Where Can I Put a Tiny Home in California? A Homeowner’s Guide

Introduction

As the demand for affordable and flexible housing solutions grows, tiny homes are at the top of the list for California homeowners looking to get the most out of their property. Whether you’re looking for multigenerational living, rental income or downsizing your lifestyle, knowing where you can put a tiny home is key. At Golden State ADUs, we help Northern California homeowners through the design, permitting and construction process from start to finish, so you can turn your tiny home dream into a reality.

The tiny house movement has gone national, offering a more intentional, minimalist and sustainable way of living. From temporary tiny homes used as flexible guest quarters to permanent tiny homes that are full-time residences, the appeal is maximizing your living space while minimizing costs. Tiny house enthusiasts are drawn to this lifestyle not only for the financial benefits but also for the freedom and simplicity it brings. And with the growing popularity of tiny house communities and backyard ADUs, the possibilities are expanding faster than ever.

Types of Tiny Homes and How They’re Classified in California

Tiny Homes on Foundations

Tiny homes on permanent foundations are treated like traditional accessory dwelling units (ADUs) in California. These homes must meet the 2022 California Residential Code, specifically Appendix AQ, which governs small dwelling units. They must have a minimum ceiling height of 7 feet 6 inches and at least one room of 120 square feet or more. This floor area standard ensures livability while maintaining safety.

Tiny houses on foundations are perfect for homeowners looking for long-term housing solutions, whether for rental income, family use or multigenerational living. Many tiny homeowners in cities like Sacramento, Elk Grove and Folsom are choosing this type of setup as a more manageable and affordable housing option compared to building a full-size traditional home.

Building a little house on a foundation also comes with the benefit of long-term durability and property appreciation. With the right building permits and compliance with local ordinances and safety standards, a tiny house in your backyard can become a valuable asset.

Tiny Homes on Wheels (THOWs)

Tiny homes on wheels, often referred to as THOWs or tiny houses on wheels, are classified as recreational vehicles. These mobile tiny homes must meet ANSI 119.5 standards set by the RV Industry Association to be legally recognized. While they offer flexibility and portability, THOWs are subject to zoning regulations that vary widely depending on location.

For many tiny house enthusiasts, the THOW is the ultimate in tiny living, a home that can travel while still offering the comforts of a permanent structure. But local zoning ordinances often determine if you can use a THOW as a primary residence. Some areas may treat them as temporary dwellings, while others allow them as ADUs with proper permits, utility access and skirting.

Living in a THOW can be a great option for those looking to try out the tiny house lifestyle or seeking short-term affordable housing with flexibility.

Where You Can Legally Put a Tiny Home in California

Allow Tiny Homes on Residential Property as ADUs

Thanks to California’s ADU legislation, most homeowners in residential zones can allow tiny homes on their property as ADUs. Whether it’s a tiny house on wheels or a foundation-based build, state law makes it easier than ever to add a tiny home to your existing property.

Cities like Sacramento, Folsom, and Citrus Heights have clear guidelines that allow backyard ADUs. Many tiny homeowners are taking advantage of these opportunities to create extra income, support aging parents, or provide space for college-aged children, all without having to buy land or invest in large-scale development.

By working with experienced tiny home builders like Golden State ADUs, you can streamline the process from securing a building permit to meeting all local building codes and local zoning ordinances.

Local Regulations Vary by City and County

Even with state law in place, local regulations play a big role in where and how you can place a tiny home. Each jurisdiction interprets state law differently and often adds its own layers of requirements.

Santa Cruz County, for example, allows one THOW per parcel and caps the size at 400 square feet. San Benito County requires skirting, utility hookups, and specific setbacks. These kinds of local rules make it essential to consult your local planning department or partner with a firm that understands county regulations and local zoning regulations.

Navigating these rules on your own can be time-consuming and confusing. Our team makes it simple, we stay current with changing ordinances and handle the details so you can focus on designing your dream space.

Tiny Homes in Rural Areas in California

If you’re looking to place a tiny home in rural areas, you’ll find more flexibility and fewer restrictions than in urban or suburban zones. In counties like Nevada, El Dorado, and Placer, there are zoning allowances that let you place a tiny home on large lots or agricultural parcels.

Rural areas are ideal for those who plan to use a tiny home as their primary residence and want more space, privacy, and freedom. Many tiny home communities and tiny home villages are emerging in these parts of the state, offering features like community gardens, dog parks, and shared amenities that elevate the experience of tiny living.

Whether you’re installing a permanent tiny home or starting with a mobile tiny home that later becomes stationary, rural counties are often more tiny home friendly, but it’s still important to get confirmation from local authorities before starting your project.

Minimum Square Footage Requirements

California’s building code includes specific minimum square footage requirements to ensure safety and livability. Appendix AQ requires at least one room to be 120 square feet, and other habitable rooms (excluding bathrooms and kitchens) to be at least 70 square feet.

Whether you’re building a tiny house on a foundation or placing a THOW as an ADU, these floor area requirements apply. Understanding these standards is key to getting the proper permits and staying compliant with safety standards.

At Golden State ADUs, we design every project to meet code without compromising on the functionality or beauty of your tiny home.

Tiny Homes in RV Parks

When local zoning doesn’t allow tiny homes on private land, another option is to put your tiny home in a licensed RV park. This is especially helpful for THOWs which are often regulated the same as recreational vehicles.

RV parks in California are starting to welcome tiny house enthusiasts and offer a mix of affordability and community. Many have shared amenities like laundry facilities, green spaces and recreational areas. Some even allow park model homes and trailers so you have more options.

This setup allows you to live on site without going through the full ADU permitting process, though you still need to follow local ordinances and park rules.

Park Model Tiny Homes as an Option

Park model homes also called park trailers are a popular option for tiny home living in California. Slightly larger than THOWs (up to 400 sqft) they offer a bit more comfort while still being considered mobile dwellings.

Though park models feel more like manufactured homes they’re technically classified as RVs and must be built to RVIA standards. This makes them perfect for RV parks, mobile home communities and retirement communities.

Like THOWs they may not be permitted on private property without going through local zoning and building approvals, but they are increasingly being used in tiny house communities throughout the state.

Are Park Models Legal in California?

Yes park models are legal in California, but their placement depends on how they are classified under local rules. Most commonly they’re allowed in RV parks or mobile home communities. On private land you’ll need to verify if your local ordinances recognize them as permanent residency.

Not sure if a park model or a traditional tiny home is for you? Golden State ADUs can help you decide which one is best for you based on your property, budget and long term plans.

What about El Paso County or Colorado Springs?

While Golden State ADUs focuses on California, areas like El Paso County and Colorado Springs are worth watching. Both have expanded zoning laws to support tiny home communities and individual dwellings, especially in rural areas.

El Paso County has even recognized tiny homes as legal primary residences in some zones, showing how flexible and inclusive zoning policies can support affordable housing. Their success stories are a good example of what we’re advocating for here in California.

Can I put a tiny home in National Parks?

Generally national parks do not allow private permanent dwellings like tiny houses. However, tiny homes may be used seasonally in support of park operations or staff accommodations.But not near Yosemite or the Blue Ridge Mountains.

Zoning and Building Code Considerations

Statewide ADU and Building Codes

California’s ADU laws make housing more accessible but don’t eliminate the need for compliance. Appendix AQ governs foundation based tiny homes, THOWs follow safety standards similar to RVs and manufactured homes.

Getting the right permits and understanding how your tiny home fits into state and local codes is crucial. We handle all the paperwork so your project is safe, legal and successful.

Local Zoning Layers and Custom Requirements

Every city and county adds its own layers to the rules. Some jurisdictions cap size, restrict certain features like composting toilets or require on-site utility hookups.

Even a well built little house can be delayed or denied without local approval. That’s why we work directly with local planning departments and building officials to handle zoning, inspections and approvals for you.

Common Mistakes to Watch Out For

State Law Trumps Local Zoning

While state laws support ADUs and tiny homes, local zoning laws control the details. Always check with your jurisdiction – or let us do it for you.

THOW is not a Permanent Structure

A tiny house on wheels may feel permanent but unless it meets zoning standards and is approved for residency it’s a mobile unit. Getting clarity on classification and usage rights is key.

Ignoring Utility and Foundation Needs

Even temporary homes need water, sewer and power. Permanent homes need a foundation that meets safety standards. Skipping these steps can mean costly delays.

FAQs: Where Can I Put a Tiny Home in California?

Can I Live In A Tiny Home Full-Time On My Own Land?

Yes, if zoning allows. Local regulations and tiny house laws determine whether a THOW or permanent unit can be a full-time primary residence. Make sure to check state and local tiny house regulations before moving in.

Do Tiny Homes Count As ADUs In California?

Yes. Both tiny houses on foundations and in many areas THOWs are ADUs under California’s ADU and tiny house laws. This makes them a great option for anyone looking to live full-time in a tiny house on their property.

What Counties In California Allow THOWs?

Nevada, Santa Cruz, and San Benito Counties have clear policies allowing THOWs as ADUs or standalone primary homes. These counties are also leading the way in community development by expanding housing options and tiny house regulations.

What Are The Minimum Lot Size Or Utility Requirements?

Varies. Some places allow tiny homes on small lots, others require full utility hookups and minimum square footage. Check with local zoning and building departments to ensure compliance with tiny house regulations and safety standards.

Is A Tiny Home More Affordable Than A Traditional ADU?

Yes, especially for smaller units and THOWs which are less expensive and faster to build. Tiny house living is not only budget-friendly but also a path to simpler, more sustainable homeownership.
