San Francisco Permits and Local Rules

Trees on private property within 10 feet of the public right-of-way that are 20 feet tall, 15 feet in canopy width or 12 inches in trunk diameter are ‘significant trees’ and need a Public Works permit before removal.

RuleWhat it means for your projectSource
Significant trees (Urban Forestry Ordinance)Significant trees are on private property with any part of the trunk within 10 feet of the public right-of-way and are at least 20 feet tall, 15 feet in canopy width, or 12 inches in trunk diameter at 4.5 feet. They get the same protection as street trees, and a Public Works permit is required before removal.Source
Landmark treesTrees designated by the Board of Supervisors as landmark trees, on public or private land, are protected from physical damage and removal. The page lists designated landmark trees by address, including several in private backyards.Source
Construction Site Runoff Control (SFPUC)Projects disturbing 5,000 square feet up to 1 acre need an Erosion and Sediment Control Plan and a project application to the SFPUC before construction; 1 acre or more needs a SWPPP and application (plus a state Notice of Intent in MS4 areas). Sites under 5,000 square feet must still use best management practices.Source
Call 811 before diggingUnder the Government Code, anyone planning to excavate must contact the appropriate regional notification center (811) at least two working days, and not more than 14 calendar days, before beginning to excavate. USA North 811 adds that each person or company doing the excavation must submit its own ticket; a subcontractor cannot work under another contractor’s ticket, and the day you notify does not count toward the two working days.Source
Construction stormwater permitProjects that disturb one or more acres of soil, or less than one acre if part of a larger common plan of development that disturbs one or more acres, must obtain coverage under the statewide Construction Stormwater General Permit (Order 2022-0057-DWQ, effective September 1, 2023). Projects in the Lake Tahoe Hydrologic Unit apply to the Lahontan Regional Water Board instead.Source
Burning cleared brushA statewide Air Resources Board control measure (effective January 1, 2004) bans outdoor burning of household trash and burn barrels at residences, but dry natural vegetation grown on the property may still be burned in open piles unless prohibited by local controls, and only on days authorized by the local air district. Open burning of land-clearing debris is therefore controlled by the local air district, which may ban it entirely or require permits.Source

How to Choose an Excavation Contractor in San Francisco

Send every bidder the same plans and dimensions. Ask whether the price is per cubic yard, per hour or a fixed total; whether spoil haul-off, imported fill, rock and compaction testing are included; who handles permits and utility locates; and what the finished grade will look like.

For background before you call, read site preparation, excavation cost and land grading. If the site still has trees and brush, start with San Francisco land clearing contractors.

What’s the difference between excavation and land grading?

Excavation digs out or moves earth to reach required depths. Land grading shapes the surface to set slope and drainage. Many sitework contractors do both, but quotes often price them separately.

How are excavation contractors priced?

By the cubic yard, by the machine-hour or as a fixed total. HomeGuide lists $2.50 to $15 per cubic yard for soil and $100 to $300 per hour for an excavator with an operator. Ask which unit a quote uses before comparing bids.
