What Is An ADU?

Your Complete Guide to Accessory Dwelling Units (ADUs): Common Questions Answered

Accessory Dwelling Units (ADUs) have become a hot topic in recent years as homeowners explore ways to maximize property value, create additional living spaces, and even generate rental income. If you’re considering building an ADU, you likely have a lot of questions. Let’s dive into the most common questions and provide a comprehensive guide to help you get started.

An ADU, or Accessory Dwelling Unit, is a secondary, smaller residential unit located on the same property as a primary home. These spaces can serve a variety of purposes, such as housing for family members, a rental property, or even a private office or guest suite. They’re known by many names, including granny flats, in-law units, or backyard cottages.

How Much Does It Cost to Build an ADU?

The cost of building an ADU varies depending on factors like size, design, location, and construction materials. On average, homeowners can expect to spend anywhere from $100,000 to $400,000. Costs can increase if you’re adding luxury finishes or encountering significant site preparation needs.

What Are the Different Types of ADUs?

ADUs come in various forms to suit different needs and property layouts:

Detached ADUs: Standalone structures separate from the main house, often built in the backyard.
Attached ADUs: Units that share a wall with the main house but have a separate entrance.
Garage Conversions: Transforming an existing garage into a livable space.
Basement Conversions: Repurposing a basement to serve as an ADU.
Interior ADUs: Spaces created within the primary home, such as converting an attic or adding a second unit within the existing footprint.

Can I Convert My Garage into an ADU?

Yes, converting a garage into an ADU is a popular and cost-effective option. It utilizes existing structures, which can lower construction costs. However, this process requires meeting local building codes, ensuring proper insulation, and possibly upgrading utilities like plumbing and electrical systems.

What Are the Size Limitations for ADUs?

Size limitations depend on local zoning regulations. Generally, ADUs range from 400 to 1,200 square feet. Some areas set maximum sizes as a percentage of the primary home’s square footage. Be sure to check with your local planning department for specific rules.

Do I Need Separate Utilities for an ADU?

While separate utilities aren’t always required, they can provide greater flexibility, especially if you plan to rent out the unit. Installing separate meters for water, electricity, and gas might increase upfront costs but could simplify billing and tenant management in the long run.

What Are the Local Regulations Regarding ADUs?

Local regulations vary widely. Factors like setbacks, height restrictions, parking requirements, and owner-occupancy rules can all impact your project. Additionally, some areas may have streamlined processes for ADU approval to encourage development. Researching your city or county’s ADU policies is an essential first step.

How Do I Get Started with the Permitting Process?

The permitting process begins with contacting your local planning or building department. Here’s a general outline of what to expect:

Research Local Zoning Codes: Understand the specific requirements for ADUs in your area.
Create a Design Plan: Work with an architect or designer to draft a plan that meets your needs and complies with local codes.
Submit Permit Applications: File the necessary applications, which may include building permits, zoning permits, and utility permits.
Address Feedback: Respond to any comments or requests for changes from local authorities.
Begin Construction: Once permits are approved, you can start building your ADU.

ADUs offer numerous benefits, such as:

Providing additional living space for family or guests
Generating rental income
Increasing property value
Offering a flexible solution for multi-generational living
