Here’s a look at some of the foundational basics if you’re seriously considering a tiny house on wheels. From navigating the permitting process to ensuring everything is up to code, there’s a lot to consider—but you don’t have to do it alone. At Tiny House Big Love, we’re here to guide you through the journey, step by step, so you can focus on bringing your tiny house dreams to life.
So, you’ve got dreams of parking a charming Tiny House on Wheels (THOW) in your backyard—maybe as a cozy art studio, a rental unit, or even your own micro-home paradise. But before you hitch that dream to reality, there’s one big question to tackle: What permits do you need, and how do you get them?
Permitting a THOW can feel like navigating a labyrinth of local, state, and even federal regulations. To make it easier, we’re breaking down the process and covering the key types of permits you might need—whether you're in California, Texas, or anywhere in between.
Step 1: Define Your Tiny House’s Purpose
First things first: What are you using your THOW for? This is the foundation of everything. Local regulations don’t just care about the structure itself—they care about how you’re using it. Here are some common use cases and how they might affect permitting:
Residential Use: Planning to live in your THOW? This typically requires the highest level of compliance, including adherence to building codes and safety standards.
Accessory Dwelling Unit (ADU): If your THOW will serve as an ADU (a secondary living space on a property with a main home), it might need to meet specific ADU regulations.
Recreational Use: Using it as a weekend getaway or a guest house? Standards may be more lenient, but zoning still matters.
Non-Residential Use: Think art studio, yoga retreat, or home office. These uses often have fewer requirements but may still need zoning approval.
Pro Tip: If you start with a non-residential use (like an art studio) and later want to switch to residential, you’ll likely need to apply for a change of use permit. This involves meeting stricter safety and building standards.
Step 2: Know Your Local Zoning Laws
Zoning codes are the gatekeepers of where your THOW can legally sit. These regulations vary wildly from state to state, city to city, and even neighborhood to neighborhood. Here’s what to look for in your local zoning code:
Allowed Uses: Does your zoning district allow THOWs? If yes, under what conditions? Some areas treat THOWs as ADUs, while others classify them as recreational vehicles (RVs) or temporary structures.
Setbacks: How far does your THOW need to be from property lines, fences, or other structures?
Lot Size: Is there a minimum lot size requirement for placing a THOW?
Parking and Access: Are there rules about parking spaces or driveway access for your tiny house?
Screening Requirements: Some areas require THOWs to be hidden from street view or neighboring properties.
Pro Tip: Local planning departments are your best friend here. Don’t be shy—reach out to them with questions. They can clarify the zoning code and help you avoid costly mistakes.
Step 3: Understand Building and Safety Standards
Safety standards are non-negotiable, especially if your THOW will be used as a residence. While these standards vary by state, most places require compliance with one or more of the following:
ANSI Standards: The American National Standards Institute sets safety benchmarks for THOWs, covering everything from structural integrity to electrical systems.
RVIA Certification: If your THOW is classified as an RV, it may need certification from the Recreational Vehicle Industry Association.
State-Specific Codes: Some states, like California, have additional safety requirements for THOWs used as ADUs.
DIY Builders: If you’re building your THOW yourself, check with your local government about how to certify that it meets safety standards. Alternatively, purchasing a prebuilt or custom THOW from a certified builder can save you time and headaches.
Step 4: Explore the Different Permit Types
Depending on your location and planned use, you might need one or more of the following permits:
THOW Permit: For areas that recognize THOWs as their own category, this permit covers placement and use.
ADU Permit: If your THOW is being used as a secondary dwelling unit, you’ll need to meet ADU-specific rules.
RV Permit: If your THOW is classified as a recreational vehicle, it may fall under RV park or campground regulations.
Temporary Use Permit: For short-term uses, like a mobile office or event space, this permit might apply.
Step 5: Don’t Skip the Permitting Process
It’s tempting to skip the red tape and park your THOW without bothering with permits. But here’s the deal: Skipping permits can lead to fines, code enforcement actions, or even being forced to remove your tiny house. Not fun.
Instead, do the legwork up front. Research your local regulations, talk to your planning department, and, if needed, consult a land use attorney. It’s worth it to avoid headaches down the road.
Special Considerations for Different States
While the general principles above apply nationwide, each state has its quirks. Here are a few examples:
California: THOWs are often treated as ADUs, but local rules vary. For example, Los Angeles allows one THOW per lot as an ADU, while San Jose has specific setback requirements.
Texas: Regulations are more relaxed in rural areas, but urban zones often have stricter rules.
Florida: THOWs in hurricane-prone areas may need additional structural reinforcements.
Oregon/Washington: Known for being tiny house-friendly, but still requires compliance with local zoning and building codes.
Final Thoughts: Your Tiny House Dream is Worth It
Permitting a Tiny House on Wheels might seem like a daunting process, but it’s a crucial step to making your dream a reality. Whether you’re building it yourself or buying one prebuilt, taking the time to understand and comply with local regulations will save you time, money, and stress in the long run.
So, roll up your sleeves, do your research, and get ready to enjoy the big love that comes with tiny living. Your THOW adventure awaits!
