Rent & eviction protection

Is 345 Fulton 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 before 1979
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 29-unit, 4-story apartment building at 345 Fulton Street in Hayes Valley, constructed in 1926 and currently owned by 345 Fulton I3 LP, has undergone significant recent improvements and faced several historical challenges. Most notably, in 2022, there was a major permitted project to add three accessory dwelling units (ADUs) at the ground floor, bringing the total unit count to 31, along with upgrades to the fire sprinkler system and a comprehensive modernization of the ground floor assembly ($589,020). Between 2018 and 2022, multiple units (20, 26, 30, 33, 40, 42, 44, 45, and 53) received extensive renovations including kitchen and bathroom remodeling, with many units gaining in-unit laundry facilities. A significant cluster of permits in 2021-2022 focused on modernizing individual units, including units 43, 45, and 53, which underwent kitchen and bathroom rehabilitations and washer/dryer installations.

The building has experienced some maintenance and safety issues over the years. A notable rodent infestation occurred in September 2021, affecting multiple units (24, 25, 26), though it appears to have been addressed through pest control measures. Historical complaints from 2003-2011 indicate various maintenance challenges, including heating system issues, plumbing problems, and general maintenance concerns in kitchens and bathrooms, most of which were subsequently resolved. The building underwent significant fire safety improvements, with violations related to fire systems, smoke detectors, and emergency exits being corrected between 2006 and 2010. Recent 311 calls (2024) have mostly concerned external matters like tree maintenance and sidewalk conditions, with no recent internal complaints on record. The property has maintained active compliance with modernization requirements, as evidenced by the recent ADU addition and various infrastructure improvements, including plumbing and electrical upgrades throughout the building.

Risk rating

How 345 Fulton 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.
