Initial analysis

The two-unit residential building at 427-429 Webster Street in Hayes Valley is a two-story structure built in 1900, currently owned by Lara Karchmar. The property has undergone several significant improvements over the past 23 years, most notably foundation work, including a major project in 2013 replacing both exterior (37 feet) and interior (17 feet) foundation walls at a cost of $31,400, and an earlier foundation replacement in 2000 costing $5,000. Other substantial upgrades include window replacements and siding installation in 2013 ($20,000), kitchen remodeling work in 1998, electrical service replacement in 2023, and water heater installation in 2014. The building has been maintained with various infrastructure updates, though some permitted work from 1997 (reroofing) and 2000 (cabinet and appliance installation) is listed as expired.

Recent activity at the property suggests ongoing maintenance and compliance efforts, with the most recent significant work being the electrical service replacement in 2023 and a survey inspection in 2022. The building's maintenance history shows regular upkeep of critical systems, including the foundation, electrical, and plumbing. While there have been numerous 311 calls regarding the vicinity of the building between 2024 and 2025, these primarily concern street parking issues and sidewalk maintenance rather than building-specific concerns. The high volume of parking enforcement calls in recent months (seven citations issued between September 2024 and December 2024) indicates ongoing parking management issues in the area, though these are external matters not directly related to the building's condition or management. The property appears to be well-maintained from a structural and safety perspective, with no recent building-related complaints or violations on record.

Risk rating

How 427-429 Webster 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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

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 75.9%
Moderate concern 12.8%
Severe concern 11.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
