Augrented Insights
Initial analysis

20 Romolo Street, a 4-story, 15-unit residential building in Telegraph Hill, was constructed in 1907 and is currently owned by 20 Romolo I7 LP. The property has experienced several significant maintenance and safety issues in recent years, with particular concern for its current violations as of October 2025. These violations include issues with the fire alarm system, required gas shutoff tools, missing safety certifications for smoke and carbon monoxide detectors, and concerns about exterior structural maintenance of decks, balconies, and fire escapes. A notable incident occurred in October 2025 involving multiple complaints from Unit 7 on the 3rd floor regarding bed bugs, smoke infiltration, and security failures, as well as reporting persistent soot problems from a 2024 smoke incident in Unit 3 that allegedly affected air quality. The building also experienced a repetitive problem with its fire alarm system, which triggered complaints about alarms going off every two hours in March 2026.

Rent & eviction protection

Is 20 Romolo St 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 1907
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.

Risk rating

How 20 Romolo St'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
2ndpercentile

Out of 684 buildings in this neighborhood, 670 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.
