Initial analysis

The three-story, 12-unit apartment building at 430 15th Avenue in the Central Richmond neighborhood, owned by Gary and Maggie Chew, has undergone significant improvements and faced various challenges since its construction in 1925. The property completed a mandatory soft-story retrofit in 2018 at a cost of $88,000, achieving Tier 4 compliance. A substantial renovation took place in 2019, converting storage space into a new ADU (Accessory Dwelling Unit) with comprehensive updates including new kitchen and bathroom facilities, followed by the installation of a complete ground floor fire sprinkler system in early 2020 ($10,000). Recent fire safety concerns have emerged, with violations issued in August 2024 for fire extinguisher and alarm system maintenance, though these were subsequently abated.

The building's maintenance history shows regular upgrades to safety systems, including multiple fire alarm system improvements, most recently in 2020 when low-frequency sounders were installed in sleeping areas to meet current code requirements. The property has experienced several fire safety inspections over the years, with most issues being promptly resolved. There was one tenant buyout recorded in 2017 for $24,000 involving two tenants. Recent 311 calls from August 2024 through January 2025 primarily relate to street cleaning issues, including reports of abandoned furniture and debris, which were all resolved. The building's recent history shows active maintenance and upgrading of safety systems, though the 2024 fire safety violations indicate ongoing attention is required in this area.

Risk rating

How 430 15Th 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

Out of 2250 buildings in this neighborhood, 2160 are predicted to be safer.

Model explanation

What's driving this score

Building size

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building permits (past 7 years)

Number of permits pulled at this address — construction or renovation activity over 7 years.

12-Month severity forecast
No violation 22.9%
Moderate concern 63.9%
Severe concern 13.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
