Initial analysis

The property at 1263-1265 20th Avenue is a 2-story mixed-use building constructed in 1911, containing 3 residential units and commercial space, owned by Paul Ming Kuan and Hsiu-Ting Do. The building underwent significant renovations in 2006-2007, including a major interior remodel that added bathrooms and laundry facilities, relocated plumbing and kitchen features, and improved exterior siding. This renovation was accompanied by comprehensive electrical upgrades, including the installation of new service panels and wiring. A notable incident occurred in 2007 when unauthorized plumbing work in the commercial space resulted in a violation that was resolved within four months. The property has experienced various maintenance issues over the years, including multiple instances of roof work in 1993 and 2000, and a fire incident in 1989 requiring first-story repairs.

Recent history shows some community concern about unauthorized uses, such as a 2013 complaint regarding an alleged illegal conversion from apartment to hotel with unauthorized kitchen installation, though this complaint was marked as not active. The building and surrounding area have experienced several maintenance-related issues over the past decade, with multiple reports of garbage and debris on the street between 2015 and 2024, though all these issues were eventually resolved. There have also been periodic issues with graffiti, including a notable incident in 2020. The most recent building-related complaints have been primarily focused on exterior maintenance and street cleanliness rather than structural or safety concerns within the building itself.

Risk rating

How 1263-1265 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.

Neighborhood percentile

Model explanation

What's driving this score

Building age

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Property class: apartment building

Severe concern 14.2%
