Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1221 Potrero Ave rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Just-cause eviction

Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The property at 1221 Potrero Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1908 and owned by German R. and Blanca L. Moncada, this flats and duplex-style building has a documented history of various maintenance and safety-related issues. The most significant historical event was a fire incident in 1995, after which permits from 1991-1994 show work related to fire safety, including the installation of a fire wall between units. The building has undergone several important repairs and upgrades in recent years, including electrical system improvements in 2013 (replacement of plastic junction boxes with metal, main panel upgrade) and structural maintenance in 2018 (repair of non-visible rear stairs and landing).

Recent concerns have primarily centered around maintenance and environmental issues, with an ongoing pattern of graffiti incidents recorded between 2023-2024, affecting the building, sidewalk, and nearby street areas. While most previous structural concerns were addressed promptly, as evidenced by completed permits for roof shingle replacement (2012) and rear stair repairs (2018), an unresolved back door security issue, rotting back stairs, loose floorboards, and inoperable windows were documented in a 1999 housing complaint, though these issues were marked as abated shortly thereafter. The building's electrical system has been modernized, with permits showing significant upgrades to accommodate new systems, and while recent 311 calls primarily relate to external graffiti issues, there have been some utility maintenance matters such as a burnt-out street light that was promptly repaired in 2024.

Risk rating

How 1221 Potrero 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
