Bathroom and Remodeling - 101

Did you know that there are some places in the US where before you can hammer a nail into a wall you first need the equivalent of an encyclopedia’s worth of permits? Why? Because in the bureaucratic world of paper-pushers red-tape is their life drive. Folks love crossing all the Ts and dotting all the Is. But there’s a reason for their madness. Any remodeling you do, whether its internal or external has a level of risk attached to them. Are you taking into account that low-bearing wall? Did you know that your place has significant historical value? Is your contractor qualified? Does your team have insurance? Did you even look at the HOA guidelines? That and a dozen more factors are analyzed when it comes to giving you a permit — and, although it might seem like an eye-gouging experience, the whole ordeal is there to protect your property. And its value. And your well-being, and your community’s well-being. In this article we’re going to delve deep into bathroom remodeling and not only whether or not you’ll need a permit, but how to get one and why. 

Booting the price of your property 

According to Zillow for every buck you spend on a bathroom remodeling - a minor cosmetic job - you get $1.71 in return. That’s over 71% in ROI. And we’re not talking expensive refurbishing but simple aesthetic fixes or add-ons. For example, installing a combination grab bar and product holder. Or buying a bamboo shower seat. 

According to the National Association of REALTORS Research Group bigger refurbishes mean bigger bang for your buck — they significantly increase your property's value. Updating a powder room or installing new tiles before a sale will not only recoup the full amount you spend but it can also get you a 102% return. In other words, twice your investment plus a change. 

This is one of the reasons why bathroom remodeling has surged in popularity — rapidly becoming a top priority for many homeowners. Homeowners not only seek to enhance their living spaces but want to make their property’s value skyrocket. According to recent industry data, bathroom remodels are among the most sought-after projects, with an estimated 81% of folks expressing their intent to remodel their bathrooms. 

The allure of a modern, functional, and stylish bathroom is part of the attractive allure. Everyone wants something new. Something that will make their bathrooms shine. Why? Studies show that during life we spend over 1 year in the bathroom. From shower time to shaving time, to using the facilities, to drying out hair, to brushing our teeth, to applying makeup, to moisturizing, to cleaning the bathroom, we spend a lifetime in that place. Whether it’s actually using it, or simply checking our mails and our social feeds in our favorite throne room, we like to wallow away in our bathrooms, so we might as well spruce them up. 

As such, it's important not to overlook the regulatory aspects that come with such projects. You simply can’t dive into it. This comprehensive guide is designed to equip you with the knowledge you need to navigate the intricate landscape of permits when embarking on a bathroom remodeling journey.

Understanding Building Permits

Building permits are the cornerstone of responsible construction and renovation. They are there to protect you, your investment and your standing in the community. At their core, they are sort of like getting health insurance — you’ll be happy you went through the hassle the very second you need it. They are official documents issued by local authorities that grant you permission to undertake changes to your home. These permits ensure that the work is carried out in compliance with safety codes, zoning regulations, and building standards. While acquiring permits might seem like a bureaucratic red tape nightmare, they play a vital role in safeguarding the structural integrity of your home and the safety of its occupants.

Factors Influencing Permit Requirements

Several crucial factors influence whether you need permits for your bathroom remodeling endeavor, let’s dig into them:

  • Scope of the Remodeling Project: The extent of the changes you plan to make, whether they're minor or involve significant structural modifications, will determine the need for permits. There’s a difference between changing tiles and blowing out a wall, than there is with installing a new shower head.
  • Local Regulations and Building Codes: Different municipalities have unique regulations. It’s important to understand that what the city of Albuquerque needs differs from the minefield of regulations that Prague might require. Why? Each city is different. There are factors to consider like weather, soil, historical significance of properties, and dozens more. Familiarize yourself with your local building codes to understand the specific permit requirements applicable to your area.
  • Structural Changes vs. Cosmetic Upgrades: Cosmetic changes such as repainting or replacing faucets might not necessitate permits. However, any alterations that impact the structure of your bathroom could trigger permit requirements.
  • Plumbing and Electrical Work: Projects involving plumbing changes and electrical work typically demand permits due to the potential safety hazards associated with these modifications. These are critical because getting a permit might in fact end up showing you a red-flag that the constructor didn’t take into account. Think of them as an extra layer of defense. 
  • Environmental Impact and Sustainability Initiatives: If your remodel incorporates eco-friendly features or sustainability initiatives, additional permits might be required to ensure compliance with environmental regulations. They might also be necessary if you’re later going to apply for tax-rebates. Certain eco-friendly communities give their Greenpeace-loving neighbors a big pat on the back - in the form of less taxes - whenever they undertake an eco-friendly refurbishing.

Types of Bathroom Remodeling Projects and Permit Requirements

Minor Cosmetic Changes

Minor cosmetic changes are those that involve direct replacements or enhancements without altering the fundamental structure or safety of the bathroom. These changes often include painting, replacing fixtures, or upgrading hardware. In many cases, permits are not required for these types of changes as they are considered to have minimal impact on the overall layout and safety of the space.

Moderate Renovations

Small to medium bathroom renovations involve more substantial changes than cosmetic upgrades. We are talking about installing a new bathtub or shower, or changing the layout within existing plumbing lines, or replacing a bathroom vanity. Permits are a bit in the gray area when it comes to them. It all depends on the complexity of these modifications and the impact they have on the home’s overall infrastructure — permits might be necessary to ensure compliance with building codes and safety standards.

Major Renovations

For major bathroom renovations that encompass significant structural changes, such as altering plumbing lines, modifying load-bearing walls, or expanding the bathroom's square footage, obtaining permits is essential. These are do or die. You simply can’t skip them. These are the big projects you simply can’t fly under the radar — folks will notice when a work crew pulls up to your driveway. Not only that, any constructor worth his salt will either demand permits or in some cases even take care of the paperwork themselves. These projects can have far-reaching implications - they are incredibly complex - for the integrity of the entire home. These types of projects make it imperative to adhere to permitting requirements and undergo inspections to ensure safety and compliance.

Steps to Obtain Bathroom Remodeling Permits

Look-up Local Building Codes and Regulations

Begin by researching and going deep into the building codes and regulations specific to your location. Consult your local Department of Buildings or relevant authority to gather information about the necessary permits for your project. Each region has its own set of laws — so if you’re planning a big project, get your paperwork in order. 

Contact the Local Building Department

Engage with your local building department to discuss the details of your project. They can provide invaluable insights into the required permits, guide you through the application process, and specify any documentation they need. Also contact your HOA - if you have one - sometimes they can help out by giving you a key understanding of the whole ordeal. Plus, depending on how strict your HOA is, you might also need to inform them of your project. 

Prepare Necessary Documents and Plans

Compile all the essential documents for your permit application. This may include detailed plans of the proposed changes, plumbing and electrical layouts, and any other relevant information. Clear and accurate documentation is crucial to expedite the approval process. Depending on the type of service you acquired - whether or not you hired a competent construction company, or you’re going into it in a DIY fashion - some companies might take the baton and get you those permits on their own. 

Submitting the Permit Application

Thoroughly complete the permit application —  make sure and double-check that all required information is provided accurately. You will get, in most cases, a second chance to resubmit your work, but it will take time and effort. So it’s better to get it right the first time around. Be prepared to provide all sorts of details about the scope of work, materials, and estimated project timeline. In a permit’s case it’s better to have more paperwork than less. Pun intent: toss everything plus the bathroom sink at it.

Paying the Permit Fees

Permits are typically associated with fees that vary based on the scope of the project and your geographical location. Incorporate these fees into your remodeling budget to avoid surprises. Also, read the fine print, the devil is in the details — in some places eco-friendly or necessary remodeling for health reasons doesn’t pay fees. 

Waiting for Approval and Potential Modifications

After submitting your application, the building department will review it. Sometimes it might take less but normally as is the case with many governmental issues expect them to take their time. Depending on the complexity of your project and the workload of the department, this process might take a while. Don’t get frustrated if you see the days and even weeks pass. It’s all part of the process. Be patient and be open to making modifications to your plans if they don't align with code requirements.

Case Study on bathroom remodel — when you need a permit

Let’s do a case study - real-world example - of when you might need a permit for a bathroom remodel or refurbishing. It’s important to note that each region and municipality has different requirements and guidelines. For example, NYC is extremely strict, everything aside from painting, plastering, installing new cabinets, and resurfacing floors requires a permit – and failure to do so might land you a 25K fine. Meanwhile, Miami is more lenient and as long as you’re not installing a water heater or doing major renovations you don’t need a permit. 

Let’s look at Buffalo, New York and when you might need one.

A Building Permit is not required for certain types of construction, such as detached structures, playground equipment, swimming pools with shallow depths, fences, retaining walls  - unless supporting specific substances -, temporary stage sets, window awnings, partitions, finish work, listed portable equipment replacement, and minor repairs.

So, for example, if you need to install new wall tiles, or lightning, or fix a plumbing issues - toilet, sink, tub - you won’t need a permit. As long as those fixtures stay in the same location. 

Now, if you’re doing one of the following you will need to pay a fee and get your permit: 

  • Adding a sink or moving the one you already have.
  • Drastically changing the bathroom’s footprint — something even as small as building a dividing wall. 
  • Moving plumping around, for whatever reason.
  • If you’re undergoing a renovation and need equipment - like a dumpster out in the street.
  • Replacing a water heater.
  • Adding a window, expanding the current one, or installing a skylight. 
  • Adding new electrical outlets.
  • Waterproofing – you MAY need one.
  • Replacing a bathtub.

The rule of thumb on a bathroom remodel is that if you need to open or penetrate the walls, you will likely need a permit.
