Rent & eviction protection

Is 1901 Beach 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
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 9-unit, 3-story multi-family residential building at 1901 Beach Street in the Marina neighborhood was constructed in 1928 and has undergone several significant improvements over the years. Most notably, the building completed a mandatory soft-story retrofit in 2015 at a cost of $33,000, achieving compliance with San Francisco's seismic safety requirements. Recent building maintenance has included window replacements, plumbing updates such as a new main drain line installation in 2015, and various electrical improvements. The property has experienced several building violations, with the most recent in 2018 regarding safety and maintenance issues, including fire escape maintenance, carbon monoxide detector installation, and concerns about lead-based paint, though all these violations were officially abated by 2014.

The building has undergone regular maintenance and repairs, including a complete reroofing and garage mudsill repair in the early 1990s. The property has experienced multiple smoke detector activations over the years, all determined to be due to malfunction, with the most recent false alarm pattern continuing into 2024. Fire safety inspections have occurred periodically, with the most recent fire complaint in December 2024 regarding alarm systems showing "No Merit." The surrounding area has seen various street-level issues typical for urban settings, including parking violations and abandoned vehicles, though these are external to the building itself. Recent 311 calls have primarily been related to street cleaning and parking enforcement matters. The building's history shows active management and response to maintenance issues, with significant improvements made to meet current safety standards, though the persistence of false alarm activations remains a notable pattern in the building's recent history.

Risk rating

How 1901 Beach 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
4thpercentile

Out of 988 buildings in this neighborhood, 948 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
