Rent & eviction protection

Is 1270 Grove 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.

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.

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 multi-family residential building at 1270 Grove Street in Alamo Square, built in 1927, has a history of recurring maintenance and safety compliance issues. Most notably, there are multiple active and recently filed violations regarding boiler permit requirements and building safety systems. As of November 2023, the building received two Notices of Violation concerning an unpermitted boiler operation, and in March 2023, several active violations were filed regarding fire safety equipment including fire extinguishers, fire escape maintenance, and compliance affadavits. The building's fire safety systems have undergone periodic attention, with the most recent upgrades including a voluntary fire alarm system replacement in 2017 and a backflow device replacement in 2022, though these systems have also been the subject of multiple violation notices over the years.

The property is classified as non-compliant under Tier 3 soft-story requirements, indicating structural vulnerability in seismic events. Historical maintenance records show various improvements including a roof replacement in 2011 and unit renovations in 2009-2010, but persistent issues with both window functionality (documented complaints from 2013) and building safety compliance have been documented. The building has experienced several fire alarm-related incidents and violations since 2006, with most being attributed to system maintenance issues or equipment requirements. External and common area maintenance concerns are evidenced by multiple 311 calls between 2021-2024, primarily related to street cleaning, graffiti, and a significant flooding incident in 2021.

Risk rating

How 1270 Grove 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

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.

Number of units

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

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.

12-Month severity forecast
No violation 21.5%
Moderate concern 56.9%
Severe concern 21.6%
