Rent & eviction protection

Is 905-907 Diamond 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.

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 905-907 Diamond Street is a two-story multi-family residential building located in Noe Valley, containing three units and constructed in 1910. The building underwent significant renovations in 2009, including a major remodeling project valued at $50,000 that involved interior work on both floors, bathroom and kitchen updates, and new lighting installations to meet energy compliance standards. This renovation also included a re-roofing project ($3,500) that involved replacing shingles and upgrading the roof structure, along with comprehensive plumbing and electrical work. A notable improvement was the installation of an 11-module solar PV system in 2013, demonstrating the building's commitment to renewable energy.

In June 2016, the building underwent a routine safety inspection that identified several issues requiring attention, including the need for handrails, gas utility shutoff tools, and updated safety documentation. These violations were promptly addressed and abated by September 2016. The building has maintained regular upkeep since then, though there have been some recent 311 calls regarding nearby issues such as illegal parking, street pavement defects, and graffiti (April 2024), which are not directly related to the building's condition or management. The property has undergone one significant unit conversion, changing from four to three units in 2009, which included various interior improvements and was processed through proper city planning channels. The most recent building-related permits and inspections indicate that major systems (plumbing, electrical) were upgraded during the 2009 renovation period, and there have been no recorded violations or complaints related to building safety or maintenance since 2016, suggesting the property has been well-maintained in recent years.

Risk rating

How 905-907 Diamond 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
30thpercentile

Out of 1879 buildings in this neighborhood, 1315 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 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.
