Inner Mission, SF 94110 3589051 3 units · 3 fl · 1913

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.

Rent & eviction protection

Is 3446-3450 19Th 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.

Built before 1979
Built 1913

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.

15+ years since occupancy
Built 1913
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 property at 3446-3450 19th Street is a three-unit, three-story multi-family residential building constructed in 1913, currently owned by Augustine David Peter. The building has undergone significant modernization and safety improvements in recent years, most notably between 2015-2017, when an extensive renovation project was completed including the installation of a new fire sprinkler system throughout the building, a private residence elevator, and substantial kitchen and bathroom remodels in units 3446 and 3448 ($40,000). Additional upgrades during this period included electrical system improvements (new panel, sub-panel, and numerous fixtures), plumbing upgrades including new kitchen and bathroom fixtures, and various structural enhancements including window replacements and mechanical system updates.

The building's recent history shows attention to safety and modernization, with no active building complaints since 2015 and no reported safety violations since that time. However, there is one significant historical complaint from 1999 regarding a broken pipe affecting the upper unit's kitchen sink. Recent maintenance issues documented through 311 calls have primarily concerned exterior matters such as graffiti, sidewalk cleaning, and a missing sewer vent cover, rather than building infrastructure or safety concerns. A tenant buyout was recorded on March 20, 2020, for 4 tenants totaling $24,200, suggesting either voluntary unit changes or building modifications. The property underwent substantial permitted changes including converting storage space to living space, adding exterior features, and performing foundation work, with all major permits showing completed or properly expired status.

Risk rating

How 3446-3450 19Th 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
65thpercentile

Out of 2380 buildings in this neighborhood, 833 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.

Neighborhood (ZIP code)

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
