Rent & eviction protection

Is 527 Dolores 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.

Built before 1979
Built 1913

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 three-story, six-unit multi-family residential building at 527 Dolores Street, owned by Ali & Fatemah Khostovan, has undergone several significant structural improvements since its construction in 1913. Most notably, the building completed mandatory soft-story retrofits in 2021 (with prior work in 2018) to enhance seismic safety, and in 2018, an accessory dwelling unit was added at the rear ground floor. The building's electrical system was updated in 2005 with a conversion to underground service with seven meters, and the property previously underwent comprehensive compliance work in 1985.

The building has faced various maintenance and safety challenges over the years, with the most concerning issues occurring in mid-2002 when multiple violations were recorded including problems with fire safety systems, egress, self-closing doors, windows, stairs, and fire protections, all of which were resolved by October 2002. More recent concerns include a 2024 complaint about peeling paint and missing exterior siding, and a 2013 complaint regarding facade bricks and dry rot. The property has also experienced various interior maintenance issues, as documented in complaints from 2011, including problems with plumbing, ventilation, mold, and window functionality. Two fire alarm-related incidents were recorded in 2005 and 2007, with the 2005 issue being corrected. The building's current status shows completed mandatory safety improvements, with recent 311 calls primarily related to park and street maintenance rather than building-specific issues, and no active building violations as of October 2023.

Risk rating

How 527 Dolores 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
6thpercentile

Out of 799 buildings in this neighborhood, 751 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
