic J. Cannizzaro, dates back to 1900 and has experienced several significant events in recent years that warrant attention. Most critically, in January 2025, the building sustained structural damage when a vehicle crashed into its corner, leading to the removal of a structural post and the installation of temporary shoring by the San Francisco Fire Department - this violation is currently active and under monthly monitoring. The building has also faced multiple code compliance issues, including unpermitted electrical work in 2021 involving exterior lighting (now resolved) and unauthorized stair replacement in 2019 (resolved via a building permit obtained in 2020). A fire incident was recorded in the past seven years, though no specific details are provided in the available data.

The property has generated substantial activity on 311 service requests, with 296 recorded over the past seven years, and continues to be the subject of various complaints and service calls. Most recently, there has been a cluster of parking-related complaints in July 2026, with multiple reports of illegal parking and sidewalk obstruction, though enforcement officers were often unable to locate the vehicles involved, except for one instance resulting in a citation. The building's permit record shows limited permitted work, with only two permits issued in the past seven years: one for addressing the 2025 structural damage and another from 2020 for stair replacement, which was completed. The building's violation history, while showing some pattern of unpermitted work, demonstrates that most issues have been addressed through proper channels, though the most recent vehicle-related structural damage remains a significant concern.

Risk rating

How 3508-3510 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.
