Initial analysis

The property at 1249-1251 12th Avenue is a two-unit, two-story multi-family residential building located in the Inner Sunset, built in 1908 and currently owned by Tony C. Shieh. The building has undergone several significant maintenance and improvement projects over the past three decades, including a $13,000 reroofing project in 2018, kitchen remodeling at unit #1251 in 1992, and a substantial $30,000 roof repair in 1992. In 2015, major repairs were completed on the detached rear garage's dry rotted sections, which measured approximately 12'-6" x 20'-6". The property faced a notable period of vacancy in 2016, which led to a complaint regarding failure to comply with the Vacant or Abandoned Building Ordinance, primarily due to signage and exterior maintenance issues; however, this violation was abated within two months.

The building's recent history has included various municipal service calls, with the most recent being related to an encampment issue in September 2024. There have been multiple complaints regarding tree-related concerns, including property damage from tree roots affecting sidewalks (reported in 2020 and 2022). Parking-related issues have been frequent, with several illegal parking complaints recorded between 2019 and 2024, though most were resolved through enforcement action. A single fire-related incident was recorded in November 2008, which was determined to have no merit. While the building has required regular maintenance and responded to various urban challenges typical of its location, there have been no recent serious safety concerns or significant structural issues noted in the available records.

Risk rating

How 1249-1251 12Th 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
52th percentile

Out of 1493 buildings in this neighborhood, 717 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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 78.4%
Moderate concern 14.3%
Severe concern 7.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
