Rent & eviction protection

Is 577-579 37Th 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 before 1979
Built 1964
2 or more units

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 1964
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

This two-unit residential building, located at 577-579 37th Avenue in San Francisco's Outer Richmond neighborhood, has undergone significant improvements and changes since its construction in 1964. The most recent major upgrades include the installation of a comprehensive fire safety system, with a new fire sprinkler system implemented throughout the first floor in 2023 (cost: $21,500) and a sprinkler monitoring system added in March 2024 (cost: $14,525). In 2022, the property underwent a substantial transformation with the addition of an ADU unit on the first floor, completed at a cost of $85,000. The building has seen consistent maintenance and improvements over the years, including a complete reroofing in 2020 ($9,000), extensive remodels of multiple bathrooms and kitchens across different floors in 2019 ($128,000), and updates to lighting fixtures on the second and third floors.

The property has maintained active attention to its systems and infrastructure, as evidenced by subsequent plumbing and electrical work to support the ADU integration and other renovations. While the building's recent history shows proactive maintenance and improvements, there have been several parking-related issues in the vicinity, with multiple reports of unauthorized parking on sidewalks and driveway blockages between 2018 and 2024, though these are external to the building itself. The property has no recorded tenant buyouts, and all major recent permits have been properly completed, indicating responsible ownership and ongoing investment in maintaining and upgrading the building's facilities.

Risk rating

How 577-579 37Th 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
99thpercentile

Out of 1040 buildings in this neighborhood, 10 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.

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.
