Does Anyone Know If There Are Any States Where Permits Are Not Required on ADUs
Posted by Peter on May 12, 2024 at 4:00 pmDo all states or counties in states require permits on Accessory Dwelling Units often referred to as ADUs? I like to put an accessory dwelling unit for additional rental income due to bidenomics and the out of control inflation and cost of living.

In the United States, almost all states require some form of permitting for building accessory dwelling units (ADUs). There are no states that categorically do not require permits for the construction of ADUs, as building and safety regulations are critical to ensuring the structures are safe and compliant with local codes.
However, the ease of obtaining a permit and the specific requirements can vary widely from state to state and even within different municipalities within a state. Here’s how it typically works:
State Legislation and Local Control:
- State Laws: Some states have passed legislation to make it easier to build ADUs in response to housing shortages. For example, California has enacted laws to streamline the ADU permitting process across all its cities and counties.
- Local Jurisdictions: Despite state laws, local governments (cities and counties) often have the authority to set specific zoning requirements, building codes, and permitting processes. This means the ease of obtaining a permit can vary significantly even within a single state.
Streamlined Processes:
- Some states and municipalities are actively working to streamline the process for ADU permits to encourage more homeowners to build these units. This can include reduced fees, pre-approved plans, or by-right approval processes that minimize bureaucratic delays.
General Permit Requirements:
- Building Permits: Required to ensure the ADU meets state and local building codes.
- Zoning Permits: Ensure the ADU complies with local land use and zoning regulations.
- Other Specific Permits: Depending on the location, you might also need electrical, plumbing, or mechanical permits.
Recommendations:
- Check Local Regulations: Always check with your local city or county building department for the most accurate and up-to-date information on ADU regulations and permit requirements in your area.
- Consider State Laws: Be aware of state laws that may impact ADU development. States like Oregon, Washington, and California have specific laws intended to promote ADU construction.
- Consult Professionals: Consider consulting with a local architect, builder, or land use attorney who can provide guidance tailored to your specific situation and location.
While there is no blanket exemption from permits for ADUs in any state, the process and complexity of obtaining those permits can vary significantly. The trend in many states is towards making it easier to build ADUs as a way to address housing shortages, but compliance with local regulations is always necessary.

There are a few states in the United States that have relaxed or eliminated building permit requirements for certain types of accessory dwelling units (ADUs) in order to encourage their construction. However, it’s important to note that specific requirements can vary significantly not only by state but also by city and county within each state. Here are some examples of states that have loosened ADU permit rules:
- California: In 2020, California passed new laws making it easier to build ADUs without a permit in many cases. ADUs under 500-800 sq ft that meet certain conditions are exempt from permits in most cities.
- Florida: Florida has exempted ADUs under 1,000 sq ft from permit requirements statewide if they meet the state’s building code. Local jurisdictions cannot require permits for these units.
- New Hampshire: Detached ADUs under 700 sq ft are exempt from local permits and building code requirements in New Hampshire.
- Vermont: Vermont allows one ADU per owner-occupied home to be built permit-free as long as it meets basic safety requirements outlined in state law.
- Oregon: Portland and several other Oregon cities have waived permit requirements for ADUs under 600-800 sq ft to promote their construction.
However, even in these states, larger ADUs, attached units, or those not meeting the specific conditions generally still require permits from the local municipality. Additionally, some states and localities may require permits for certain aspects of the ADU construction, such as electrical or plumbing work, even if an overall building permit is not required.
It’s important to note that permit exemptions are typically quite narrow and come with specific size and construction requirements. Therefore, it is advisable to check the latest ADU laws and regulations with your city, county, and state before proceeding without permits to ensure compliance.

To date, laws broadly allowing homeowners to build ADUs have passed in eight states, and ADU bills have been introduced in several others1. However, the specifics of permitting and regulations can vary significantly from state to state.
To date, laws broadly allowing homeowners to build ADUs have passed in eight states, and ADU bills have been introduced in several others. However, the specifics of permitting and regulations can vary significantly from state to state.
For example, in California, a statewide law changed ADU owner occupancy requirements in 2022 so that ADUs built before 2020 or after 2025 would not be subject to owner-occupancy requirements. In 2020, California also introduced legislation that exempts certain ADUs from the planning stage.
In New Hampshire and Maine, laws require that local zoning allow for ADUs but do not require by-right approvals. A 2020 Vermont law does require by-right approvals but also allows communities to impose occupancy restrictions and parking requirements.
It’s important to note that even in states where ADUs are broadly allowed, local zoning laws and building regulations may still apply, and permits may be required depending on the specifics of the project. Therefore, it’s always a good idea to check with local authorities before starting an ADU project.

Most counties throughout the United States require permits for building an in-law suite, ADU (accessory dwelling unit), or tiny home on your property. Here are some key points to consider:
Permit Requirements:
-
Building Permit: This permit ensures that the structure meets building and safety codes. It often requires submitting plans that detail the design, layout, and specifications of the structure.
-
Zoning Permit: This confirms that the construction complies with local zoning laws, which govern land use, setbacks, occupancy limits, and more.
-
Trade Permits: If electrical, plumbing, or mechanical work is needed, separate trade permits are typically required.
Variations Across Counties:
- County-Specific Rules: The requirements vary based on local zoning and building codes. Some counties may have more lenient rules for certain areas or neighborhoods, while others have stricter standards.
- Municipal Regulations: In addition to county requirements, cities may impose their own regulations, adding another layer of rules to follow.
Key Considerations:
- Usage: Whether the ADU or tiny home will be used for family members or rented out can affect the permit requirements.
- Setbacks and Lot Size: Counties often specify minimum setbacks from property lines and the primary dwelling, as well as lot size requirements.
- Building Codes: The structure must meet Florida Building Code standards, ensuring safety and habitability.
- Impact Fees: Some counties charge impact fees to account for the additional strain on infrastructure.
Recommendations:
- Consult Local Authorities: Before starting construction, contact your local planning or building department to understand specific requirements.
- Review Zoning Codes: Check zoning maps and regulations to verify if your property qualifies for an ADU or tiny home.
- Professional Advice: Engage with architects, builders, or land use consultants who are familiar with local permitting processes.
In summary, almost all Florida counties require permits for ADUs, in-law suites, and tiny homes. The exact requirements depend on local regulations, and understanding these details is crucial for compliance and avoiding future issues.
