Rent & eviction protection

Is 1235 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 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 2-story, 6-unit multi-family residential building at 1235 17th Avenue in the Inner Sunset neighborhood, owned by 1235 17 Avenue LLC, was constructed in 1963 and has undergone several significant maintenance and safety upgrades over the years. Most notably, in 2021, the building received substantial safety improvements including the installation of a new fire alarm system ($15,900) comprising various detection and alarm components, and a voluntary seismic retrofit ($150,000) involving the installation of moment frames for structural reinforcement. Prior to these upgrades, the building had undergone re-roofing work in 2013 and addressed dry rot issues in 1998-1999, demonstrating ongoing maintenance of the building's essential systems.

The building has a history of fire safety-related inspections and violations, particularly evident in 2000-2001 when multiple citations were issued for fire alarm system repairs, fire extinguisher maintenance, and fire escape obstructions, all of which were subsequently abated. Since then, there have been no active violations or major safety concerns. The property has experienced four documented fire-related incidents since 2008, including a smoke scare, electrical issue, cooking fire, and alarm activation, though none resulted in civilian injuries. Recent maintenance concerns have shifted primarily to the exterior area surrounding the building, with two active 311 calls from September 2024 regarding sidewalk defects and tree overgrowth affecting the public right-of-way. The building's most recent violations and complaints have primarily been related to parking issues, with multiple citations issued for driveway blocking between 2023 and 2024.

Risk rating

How 1235 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.
