Permit Basics
Building permits vs trade permits
Cities issue two kinds of permits, and most remodels need both. Here is how they differ, who pulls each one, and which common projects need a permit at all. Fees vary by city; look yours up in the permit fee calculator.
Two Types of Permits
Building Permit
Structural & Major Work
Covers structural changes, additions, remodels, and major renovations. Required when you're changing the layout, load-bearing walls, or footprint of your home.
Usually pulled by: General contractor or homeowner
Trade Permit
Specialty Systems
Covers plumbing, electrical, HVAC/mechanical, and roofing. Required when you're touching water lines, wiring, ductwork, or roof structure. Most remodels need trade permits on top of the building permit.
Usually pulled by: Licensed trade contractor (plumber, electrician, HVAC tech)
Work that typically requires a permit:
• New construction (residential or commercial)
• Additions: garage, deck, porch, ADU, carport
• Expanding or demolishing an existing structure
• Swimming pool installation
• HVAC installation or replacement
• Adding, moving, or removing walls
• Roof installation or replacement

Rules vary by city. When in doubt, call your local building department before starting work.
Exemption lists differ by jurisdiction. Each city page shows that city's verified fees and which scopes its building department exempts.
