Initial analysis

The two-unit residential building at 1251-1253 46th Avenue in San Francisco's Outer Sunset neighborhood is a two-story flats and duplex structure built in 1907, currently owned by Sebastian Properties LLC. The property has undergone several significant structural improvements over the years, with the most substantial work occurring in 2005 when major renovations included foundation replacement, lower slab work, steel beam installation, and new deck construction at both units, along with stairwell relocation and first-floor overhang infill. More recent improvements include electrical system upgrades with two 200-amp service installations in April 2023, and earlier work in 2018 attempted to remodel a first-floor 2-bedroom unit's kitchen and finishes, though this permit was withdrawn. The building's maintenance history shows attention to essential systems, including a sewer/housetrap upgrade in 2016, reroofing work in 2009, and various electrical improvements between 2005-2006.

The property has experienced typical urban residential issues as documented in 311 calls, with the most recent incidents involving garbage and debris and illegal parking in late 2023. Several street maintenance issues have been reported and resolved over the years, including pavement defects in 2018 and 2020, as well as a manhole cover issue in 2015 that was addressed through official notice. The building appears to have maintained its structural integrity through proper maintenance and upgrades, with no recorded safety violations or significant resident complaints beyond general urban maintenance issues.

Risk rating

How 1251-1253 46Th 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
59th percentile

Out of 632 buildings in this neighborhood, 259 are predicted to be safer.

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.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

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 64.0%
Moderate concern 28.9%
Severe concern 7.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
