Rent & eviction protection

Is 4548-4554 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 1880
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 4548-4550 18th Street is a two-story, multi-family residential building with 3 units, constructed in 1880 in the Eureka Valley/Dolores Heights neighborhood. The building has undergone several significant improvements over the years, including a solar panel installation in 2014 (16 PV modules, 4.2 kW total), a business accessibility upgrade in 2019 (including door hardware and auto opener installation), and two roofing projects completed in 2012 and 1989. Historical maintenance records show attention to structural elements, with wall repairs and threshold replacements documented in 1991, and a vertical extension completed in 1983.

The property has experienced some maintenance challenges, most notably a sewer leak in 1999 and concerns about a damaged retaining wall along the sewer storm flood drain reported in 2018. Recent records from late 2024 show multiple parking enforcement issues in the vicinity, with six illegal parking incidents and two driveway blocking incidents between December 4 and December 17, 2024, all of which were addressed by parking enforcement officers. The building's safety record is generally positive, with only two fire incidents recorded - one related to electrical equipment (details unspecified) and a medical service response - neither resulting in civilian injuries. The property has maintained compliance with various regulatory requirements, as evidenced by the completed Accessible Building Entrance program and corresponding permit documentation.

Risk rating

How 4548-4554 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
55thpercentile

Out of 1278 buildings in this neighborhood, 575 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
