Rent & eviction protection

Is 522-524 Natoma 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 1909
2 or more units
3 units
Property type

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 1909
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 residential building at 522-524 Natoma Street, located in San Francisco's South of Market neighborhood, is a 1909 construction containing three units. The property has experienced several noteworthy issues in recent years, with the most significant cluster of violations occurring in June 2019, when multiple Notices of Violation were issued for various problems, including a defective heating system in one unit (522A) that was not properly secured to the wall, improper garbage disposal arrangements, and access issues for inspectors. These violations were categorized across different sections including building and fire safety. While these 2019 violations were subsequently addressed and marked as "Not active" by July 2019, their occurrence raises historical concerns about building maintenance.

More recent activity at the property, particularly during June-July 2026, shows multiple 311 service requests primarily related to garbage and debris concerns, with five separate reports of loose garbage, yard waste, and other debris, including an incident involving an abandoned vehicle. While these 2026 incidents have all been marked as resolved, the frequency of garbage-related complaints in this recent period suggests ongoing concerns about waste management at the property. The building's overall record shows a total of 85 311 service requests and 8 Notices of Violation over the past seven years, though most of these violations and complaints are no longer active, indicating that many issues have been addressed through standard regulatory processes.

Risk rating

How 522-524 Natoma 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

Lower risk — safer than most nearby

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

Typical — about average for the neighborhood

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

Higher risk — riskier than most nearby

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

Neighborhood percentile
28thpercentile
