The building permit process determines when you can start construction, how many inspections you will face, and when you can hand over a finished building. General contractors who master this process save weeks on project schedules. Those who treat it as an afterthought absorb costly delays. A 2024 survey by the Associated General Contractors found that permit delays added an average of $28,500 in carrying costs per commercial project.

This guide walks through every stage of the building permit process, from pre-application research to final certificate of occupancy.

Step 1: Research Jurisdiction Requirements Before You Apply

Every jurisdiction handles permits differently. Before you submit anything, answer these questions:

Which building department has jurisdiction over your site?
What code editions and local amendments are in effect?
Does the project require a pre-application meeting?
Are there concurrent review processes (fire, health, environmental)?
What is the current plan review timeline?

Call the building department directly. Their website may be outdated. Ask the permit technician for the current review timeline, required submittal documents, and any pending code changes that could affect your project.

Step 2: Assemble Your Permit Application Package

A complete application package prevents the most common delay: incomplete submittal rejection. Most commercial permit applications require:

Document	Purpose	Who Prepares
Permit application form	Identifies project scope, owner, contractor	GC or owner
Construction drawings (architectural)	Shows building layout, materials, finishes	Architect
Structural drawings and calculations	Proves structural adequacy	Structural engineer
MEP drawings	Shows mechanical, electrical, plumbing systems	MEP engineers
Energy compliance forms	Proves energy code compliance	Architect/engineer
Geotechnical report	Confirms soil conditions for foundation design	Geotechnical engineer
Site plan	Shows setbacks, grading, utilities, access	Civil engineer
Owner authorization	Confirms owner approves the application	Owner

Missing even one document sends your application back to the end of the review queue. Create a jurisdiction-specific checklist for every project.

Step 3: Navigate the Plan Review

Plan review is where the building department verifies that your drawings comply with applicable codes. The review covers structural, fire and life safety, accessibility, energy, and zoning provisions.

First review typically takes 2-6 weeks for residential and 4-12 weeks for commercial projects. Understaffed departments in high-growth areas can take longer.

Plan review comments come back as a list of corrections. Each comment references a specific code section. Your design team must respond to every comment with revised drawings or written explanations.

Re-review of corrected plans takes another 1-4 weeks. Projects with extensive corrections may go through three or more review cycles. Each cycle adds weeks.

To minimize review cycles, schedule a pre-submittal meeting with the plan reviewer. Walk through your design approach on complex items before formal submittal. This upfront investment saves weeks on the back end.

Step 4: Pay Fees and Receive Your Permit

Permit fees vary widely by jurisdiction and project value. Most jurisdictions calculate fees based on construction valuation using ICC building valuation data tables.

A $5 million commercial project might generate $25,000-$75,000 in total permit fees across all disciplines. Fees cover plan review, inspections, and administrative costs.

Once fees are paid and plans are approved, the building department issues your permit. Post it on site before any work begins. An unposted permit is the same as no permit in the eyes of an inspector.

Step 5: Schedule and Pass Inspections

Inspections verify that construction matches the approved plans. The building permit process requires inspections at specific milestones. Skipping an inspection or covering work before inspection constitutes a code violation.

Schedule inspections 48-72 hours in advance. Confirm the specific items the inspector will review. Have approved plans, specifications, and any required test reports on site and accessible.

When an inspection fails, get the correction notice in writing. Fix the cited items. Call for re-inspection only after you have verified the corrections are complete. Calling for re-inspection before the work is ready wastes the inspector's time and pushes your next inspection further out.

Step 6: Handle Changes During Construction

Projects change. When they do, the building permit process requires you to file for a revision or a separate permit depending on the scope of the change.

Minor field changes that do not affect structural, fire safety, or energy compliance may be handled through a field revision approved by the building official. Major changes require a formal plan revision submittal that goes through another review cycle.

Document every change. If the inspector finds work that does not match the approved plans and you cannot produce an approved revision, the work is non-compliant.

Step 7: Obtain Your Certificate of Occupancy

The certificate of occupancy (CO) confirms that the building meets all applicable codes and is safe for its intended use. No CO means no occupancy, no tenant move-in, and no revenue.

Final inspection for the CO covers everything: structural, fire protection, MEP systems, accessibility, site work, and life safety. The inspector walks the entire building. Every system must be operational and code-compliant.

Common CO delays include incomplete fire alarm testing, missing elevator inspections, unfinished accessibility features, and outstanding plan review comments. Build a CO punch list 30 days before your target date and track it daily.

How the Permit Process Connects to Broader Construction Regulations

The building permit process is one piece of the construction regulations puzzle. Permits interact with building code compliance, energy standards, and OSHA requirements throughout the project lifecycle.

On Davis-Bacon projects, federal agencies may impose additional permit conditions related to labor compliance, environmental review, and historic preservation. These conditions add time and documentation requirements to the standard permit process.

Digital Permit Platforms

Many jurisdictions now accept electronic permit applications through platforms like Accela, Tyler Technologies, and OpenGov. Digital platforms allow you to track review status, receive comments electronically, and schedule inspections online.

Digital systems speed up the process when they work well. However, technology problems at the building department level can create new delays. Always confirm receipt of electronic submittals with a phone call.

FAQs

How long does the building permit process take from application to permit issuance? Timelines vary dramatically by jurisdiction and project type. Residential permits in efficient jurisdictions can issue in 2-4 weeks. Commercial permits in major metros commonly take 8-16 weeks. Complex projects with multiple review agencies can take 6-12 months. Contact your building department for current timelines before setting your project schedule.

Can you start site work before the building permit is issued? Some jurisdictions issue separate grading or demolition permits that allow site preparation before the building permit issues. You cannot start any building construction without the building permit. Starting work without a permit can result in double fees, stop-work orders, and potential demolition of unpermitted work.

What happens if the building department loses your permit application? This happens more often than you would expect. Always keep copies of your complete submittal, proof of delivery, and payment receipts. If the department cannot locate your application, your copies serve as proof of filing date. Digital submittals with email confirmations reduce this risk.

How many inspections does a typical commercial project require? A mid-size commercial project typically requires 15-25 inspections across all disciplines. Large or complex projects can exceed 50 inspections. Each trade (structural, mechanical, electrical, plumbing, fire protection) has its own inspection sequence. Coordinate inspection scheduling across trades to avoid conflicts.

Can a GC appeal a plan review comment? Yes. If you believe a plan reviewer has misinterpreted the code, you can request a meeting with the senior plan reviewer or building official. Bring your code analysis and supporting documentation. If the dispute remains unresolved, most jurisdictions have a formal Board of Appeals process.

What is a temporary certificate of occupancy and when should you use one? A temporary CO (TCO) allows partial occupancy while minor punch list items remain incomplete. TCOs have expiration dates, typically 90-180 days. If punch list items are not completed before expiration, the TCO lapses and the space becomes non-occupiable. Use TCOs strategically when tenant move-in dates cannot wait for final completion.
