Initial analysis

The property at 48-50 Retiro Way is a two-unit, two-story multi-family residential building located in San Francisco's Marina neighborhood, built in 1925 and currently owned by Kathryn Anne Descalso Revoc. The building has undergone significant renovations in recent years, most notably a major $225,000 remodeling project completed in 2022-2023 that included expanding conditioned space on the first floor, reconfiguring kitchens and bathrooms in both units, removing walls between living and dining rooms, and replacing front windows with wood, true divided lite equivalents. The property has seen substantial infrastructure improvements in 2023-2024, including the installation of two new bathrooms, a shower pan, kitchen renovations, laundry facilities, and comprehensive HVAC updates including new furnace systems and heat pumps. Additional plumbing improvements were made in 2020 and 2014 with sewer repairs and drain line replacements.

The building's recent history includes a tenant buyout in September 2022, involving three tenants and totaling $54,500. Earlier construction attempts, including a 1986 third-floor addition and a 1988 bathroom partition project, were either expired or cancelled. The property has experienced minimal external issues, with only a few municipal service requests noted between 2012 and 2023, including a resolved blocked sidewalk incident and a pavement defect that was recently addressed. The comprehensive recent upgrades suggest significant investment in improving both safety systems and resident comfort, though prospective tenants should note the building's age and the substantial scope of recent renovations, which have likely improved the overall living conditions compared to previous decades.

Risk rating

How 48-50 Retiro Way'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 988 buildings in this neighborhood, 10 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.

Neighborhood location

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

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 91.9%
Moderate concern 5.6%
Severe concern 2.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
