Rent & eviction protection

Is 3270 Harrison 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 1900
2 or more units

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.

Built 1900
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 two-unit, two-story multi-family residential building at 3270 Harrison Street in Bernal Heights, owned by Mary Ann Chavez, has a lengthy history since its construction in 1900. The property experienced significant maintenance and safety issues in early 2016, when multiple building violations were documented, including problems with electrical fixtures, electrical systems, stairs, and lead-related concerns, along with requirements to replace hollow core entry doors and paint walls, trim, and front stairs. These violations were all addressed and abated by March 17, 2016. The building also underwent plumbing work in 2023 with the replacement of two furnaces, though this permit has since expired. An electrical permit from 2016 related to bathroom electrical modifications has also expired.

More recent activity at the property includes multiple parking-related incidents recorded through 311 calls in 2023-2024, primarily involving abandoned vehicles and driveway blocking issues, though these are external to the building's condition and maintenance history. The frequency of parking violations in the immediate vicinity suggests ongoing challenges with street parking in the area. The building's age and permit history indicate some investment in maintenance and upgrades over time, though the expired permits suggest there may be some work that remains incomplete. Notably, there are no documented tenant buyouts at this address, and the last major concern regarding building violations dates back to 2016, suggesting that the property has been relatively stable in recent years, from a violations perspective.

Risk rating

How 3270 Harrison 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
92ndpercentile

Out of 1276 buildings in this neighborhood, 102 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
