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.

Rent & eviction protection

Is 230 11Th 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 1912
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 15-unit apartment building at 230 11th Street in San Francisco's South of Market neighborhood has undergone significant upgrades and faced several challenges since its construction in 1912. The property experienced substantial fire damage in 2012, leading to extensive repairs and improvements including a complete building renovation costing $350,000. This renovation phase included the addition of two new apartments, a roof terrace, and major updates to all units' kitchens, bathrooms, and utilities. Subsequent safety upgrades were implemented, including a new fire sprinkler system with 141 heads ($30,000), a comprehensive fire alarm system, and complete electrical rewiring ($128,800). The building has maintained active compliance with fire safety requirements, evidenced by a recent sound level verification in sleep areas completed in July 2023, though a sleeping area violation was issued in July 2024 which was subsequently abated.

The property has undergone numerous infrastructure improvements including new gas furnace systems, radiant heating, complete plumbing upgrades, and foundation repairs. A notable tenant buyout occurred in December 2017 for $14,500. Recent complaints in 2024 have primarily related to building exterior issues such as graffiti and debris on public property, while internal systems have shown good maintenance records with regular inspections and prompt addressing of violations. Historical context shows the building was subject to routine safety inspections in the early 2000s, and there were previous issues with fire safety equipment and stairway storage, though these were resolved. A unique aspect of the building's history involved multiple complaints regarding illegal commercial activities in 2015-2016, including unauthorized marijuana cultivation and deliveries, though these issues were ultimately abated through proper enforcement actions.

Risk rating

How 230 11Th 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
13thpercentile

Out of 430 buildings in this neighborhood, 374 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
