Rules change often, so we confirm the current standards for your parcel during the site assessment.
Other Morgan Hill Rules That Affect Your Project
- Hillside, high-fire and flood areas may need extra applications; development must avoid slopes of 20% or more in the Hillside Combining District.
- Exempt work: fences up to 7 ft, retaining walls up to 4 ft (unsurcharged), sheds of 120 sq ft or less, and low decks of 200 sq ft or less generally do not need a building permit. In-ground pools and spas do.
- Trees: native trees 6 in. or more in diameter and any tree 13 in. or more are protected and need a permit to remove.
- Stormwater: 2,500 sq ft or more of new or replaced impervious surface, such as patios and driveways, triggers post-construction stormwater requirements.
- Septic lots need a separate septic system for a detached ADU.
