Initial analysis

The property at 623-625 9th Avenue is a two-unit, two-story multi-family residential building located in the Inner Richmond neighborhood, currently owned by Jennifer J. Bae. Built in 1911 as a flats and duplex structure, the building is undergoing significant recent development with an issued permit in November 2023 for a horizontal addition including an approximately 886 square foot attached ADU, new decks, bay window alterations, and interior remodeling, with an estimated cost of $449,948. The building has undergone several substantial improvements over the past two decades, including window replacements (most recently in 2021 with 9 retrofit fiberglass windows on the 2nd and 3rd stories), a bathroom remodel in 2015, complete reroofing in 2012, and rear stair replacement in 2011. Two plumbing and electrical permits from 2008 document bathroom renovations including fixture relocation and new wiring.

The property has had minimal tenant complaints, with the only recorded building complaint from 2000 regarding inadequate heat, which was promptly addressed. A 2021 fire escape complaint was found to have no merit. While there have been several 311 calls associated with the address between 2013 and 2023, these primarily relate to non-building issues such as parking violations, illegal postings, and street maintenance matters. The most recent building permit activity (2023) indicates ongoing investment in the property's infrastructure and living space, particularly through the new ADU construction. The building's maintenance history shows regular updates to essential systems and features, including multiple window replacements, bathroom renovations, and structural improvements, suggesting generally responsible property management.

Risk rating

How 623-625 9Th 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.

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.

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 85.8%
Moderate concern 10.0%
Severe concern 4.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
