Rent & eviction protection

Is 33-45 Stone 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.

15+ years since occupancy
Built 1913
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 property at 33-45 Stone Street is a two-story, four-unit multi-family residential building located in Nob Hill, constructed in 1913 and currently owned by Sung Kai-min E & Sung Conni. The building's maintenance history shows several significant events, including a reroofing project completed in 2004 at a cost of $5,600 and a street space permit issued in 2007. The building underwent a routine housing inspection in 2005 that revealed multiple violations related to fire safety and building codes, including issues with fire extinguishers, egress obstructions, and handrails, all of which were officially abated by December 2005.

More recently, in December 2024, there was a sewage backup issue reported from a side sewer vent that was resolved by PUC Sewer Operations. The building's location has experienced various urban maintenance challenges over the years, as evidenced by multiple 311 calls between 2017 and 2024, including reports of graffiti, illegal parking, and street cleaning needs. A notable incident involving short-term rental violations was recorded at an adjacent address (39 Stone Street) in 2017, related to illegal Airbnb activity that generated complaints about tourist traffic, though this was ultimately resolved in 2018. The property has maintained active compliance with housing inspections since addressing the 2005 violations, with no subsequent building violations on record, though there have been periodic maintenance and cleaning issues typical for the neighborhood.

Risk rating

How 33-45 Stone 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
82ndpercentile

Out of 1125 buildings in this neighborhood, 202 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
