Rent & eviction protection

Is 518 26Th 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 1922
2 or more units

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 1922
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 518 26th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood, constructed in 1922 and currently owned by Yu Sai Cheong. The building's permit history shows several significant improvements made in 1993, including a completed kitchen and bathroom remodel, a ground floor improvement with half bath addition, and a voluntary seismic upgrade, though the latter two permits have since expired. A construction-related complaint was filed in December 1994 regarding improper construction hours, though this was promptly resolved the same day.

The building has had three fire-related complaints filed between 2007 and 2011, all categorized as "Uncategorized Complaint" or "Unlicensed Auto Repair," but records indicate that conditions were corrected in each instance. More recent history from 2022 through 2024 shows a consistent pattern of street-related issues, primarily involving parking violations and debris, though these are external to the building itself. There have been multiple reports of garbage and debris (both resolved), three abandoned vehicle reports (all resolved), two sidewalk parking violations resulting in citations, and one driveway blocking incident with a citation issued in July 2021. A routine housing inspection complaint was filed in January 2017, though its resolution status is not clearly indicated in the records. The most recent service calls primarily relate to street cleaning and parking enforcement, suggesting ongoing neighborhood issues with parking compliance and sidewalk maintenance in the immediate vicinity of the building.

Risk rating

How 518 26Th 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

Out of 2250 buildings in this neighborhood, 855 are predicted to be safer.
