Rent & eviction protection

Is 3550 San Bruno 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.

Built 1927

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 property at 3550 San Bruno Avenue is a one-story, two-unit multi-family residential building located in Visitacion Valley, owned by Cheng Kai Hang & Lisa Y O C. Built in 1927, this flats and duplex structure has undergone minimal documented major maintenance, with only two significant permits on record: a reroofing project in 2007 costing $8,000, and an electrical upgrade to 175 amps in 2004 (though this permit has since expired).

The building has experienced several maintenance and safety concerns in recent months, particularly throughout 2024. There have been multiple reports of garbage and debris issues, with eight documented incidents between June and December 2024, all of which were resolved by Street and Environmental Services. Of particular concern is a rodent and insect infestation reported in February 2024, which was transferred to the Department of Public Health's Environmental Health division for investigation. More recently, in August 2024, a sidewalk defect involving lifted pavement was reported, though this case was closed due to insufficient address information. The property has also experienced some issues with street signage, with two defacement incidents reported in June 2024—one of which remains open while the other was transferred to the Department of Public Works for resolution. While many of these issues have been addressed through existing city services, the frequency of recent sanitation-related complaints and the documented pest infestation suggest ongoing maintenance challenges in the immediate vicinity of the building.

Risk rating

How 3550 San Bruno 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
45thpercentile

Out of 214 buildings in this neighborhood, 118 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
