Bernal Heights, SF 94110 6635021 2 units · 2 fl · 1908

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 10-12 30Th 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.

15+ years since occupancy
Built 1908
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 two-unit residential building at 10-12 30th Street in Bernal Heights, owned by Annamaria Flamburis, has undergone several significant maintenance and improvement projects since its construction in 1908. Most notably, the property experienced water-related issues in 2019 when a toilet supply line rupture in the upper unit resulted in water damage, requiring repairs to both units' bathrooms and kitchens at a cost of $10,000. That same year, the building received comprehensive upgrades including window replacements (21 windows, with 9 street-visible wood sash units), kitchen cabinet installations, and electrical rewiring in the bathroom and kitchen. The building has seen consistent maintenance of its core systems, including a roof replacement in 2017 ($21,300), partial foundation work in 2015 ($8,500) involving replacement of footings and posts, moisture remediation in the yard/patio/basement areas, and HVAC improvements with the installation of gas-efficient furnaces in 2019.

The building's maintenance history shows attention to both structural and comfort improvements, though there have been some concerns worth noting. A significant complaint was filed in March 2016 regarding overgrown weeds and pest issues that reportedly affected neighboring properties, though this complaint is no longer active. The property has experienced plumbing challenges, with a sewer line issue reported in 2001 that took several years to resolve. More recently, there was a sewer-related incident on the property in December 2022, which was resolved by PUC Sewer Operations. The building's systems upgrades include multiple window replacements (2014 and 2019), kitchen renovations, and various electrical improvements. While there have been several 311 calls regarding the property's vicinity (mostly related to street cleaning and parking), these are typical for urban environments and not necessarily indicative of building-specific issues.

Risk rating

How 10-12 30Th 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
33rdpercentile

Out of 1276 buildings in this neighborhood, 855 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
