Rent & eviction protection

Is 3857-3859 25Th 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
3 units
Property type

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.

15+ years since occupancy
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 3857-3859 25th Street property in Noe Valley is a two-story multi-family residential building constructed in 1900, containing three units and currently owned by Richard Ong. Recent maintenance and improvements include a significant renovation in 2021 that upgraded the kitchen and bathroom facilities, electrical systems (including a 200-amp upgrade), and plumbing infrastructure at a cost of $73,000. The building has undergone several important updates over the years, including re-roofing work in 2017 and 2001, the installation of a skylight in 2012, and various plumbing improvements such as water heater replacements in 2019 and furnace replacement in 2012. A sewer house trap installation was completed in December 2024, which was promptly addressed following a violation notice for a broken house trap that was abated by January 2025.

The property has experienced recurring issues with driveway blocking, particularly by Tesla vehicles, with multiple citations issued between 2023 and 2024. There was also a brief sewer line issue reported in 2004 involving both this property and the neighboring building (3863-25th Street), which was resolved within a month. The electrical infrastructure received attention in 2004 with a 200-amp underground conversion and grounding upgrade, ensuring compliance with modern standards. Separate permits and inspections for plumbing and electrical work in 2021 demonstrate ongoing efforts to maintain and improve building systems, though some older permits from 2000 and 2001 (for sidewalk and roofing work) show as expired rather than completed following historical records review.

Risk rating

How 3857-3859 25Th 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
62ndpercentile

Out of 1879 buildings in this neighborhood, 714 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 permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

Building age

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