Rent & eviction protection

Is 4072 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.

15+ years since occupancy
Built 1901
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-story multi-family residential building at 4072 18th Street, owned by 4072 18th Street SF LLC, was constructed in 1901 and contains two residential units with ground floor commercial space. The property has undergone significant commercial space renovations in recent years, with the most recent permit issued in June 2024 for a $28,000 commercial remodel. There was a notable period of housing violations and complaints in early 2023, with the most serious issues involving heating problems, water damage, and safety concerns including non-compliant smoke/carbon monoxide detectors and fire extinguishers. These violations were abated by February 10, 2023. The building has also experienced maintenance and safety issues involving the residential units, including reports of broken appliances and heating systems, most notably a dangerous unconnected furnace system discovered in July 2022. Recent infrastructure improvements include the installation of new smoke/carbon monoxide detectors in February 2023 and an electrical service upgrade to 400 amps in July 2018.

The property has active planning records indicating ongoing development and compliance work, particularly regarding the ground floor commercial space's change of use from retail to restaurant. There are two long-standing building complaints from 2019 and 2012 that remain active, involving unauthorized exterior work including new siding, trim installation, and window modifications, as well as concerns about construction work beyond permitted scope and an unpermitted rear structure installation. Recent maintenance issues have included two sewer backup incidents in early 2024 and various noise complaints related to the commercial space's operations. The building's commercial space has seen regular changes, with multiple permits issued between 2015 and 2024 for kitchen equipment installations, fire suppression system upgrades, and restroom modifications.

Risk rating

How 4072 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.
