## Key facts

| Fact | Value |
| --- | --- |
| Small TI / over-the-counter | Same day–2 weeks (if eligible) |
| Mid-size commercial | 3–8 weeks (first review cycle) |
| Large / complex | 8–16+ weeks (multi-agency, multi-cycle) |
| Each resubmittal | +2–6 weeks (back in the queue) |

## Direct answer

Typical plan-review timelines, the factors that drive them, and the expedited, self-certification, and over-the-counter options that can shorten the queue. A key reference is small ti / over-the-counter: Same day–2 weeks; check the cited source, edition, units, and applicability before using it for design, compliance, procurement, or approval. Small TI / over-the-counter is Same day–2 weeks; if eligible. Mid-size commercial is 3–8 weeks; first review cycle. Large / complex is 8–16+ weeks; multi-agency, multi-cycle. Plan-review turnaround scales with project size, the number of agencies involved, and the department's current backlog. Treat the figures below as **illustrative ranges** — the AHJ's own service standards and workload govern any specific project. Read the values with the cited source, edition or observation period, units and applicability; replace illustrative inputs with current project evidence before design, procurement or approval use.

## Which authority and approval steps control the project?

Plan-review turnaround scales with project size, the number of agencies involved, and the department's current backlog. Treat the figures below as **illustrative ranges** — the AHJ's own service standards and workload govern any specific project.

| Project type | First-cycle target | Notes |
| --- | --- | --- |
| Small TI / over-the-counter | Same day–2 weeks | If eligible for OTC or express review |
| Mid-size commercial | 3–8 weeks | Single building department, standard queue |
| Large / ground-up / multi-agency | 8–16+ weeks | Fire, health, public works, zoning in parallel |
| Each resubmittal cycle | +2–6 weeks | Set returns to the queue |

## What drives the timeline

- **Number of review cycles** — the dominant factor; a set that clears in one cycle beats one that loops four times.
- **Completeness at intake** — missing disciplines or forms trigger rejection before the clock even starts.
- **Number of agencies** — parallel reviews by fire, health, zoning, and public works add coordination and dependencies.
- **Department backlog** — seasonal and market-driven queues stretch even simple reviews.
- **Project complexity** — high-rise, assembly, healthcare, and hazardous occupancies invite deeper scrutiny.

## Ways to shorten the queue

- **Over-the-counter (OTC) / express** — same-visit review for small, low-risk scopes that meet the department's eligibility rules.
- **Expedited / priority review** — many AHJs offer a faster track for an additional fee or via third-party plan-review firms.
- **Self-certification / professional certification** — eligible project types let a qualified design professional certify code compliance, reducing department review; scope and eligibility are strictly defined.
- **Pre-submittal meetings** — a pre-application conference surfaces agency concerns before the formal clock starts.

## The fastest lever is your own set

Expediting fees help, but the cheapest way to compress the schedule is to file a **complete, coordinated set** that anticipates the correction comments and clears in one or two cycles. Work the [submittal checklist](https://harth.build/resources/permits/building-permit-submittal-checklist.md), coordinate the disciplines in Harth before you file, and see the full [permit process](https://harth.build/resources/permits/building-permit-process-explained.md) for where review fits in the sequence.

## How Long Does Building Plan Review Take? (2026): jurisdiction verification record

| Approval field | Project entry | Official evidence |
| --- | --- | --- |
| Site address and parcel | — | Survey / assessor / authority record |
| Authority and approval route | — | Current agency page |
| Project type and scope | — | Written scope and code pathway |
| Required forms and drawing set | — | Current checklist and form revision |
| Fees and calculation date | — | Official fee schedule |
| Target review stages | — | Published service target, not a promise |
| Corrections, conditions and inspections | — | Portal or written authority record |
| Close-out evidence | — | Final approval / certificate / record |

**Project-use verification:** verify every form, fee and timing at the named authority on the submission date; generic guidance cannot confirm a project's requirements.

## Frequently asked questions

### What is a realistic plan-review timeline?

It depends on project size and department workload. A small tenant improvement may be reviewed over the counter in a day or cleared in a week or two; a mid-size commercial project often runs 3–8 weeks for the first cycle; a large or multi-agency project can take several months across multiple cycles. These are typical ranges only — the AHJ's published service standards and current backlog govern.

### What is the single biggest driver of a long timeline?

Resubmittal cycles. The first review is usually the fastest part; each round of corrections sends the set back into the queue and adds weeks. A complete, coordinated, code-anticipating submittal that clears in one or two cycles will beat a rushed set that loops four or five times, even if the rushed set was filed earlier.

### Can I pay to speed up review?

Often, yes. Many jurisdictions offer expedited or priority review for an additional fee, third-party plan review, or self-certification / professional-certification programs for eligible project types that shift the compliance attestation to a qualified design professional. Availability and eligibility vary — check whether the AHJ publishes an expedited program.
