Initial analysis

The two-unit residential building at 826-828 Haight Street in Hayes Valley, owned by Alvin and Margaret Montgomery, has undergone several significant improvements since 2012. The most recent major work was completed in 2018-2019, involving attic improvements for storage and access to the furnace, including the installation of new gas lines and a furnace, along with laundry facilities on the second floor. Between 2012 and 2015, substantial structural work was undertaken including a foundation replacement ($45,000), front stairway replacement ($14,000), and garage girder replacement with wall improvements ($10,000). Safety enhancements were also made in 2018 with the installation of hardwired smoke detectors.

The property has a history of violations and complaints from 2005, when there were concerns about unpermitted work including demolition of walls, removal of lathe and plaster, and decking modifications. These issues, along with electrical concerns about improper wiring connections, were eventually resolved by 2012. Subsequent electrical work in 2012 addressed multiple code violations, and various permits have been completed successfully since then. The building's maintenance history shows regular upkeep and improvements, with recent parking enforcement issues in 2024 being the only notable concern, though these are unrelated to building conditions or safety.

Risk rating

How 826-828 Haight 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, 277 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.

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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

12-Month severity forecast
No violation 82.0%
Moderate concern 11.0%
Severe concern 7.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
