Rent & eviction protection

Is 3865-3867 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.

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 3865-3867 18th Street is a three-story, two-unit multi-family residential building constructed in 1911, currently owned by Peter H Sayre and Wuxian Ouya. The building has undergone significant renovations, most notably in 2011 when a major remodeling project valued at $400,000 was completed, which included the addition of a new garage, master bedroom, bathroom, and extensive interior improvements across both units. This project followed the removal of a non-compliant rear deck that had triggered building violations in 2002, though issues with the deck continued to surface in complaints and violations until 2012.

The property has experienced several maintenance and compliance challenges over the years, with active violations from 2007 related to building maintenance, including issues with weatherproofing, common area cleanliness, interior surfaces, and stairs. Multiple plumbing and electrical upgrades have been performed between 2011-2014, including shower pan installations and electrical work, though some permits from this period show as expired or filed. More recent activity includes several 311 calls regarding the property's immediate vicinity, primarily relating to parking issues and street cleaning matters, with recent cases recorded in 2022-2024 showing ongoing concerns with sidewalk use and graffiti.

Risk rating

How 3865-3867 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
77thpercentile

Out of 1278 buildings in this neighborhood, 294 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
