Rent & eviction protection

Is 632-634 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 1907
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 1907
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 triplex located at 632-634 Natoma Street in the South of Market neighborhood is a three-story building constructed in 1907, currently owned by Sofia P Rillanos Revoc Lvg and consisting of three flats/duplex units. The building has experienced several significant maintenance issues throughout its history, with the most notable recent concerns emerging in 2020 when multiple complaints were filed regarding structural problems, including reports of the building tilting and rodent infestations in the basement. These structural and maintenance issues seem to indicate a pattern of deteriorating building conditions. The property has undergone various repairs, including stair repairs in 2008 due to dry rot (costing $12,000 initially, revised to $8,000), and has addressed several safety concerns over the years.

More recently, the building has faced ongoing fire safety compliance issues, with violations and complaints related to fire extinguishers and sprinkler systems as recently as 2023 and 2024. A violation was issued in October 2024 regarding sprinkler service and extinguisher service requirements. The building's safety history includes multiple fire safety-related violations in 2008, including the need for fire extinguishers, removal of roof access ladders, and egress obstructions, all of which were subsequently abated. The property has also shown recurring issues with its fire suppression systems, as evidenced by the 2023 fire complaint regarding sprinklers/standpipe systems, which was corrected by November 2023. While the building's permits indicate some maintenance work has been performed over the years, including structural repairs and safety improvements, the recurring nature of safety violations and maintenance complaints suggests ongoing challenges with building upkeep and compliance.

Risk rating

How 632-634 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.
