Rent & eviction protection

Is 3435 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 1923
2 or more units

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
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 12-unit, three-story multi-family residential building at 3435 18th Street in the Inner Mission, owned by Litke Marghenta, was constructed in 1923 and has undergone several significant safety improvements over recent years. Most notably, the building completed its mandatory soft-story retrofit in 2017 (with subsequent revisions) at a cost of $82,000, demonstrating compliance with San Francisco's seismic safety requirements. The property has also recently updated its fire safety systems, with a fire alarm system upgrade completed in 2024 costing nearly $35,000, including the installation of low-frequency sounders in sleeping areas and a new fire alarm panel.

The building has experienced periodic safety and maintenance challenges, including a cluster of violations in September 2023 related to fire escape maintenance, gas shutoff requirements, and various compliance affidavits, though these were all abated by June 2024. There was also a significant complaint in June 2017 regarding construction debris during the seismic retrofit work, and a serious incident in 2008 involving scalding water affecting a tenant. The property has maintained an active history of regular updates, including boiler system improvements in 2023 and 2017, electrical service upgrades, and roofing work in 2004 and 1997. Recent inspections and work suggest ongoing attention to building safety, though the frequency of various complaints and violations over the years indicates typical urban building maintenance challenges. The building is categorized as a Tier 3 soft-story property, with its retrofit work completed and certified.

Risk rating

How 3435 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
7thpercentile

Out of 2380 buildings in this neighborhood, 2213 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.

NOV rate, owner's portfolio

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