Initial analysis

The property at 502-508 29th Avenue in the Central Richmond neighborhood is a two-story, 4-unit multi-family residential building constructed in 1922, currently owned by Daniel C. Woo and Yuan Wang. The building has undergone significant renovations in recent years, with a major remodeling project in early 2020 costing $68,000 that included bedroom, kitchen, and bathroom updates plus an additional bedroom in unit 508. This renovation was followed by multiple associated improvements throughout 2020, including the addition of a half bath, structural revisions, and upgrades to electrical systems including a service upgrade from 100 to 200 amps, newly installed radiant heat, and plumbing work involving a new water heater and various fixtures.

The building has had several maintenance and compliance issues over its history, particularly concerning the boiler system. There were violations related to egress obstructions and combustible storage in 2004, which were abated by December 2004. More recent boiler-related compliance matters occurred in 2010 and 2020, though these were also resolved. The property has experienced occasional minor issues as documented through 311 calls, primarily related to external matters such as graffiti, illegal postings, and parking enforcement, with no serious incidents recorded. The building's most recent documented permits and improvements suggest active management and maintenance, with no current violations or active complaints on record.

Risk rating

How 502-508 29Th 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

Out of 2250 buildings in this neighborhood, 1418 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

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 74.5%
Moderate concern 18.3%
Severe concern 7.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
