Rent & eviction protection

Is 835-837 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.

Built 1900

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.

Built 1900
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 835-837 Diamond Street in Noe Valley is a one-story, two-unit multi-family residential building constructed in 1900, currently owned by Gamundi Renaldo M Newman Ju. The building has undergone significant renovations in recent years, most notably in late 2022 when substantial improvements were made to both units including kitchen remodels, bathroom renovations, window replacements, and electrical updates. The 2022-2023 renovation work involved comprehensive upgrades including new plumbing systems with tankless water heaters, electrical rewiring with new lighting and outlets, and structural improvements such as rear siding replacement and skylight installation in Unit 1's kitchen area.

Of particular note is the resolution of a significant historical compliance issue that persisted from 2009 to 2023, involving multiple plumbing violations and unauthorized work that triggered several notices of violation. This was ultimately resolved with final abatement in August 2023, bringing the building into full compliance with plumbing code requirements. The property has also received recent attention for exterior maintenance issues, with records showing tree maintenance requests in 2023-2024 and various parking-related complaints in 2022-2023. Additionally, there was a structural issue requiring external staircase repairs documented in 2014, though this was addressed with proper permits. The building's recent permit history indicates a thorough and comprehensive approach to updating and modernizing the property, with all major renovation work now properly documented and permitted.

Risk rating

How 835-837 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
97thpercentile

Out of 1879 buildings in this neighborhood, 56 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.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.
