Building Permit Process: Plan Review, Approval, Inspections, and Certificate of Occupancy

Covers the full lifecycle of building permits, from application and plan review through inspections and certificate of occupancy issuance, including the roles of building officials, code compliance verification, and common triggers that affect project timelines.

ARE · Project Management

Overview

Every construction project passes through a regulatory gauntlet before a single wall goes up and after the last fixture gets installed. The building permit process is that gauntlet. It starts with submitting construction documents to the authority having jurisdiction (AHJ), moves through plan review and approval, continues with inspections during construction, and ends with a certificate of occupancy (CO) or certificate of completion.

For project managers, this process is a schedule driver. Plan review delays push back construction starts. Failed inspections halt work. A missing CO means the owner cannot occupy the building. You need to understand each step, who is responsible for what, and where the common friction points live.

The building official's role is straightforward in theory: verify that the proposed design and completed construction meet applicable codes. But in practice, jurisdictions vary widely in their processes, timelines, and expectations. Some delegate reviews to third-party firms. Others split responsibilities between departments for structural, electrical, plumbing, fire, and energy compliance. Knowing your jurisdiction's specific procedures, and building relationships with the officials who run them, is one of the most practical skills a project manager can develop.

This topic walks through each stage of the permit process, explains what triggers permit requirements, identifies where projects commonly stall, and clarifies the architect's and project manager's responsibilities at every step.

Essential

The building permit process has a clear sequence. Understanding each stage, who controls it, and where things break down will keep you from getting blindsided on the ARE and in practice. ## When Is a Permit Required? Most construction work requires a building permit. New buildings, additions, major renovations, and changes of occupancy almost always trigger the requirement. Minor repairs that do not affect structural elements, fire safety features, or electrical systems may be exempt. Some jurisdictions set a dollar threshold for alterations to existing buildings; work below that amount on non-structural items may not require a permit. The key distinction: if the work affects life safety, structural integrity, or occupancy classification, you need a permit. ## Step 1: Preparing Construction Documents Construction documents must be prepared by a registered design professional where required by state law.

Professional

Consider a mid-size architecture firm taking on a 45,000 SF mixed-use project in a city where the building department runs plan reviews sequentially by discipline. Structural goes first, then mechanical, then electrical, then plumbing, then fire, then energy. Each reviewer has a two-week turnaround. That is 12 weeks of plan review before the first correction notice even arrives. The project manager on this job makes a critical early move: scheduling a pre-application meeting with the building department during schematic design. At that meeting, the team learns the city recently adopted the latest energy code edition and now requires COMcheck reports with specific duct leakage testing documentation. The firm's previous projects in this jurisdiction used the older code. Without that meeting, the team would have submitted documents under the wrong code edition, triggering a rejection at the energy review stage and adding another two-week cycle. This scenario plays out constantly.

TLDR

A building permit is required for any work affecting life safety, structural integrity, or occupancy classification. Minor non-structural repairs may be exempt.
Construction documents must be prepared by a registered design professional, show sufficient detail for code compliance review, and include energy compliance documentation (insulation values, fenestration specs, mechanical schedules).
Plan review is ministerial: the building official checks documents against code standards, not personal preferences. If the documents comply, the permit must be issued.
Building permits do not carry conditions. Land use approvals (variances, conditional use permits) carry conditions that must be met before the building permit or CO is issued.
Inspections happen at specified construction milestones (foundation, framing, rough-ins, insulation, final). Failed inspections halt work until corrections are made and verified.
The certificate of occupancy confirms the completed building meets code and authorizes its intended use. A design professional's completion letter typically initiates the final inspection.
Permit fees must be proportionate to the jurisdiction's actual administrative costs. Disproportionate fees may be struck down as an illegal tax.
Vested rights protect developers who have incurred substantial costs and completed substantial construction. Revoking a vested permit can create municipal liability.
Pre-application meetings with the building department reduce surprises and prevent submitting documents under the wrong code edition.

Think of the building permit process like getting a driver's license, but for a building. Before you can drive, you have to pass a written test. That is plan review. You submit your construction drawings to the city, and a reviewer checks them against the building code. Did you design the exits wide enough? Is the structure strong enough? Does the insulation meet energy requirements? If everything passes, you get your permit, which is like your learner's permit. You can start building. But just because you passed the written test does not mean you can drive without supervision. During construction, inspectors come to the site at specific points to make sure the building is actually being built the way the drawings show. They check the foundation before it gets covered up. They check the electrical wiring before the walls close in. They check the insulation before the drywall goes up.
