3440 Pierce St

Marina, SF 94123 0463A020 5 units · 2 fl · 1927

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 3440 Pierce 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 1927
2 or more units
5 units
Property type
Multi-Family Residential
Zoning

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1927
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 building at 3440 Pierce Street is a two-story, five-unit multi-family residential structure built in 1927, currently owned by Bypass Tr-delmon Fmly Tr 20. The property has undergone several significant safety and infrastructure improvements over the past decade, most notably a weak story seismic retrofit in 2016 that included the installation of steel moment resisting frames and foundations ($25,000), and a mandatory fire alarm upgrade in 2023 to comply with California state fire marshal code. Recent maintenance includes a gas line repair for the stove in July 2023, and the building's fire safety systems have experienced multiple false alarms, though no actual fires have been recorded.

The building's infrastructure has received consistent attention, with major works including reroofing in 2015 ($11,000), water main replacement in 2013, and various plumbing upgrades. However, it's important to note that the building is currently listed as non-compliant with tier 4 soft story requirements, indicating that while many structural improvements have been made, there are still outstanding seismic retrofit obligations. Recent 311 calls show typical urban maintenance issues, including sidewalk defects (2024), animal waste (2024), and tree-related concerns, though most have been resolved promptly. The property has maintained basic habitability standards with no reported injuries from its recorded fire incidents, which have all involved system malfunctions or false alarms rather than actual fires.

Risk rating

How 3440 Pierce 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
36thpercentile

Out of 988 buildings in this neighborhood, 632 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.

Neighborhood location

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
