Initial analysis

The property at 747-749 18th Avenue is a two-unit, two-story multi-family residential building located in the Central Richmond neighborhood, owned by James & Mary L.S. Tse Revocable Trust and constructed in 1923. This historically significant building has undergone several major renovations, with the most notable being the 2016-2017 legalization of a third unit (Unit No. 3) on the ground floor, which included comprehensive work to add two bedrooms, one bathroom, living and dining rooms, and a kitchen/laundry facilities, along with a complete fire sprinkler system installation costing $105,000. The building's fire safety systems have received particular attention, with recent upgrades including a new sprinkler monitoring system installed in 2022 ($4,000) and the legalization of sprinkler systems for first-floor units in 2020 ($19,075).

The property has seen substantial interior improvements over the years, including extensive remodeling work in 2006-2007 involving kitchen and bathroom renovations, electrical upgrades (200-amp service installation with 3 meter sockets), and the replacement of drywall and insulation in Unit 747. Earlier maintenance records show basic upkeep such as reroofing (1998) and yard stairway repairs (1994). The building's recent history has been relatively quiet in terms of major incidents, though there has been one open case regarding illegal postings from November 2024. Prior 311 calls from 2019 and 2018 primarily related to street cleaning and damaged property issues, while a 2014 report concerned an abandoned scooter that was resolved the following day. The property's extensive permit history and recent upgrading of safety systems suggest proactive management of the building's infrastructure and compliance with current regulations.

Risk rating

How 747-749 18Th 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
75th percentile

Out of 2250 buildings in this neighborhood, 562 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

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.

12-Month severity forecast
No violation 85.9%
Moderate concern 10.7%
Severe concern 3.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
