Initial analysis

The three-unit, two-story multi-family residential building at 401 Brazil Avenue in the Excelsior neighborhood, owned by Sandra D Perez, was constructed in 1965. The property has undergone several significant modifications and faced various regulatory challenges over its history. Notable improvements include the addition of a family room and bathroom in 2002 ($40,000), and repairs to a wall damaged by a truck in the same year ($20,000). The building experienced multiple safety-related violations between 2001 and 2007, including issues with fire extinguisher maintenance, fire escape ladder functionality, and an incident involving an illegal kitchen setup, all of which were subsequently resolved. A routine inspection in 2011 was documented, and there is a recent approved permit (DPW Referral - 18WR-0406) related to ExteNet Systems (California) LLC.

Recent activity around the property has been primarily related to external maintenance and parking issues. In 2024, there were multiple parking enforcement actions for vehicles blocking driveways and sidewalks. The building faced graffiti issues in late 2023, with two reported incidents in November. Two tree-related maintenance requests were filed in September 2024, regarding tree roots damaging the sidewalk and overgrown trees blocking street lights. The property's location has been subject to recurring parking violations, as evidenced by multiple 311 calls between 2022 and 2024. The building's permitted work history shows a reroofing project from 2001 (permit expired), and while some routine violations were recorded in 2001 regarding fire safety equipment and gas utility requirements, all were abated by March 2001. A significant event in the building's history occurred in 2002 when it was declared an unsafe building, though this issue was resolved within several days.

Risk rating

How 401 Brazil Ave'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
33th percentile

Out of 337 buildings in this neighborhood, 226 are predicted to be safer.

Building size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 48.4%
Moderate concern 22.0%
Severe concern 29.5%
