Rent & eviction protection

Is 47-51 Collingwood 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.

15+ years since occupancy
Built 1904
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 three-unit multi-family residential building at 47-51 Collingwood St, owned by Mullins Living Trust, is a three-story flats and duplex structure built in 1904 in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant renovations in recent years, most notably a comprehensive 2022 renovation of one unit costing $40,000 that included electrical rewiring, bathroom modernization, kitchen cabinet replacement, and installation of a tankless water heater, followed by plans in 2024 to remove a pantry from the kitchen. Other notable improvements include the 2016 replacement of nine rear windows with new vinyl double-hung windows, and plumbing upgrades including a new house trap and pipe section installed in 2014.

The building's maintenance history shows attention to safety concerns, with multiple housing inspections in 2002 and 2013 identifying various fire safety and building code issues, including problems with fire proofing, stair repairs, and fire extinguisher servicing. These violations appear to have been addressed, as they are listed as "Not Active" in the records. Infrastructure improvements include electrical system upgrades, with a new subpanel and complete rewiring of one apartment, and multiple plumbing upgrades including a recent wall heater replacement in April 2024. While there have been several 311 calls regarding the property, most relate to external issues like sidewalk cleaning and debris removal, with only one instance of graffiti in 2022. The building's fire safety systems were activated once due to a malfunctioning alarm system, with no civilian injuries reported.

Risk rating

How 47-51 Collingwood 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
60thpercentile

Out of 1278 buildings in this neighborhood, 511 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.

NOV rate, owner's portfolio

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Director's hearing rate, owner's portfolio

Per-building rate of director's hearings across the owner's portfolio.
