Rent & eviction protection

Is 637-639 Bush 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 1913

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 1913
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-story, 32-unit multi-family residential building at 637-639 Bush Street, owned by 639 Bush LLC, was constructed in 1913 and has experienced several significant maintenance and safety events over its history. Most recently, in 2023, there have been multiple complaints filed regarding water damage and building maintenance issues, including a water pipe burst, problems with kitchen cabinets, window sealing, shower functionality, and floor conditions. The building has a history of fire safety system upgrades, with the most recent improvements in early 2019 including a complete fire alarm system upgrade with new smoke detectors, pull stations, and monitoring modules. Notable infrastructure work includes the replacement of seven Federal Pacific electrical panels in 2014 due to insurance requirements, elevator system upgrades in 2019, and various plumbing improvements in 2015 including water service and stack replacements.

The property has experienced multiple maintenance issues over the years, including significant interior surface damage in 2008 that required repairs to walls, ceilings, and addressing water damage, as well as problems with heating systems and water fixtures noted in various complaints. There have been documented pest issues, including rodent infestations, and recurring maintenance complaints regarding building systems and interior conditions. The building's fire safety record shows several system activations and false alarms, with the most recent violation related to sleeping area requirements issued in December 2023. While many historical violations have been resolved, the building has a pattern of maintenance issues that periodically require attention, particularly regarding building systems and interior maintenance. Recent 311 calls have primarily related to street cleaning and sidewalk conditions rather than building-specific issues.

Risk rating

How 637-639 Bush 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.

Neighborhood percentile
13th percentile

Out of 38 buildings in this neighborhood, 33 are predicted to be safer.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Director's hearing rate, owner's portfolio

Per-building rate of director's hearings across the owner's portfolio.

12-Month severity forecast
No violation 5.6%
Moderate concern 79.3%
Severe concern 15.1%
