Rent & eviction protection

Is 131 Hugo 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 1912
2 or more units
12 units
Property type
Multi-Family Residential

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

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 1912
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, 3-story apartment building at 131 Hugo Street in the Inner Sunset, built in 1912, has undergone significant renovations and faced numerous maintenance challenges over the past several years. Most notably, the building completed its mandatory soft-story retrofit in 2019, costing $90,000. In 2020-2021, the property underwent multiple repairs to address code violations and maintenance issues, including window repairs, foundation work, and basement modifications. There have been recurring plumbing issues, with multiple units experiencing sink, shower, and faucet problems between 2020-2021, and significant electrical upgrades including a new 200-amp service installation in 2019.

Recent concerns include ongoing issues with building cleanliness, as evidenced by complaints in early 2023 about residents throwing trash onto the roof, and more serious issues reported in 2020 involving mold, plumbing leaks, and hot water problems. The building has a history of fire safety violations, particularly during 2017 when multiple citations were issued for blocked exits, electrical systems, and combustible materials, though these were subsequently corrected. A 2023 violation regarding an unpermitted condition remains open. The property has undergone multiple utility system upgrades, including a new steam boiler installation in 2008 and various plumbing repairs. Several 311 calls in 2023-2024 relate to exterior maintenance issues, including garbage management and parking violations.

Risk rating

How 131 Hugo 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
