Rent & eviction protection

Is 1677-1679 48Th 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.

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 1904
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 property at 1677-1679 48th Avenue in the Outer Sunset is a three-story, multi-family residential building comprising two units, constructed in 1904 and currently owned by 1677 48th Ave LLC. The building has undergone several significant renovations and faced multiple challenges over its history, with the most recent major modifications occurring between 2017-2022, including a conversion of a bookroom into a kitchenette, deck repairs, and the addition of bedrooms and a bathroom. The property experienced notable maintenance issues in December 2020, when multiple violations were filed regarding general dilapidation, lead containment, and various safety concerns, including repairs needed for skylights, stairs, and deck boards. These violations were eventually abated by March 2021, following repairs that included electrical work, new fixtures, and smoke detectors installation.

Historical records show substantial improvements made in 2001, including a horizontal addition and significant upgrades to plumbing and electrical systems. Several complaints regarding maintenance issues prior to 2020 were documented, including water intrusion, peeling paint, and mold problems in 1997-2006. The building's recent history (2020-2023) has also seen multiple parking-related incidents in the vicinity, though these are external to the building's condition itself. While the property has experienced various maintenance challenges over the years, the most significant recent issues appear to have been addressed through compliance with housing codes and subsequent repairs, as evidenced by the completion status of related permits and the resolution of building violations.

Risk rating

How 1677-1679 48Th 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.
