Rent & eviction protection

Is 1604 Treat 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 property at 1604 Treat Avenue is a two-unit, two-story multi-family residential building located in Bernal Heights, constructed in 1908. The most recent significant event involved repairs to the building's front siding in September 2023, following damage caused by a vehicle, though this work was non-structural and cost approximately $5,000. The building underwent a major transformation between 2018-2019 with the conversion of an existing storage area into an ADU (Accessory Dwelling Unit), which included comprehensive plumbing and electrical work, new kitchen and bathroom installations, and radiant heating systems, costing around $95,000. Other notable improvements include a complete reroofing project in 2019 ($10,600), a kitchen and dining room remodel in 2008 ($36,000), and various infrastructure improvements such as a foundation drain installation in 1995 and garage repairs in 2003.

The building's maintenance history shows regular upkeep of essential systems, including a P-trap replacement in 2022 and multiple plumbing and electrical updates, particularly during the ADU conversion period. The property has experienced multiple incidents of abandoned vehicles in the vicinity, with ten reports between October 2024 and December 2024, though none of these incidents directly impacted the property itself. The building appears to be well-maintained, with all permitted work completed to code and no recorded safety violations or resident complaints in recent years. The ownership group, Cheryl M. and Christopher M. Porro, appears committed to maintaining and upgrading the property, as evidenced by their regular investment in improvements and prompt response to maintenance issues.

Risk rating

How 1604 Treat 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
91stpercentile

Out of 1276 buildings in this neighborhood, 115 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 location

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

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.
