Rent & eviction protection

Is 1239 17Th 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 1963

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 1963
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, 2-story multi-family residential building at 1239 17th Avenue in the Inner Sunset, built in 1963, has undergone several significant upgrades and faced various maintenance issues over its history. Most notably, in 2021, the building completed a voluntary seismic retrofit costing $150,000, installed a new fire alarm system ($17,307), and underwent substantial improvements to Unit 1 including kitchen renovations ($30,000) with associated plumbing and electrical work. The building has experienced recurring fire alarm system issues, with multiple false alarms and system malfunctions recorded, though no civilian injuries have ever occurred. Past maintenance challenges included multiple instances of dry rot repairs in 1998-1999, three roofing projects (1995 and 2013), and various building code violations primarily in 2006-2009 related to heating, window functionality, and security requirements, all of which were resolved.

Recent activity at the property has focused on infrastructure maintenance and compliance, with a routine fire alarm system inspection in July 2023 showing corrected conditions. External to the building, there have been multiple recent complaints (2024) regarding sidewalk parking issues and tree maintenance, though these are municipal rather than building-specific concerns. The building's management has demonstrated responsiveness to safety and code compliance issues, as evidenced by the comprehensive 2021 upgrades and prompt response to violations when they occur. The property has maintained a generally stable history since the major upgrades in 2021, with no current active violations or complaints related to the building's core systems or structure.

Risk rating

How 1239 17Th 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

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
