Initial analysis

The property at 1239-1241 19th Avenue, owned by Sayres Gaelen, is a two-unit residential building constructed in 1908 in San Francisco's Central Sunset neighborhood. The building has undergone significant improvements and maintenance over recent years, with particular attention to unit upgrades in 2021-2022 including multiple bathroom remodels (guest and master baths), replacement of 22 windows and 1 patio door, and a complete reroofing project. In 2023, several important updates were completed, including HVAC system replacements (furnaces and water heater), electrical service upgrade to 400 amps, kitchen circuit improvements, and the legalization of a wet bar. The building also received a fire-rated door installation in unit 1239 to comply with a physical inspection report (CC-8526).

The property's history includes a notable complaint investigation in 2006 regarding an alleged illegal dwelling unit, though this violation was abated by 2008, and the building was subsequently condo converted and properly recognized as a two-unit structure. Recent maintenance records show regular upkeep and modernization, including plumbing upgrades such as a sewer line replacement in 2023, while safety compliance improvements were made in response to inspection reports. The building's infrastructure has been systematically upgraded, with improvements to electrical systems, plumbing, and safety features, indicating ongoing maintenance and investment in the property. The property has experienced some neighborhood issues typical of the area, such as occasional parking enforcement matters and graffiti incidents, but these are external to the building itself.

Risk rating

How 1239-1241 19Th 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
99th percentile

Out of 814 buildings in this neighborhood, 8 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.

Building permits (past 7 years)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Property class: single-family home

Single-family homes (class A) have distinct violation and complaint patterns from multi-family buildings.

12-Month severity forecast
No violation 88.9%
Moderate concern 9.6%
Severe concern 1.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
