Initial analysis

The Seeto Family Trust owns this three-unit, single-story multi-family residential building located at 255 San Carlos St in San Francisco's Inner Mission neighborhood. The building, constructed in 1900, has undergone several significant maintenance activities over its lifetime, with the most recent proper maintenance being a $6,500 reroofing project completed in 2015. This followed a previous reroofing attempt from 1995 which expired without completion. A notable safety incident occurred in 2001 when a tenant suffered a broken toe due to a slanted tread on the front entry stairs, though this complaint was reportedly abated within two weeks.

The most recent incidents of note regarding the property's immediate surroundings include a currently open graffiti case from June 2024 and a curb defect reported in July 2023 that remains open as of October 2023. The area has experienced periodic cleanliness issues, with multiple reports of human/animal waste and loose garbage on the street and sidewalk between 2022-2024, though these have generally been resolved by city services. Several parking-related incidents have been documented, including enforcement actions for sidewalk parking and defaced signs in the vicinity. While the building's structural maintenance seems to have been addressed through roofing work, the surrounding area has experienced ongoing challenges typical of urban settings, including litter, temporary sidewalk parking violations, and periodic graffiti.

Risk rating

How 255 San Carlos 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

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.

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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 65.9%
Moderate concern 21.0%
Severe concern 13.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
