Initial analysis

The three-story multi-family residential building at 688-698 Corbett Avenue, located in San Francisco's Twin Peaks neighborhood, was constructed in 1890 and contains 6 units. The property is currently owned by the Family Trust Of Pietila 200 and has undergone several significant maintenance and infrastructure improvements over the years. Most notably, in 2008, major upgrades were completed including water line and sewer line replacements, along with street and sidewalk improvements. Earlier improvements include a complete reroofing of the building in 2007 ($25,450) and remediation of rotted stair components in 2003 ($2,000). An electrical upgrade was attempted in 2004 with an underground conversion to 150-amp service, though this permit status is listed as expired.

The building has experienced two routine housing inspections, one in 2003 and another in 2007, which revealed multiple safety and security concerns that were subsequently addressed and abated. These violations included issues with the fire escape, rear stairs, security requirements (such as door viewers and self-closing devices), and handrail deficiencies. Recent maintenance history shows ongoing attention to basic upkeep, with 311 calls over the past several years primarily related to external issues such as street cleaning, water service requests, and sign repairs. A notable incident in 2020 involved dirt encroachment onto the sidewalk, which was promptly addressed by plumbing contractors.

Risk rating

How 688-698 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

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.

12-Month severity forecast
No violation 66.4%
Moderate concern 22.4%
Severe concern 11.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
