Is 544 Guerrero 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.
Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.
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.
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.

Unlock complete reportThe three-story, six-unit building at 544 Guerrero Street in Mission Dolores, constructed in 1925 and owned by 544 Guerrero St LLC, has experienced several significant issues in recent years, particularly in 2023. The property has been classified as a nuisance under Section 1001-d of the San Francisco Housing Code due to multiple violations, including improper storage of combustible materials in the unsprinklered garage associated with unit 3, peeling interior surfaces, and access issues during inspections. These violations are documented in four Notices of Violation filed in August and September 2023. A concerning fire safety issue was reported in June 2025 regarding a fireplace in apartment #3 that allegedly leaks smoke into apartment #5 when in use. The building has recently undergone some improvements, including the upgrade of its fire alarm system in February 2023 to comply with Section 1103.7.6.1, which included the installation of low-frequency sounders in living and bedroom areas at a cost of $21,600. Historical records show regular maintenance challenges, with 85 311 service requests filed in the past seven years, including multiple reports of garbage and debris issues, and four Department of Building Inspection (DBI) complaints between 2023-2025, all of which have been marked as not active. The building's maintenance history suggests ongoing efforts to address various interior and exterior maintenance issues, though concerns about resident safety and compliance with building codes persist as evidenced by the recent violations and classification as a nuisance property.

How 544 Guerrero 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.
Out of 799 buildings in this neighborhood, 727 are predicted to be safer.
