Building Permit Process (Step-by-Step)

This guide explains the typical building permit process from early planning through approval and inspections. Exact requirements vary by city/county/state and project type, but the workflow below helps you avoid common delays and surprises.

Overview

A building permit is formal authorization from the Authority Having Jurisdiction (AHJ) (city/county building department) confirming that submitted plans meet minimum code requirements for the intended scope. The AHJ — not a platform — issues approvals.

Clients supply project information, authorize scope, and respond quickly to requests.
Architects/Engineers prepare compliant documents and respond to plan-check comments.
Contractors execute means/methods, coordinate field inspections, and document changes.

Important: No one can guarantee permit approval timelines. The most reliable way to move fast is accurate drawings, complete submittals, and fast responses to AHJ comments.

Step-by-step permit process

Below is the typical flow. Some projects skip steps or add specialty reviews (fire, health, utilities, HOA, historic, etc.).

Define scope and constraints

Confirm what you’re building/changing, site constraints, and the expected permit type (building, electrical, plumbing, mechanical, grading, etc.).

Collect project inputs

Address, site photos, existing plans (if any), measurements/as-builts, and jurisdiction requirements. Missing inputs are the #1 cause of early delays.

Determine when licensed design is required

Depending on scope and location, plans may require an architect/engineer. Regulated deliverables must be produced under appropriate licensure where required by law.

Prepare permit documents

Typical set includes drawings, notes, calculations (if needed), and supporting forms. Quality control matters — incomplete sets trigger multiple correction cycles.

Submit to the AHJ

Submit digitally or in person, pay initial fees (varies), and receive a tracking number. The AHJ assigns reviewers.

Plan check review & corrections

Reviewers issue comments. The design team responds with revised sheets, clarification letters, and/or updated calculations as required.

Approval, fees, and permit issuance

After comments are cleared, remaining fees are paid and the permit is issued. Approved sheets are stamped by the AHJ and become the jobsite reference.

Construction & inspections

Contractor schedules inspections at required stages. Field deviations may require revisions or formal changes depending on impact.

Final inspection & closeout

After passing final inspections and meeting any conditions, the permit is closed. Some projects also require certificates, letters, or as-built documents.

Tip: If you want fewer plan-check rounds, aim for “complete submittal” quality: consistent sheets, clear notes, and no missing forms.

Checklist: what to prepare

Having these ready makes it easier for professionals to produce a clean submittal and reduces reviewer follow-ups.

Project address + jurisdiction (city/county)
Scope summary (what changes, size, use, timeline)
Photos of existing conditions + site constraints
Existing drawings (if any) or basic measurements
Utility info if relevant (gas, electrical service, water/sewer)
HOA / historic / zoning constraints (if applicable)
Contractor info (if already selected) and preferred inspection schedule

Common delays and how to prevent them

Missing inputs: Provide photos, measurements, and existing plans early.
Unclear scope: Lock the scope before drafting; document changes before proceeding.
Inconsistent sheets: Ensure sheet coordination (notes, details, dimensions).
Late responses: Reply quickly to requests from reviewers and professionals.
Field changes: Avoid improvising; use RFIs and revisions when needed.

Reality check: AHJ review speed varies. The controllable levers are completeness, coordination, and response time.

FAQs

Short answers to common permit questions.

It depends on jurisdiction, project scope, and how complete the submittal is. Fastest outcomes come from complete documents and rapid responses to comments.

Sometimes. Requirements vary by jurisdiction and scope. If your project involves structural changes, complex systems, or regulated occupancies, licensed design may be required.

No. Only the AHJ issues approvals. The best practice is code-compliant design, complete submittals, and timely responses.

Comments are normal. The design team responds with clarifications and revisions until comments are cleared. Multiple cycles are common for incomplete submittals.
