2806-2810 Diamond St

Glen Park, SF 94131 6744026 3 units · 2 fl · 1890

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 2806-2810 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 1890

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.

Built 1890
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 2806-2810 Diamond Street in Glen Park is a 2-story, multi-family residential building constructed in 1890, containing 3 units plus a commercial space, currently owned by the Randhahn Family Trust. The building has undergone several significant maintenance and improvement projects in recent years, with the most pressing issues occurring in 2024. This includes repairs to rear stairs and deck damage (June 2024), extensive renovations including sewer pipe replacement, electrical panel replacement due to water damage, and tile updates (July 2024), totaling over $49,000 in work. Earlier improvements include a bathroom remodeling project (2022), new LED lighting installation (2021), and various electrical upgrades (2006-2024). The commercial portion of the building has seen recent activity with the installation of a new illuminated "Bank of America" sign in late 2023.

The property has experienced some infrastructure challenges as evidenced by multiple sewer and plumbing repairs, including underground pipe replacement in 2024. A series of 311 calls in 2023-2024 primarily relate to parking meter issues, curb defects, and street maintenance concerns, though these are more relevant to the property's urban context rather than specific building conditions. The building has a history of permitted improvements and maintenance work, including changes of use and sign installations, demonstrating compliance with local regulations. Recent construction projects suggest proactive maintenance of both residential and commercial components, though the frequency of repairs, particularly to exterior elements like stairs and decks, is notable.

Risk rating

How 2806-2810 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
18thpercentile
