Rent & eviction protection

Is 473-477 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.

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 1908
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 6-unit, 3-story apartment building at 473-477 Sanchez Street in the Eureka Valley/Dolores Heights neighborhood, built in 1908, has undergone significant improvements and maintenance over recent years under the ownership of 477 Sanchez Street LLC. Most notably, the building completed its mandatory soft-story seismic retrofit in 2018 as a Tier 3 project, which included adding a new dwelling unit as per ordinance 162-16. The property has seen substantial interior upgrades, including multiple kitchen remodels in 2021 and 2022 (incorporating new cabinets, appliances, and plumbing work), and deck and stair repairs in late 2022. In 2012, the top floor underwent extensive repairs following a fire incident, including electrical upgrades and structural work.

The building has a history of addressing various maintenance and safety requirements, including compliance with a 2011 unsafe building complaint and completion of necessary electrical and plumbing permits for recent renovations. Historical records from 2000 show multiple violation cases that were all promptly abated by March 29, 2000, including issues related to stairs, floor coverings, windows, and plumbing permits. Recent 311 calls from 2023-2024 primarily relate to street cleaning matters outside the building, with one noise complaint regarding construction work in 2022. The most recent construction-related complaint was resolved in November 2022, and all recent building permits have been completed or properly filed.

Risk rating

How 473-477 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
