Mission Dolores, SF 94110 3577012C 8 units · 2 fl · 1928

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 3548 18Th 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.

Annual rent increase cap

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 8-unit, 2-story multi-family residential building at 3548 18th Street in Mission Dolores, owned by the Shapiro Family Trust, has undergone several significant safety and infrastructure upgrades in recent years. Most notably, in April 2023 and October 2023, comprehensive fire alarm system improvements were implemented, including the replacement of the existing panel, addition of low-frequency sounders in sleeping areas, and updates to notification appliances. The building has also received important infrastructure maintenance, such as the replacement of a backflow device in September 2022 and the installation of a new hot water storage tank in 2009.

The property has a history of fire safety and building maintenance issues requiring attention. Active violations from an October 2010 inspection remain outstanding, including concerns about the central alarm system, combustible storage, fire proofing materials, lighting, interior walls, weather proofing, and plumbing. These violations were documented during a routine inspection that also identified potential lead paint concerns. The building's maintenance history includes several permits for street space usage in 2005 and 2015, though more recent records show numerous 311 calls from late 2024 regarding street cleaning issues, graffiti, and other minor infractions, all of which were generally resolved through normal city processes. While the building has undergone significant safety system upgrades, the active violations from 2010 suggest there are still outstanding building maintenance and safety compliance issues that require attention.

Risk rating

How 3548 18Th 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
19thpercentile

Out of 799 buildings in this neighborhood, 647 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.

Building size

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

Number of units

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

Neighborhood (ZIP code)

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