Rent & eviction protection

Is 1801 Turk 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 before 1979
Built 1925

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1925
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 1801 Turk Street property is a 21-unit, 3-story multi-family residential building constructed in 1925, currently owned by 1801 Turk Apartments LLC. The building has undergone several significant improvements in recent years, including a complete kitchen remodel in Unit #14 in 2022 ($18,000), electrical upgrades, and a comprehensive fire alarm system upgrade in 2021 ($20,000) to comply with SF fire code requirements. The property has a documented history of fire safety concerns, with multiple violations and complaints between 2017 and 2023 regarding alarm systems, emergency lighting, and sleeping area requirements, most recently in December 2023. There is an active complaint filed in 2020 regarding the building's soft-story status, suggesting potential structural concerns.

The building has seen various infrastructure improvements, including solar panel installations (2010-2013), a kitchen remodel and plumbing work in 2022, and seismic stiffening work in the garage area completed in 2011 ($57,000). A complaint regarding unauthorized construction work was filed in November 2022, which was subsequently investigated. Between 2023 and 2024, there have been several 311 calls regarding building surroundings, including issues with garbage debris and sidewalk access, though these appear to be external to the building itself. The property has a history of routine safety inspections, with violations typically being addressed promptly, though the recent sleeping area violations remain open. A tenant buyout occurred in 2017 for $10,000.

Risk rating

How 1801 Turk 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.
