Landscape Permitting in the Bay Area: What Homeowners Should Know
Upgrading your front yard in San Jose, building a backyard retreat in Los Gatos, or adding a patio in Palo Alto? Before you start construction, it’s essential to understand landscape permitting in the Bay Area. Every city and county has its own set of rules, and knowing them ahead of time can help you avoid delays, fines, or costly rework.
Why Landscape Permits Matter
Permits make sure your project complies with:
Local building codes
Zoning regulations unique to your city
Safety standards for structures, utilities, and drainage
They also protect your property’s value and ensure your project doesn’t negatively impact neighbors, water systems, or the environment.
Gas & Electric
Outdoor kitchens that require gas and electric work may require a permit in your area.
When You Might Need a Landscape Permit
In most Bay Area cities, you’ll likely need a permit for:
Retaining walls over 3-4 feet (e.g., San Jose requires a permit for walls over 4 feet)
Decks, patios, pergolas, or gazebos
Outdoor kitchens, gas fire pits, or lighting systems tied to gas or electrical lines
Major grading or excavation (common in hillside areas like Saratoga or Los Altos Hills)
Fence installation over height limits (varies by city; e.g. Cupertino limits most fences to 6 feet)
Driveway expansions or paving changes
Drainage modifications that affect neighboring properties
Retaining Walls
Planning to add a retaining wall in your outdoor space? If it’s over 3-4 ft tall (varies by city), you’ll likely need to secure a permit.
Examples of Local Rules
San Jose: Permit required for retaining walls over 4 feet, any structure with plumbing or electrical, and most grading over 50 cubic yards.
Palo Alto: Strict tree protection: removing heritage or protected species requires approval.
Mountain View: Landscape projects over 500 sq. ft. may require compliance with the California Model Water Efficient Landscape Ordinance (MWELO).
Santa Clara: Requires permits for new irrigation systems tied to the city’s water supply.
Los Gatos: Hillside grading and drainage work often require engineering review.
Special Considerations in the Bay Area
Drought Regulations: California’s MWELO applies to many new or renovated landscapes over 500 sq. ft.
Environmental Zones: Working near creeks, in hillside districts, or coastal zones may trigger environmental review.
Historic Districts: Areas in Palo Alto, Los Gatos, and San Jose may require additional design approval for visible landscape changes.
How to Get a Permit
Visit your city’s planning/building department website—San Jose, Santa Clara, Palo Alto, and other cities publish requirements online.
Prepare a site plan including measurements, utilities, and materials.
Submit the application with any required fees.
Schedule inspections during and after construction.
