Rent & eviction protection

Is 4126-4128 18Th 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.

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 1908
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 three-unit, three-story multi-family residential building at 4126-4128 18th Street was constructed in 1908 and has undergone several significant modifications over the past decades, most recently focusing on accessibility improvements and commercial use compliance. The ground floor commercial space, now occupied by "Bottle Bacchanal" as an alcohol retail store, underwent several transformations between 2021-2022 including accessibility upgrades (2022) and a substantial renovation in 2003 costing $30,000 that improved the entrance and bathroom facilities. A notable safety incident occurred in late 2022 when a customer was injured on an unguarded bottom stair, leading to a violation notice that was subsequently addressed through new handrail installations.

The building has maintained active compliance with safety regulations, as evidenced by the resolution of various building violations and fire complaints. Recent improvements include the installation of an accessible business entrance mechanism (2022) and replacement of back egress stairs (2018) due to wood rot issues, which included new footings to meet current code requirements. The property has experienced recurring issues with garbage and debris on public property in late 2024, as documented by multiple 311 calls, though these do not directly reflect on the building's condition. Past building permits also reveal attention to infrastructure maintenance, including plumbing work such as house trap replacement (2018) and gas line testing (2013), as well as electrical upgrades (2003). The property has maintained its multi-family residential classification while accommodating commercial space, with the ground floor commercial area undergoing various improvements to comply with current use requirements and accessibility standards.

Risk rating

How 4126-4128 18Th 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.
