Initial analysis

The three-story, two-unit multi-family residential building at 627 Waller Street in Hayes Valley, owned by Paul W. Pitts, was constructed in 1900 and holds Mills Act Historical Property status. The property has undergone numerous substantial improvements over the years, with the most recent being the installation of a 6.96 kW solar panel system in 2023 (completed in April 2023 with an additional related permit in May 2023). Other significant recent improvements include a completed reroofing project in January 2023 ($19,000) and the installation of permeable pavers in front of the garage in 2021 ($19,500). The building underwent major interior renovations in 2012, including the addition of a master bathroom suite, wet bar, and comprehensive electrical updates ($90,000). Earlier improvements include the construction of a roof deck with safety features in 2013 and various electrical system upgrades between 2004-2017, including PV system installation and garage electrical enhancements.

The building has a history of addressing maintenance and safety issues, with past complaints in the 1990s regarding electrical problems and stair repairs, though these issues were resolved. The property is currently undergoing review for proposed balustrade work to replace non-original railings with historically appropriate alternatives, demonstrating ongoing commitment to historical preservation. Recent 311 calls primarily relate to parking enforcement matters, with multiple reports of vehicles blocking driveways or parking on sidewalks between 2023-2024, though most officers were unable to locate the vehicles in question. There was also a water leak investigation in November 2024, which was accepted by San Francisco Water Department for follow-up.

Risk rating

How 627 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

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 age

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
No violation 89.8%
Moderate concern 8.1%
Severe concern 2.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
