Initial analysis

The 5-unit, 3-story multi-family residential building at 339-343 Waller Street in Hayes Valley, owned by Leong Bowman and built in 1900, has undergone several significant structural and safety improvements over the years. Most notably, the property completed a mandatory soft-story retrofit in 2014 at a cost of $15,000 to comply with San Francisco's seismic safety requirements. The building has experienced recurring issues with its rear wooden staircase and landings, with active violations dating back to October 2010 regarding stability concerns, although permits were issued in 2012 for repairs. Multiple building code violations were documented in 2004, including problems with fire escapes, alarm systems, and interior water damage, though these were abated by 2005.

Recent safety inspections have identified ongoing concerns with the fire alarm system, resulting in a violation issued in November 2024, though a previous 2023 alarm complaint was found to have no merit. The building's maintenance history includes various improvements such as window replacements in 2005, reroofing work in 1998, and emergency repairs following complaints. The property has maintained compliance with basic safety requirements, as evidenced by the issuance of the Certificate of Final Completion (CFC) for its soft-story retrofit. While there have been occasional street cleaning and debris issues in the vicinity (as evidenced by 311 calls between 2019-2024), these are external to the building itself. The most recent fire alarm violation from September 2024 indicates ongoing attention required for safety systems, though its status as "abated" suggests corrective action has been taken.

Risk rating

How 339-343 Waller St'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 1027 buildings in this neighborhood, 565 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 47.6%
Moderate concern 19.5%
Severe concern 32.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.

Approved - Per ZA bulletin no 4 Six units- required means of egress - EXACT REPLACEMENT 4/1996: The replacement of a legally existing structure with a structure within the same envelope and locations as the structure being replaced is exempt if the demolition and reconstruction are included in the same permit or done as part of the same continuing project so that there is no significant time lapse between the demolition and reconstruction. This exemption is justified because the resulting structure would not be more obtrusive than the structure replaced. This exemption is from the Section 311 notification – not from other Code requirements. If the replacement feature is noncomplying, surrounding owners will receive notice of the variance hearing. NOT “EXACT” REPLACEMENT 4/1996: A stairway conforming to Paragraph 136(c)14 is exempt from notification by Section 311(b). The exemption will also apply to a replacement stairway that is required by the Building Code for egress, if it is larger than the stairway it replaces only to the degree required by the Building Code and if the location and coverage are as close as possible to the replaced stairway. The exemption shall not apply if the replacement stairway includes a firewall while the replaced stairway wasn’t enclosed, unless the firewall in its entirety adjoins a blank wall or is no higher than a permitted fence. 10/96: The replacement of a legally existing feature or portion of a building with that of a feature that is the same size or smaller is exempt from the notification requirement provided the replacement structure is within the same footprint and envelope as the feature or portion removed and the removal and replacement are approved at the same time. This exemption is justified because the resulting structure would be less obstrusive than the structure replaced. This exemption is from the Section 311 notification -- not from other Code requirements. If the replacement feature is noncomplying, surrounding owners will receive notice of the variance hearing
