Initial analysis

The 12-unit, 3-story apartment building at 1671 Lombard Street in Cow Hollow has undergone significant improvements and renovations since its construction in 1925, with particular attention to seismic safety and unit modernization. Most recently, the building completed its mandatory soft-story retrofit in 2019, following a $50,000 project to comply with San Francisco's seismic safety requirements, and was classified as Tier 3 with work completed and Certificate of Final Completion issued. Between 2017 and 2019, there were substantial modifications including the proposed addition of 7 accessory dwelling units (ADUs) in the garage spaces, with associated demolition work and improvements to comply with city ordinances. Various unit renovations have been completed over the years, particularly in 2014, when multiple units underwent kitchen and bathroom remodels, along with electrical updates. The building has experienced some maintenance issues in the past, including a cluster of violations in 2007 regarding lead paint hazards, window repairs, and fire safety concerns, all of which were subsequently addressed and abated by May 2007.

Recent records show ongoing attention to building maintenance and compliance, with a 2022 fire alarm system correction and the successful completion of the soft-story retrofit. The property has had some infrastructure issues, including a sewage backup in March 2024 that was resolved by PUC Sewer Operations. Current external environment concerns have been documented through 311 calls, particularly regarding encampments and street cleaning, though these issues are municipal rather than property-specific. The building's extensive renovation history demonstrates ongoing investment in maintaining and upgrading the property, with all major building permits and improvements being properly completed and documented.

Risk rating

How 1671 Lombard 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 861 buildings in this neighborhood, 689 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 62.5%
Moderate concern 20.6%
Severe concern 16.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
