Corona Heights, SF 94114 2656047 4 units · 2 fl · 1900

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 189-191 Corbett Ave 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 two-story, four-unit multi-family residential building at 189-191 Corbett Avenue in Corona Heights, built in 1900, has undergone significant electrical improvements in 2023, with complete rewiring and new subpanels installed in all units between May 1-8, 2023, along with the installation of 150-amp underground service in 2004. The property has a history of various maintenance and compliance issues, with a notable cluster of violations in 2006-2011 related to fire safety and building codes, including problems with handrails, fire escape maintenance, egress obstructions, fire extinguisher requirements, and security features, though all these violations were ultimately abated by June 2012. A 2011 complaint regarding unpermitted deck removal was also resolved.

Recent building maintenance history shows attention to critical systems, particularly with the 2023 electrical upgrades. The property has experienced several infrastructure issues in the surrounding area, including a water main break in 2019, a fallen tree in 2018, and sidewalk defects in 2013. The building underwent mandatory routine apartment inspections in 1998, 2006, and 2011, with all issues being resolved. Two significant tenant buyouts have occurred in recent years, with $100,000 paid to two tenants in 2022 and $137,500 to three tenants in 2024 at a nearby address (193 Corbett Avenue). The building's current owner, Sofia Mitina 2006 Revoc Tr, has maintained the property through periodic repairs and updates, with particular attention to electrical systems in recent years.

Risk rating

How 189-191 Corbett Ave'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
22ndpercentile

Out of 348 buildings in this neighborhood, 271 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
