Rent & eviction protection

Is 3444-3446 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.

Built before 1979
Built 1909

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 1909
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 four-unit multi-family residential building at 3444-3446 18th Street, owned by Bay Community Housing LP, is a two-story flats and duplex structure built in 1909 in the Inner Mission neighborhood. The property has undergone several significant safety upgrades in recent years, most notably a fire alarm system upgrade in May 2024 to comply with current fire code requirements, representing a $29,600 investment in safety infrastructure. The building has a history of maintenance issues dating back to at least the 1980s, with documented repairs for dry rot in walls and stairs, though more recent complaints indicate ongoing concerns. In 2019, there was an active complaint regarding unpermitted roofing work and improperly installed rain gutters, with water drainage issues affecting neighboring properties remaining unresolved as of this report's construction.

Between 2015-2017, the building experienced multiple housing code violations requiring corrective action, including issues with fire safety equipment, egress obstructions, and structural maintenance. Although these specific violations were abated in October 2017, the property has continued to accumulate maintenance concerns, as evidenced by complaints about plumbing issues (washer drainage), pest infestations, and interior deterioration. The building's fire safety history shows regular alarm system activations and false alarms, though notably, there have been no reported civilian injuries from these incidents. Recent 311 calls from 2024 primarily relate to exterior maintenance issues such as graffiti and sidewalk conditions, with multiple cases of graffiti on public infrastructure near the property being reported. The building's management has demonstrated some responsiveness to regulatory requirements, evidenced by recent fire alarm upgrades, though historical patterns suggest ongoing challenges with maintenance and compliance.

Risk rating

How 3444-3446 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
83rdpercentile

Out of 2380 buildings in this neighborhood, 405 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

Neighborhood (ZIP code)

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

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Neighborhood location

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