Rent & eviction protection

Is 4073-4075 17Th 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 1907

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 1907
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 4073-4075 17th Street is a 2-unit, 2-story multi-family residential building located in the Corona Heights neighborhood, built in 1907 and currently owned by Paul Jacob Schwarz. The building has undergone several significant renovations over the past decades, with the most recent major work occurring in 2018 involving the conversion of an existing closet into a new bathroom on the second floor, including associated plumbing and electrical work totaling approximately $16,000. In 2016-2017, substantial modifications were made including the reframing of the porch and the conversion of a first-floor area into a second unit with kitchen installation, though this work appears to have triggered some concerns as documented in multiple complaints during 2015 regarding unpermitted construction work, particularly concerning basement level modifications. The building has a documented history of plumbing and electrical improvements, including sewer/housetrap replacement in 2014 and various kitchen-related installations.

More recent concerns have emerged primarily related to property maintenance, with multiple 311 calls between October and December 2024 regarding garbage and debris on the property, though these appear to be primarily street-level issues rather than structural or habitability concerns. A notable complaint was filed in September 2021 regarding alleged unpermitted work on both units, though this case was marked as "Not Active" in March 2022. The building's permit history shows regular maintenance and upgrades, including gas stove installations and various infrastructure improvements, suggesting ongoing investment in property maintenance. The property has also had several street space permits issued between 2014-2018, indicating use of public space for some building-related activities.

Risk rating

How 4073-4075 17Th 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
8thpercentile

Out of 348 buildings in this neighborhood, 320 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
