Between submitting a permit application and receiving approval to build, every contractor goes through plan review. Most don’t think about it until something stalls. A correction comment comes back, a resubmittal is required, or a building department timeline stretches from days into weeks.
Plan review is where most permit delays originate. Not because the process is arbitrary, but because most submissions arrive incomplete. The wrong product approval number, an unsigned energy compliance form, a trade drawing that doesn’t match the site plan: each gap sends the application back to the queue, adding time and fees to every job it touches.
Contractors who understand what reviewers check, what documentation belongs in the packet before submission, and when private provider plan review cuts weeks off the timeline consistently move permits faster than those who don’t.
What Is Building Plan Review?
Building plan review is the building department’s technical evaluation of submitted construction documents before permit issuance. It is not a formality. Reviewers verify that proposed work meets local building codes, zoning requirements, state energy standards, and trade-specific documentation requirements before construction begins.
A review can be conducted by a municipal building department plan reviewer or by a licensed private provider authorized to perform plan review in place of the local government. Any permit application involving structural, mechanical, electrical, plumbing, or trade-specific work triggers the review process. The result is approved plans, approved with conditions, or denied with correction comments requiring resubmittal.
A denial isn’t a failure. It is a list of items that need to be corrected and resubmitted. The faster a contractor resolves those comments, the faster the permit moves.
What Plan Reviewers Evaluate
Reviewers check the submitted package against a set of technical requirements that vary by trade and project type:
- Site plan compliance with local zoning and setback requirements.
- Structural drawings, load calculations, and connection details.
- Mechanical, electrical, and plumbing system diagrams.
- Energy Code compliance: SHGC ratings, insulation values, and equipment efficiency specifications.
- Product approval documentation: FL# or NOA# designations for Florida impact products, UL listings for electrical equipment, AHRI certificates for HVAC equipment.
- Trade-specific items: solar mounting specs and inverter placement, generator transfer switch wiring, roofing material specifications, pool barrier compliance documentation.
Any item missing from the submitted package triggers a correction comment and delays issuance.
Knowing what reviewers evaluate narrows the gap between a first submission and an approved plan set. The other variable that affects every permit timeline is cost.
Plan Review Fees and What Drives Them
Plan review fees are not standardized. Municipal fees vary by jurisdiction, project scope, and trade type. Most jurisdictions assess them as a percentage of project value or a flat fee per trade. Many apply separate line items for energy review, zoning review, and plan check in addition to the base fee.
Resubmittal fees apply when plans return with correction comments and require a second submission. These add cost and time to the permit cycle, which is why a complete first submission is always the less expensive path.
Florida contractors who use a licensed private provider for plan review and inspections are eligible for mandatory fee reductions under HB 803 (effective July 1, 2026). Commercial permit fees are reduced by 50% when a private provider handles all qualifying plan review and inspections. Partial scope earns a 25% reduction. The mandate applies statewide under Florida Statute 553.792, and no individual municipality can override it.
Contractors in Texas, Georgia, and Tennessee should check with their local jurisdiction for applicable fee schedules, as fee structures vary by municipality and project type.
Fee structure determines what a permit costs. Timeline determines when a job can start. Both are worth understanding before a plan set goes in.
How Long Plan Review Takes and When Expedited Plan Review Makes Sense
Municipal plan review timelines are highly variable. Simple residential permits can clear in a few business days. Complex commercial projects in high-volume building departments routinely take two to six weeks, and that timeline does not account for correction cycles triggered by incomplete submissions.
Delays at this stage stem from four factors: application volume, reviewer staffing, project complexity, and incomplete submittals. Of these, only the last one is within the contractor’s control at the time of submission.
In Florida, HB 803 establishes a 5-business-day review clock for single-family residential permits under $15,000 using a local government reviewer. If the building department misses the deadline, a deemed-approved provision is triggered under Florida Statute 553.791. That protection applies only in Florida and only for the covered project types.
Most jurisdictions offer an expedited plan review track for an additional fee. This accelerates the timeline relative to the standard queue, but it does not eliminate review time or remove the application from the building department’s workload.
Private provider plan review operates entirely outside the municipal queue. Inspected delivers plan review results in 48 hours. Once reviewed, plans move directly into permit application with no gap between review completion and inspection scheduling.
A Plan Review Checklist for Contractors
The fastest path through plan review is a complete, code-compliant submission on the first try. Correction comments require resubmittal, which resets the timeline and adds fees. A clean plan set includes the same core items regardless of trade:
- Scope of work narrative: a written description of all proposed work, trade by trade.
- Contractor license and insurance documentation, current and included in the packet.
- Site plan with dimensions, setbacks, property boundaries, and structure location.
- Trade drawings, fully dimensioned and labeled per jurisdiction requirements.
- Product approval documentation: FL#, NOA#, UL listings, and AHRI certificates as applicable to the trade.
- Energy compliance forms: Manual J, D, and S for HVAC; SHGC and U-factor for windows; PV system specifications for solar.
- Engineer or architect stamp where required, including structural work and most commercial projects.
- HOA approval documentation where applicable.
Permit Hub centralizes document storage and tracks plan review status across all active jobs, so no item gets missed at submission time.
Trade-Specific Plan Review Requirements
Documentation requirements vary by trade. Each system type carries its own submittal standards.
- Mounting system specifications and structural attachment details
- Inverter spec sheet and string layout diagram
- Single-line electrical diagram
- FL# or NOA# for racking components (Florida)
- Equipment spec sheets with AHRI certificate
- Manual J load calculation
- Duct layout diagram
- Transfer switch spec sheet and load schedule
- Standby system placement plan
- Fuel supply documentation
- Material approval documentation
- Deck attachment detail
- Underlayment spec sheet
- FL# or NOA# for each product
- Installation drawings per manufacturer specifications
- Anchor schedule
- Structural drawings
- Electrical bonding plan
- Barrier compliance documentation per the International Swimming Pool and Spa Code (ISPSC)
A complete, trade-accurate submission is the foundation. The next decision is whether that submission runs through the municipal queue or through a private provider.
Private Provider Plan Review vs. Municipal Plan Review
Municipal plan review queues are the single most common reason permit timelines stretch from days into weeks. For contractors managing multiple active jobs, that wait costs real money in crews sitting idle and jobs that can’t start.
Private providers are licensed professional engineers or registered architects authorized under Florida Statute 553.791, and equivalent statutes in Texas, Georgia, and Tennessee, to perform plan review in place of the local building department. Their approvals carry the same legal authority as a municipal approval. Building departments are required to accept them.
Under HB 803, Florida municipalities cannot block contractors from using private providers for eligible projects. The law explicitly prohibits local interference with the private provider process, and the fee reductions for contractors using private providers are mandated at the state level.
The practical difference comes down to time and predictability. Municipal building departments in high-volume markets carry review backlogs that have nothing to do with how straightforward a given project is. Inspected turns plan review around in 48 hours, and reviewed documentation moves directly into inspection scheduling with no gap.
For Texas solar and generator contractors in Dallas, Fort Worth, and Austin, private provider plan review compresses the full permit cycle from application through inspection sign-off, reducing the weeks that municipal queues typically add to installation schedules.
Skip the Municipal Purgatory
When plan review is what’s holding up the permit, private provider review can shave weeks off the timeline. The application process doesn’t change. Reviewed plans move directly into inspection scheduling from the same platform.

Plan Review: Frequently Asked Questions
What Is Plan Review in Construction?
Plan review is the building department’s technical evaluation of submitted construction documents before permit issuance. Reviewers check that proposed work meets local building codes, zoning requirements, energy standards, and trade-specific documentation requirements. The result is either approved plans, approved with conditions, or denied with correction comments that must be addressed before a permit is issued.
How Much Do Plan Review Fees Cost?
Municipal plan review fees vary by jurisdiction and project scope. Most are assessed as a percentage of project value or a flat rate per trade, with separate charges for energy review, zoning, and plan check. In Florida, contractors who use a licensed private provider for all qualifying plan review and inspections receive a mandatory 50% reduction in commercial permit fees under HB 803, effective July 1, 2026.
How Long Does Building Plan Review Take?
Municipal plan review timelines range from a few business days for simple residential permits to two to six weeks for complex commercial projects in high-volume building departments. Incomplete submissions trigger correction cycles that add additional time to the standard queue. Private provider plan review through Inspected delivers results in 48 hours.
What Is Expedited Plan Review?
Expedited plan review is an accelerated review track offered by most municipalities for an additional fee. It reduces the standard timeline relative to the regular queue but does not eliminate review time or remove the application from the building department’s workload. Private provider plan review operates outside the municipal queue entirely and is not subject to building department staffing levels or application backlogs.
Can Plan Review Be Done by a Private Company?
Yes. Licensed private providers are authorized under Florida Statute 553.791 and equivalent statutes in Texas, Georgia, and Tennessee to perform plan review in place of the local building department. Private provider approvals carry the same legal authority as municipal approvals. Under HB 803, Florida municipalities cannot prevent contractors from using a licensed private provider for eligible projects.
