Check your property’s environmental information

Check in the Property Information Map (PIM). 

Search with your address or block and lot numbers.

Look in the Environmental Information section.

Check for:

• Slope of greater than 20% or 25%
• Geotechnical risk like landslides and liquefaction
• Soil and groundwater contamination (Article 31 and Maher ordinance)
• Other physical conditions like excess air pollution, archeological areas, and flood zones

Email pic@sfgov.org for additional information on any physical conditions listed for your property.

Projects located on a Hunters Point Shipyard parcel may need to perform enhanced environmental mitigations.

Review the Health Code Article 31 webpage and regulations and submit an application to Public Health.

Projects that disturb 50 cubic yards of soil, or include a change to sensitive use, and are located in the Maher Ordinance area, may be required to perform site assessment and mitigation.

The Maher Ordinance area is any area considered by the Department of Public Health to have known or suspected contamination, including sites with historical industrial uses, areas near freeways, and current or historical underground storage tanks.

Review the Maher Ordinance webpage and submit an application to Public Health.

Check if your project includes:

• Construction of a new building or structure with more than 1,000 square feet of new projected roof area
• Horizontal or vertical additions with more than 500 square feet of new projected roof area
• Shoring
• Underpinning
• Grading, including excavation or fill, of over 50 cubic yards of earth materials

We may also review your project and decide it could have a substantial impact on the slope stability.

Comply with slope protection requirements for your building project.

You will need a report from a geotechnical engineer if your project includes: 

• A new building (except one-story storage or utility like a shed or garage)
• Horizontal additions that increase the footprint more than 50% of the existing square footage
• Slope fills, gradings, special foundations, or other drainage or soil work in the Properties Subject to the Slope and Seismic Hazard Zone Protection Act (SSPA) Ordinance Information Sheet S-05.
