2930 Diamond St

Glen Park, SF 94131 6756004 3 units · 2 fl · 1978

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 2930 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 before 1979
Built 1978
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 three-unit, two-story multi-family residential building at 2930 Diamond Street in Glen Park, owned by the Mendoza Family Trust, has undergone several significant maintenance and safety improvements since its construction in 1978. Most recently, in 2018, the building received a reroofing update costing $11,000, following earlier exterior work in 2016 that involved replacing rear siding with moisture barrier protection and installing new smooth resawn siding at a cost of $12,330. The building's maintenance history also includes the installation of a new 75-gallon water heater in 2014, though this permit has since expired.

The property has a history of addressing safety concerns, particularly highlighted by multiple violations identified during a 2001 routine inspection, all of which were resolved by February 2001. These violations included issues with apartment identification, gas meter instructions, egress obstruction, combustible storage in the garage area, and fire safety requirements. The building has undergone several routine inspections over the years (1999, 2001, and 2009), though more recent inspection data is not available in the records. While there have been various 311 calls in the vicinity of the building between 2015 and 2022, most relate to external neighborhood issues such as graffiti, sidewalk cleaning, and encampment concerns, rather than building-specific problems. The most recent documented maintenance work and regulatory compliance efforts demonstrate ongoing attention to building upkeep and safety requirements by the current ownership.

Risk rating

How 2930 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
21stpercentile

Out of 364 buildings in this neighborhood, 288 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
