Rent & eviction protection

Is 1526 Filbert 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 before 1979
Built 1923
2 or more units

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 1923
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 three-story, 15-unit multi-family residential building at 1526 Filbert Street, constructed in 1923 and currently owned by 1526 Filbert LLC, has undergone several significant safety and infrastructure improvements over the past decades. Most recently, in August 2023 and October 2023, the building received a fire alarm system upgrade, including the installation of low-frequency horns in sleeping areas, at a cost of approximately $53,100. The property completed its mandatory soft-story seismic retrofit in 2016, with improvements valued at $125,000, achieving compliance with San Francisco's Tier 3 requirements. The building has a history of multiple fire safety issues, particularly during the 2001-2006 period, when it faced several violations related to fire proofing, fire escape maintenance, smoke enclosure doors, and combustible storage, all of which were subsequently abated by October 2006.

More recent concerns include a 2020 complaint regarding construction noise and work times on an adjacent empty lot, and multiple 311 calls in 2023-2024 regarding general building maintenance and exterior issues. The property experienced regular fire safety inspections and violations between 2006 and 2024, including a 2020 fire code violation related to blocked exits that was corrected by November 2020. The most recent fire-related inspections in early 2024 noted conditions related to hazardous materials and electrical systems that were promptly corrected. The building's maintenance record shows attention to major systems, including a reroofing project from 1996, though some older permits have expired. Recent 311 calls from 2022-2024 primarily relate to exterior maintenance and urban cleanliness issues surrounding the building's location.

Risk rating

How 1526 Filbert 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.
