Homeowner Mr. Wang: “I just want some ‘simple decorating’ this time, no structural changes, just new wallpaper and some custom cabinetry.” The designer nodded, provided an estimate, and both parties happily signed the contract. A few weeks later, Mr. Wang had a sudden idea: “Oh, by the way, could you knock down the wall in my study and make it open-plan? And redo the ceiling too.” The designer looked troubled: “Mr. Wang, that’s no longer just ‘decorating’; it’s ‘interior renovation,’ which requires a permit.” Mr. Wang was confused: “It’s just adding one more item, why does it suddenly cost more and involve extra procedures?”
Meanwhile, his neighbor, Mrs. Li, directly told her general contractor: “I want to ‘completely remodel’ this old house!” The contractor patted his chest confidently: “No problem, ‘remodeling’ is our specialty!” So, they proceeded with knocking down walls, altering room layouts, and rebuilding ceilings. However, Mrs. Li was unaware that what the contractor called ‘remodeling’ legally constituted an act of ‘interior renovation’ requiring a permit. Since the contractor lacked a legitimate license, they deliberately used ambiguous terms, subtly shifting all the risks of non-compliance onto the homeowner.
‘Decorating,’ ‘renovating,’ and ‘remodeling’ – these three terms we use casually in daily conversation seem similar, but within the strict framework of building regulations, they are worlds apart. Confusing them isn’t just a communication misunderstanding; it’s a significant legal risk. This isn’t merely a word game; it’s a crisis that’s blurring homeowners’ rights. The core of this article is to plainly explain the **’legal definitions of decorating, renovating, and remodeling’** for you, enabling you to understand the devil in the details of contracts and quotes.
The crux of the issue is: **the law recognizes ‘actions,’ not ‘nouns.’** Whether your contract with the designer states ‘decorating project’ or ‘renovation project’ is meaningless to the building department. They only care about ‘what you did.’ This creates a vast disconnect between colloquial usage and legal boundaries.
In Article 3 of the ‘Regulations for the Management of Interior Renovation of Buildings,’ the law provides a very narrow definition, which we can call ‘decorative’ actions. You can think of ‘decorating’ as ‘surface beautification that doesn’t involve structural work.’
For example, well-known brands like **IKEA** or Taiwan’s **HOLA**, primarily offer ‘decorating’ services. Purchasing custom cabinetry, kitchen units (without altering plumbing), curtains, replacing flooring (non-adhesive), painting, or wallpapering… these actions, because they **do not involve** changes to ceilings or partition walls, are classified as ‘decorating’ or ’embellishment.’ Legally, they **do not require** an interior renovation permit. This is the root of why most homeowners mistakenly believe ‘decorating’ never needs a permit.
The term ‘remodeling’ is the biggest legal trap. For many old house renovation projects, such as those featured on shows like **HGTV’s ‘Fixer Upper’** or design blogs, homeowners often say, ‘My old house needs a remodel.’ In common parlance, ‘remodeling’ implies ‘a complete overhaul,’ naturally including ‘demolishing partitions,’ ‘rewiring,’ and ‘rebuilding ceilings.’
But here’s the key: **Nowhere in the ‘Building Act’ or the ‘Regulations for the Management of Interior Renovation’ will you find the word ‘remodeling’!**
This is a term in a ‘legal vacuum.’ Unscrupulous general contractors love to use this word because it sounds professional but absolves them of ‘interior renovation’ legal responsibilities. They will deliberately write ‘old house remodeling project’ on the quote, but the actual work performed is 100% ‘interior renovation.’ If reported, the homeowner, holding this contract, cannot hold the contractor accountable because the contractor can argue, ‘I was just doing ‘remodeling’; the homeowner asked me to remove walls.’
Since ‘decorating’ has a narrow scope and ‘remodeling’ doesn’t exist in the regulations, who is the real legal protagonist? The answer is **’interior renovation.’** This term has supreme and strict definitions in Article 77-2 of the ‘Building Act,’ which clearly delineates the lines between legal and illegal.
According to regulations, if your property is in a building ‘open to the public’ or a ‘residential building of 6 floors or more,’ your project falls under **any of the following conditions**, and you **must** apply for a permit:
This is precisely why, as soon as Mr. Wang mentioned ‘removing the study wall and redoing the ceiling,’ the designer immediately warned him. This action escalates from ‘decorating’ to ‘interior renovation.’
Therefore, the legal distinction is very clear. We can summarize it as:
A simple determining question: ‘Decorating’ is about aesthetics; ‘interior renovation’ involves altering ‘structures.’ And ‘remodeling’? That’s contractor jargon; legally, it’s closest to ‘interior renovation.’
As a new homeowner, you don’t need to memorize legal statutes. You simply need a clear ‘dashboard’ to instantly assess whether the person you’re communicating with is professional or hiding risks when discussing with your designer or contractor. The following table is your best defensive tool.
This is the most crucial step. Mentally check: Does my project involve ‘removing walls’? Does it involve ‘building walls’? Does it involve ‘rebuilding the ceiling’? If the answer to **any of these three questions is YES**, then it is 99% ‘interior renovation.’ Don’t let them package it as ‘decorating’ or ‘remodeling.’
‘Decorating’ disputes typically fall under the scope of the ‘Consumer Protection Act’ (e.g., regarding materials, colors, or timelines). However, ‘interior renovation’ disputes directly violate the ‘Building Act’ and fall under **public law**, which can result in government orders to halt work, fines, or even criminal charges.

Ambiguity in language is a breeding ground for risk. Once you clarify the fundamental difference between ‘decorating’ and ‘interior renovation,’ you regain the initiative to protect your property’s safety.
You can choose to continue using vague colloquialisms (‘I’ll just do some casual decorating’) and hope you don’t encounter unscrupulous operators; or, starting today, you can precisely ask: ‘Does my project involve ‘interior renovation’ as defined by the Building Act? Do you possess the legal interior renovation license required to apply for the permit on my behalf?’
Your choice determines whether you sign an ‘aesthetic contract’ or a ‘legal minefield’ fraught with potential fines and demolition risks.
