Rent & eviction protection

Is 301 Clipper 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 1926

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.

Built 1926
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 9-unit, 3-story apartment building at 301 Clipper Street in Noe Valley, owned by Clara Martorana Exempt Family, was constructed in 1926 and has undergone several significant safety improvements over the years. Most notably, in 2023, the building received a comprehensive fire alarm system upgrade, including the installation of 5 new pull stations, 5 smoke detectors, and low-frequency sounders in sleeping rooms, followed by additional work in September 2023 adding horns/strobes on the ground floor. The building's safety systems have been consistently maintained, with recent fire safety concerns being addressed promptly, including a violation for emergency lighting repair in 2024 that was abated. The building completed its mandatory soft-story retrofit work (classified as Tier 3) in 2015, which included the installation of new hold downs and shear walls at the ground floor, demonstrating compliance with San Francisco's seismic safety requirements.

The property has a history of addressing maintenance and safety issues, with several building violations from 2001 that were resolved by September of that year, including concerns about fire escape ladders, fire proofing, and staircase repairs. More recent building complaints include damaged basement ceiling surfaces (2023) and previous issues with water leaks and wall cracks (2010), though these have been resolved. The building's infrastructure has been modernized over the years, including the installation of 66 replacement windows in 2003, upgrade of electrical systems with 50A subpanels in 2020, and the addition of a new steam heating boiler in 2010. Recent 311 calls from 2024-2025 primarily relate to parking enforcement issues, which while not directly related to building conditions, indicate ongoing neighborhood activity around the property. The building's maintenance record shows regular attention to both fire safety systems and general building upkeep, with most issues being addressed promptly as they arise.

Risk rating

How 301 Clipper 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 1879 buildings in this neighborhood, 1766 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
