Building Officials & Municipalities
How three construction approaches compare
| Typical site-built permit | Pre-approved plans (site-built) | ICC Accelerator | |
|---|---|---|---|
| Who designs the home | Owner hires an architect/designer | Jurisdiction commissions plans or architects list them | Manufacturer — plans already drawn |
| Who pays for design | Owner | Jurisdiction, consumer or builder (per-use fees) | Manufacturer |
| Building plan review | Full review by your department | Reviewed once by your department; reused within your jurisdiction | Approved for specific conditions under the state off-site program with delegated ICC NTA review |
| Where the plan can be used | That project only | Your jurisdiction only | Conditions in the state in which it is approved |
| Catalog growth | N/A | Only when you commission or accept new plans, obsolete with code update | Grows as manufacturers add and maintain plans for additional locations |
| What the owner needs to build | Find, vet and negotiate with an architect and a builder | Find, vet and negotiate with a builder | Pick a plan — manufacturer and builder network connected on selection |
| Your review | Building plan, site plan, zoning | Site plan, zoning | Site plan, zoning |
| Your site inspections | Foundation, framing, rough-ins, insulation, final | Foundation, framing, rough-ins, insulation, final | Foundation and final |
| Construction sequence | Sequential, on site, weather-dependent | Sequential, on site, weather-dependent | Factory build and site work in parallel |
| Code basis | Locally applicable code | Locally applicable code | Locally applicable code |
| Hosting | N/A | You build and maintain a web page | Link to the ICC portal, or a white-labeled page for your jurisdiction |

Support residents
Provide residents with access to reviewed, code compliant plans and the qualified providers that can deliver them efficiently.
Streamline plan review
Leverage plans previously reviewed by ICC-NTA through your state’s off-site construction program to cut review times and staff burden.
Each plan lists the states where it has been reviewed. A site with different snow, wind, seismic or wildfire requirements may need a revised version of the plan, which the Provider can have adapted and reviewed by ICC-NTA through the state off-site construction program.
