Rent & eviction protection

Is 649 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 1906

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 1906
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

649 Natoma Street is a three-story, multi-family residential building constructed in 1906, housing three units in the South of Market neighborhood. The building's maintenance history shows regular upkeep, including a significant $28,000 reroofing project completed in 2021 and previous roofing work in 1988. Notable structural issues were addressed in 2008 when repairs were made to address wood rot in the deck stairs, which had previously resulted in multiple violations in 2007 concerning both building safety and fire safety (specifically regarding fire extinguisher maintenance). These violations were all resolved by November 2008. A 2019 fire complaint about operating without a permit was found to have no merit by June 2020.

The building's permit history also includes window repairs in 2000 and compliance work in 1986. More recent concerns not directly related to the building's condition include various street cleaning and maintenance issues in 2023-2024, such as garbage and debris clearance, though these appear to be more about general neighborhood maintenance rather than building-specific problems. The property has undergone routine inspections over the years, with the most recent documented case being a 2007 follow-up which showed multiple safety concerns at that time. While there have been some maintenance issues noted over the years, the current status suggests the building is generally well-maintained, with more recent complaints primarily relating to street and sidewalk conditions rather than building-specific problems.

Risk rating

How 649 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
82ndpercentile

Out of 430 buildings in this neighborhood, 77 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
