Initial analysis

The 3-story, 7-unit multi-family residential building at 636 Hyde St, owned by Chan Family Lvg Tr, was constructed in 1917 and has experienced several significant maintenance and safety issues over its history. Most recently, in 2023, Unit 101 underwent substantial renovations totaling $50,000, including mold remediation, bathroom and kitchen remodeling, and electrical work, with plumbing work involving bathroom modifications also performed. The building has a documented history of water-related issues, including plumbing violations in 2007 regarding an improperly installed boiler and storage tank, which were subsequently addressed. A serious mold incident was reported in 2011 affecting multiple areas of the building, though this was abated by 2012. The property has also experienced electrical safety concerns, with reports of open wiring and water in electrical fixtures in 1999, and a cancelled fire alarm system installation permit in 2011.

The building underwent several significant improvements in the early 2000s, including re-roofing work in 2000 and water pipe system upgrades in 2019 when galvanized pipes were replaced with copper. More recently, between 2023 and 2024, there have been multiple encampment and garbage-related issues documented in 311 calls around the vicinity of the building, though these are external to the property itself. The fire safety record shows three incidents between 2010 and 2011, including a water/steam leak, a contained cooking fire, and a building fire with no civilian injuries reported. A fire violation was issued in 2011 related to the alarm system maintenance, which was subsequently closed. The most recent structural work indicates ongoing maintenance and upgrading of the building's systems, though the property has experienced periodic interior maintenance challenges that have required intervention over the years.

Risk rating

How 636 Hyde 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
80th percentile

Out of 448 buildings in this neighborhood, 90 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.

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 31.4%
Moderate concern 28.8%
Severe concern 39.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
