Rent & eviction protection

Is 451-453 Lombard 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 1914
2 or more units

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 1914
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 451-453 Lombard Street is a three-story, two-unit multi-family residential building located on Telegraph Hill, owned by Amy Holmen Ovalle and Greg. Built in 1914, this flats/duplex structure has undergone several significant renovations and faced multiple compliance issues over the years. Most notably, in 2017-2018, there were violations regarding egress obstruction and unpermitted construction of a rear stairway/deck that required correction of guardrail standards, which were subsequently addressed with permit 201801178858. The building has undergone substantial improvements since 2016, including a voluntary seismic upgrade ($52,000) and comprehensive interior renovations of the first story ($122,850), along with complete house rewiring and various plumbing upgrades in 2017. The property's maintenance history includes exterior stair reconstruction in 1999 and earlier interior improvements, such as kitchen remodeling in 2004.

Several historical concerns have been documented, including an illegal room construction complaint in 2004 that was investigated in 2007, and issues with the rear stairway balcony modifications in late 2017. The property has maintained active compliance with building safety requirements, as evidenced by prompt responses to violations and completion of necessary improvements, such as raising guardrails to meet code requirements. Recent records show no active violations or complaints, though there was a documented blocked exit issue in July 2018 that was referred to the Department of Building Inspection. The building's plumbing and electrical systems have received significant attention, with major work completed in recent years, including sewer replacement in 2010 and various bathroom and kitchen updates in 2017. Planning records indicate efforts to legalize a 415 sq. ft. nonconforming addition constructed circa 1970, which was completed through the appropriate processes.

Risk rating

How 451-453 Lombard 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
83rdpercentile

Out of 684 buildings in this neighborhood, 116 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
