Rent & eviction protection

Is 2 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 12-unit, 3-story multi-family residential building at 2 Diamond Street in Corona Heights, owned by the Dowd Gerald K Family Living Revocable Trust, has undergone several significant safety improvements since its construction in 1924. Most notably, in 2017, the building completed a $70,000 soft-story retrofit to enhance seismic safety, and in 2015, an emergency fire alarm system replacement was carried out to improve fire safety. Recent building violations from May 2024 revealed multiple interior maintenance issues requiring attention, including repairs to damaged cabinets, window latches, and various interior surfaces, as well as concerns about lead paint that were subsequently abated. The building has experienced recurring issues with its fire safety systems, as evidenced by multiple fire complaints and system malfunctions between 2010 and 2023, though most were resolved promptly.

Historical records show the building has undergone various maintenance and upgrade work, including a kitchen and bath remodel in Unit 4 in 2013, roofing work in 2005, and repair of loose stucco in 1995. The building has faced several operational challenges over the years, including a period of no hot water in 2011, sporadic heating issues, and concerns about unauthorized construction work, though these were generally resolved. A recent roof deck condition complaint was noted in planning records, and multiple fire and safety inspections have been conducted, with most issues being corrected promptly. The surrounding area has experienced some routine urban challenges as documented in 311 calls, primarily related to street cleaning and maintenance issues in 2024, though these are external to the building itself.

Risk rating

How 2 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
2ndpercentile

Out of 348 buildings in this neighborhood, 341 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
