Rent & eviction protection

Is 474-478 Sanchez 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 1912

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 1912
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 three-unit residential building at 474-478 Sanchez Street, owned by Andrew Tam, is a three-story flats and duplex structure built in 1912 in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant improvements in recent years, with the most substantial ongoing work occurring in Unit A, which includes a kitchen and bathroom remodel, electrical upgrades, and plumbing improvements for new appliances in mid-2024. Recent maintenance includes a complete roof replacement in 2008 and a tankless water heater replacement completed in 2024. A notable water intrusion issue was reported in March 2023, involving leaking fixtures and ceiling damage, though this was subsequently addressed by July 2023.

The building has experienced various violations and complaints over the years, with the most recent cluster of issues identified in March 2023, including problems with weatherproofing, lighting, and interior surfaces, as well as concerns about potential lead-based paint. These violations were marked as not active, suggesting they were resolved or addressed. Earlier violations from 2011 regarding a wooden utility ladder were also resolved. The property has maintained regular updates to essential systems, including plumbing (with a sewer line replacement completed in 2012) and electrical systems (with recent rewiring work completed in 2022). Recent 311 calls primarily relate to exterior maintenance issues, including graffiti and garbage concerns on the property grounds, with one sidewalk defect case still open as of March 2022.

Risk rating

How 474-478 Sanchez 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
