What Is a Building Permit and Why You Need One

A building permit is official approval from your local building department that allows you to proceed with construction or renovation work. It confirms your project complies with building codes established by the International Code Council, zoning laws, safety regulations, and structural requirements.
What Building Permits Cover
Safety and Structural Integrity:
- Ensuring your project meets current building codes
- Verifying proper structural support and load calculations
- Confirming electrical, plumbing, and HVAC work meets safety standards
- Protecting against fire hazards and ensuring proper egress
Legal Protection:
- Establishing legal documentation of approved improvements
- Protecting your property value and insurance coverage
- Ensuring compliance with zoning restrictions
- Providing liability protection for contractors
Quality Assurance:
- Professional review of construction plans and specifications
- Scheduled inspections throughout the construction process
- Verification that work meets local standards and best practices
Which Home Projects Require Building Permits
Understanding when you need a permit prevents costly surprises and project delays. Requirements vary by location, but here are general guidelines:
Projects That Always Require Permits
Structural Changes:
- Adding or removing load-bearing walls
- Room additions and second-story additions
- Garage conversions to living space
- Basement finishing projects
- Major kitchen and bathroom remodels
Systems and Safety:
- Electrical panel upgrades and new circuits
- Plumbing system changes and new bathrooms
- HVAC system installation or major modifications
- New fireplaces and wood-burning stoves
- Roof replacement and major repairs
Exterior Construction:
- Deck and patio construction (typically over 30 inches high)
- Pool installation and major landscaping changes
- Fence installation (height restrictions vary)
- Shed construction over specific square footage
- Driveway and significant hardscaping changes
Projects That May Not Need Permits
Cosmetic and Minor Improvements:
- Interior painting and wallpaper installation
- Flooring replacement (same level)
- Kitchen cabinet replacement without plumbing changes
- Window and door replacement (same size and location)
- Minor electrical work like outlet installation
Small Exterior Projects:
- Landscaping and gardening without structural changes
- Small repairs under specific dollar amounts
- Routine maintenance and cleaning
- Storage sheds under size thresholds (varies by location)
When in Doubt, Check First
Contact your local building department to confirm requirements. What’s exempt in one city may require permits in another, and it’s always better to ask than face penalties later.
Project-Specific Permit Requirements & Costs
Different projects have varying permit complexity and costs. Here’s what to expect for popular renovation types:
Kitchen Remodels ($300-$1,500 in permits)
Minor kitchen updates like cabinet replacement don’t require permits, but full remodels with plumbing, electrical, or structural changes do. If you’re moving the sink, adding new circuits for appliances, or removing walls, expect to pull multiple permits. The complexity of kitchen renovations makes working with experienced professionals essential.
Calculate your complete kitchen remodel costs including permits, materials, labor, and all associated fees based on your location.
Bathroom Renovations ($200-$1,200 in permits)
Moving plumbing fixtures, changing layouts, or altering electrical systems triggers permit requirements. Even simple fixture upgrades may need permits depending on your location. Bathroom work involves water and electricity in close proximity, making proper permitting and inspection critical for safety.
Get accurate bathroom renovation cost estimates with permit fees factored into your total project budget.
Home Additions ($800-$5,000+ in permits)
Any addition that increases your home’s square footage requires permits for structural, electrical, plumbing, and HVAC work. Room additions are among the most permit-intensive projects because they affect your home’s footprint, structural integrity, and multiple building systems. Expect a thorough plan review and multiple inspections.
Estimate your room addition costs including architectural plans, engineering, permits, and construction with our location-based calculator.
Deck Construction ($100-$500 in permits)
Decks higher than 30 inches typically require permits. Size, height, and attachment to the house affect permit complexity. Ground-level decks may be exempt in some jurisdictions, but elevated decks need structural review and inspections to ensure proper footings, framing, and railings.
Price your deck installation project with material options and local labor rates.
Basement Finishing ($500-$2,000 in permits)
Converting unfinished basement space to living area requires permits for electrical, plumbing (if adding a bathroom), egress windows, and ceiling height compliance. Basement projects often reveal unexpected issues like inadequate headroom or improper drainage that must be addressed during the permit process.
Calculate basement remodel costs including all permit requirements for your specific project scope.

Building Permit FAQs
How much does a building permit cost?
Permit costs range from $100-$500 for small projects like window replacements to $2,000-$10,000+ for major additions or new construction. Most jurisdictions calculate fees based on project value, typically 0.5-4% of total project cost. Use our renovation cost calculators to see permit costs factored into your complete project budget.
How long does it take to get a building permit approved?
Simple permits may be approved in 1-3 weeks, while complex projects requiring plan reviews can take 1-3 months. Factors include project complexity, department workload, and completeness of your application. Submit complete, accurate applications to speed the process.
What happens if I don’t get a required permit?
Unpermitted work can result in stop-work orders, fines of hundreds to thousands of dollars, required demolition, insurance claim denials, and serious complications when selling your home. The risks far outweigh the cost and time of getting proper permits.
Can I pull my own permit as a homeowner?
Yes, homeowners can pull permits for work they’re completing themselves in most jurisdictions. However, you’re responsible for ensuring all work meets code requirements and passes inspections. For complex projects, consider working with licensed contractors who handle permitting.
Do I need a permit to replace kitchen cabinets?
Cabinet replacement alone typically doesn’t require permits. However, if you’re also moving plumbing, adding electrical outlets, or making structural changes, permits are required. Full kitchen remodels with system changes always need permits.
Will unpermitted work affect my home sale?
Yes, unpermitted work frequently causes problems during home sales, including buyer demands for corrections, lender requirements for permit documentation, title issues, and potential price reductions. Always get proper permits to protect your investment.
How do I find out what permits were pulled on my property?
Contact your local building department and request permit history for your address. Most departments maintain public records of all permits issued. This information is essential when buying a home or planning renovations.
What’s the difference between a building permit and a zoning permit?
Building permits confirm your project meets construction and safety codes. Zoning permits verify your project complies with land use regulations, setbacks, and property restrictions. Many projects require both.
Do bathroom renovations require permits?
Most bathroom renovations require permits, especially if you’re moving plumbing fixtures, changing layouts, or altering electrical systems. Simple fixture replacements might not need permits in some jurisdictions. Calculate your bathroom renovation costs including all permit requirements.
Can I start work before my permit is approved?
