Initial analysis

The property at 137-139 12th Avenue, owned by the Moreno Trust, is a two-unit, two-story multi-family residential building constructed in 1913 in the Lake - The Presidio neighborhood. The most significant recent development is the 2022 permit for legalizing an unauthorized dwelling unit (UDU) under Ordinance 43-14, which involved relocating an unpermitted kitchen that had been converted from a laundry space, along with installing comprehensive NFPA 13 fire protection on the entire ground floor, with a project cost of $95,500. This followed several substantial improvements between 2003 and 2007, including complete reroofing work ($9,785) in 2003, the addition of a bedroom, laundry room, and full bathroom on the ground floor ($26,000) in 2005, electrical upgrades including new service installation ($2,000) and comprehensive electrical work for ground floor additions, plus kitchen and bathroom remodeling on the second floor ($30,000) in 2006.

The building's recent history includes routine maintenance and some community-related incidents, such as multiple 311 calls for street cleaning (2016, 2017, and 2020) and parking enforcement issues (2020). Earlier records show some minor urban maintenance concerns like graffiti (2015) and an abandoned vehicle report (2015), all of which were resolved promptly. The property's documented improvements suggest ongoing investment in maintaining and upgrading the building, with particular attention paid to bringing previously unpermitted spaces into compliance with current regulations. The UDU legalization project appears to be the most substantial recent modification, significantly increasing the building's living space while incorporating modern safety features.

Risk rating

How 137-139 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
95th percentile

Out of 660 buildings in this neighborhood, 33 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 83.3%
Moderate concern 14.0%
Severe concern 2.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
