Rent & eviction protection

Is 1340 Natoma 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.

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

1340 Natoma Street is a three-unit multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1907, the property underwent significant redevelopment between 2012-2013, starting with the demolition of an existing two-story, single-family dwelling and the construction of a new four-story building containing three residential units over parking. The comprehensive 2012-2013 renovation included modern safety features such as a complete fire sprinkler system, manual and automatic fire alarm systems, and a new 400-amp electrical service with multiple sub-panels. The building's infrastructure was significantly upgraded during this period, with the installation of individual utilities for each unit including furnaces, water heaters, and multiple bathroom and kitchen fixtures.

Recent records from 2024 show multiple reports of sidewalk cleaning issues, specifically related to human waste or urine, occurring regularly between July and October 2024, though these are primarily external to the building itself. There is also one open noise complaint filed in September 2024. The building's safety systems underwent proper installation and inspection in 2013, including fire alarms and sprinklers, with no recent fire-related incidents or civilian injuries reported. The property management has maintained all required building systems, with the last major internal improvements being completed in 2013. The building's construction and safety improvements were properly documented through various permits, including significant investments in both structural and safety systems, totaling over $1 million during the 2012-2013 period.

Risk rating

How 1340 Natoma 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
