Initial analysis

The 1642 Hyde Street property in Nob Hill is a 4-story, 6-unit multi-family residential building constructed in 1909, currently owned by Lawrence & Mary Jo Nejasmic. The building has undergone significant safety and modernization upgrades over the past two decades, with the most recent being a fire alarm system upgrade in March 2023 (cost: $28,342) to meet current safety codes. The building completed its mandatory soft-story retrofit (Tier 3) in 2015 (cost: $47,300), significantly improving seismic safety. Major improvements were made in 2007-2008, including comprehensive interior remodels of units 2, 4, and 6, installation of double-pane windows, and substantial electrical upgrades including a new 400-amp service and complete rewire of all units. The building has received regular maintenance attention, with completed fire alarm system installations and upgrades in 2006 and 2023.

The property has experienced three notable complaints or violations since 2003, all of which were promptly addressed. These included a 2005 complaint about construction-related issues such as low water pressure and window drafts (abated within one day), a 2006 complaint regarding unsafe work conditions with asbestos and scaffolding (abated within two weeks), and a routine inspection in 2008 that identified several safety and security compliance items including alarm system certification and exterior door locking devices (all abated by October 2008). The building's maintenance record shows regular attention to safety systems, with the fire alarm system being a recurring focus of upgrades and maintenance. Recent 311 calls from 2024 primarily relate to external issues like street cleaning and parking enforcement, with one call regarding a fallen tree that was resolved by city services. The building is currently in compliance with all major safety requirements, including having completed its soft-story retrofit program.

Risk rating

How 1642 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

Out of 1125 buildings in this neighborhood, 394 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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 47.5%
Moderate concern 23.1%
Severe concern 29.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
