Initial analysis

The 4-unit multi-family residential building at 223 27th Ave in Sea Cliff, owned by Wayman & Christina Wong Family, is a 2-story apartment structure built in 1971. The building has undergone several significant improvements in recent years, most notably a substantial renovation of Apartment #1 in 2022, which included a kitchen remodel with new cabinets, countertop, and appliances, as well as a bathroom update with new vanity and fixtures. This renovation was accompanied by plumbing work to replace the shower pan and valve, and electrical work to upgrade the panel to 240 volts with 70 amps.

The building's maintenance history reveals some past challenges, particularly a cluster of violations in April 2002 related to fire safety and lead paint concerns, including issues with smoke detectors, egress obstructions, and the need for a gas utility shutoff tool. These violations were all addressed and abated by May 23, 2002. An earlier structural improvement was made in 1991 with the installation of plywood basement walls. The most recent activity related to the property was a 311 call from February 2024 regarding an overgrown tree in an alleyway, though this request was cancelled as the alleyway is privately maintained. The building's recent renovations and the prompt resolution of past violations suggest attentive management, though prospective tenants should note the building's age and history of past violations that occurred over 20 years ago.

Risk rating

How 223 27Th 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 20 buildings in this neighborhood, 2 are predicted to be safer.
