Rent & eviction protection

Is 670 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.

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 1929
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 8-unit, 3-story apartment building at 670 Lombard Street in North Beach, constructed in 1929, has undergone significant modernization and safety improvements over recent years. Most notably, the building added two new dwelling units in 2017, converting the basement space, which was followed by comprehensive fire safety upgrades including new NFPA 13 fire sprinklers and a modern fire alarm system completed in 2019. The property has successfully completed its mandatory soft-story retrofit program as a Tier 4 building, ensuring improved seismic safety. Recent improvements include a major renovation of Unit #4 in late 2022 to convert it from a one-bedroom to a two-bedroom unit, featuring new bathrooms and kitchen modifications, along with corresponding electrical and plumbing upgrades.

The building has maintained regular housing inspections, with no active violations recorded since 2006. Recent 311 calls primarily relate to exterior street cleaning issues, with the most recent cases occurring in 2024. The property's comprehensive upgrade history demonstrates attention to both resident comfort and safety, with recent improvements totaling over $250,000 in value. The building currently meets all required housing codes and safety standards, with no recorded fire incidents beyond routine alarm system checks and maintenance. The property owner, 670 Lombard St LLC, has overseen systematic improvements to the building's infrastructure, including roofing, plumbing, and electrical systems, ensuring the property remains compliant with current safety requirements.

Risk rating

How 670 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 362 buildings in this neighborhood, 300 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 23.6%
Moderate concern 55.8%
Severe concern 20.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
