Rent & eviction protection

Is 3875 18Th 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 1965
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.

15+ years since occupancy
Built 1965
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 12-unit, 4-story multi-family residential building at 3875 18th Street, constructed in 1965, has undergone significant recent renovations including the addition of 5 ADUs (Accessory Dwelling Units) in 2021 and various safety system upgrades. The property has experienced several substantial improvements between 2018 and 2024, with completed projects including a comprehensive fire alarm system upgrade ($40,000) in 2022, bathroom and kitchen renovations in multiple units, and sprinkler system installations. Two recent permits for backyard deck construction were withdrawn in 2024, while a completed permit from 2022 addressed waterproofing near retaining walls.

The building has faced various maintenance and safety issues over the years, with the most serious concerns occurring in 2021 during the ADU construction period, when multiple residents reported problems including door functionality, water leaks, and possible structural concerns. The elevator was out of service for an extended period in mid-2021, and there were several fire safety complaints that have since been resolved, including issues with the sprinkler system (2024) and alarm systems (2023). Historical violations from 2006 related to fire safety equipment maintenance and building structure were documented, though these were subsequently corrected. The property achieved Tier 3 Soft Story compliance, indicating completion of seismic strengthening requirements.

Risk rating

How 3875 18Th 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 1278 buildings in this neighborhood, 1252 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Number of units

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

12-Month severity forecast
No violation 24.4%
Moderate concern 54.8%
Severe concern 20.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
