Alas, do you know? Last month, Lao Wang, who spent 200,000 yuan to install the outdoor large screen next door, was sealed by the urban management after three days of lighting up - just because he didn't understand this thing, he had to approve it first! Let’s talk about this today, so that you can avoid detours.

Three major pitfalls in the approval process

I have seen too many people fall into the trap of "think you don't need approval". Last year, 37 LED screens in a third-tier city were forced to demolish due to incomplete procedures, and the direct economic losses exceeded 8 million yuan. Here is a key understanding:​ ​As long as the screen size exceeds 3㎡, or is installed on the facade of the building, 99% of the cases require approval.​​。

Scenario decision approval route

First figure out where your screen is to be installed:
▎​​Outdoor advertising category​ ​: For example, the advertising screen on the exterior wall of the mall
• Requires: Municipal Approval Document + Outdoor Advertising Registration Certificate
• Time to take: The average 28 working days in first-tier cities (about 15 days in second- and third-tier cities)
▎​​Building facade category​ ​: Fence screen like a stadium
• Essential: Structural Safety Certificate of Housing and Urban-Rural Development Bureau + Fire Protection Acceptance Document
• Special note: The load calculation error must be <5%
▎​​Temporary activities​ ​: Concert floor tiles and screens
• Key: Cultural department filing + site use license
• Time limit: Usually declare 7-15 days in advance

Complete list of application materials

Prepare these to save at least 5 errands:

1. ​​Certificate of subject qualification​ ​: Copy of the business license (stamped with official seal)
2. ​​Technical Parameters Table​ ​: Must include screen size, brightness range, and installation method
3. ​​Structural calculation book​ ​: Find a qualified testing agency to issue it
4. ​​Effect simulation diagram​ ​: The distance parameters to the surrounding buildings need to be marked
5. ​​Light pollution assessment​ ​: Especially for screens used at night

There is a detail here that is easy to miss - a brand was called back and retried for two weeks because it did not write down the refresh rate in the parameter table (single notes above 1920Hz).

Self-question: Common confusion solved

​​Q: Is it necessary to apply if I install a small screen at the door of my own store? ​ ​
A: As long as you are outside the building red line, even if it is only 2 square meters, the procedures must be completed. There is a case: A 1.8㎡ menu screen installed in a milk tea shop in Hangzhou was fined 8,000 yuan for not reporting.

​​Q: Can rural areas be managed loosely? ​ ​
A: Quite the opposite! Nowadays, the approval of many county towns is stricter than that of big cities. For example, a town in Jiangxi issued a new regulation last year: all LED screens must be connected to a brightness control system (this function is now available in many high-end screens).

​​Q: Can I get it done once and for all after approval? ​ ​
A: Pay attention! The validity period of outdoor advertising approval documents is usually 2 years, and must be applied for renewal 3 months before expiration. There is a data: about 12% of screens per year are punished for not renewing due to expiration.

Cost avoidance guide

Don't be deceived by these hidden costs:
• ​​Structural reinforcement fee​ ​: Installing screens in old buildings may be more expensive than the screen itself
• ​​Annual inspection fee​ ​: Most cities require safety inspections once a year (the market price is about 200 yuan/㎡)
• ​​Light pollution control deposit​ ​: Some cities charge a deposit ranging from 5,000 to 20,000 yuan

There is a tip for saving money: choose to bring​ ​Automatic brightness adjustment​ ​The screen can reduce the environmental impact assessment cost by more than 30%. For example, some high-end models can be automatically adjusted to 800-1200cd/m² according to ambient lighting, which is a bonus point that can be written in the application materials.

Editor's opinion

Policy has been significantly tightened in the past two years. For example, Shenzhen incorporated LED screen approval into the smart city management system last year. It is recommended that everyone do two things before purchasing: ① Find the seller to ask for it​ ​Pre-approval guidance services​ ​ ②Check out the latest local "Outdoor Electronic Display Device Setting Specifications". Remember, the time spent on approval preparation is much more cost-effective than being fined afterwards!
