Central Richmond, SF 94121 1453009 4 units · 2 fl · 1923

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.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 347 21St 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.

Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
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 two-story, four-unit multi-family residential building at 347 21st Avenue in the Central Richmond neighborhood, owned by Seiki Fmly Survivor's Tr, was constructed in 1923 and has undergone several significant events throughout its history. The most notable incident occurred in May 2003 when the building faced multiple fire safety violations, including issues with fire extinguisher maintenance, combustible storage, and smoke enclosure doors - all of which were successfully abated by July 14, 2003. The building received a reroofing upgrade in 2004 at a cost of $7,100, demonstrating maintenance attention to basic infrastructure. Three routine housing inspections have been documented, with the most recent occurring in 2009.

In recent years, there has been a series of street-related issues surrounding the property, primarily involving parking violations, with six recorded cases of vehicles blocking driveways or parking on sidewalks between April and June 2023. The sidewalk and street area around the building has also experienced recurring general cleaning needs, with eight reported cases of loose garbage or waste between 2022 and 2023. These exterior maintenance issues, while indicating some challenges in the immediate surroundings, are primarily street-level concerns rather than direct building-related problems. The last documented building-related issue, apart from routine inspections, dates back to 2004 with the completion of the reroofing project, suggesting that major building systems may not have required significant attention in recent years.

Risk rating

How 347 21St 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
18thpercentile

Out of 2250 buildings in this neighborhood, 1845 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
