Initial analysis

The property at 478 27th Street in Noe Valley is a two-unit multi-family residential building constructed in 1900, currently owned by Wendy Scott Bertrand Living. The building has undergone several significant improvements over its lifetime, with the most recent being a complete roof replacement in October 2023 involving the installation of 30-year composition shingles at a cost of $15,000. Historical records show various maintenance and improvement projects, including the installation of a sewage ejector system (1986), replacement of wooden retaining walls with concrete walls (1984), and the addition of a horizontal wood deck (1987).

The property has undergone important structural changes, including a variance approval that permitted the conversion from a single-family to a two-family dwelling and the creation of an open parking space, though this resulted in a reduction of the rear yard space to 5 feet, below the required 15 feet. More recent external maintenance issues have been primarily related to the surrounding infrastructure, including an open pavement defect reported in April 2024 and various parking-related incidents. There have been multiple service requests regarding street maintenance and parking enforcement between 2016 and 2024, including responses to illegal postings, overgrown trees, and temporary moving sign requests. The building's maintenance history shows regular upkeep, with most permitted work being completed successfully, though some older permits from the 1980s did expire without completion.

Risk rating

How 478 27Th 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
76th percentile

Out of 1879 buildings in this neighborhood, 451 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 age

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

Neighborhood location

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

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 83.2%
Moderate concern 12.6%
Severe concern 4.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
