Planning Your Saratoga Addition
- Pre-design: we confirm zoning, survey, easements and net site area. Lots with an average slope over 8% need a surveyor, and slopes over 10% reduce net site area.
- Geotechnical review if the City Engineer requires it.
Trees (Article 15-50): native trees 6 inches or more in diameter and other trees 10 inches or more are protected, along with street and heritage trees. Construction projects need a Tree Preservation Plan, an ISA arborist inspecting at least three times during construction, and a tree security deposit.
Wildfire: Saratoga adopted the 2025 Wildland-Urban Interface Code (Ordinance 414, November 2025). New construction and roof replacements over 10% in a year need Class A roofing. About half the city is in the Saratoga Fire Protection District, staffed by Santa Clara County Fire since 2008.
