How tall can my house be?
A single-family residence is allowed to be up to 30 feet in height in residential zoning districts without requiring a Single Family House Permit. Any proposed new single-family residence that is greater than 30 feet in height (not to exceed 35 feet) will require the submitting of a Single-Family House Permit application and will also require Building Permit.

For specific information on how height is measured, please see our Height Calculation Diagram.
