Rent & eviction protection

Is 48-50 Golden Gate Ave 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 48-50 Golden Gate Avenue building is a 6-story, 77-unit multi-family residential structure built in 1911 and located in the Tenderloin neighborhood. The property has undergone significant renovations in recent years, with multiple unit upgrades completed between 2019-2021, including comprehensive kitchen and bathroom remodels in units 108, 300, 304, 604, 608, and 612, typically valued between $15,000-$70,000 per unit. A concerning pattern has emerged recently, with multiple active fire safety violations as of 2024, including issues with sprinkler systems, standpipes, alarm systems, and multiple fire code violations between May and September 2024. There are also active complaints regarding boiler permit renewals from July 2024.

Several maintenance and safety issues have been documented at the property, including a significant sewer backup incident in February 2024 that affected the laundry facilities, a leaking ceiling reported in late 2023, and historical elevator capacity concerns documented in 2019. The building has experienced recurring fire alarm system activations, including a recent alarm in December 2023, though most have been classified as malfunctioning or unintentional with no civilian injuries reported. The property has undergone various infrastructure improvements, including fire sprinkler installations over garbage receptacles in 2020, and more recently, a fire alarm upgrade initiated in July 2023. However, multiple permits for unit renovations and upgrades have been either cancelled or expired, suggesting potential oversight in maintaining up-to-date approvals for ongoing maintenance work.

Risk rating

How 48-50 Golden Gate Ave'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
10thpercentile

Out of 172 buildings in this neighborhood, 155 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

NOV rate, owner's portfolio

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