Initial analysis

The property at 77-83 Colton Street is a 2-story, 4-unit multi-family residential building constructed in 1908, currently owned by Wsf Properties LLC. The building has undergone several significant improvements over the past decade, including a complete reroofing project in 2021 costing $13,700, extensive kitchen and bathroom upgrades in 2014 (completed) valued at $114,000, and window replacements in 2015 ($12,000). Major plumbing work was performed in 2014-2015, including the replacement of tubs, fixtures, and water lines in three units, as well as a sewer line and housetrap replacement in 2009. The building has experienced recurring fire safety issues, with violations noted for blocked exits in 2023 and 2017, multiple fire code violations in 2024, and several fire complaints between 2011-2014. While most fire-related incidents have been non-destructive (including false alarms and incorrect calls), the property has demonstrated ongoing challenges with maintaining safety compliance.

Recent activity around the property has primarily involved numerous sanitation-related 311 calls in January 2025 regarding garbage and debris, including reports of human waste. The building's maintenance record shows regular attention to basic infrastructure, with electrical system upgrades, gas line installations, and various cosmetic improvements throughout the years. Historical inspection records from 2003, 2008, and 2011 show routine safety inspections have been conducted, though specific findings from these inspections are not detailed in the available data. The most recent known fire violation from March 2024 was issued regarding an alarm system maintenance issue at 53 Colton Street, which was subsequently abated. The pattern of improvements suggests ongoing investment in maintaining and upgrading the building, though the recurring fire safety violations indicate an area requiring continued attention.

Risk rating

How 77-83 Colton 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.

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 59.4%
Moderate concern 18.8%
Severe concern 21.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
