405 27Th Ave

Central Richmond, SF 94121 1459001 9 units · 3 fl · 1922

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 405 27Th 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.

Built 1922
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 three-story, 9-unit multi-family residential building at 405 27th Avenue in the Central Richmond neighborhood has been in operation since 1922 and is currently owned by Elvin P & Barbara L Juri Re. The building has undergone several significant safety system upgrades in recent years, most notably a major fire alarm system upgrade in 2023 costing $36,869 to comply with current fire code requirements, with both building and electrical permits issued and completed for this work. The property has a history of fire safety maintenance challenges, with multiple fire-related complaints, including issues with alarm systems and extinguishers reported regularly between 2016 and 2024, though all have been marked as "Condition Corrected" upon follow-up inspections.

The building experienced a cluster of fire safety violations in October 2004, including problems with fire escape ladders, combustible storage, door security, and smoke enclosure doors, all of which were abated by November 2004. Additional safety-related improvements have been documented, including plumbing work completed in 2017 for building sewer and trap systems, and a street space permit issued in 2017. Recent 311 calls related to the property and its immediate vicinity (2022-2024) have primarily concerned external issues such as sidewalk defects, graffiti on public infrastructure, and parking violations, rather than building safety concerns. The most recent building-related maintenance issues involve sidewalk damage and tree root problems, though these are external to the building structure itself.

Risk rating

How 405 27Th 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
4thpercentile

Out of 2250 buildings in this neighborhood, 2160 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Estimated permit spend (past 7 years)

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