Initial analysis

The 6-unit, 2-story multi-family residential building at 1250-1252 20th Avenue, owned by Lawrence & Mary Jo Nejasmic, has undergone several significant safety and maintenance upgrades since its construction in 1965. Most recently, in early 2023, the building received important fire safety improvements including a fire alarm system upgrade to meet current San Francisco Fire Code requirements, which involved installing low-frequency sounders in sleeping areas and updating all existing devices to ensure compatibility with the new fire alarm control panel. The building has also seen major maintenance work such as reroofing projects in 2017 and 2006, with the 2017 project costing $11,200.

The property has experienced multiple maintenance and safety-related issues over the years, though many have been resolved. Notably, there were two complaints in 2009 and 2011 regarding security and ventilation issues in Unit #4, including the need for proper bathroom ventilation and deadlatch locks on exit doors. A significant 2011 incident involved a broken skylight in a bathroom causing a pest infestation. More recent concerns include two 2021 complaints regarding unpermitted work and remodeling, though these were addressed within a few weeks of being reported. A routine inspection in 2019 revealed recurring hot water issues, and there is an active routine inspection case from 2019 currently on record. The building's fire safety record includes one documented incident of smoke detector activation due to malfunction in 2009, with no injuries reported.

Risk rating

How 1250-1252 20Th 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.
