Initial analysis

The two-story, 12-unit multi-family residential building at 20 Crestline Dr in Twin Peaks, owned by Fairall Jon Roger & Victor, has undergone significant renovations and faced various challenges since its construction in 1964. Most recently, in March 2024, the building completed a substantial exterior improvement project involving stucco replacement on the front and sides at a cost of $60,000. The property has demonstrated compliance with mandatory seismic improvements, completing its Tier 3 soft-story retrofit in 2017, though residents in the upper units reported increased movement during normal activities following the retrofit. Between 2010 and 2021, multiple unit-specific renovations were completed, including substantial work in Units 6, 11, and 12, covering kitchen and bathroom remodels, electrical rewiring, and plumbing updates.

The building has a history of maintenance and safety issues that have generally been addressed over time. Fire safety violations were recorded in 2021 (sprinkler systems) and 2022 (combustible materials storage), though most fire complaints have been found to have no merit. A period of construction-related concerns emerged in 2017 regarding Unit 12, with complaints about extended work duration and potential structural issues, though subsequent permits indicate proper completion of the work. The building underwent a soft-story assessment in 2015, costing $157,000, and completed necessary seismic improvements. Several historical violations from the early 2000s related to fire safety, gas leaks, and building maintenance were recorded but have since been abated. More recent issues include a 2023 sewage backup incident and ongoing concerns with parking violations in the vicinity. The property has maintained an active record of unit improvements and building maintenance, with regular updates to systems including water heaters, electrical panels, and fire safety equipment over the years.

Risk rating

How 20 Crestline Dr'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
