Are Accessory Dwelling Units (ADUs) Allowed in Auburn? What to Know

Across the U.S., Accessory Dwelling Units (ADUs)—also called guest houses, in-law suites, or garage apartments—are growing in popularity. Homeowners add them to provide space for family, generate rental income, or boost property value.

But what about Auburn, Alabama? Can you build an ADU here? Let’s break it down.

What is an ADU?

An Accessory Dwelling Unit is a smaller, independent living space located on the same property as a single-family home. ADUs can be:

A basement or attic apartment
A garage converted into living space
A detached guest house or cottage
A separate unit attached to the main home

Auburn’s Zoning and ADU Regulations

Whether or not you can build an ADU depends on local zoning laws. In Auburn:

Certain residential zones allow secondary living units under specific conditions.
There may be size restrictions (usually a percentage of the main home’s square footage).
Parking requirements often apply if the unit will be rented out.
ADUs may need to meet Auburn’s building codes for plumbing, electricity, and safety.

Since rules vary by neighborhood, it’s best to check with the City of Auburn’s Planning Department before making plans.

Benefits of Having an ADU

Extra Income: Rent it out for long-term tenants or visiting students.
Family Flexibility: Provide space for aging parents or adult children.
Property Value: Homes with ADUs often attract more buyers.
Lifestyle Options: Use it as a private home office, art studio, or guest retreat.

Challenges to Consider

Cost: Building or converting space into an ADU can be expensive.
Permitting: The approval process may take time, especially if variances are needed.
Maintenance: You’ll need to manage upkeep just like any other rental or living space.
Neighborhood Rules: Some HOAs in Auburn may restrict or prohibit ADUs.

Final Thoughts

ADUs can be a fantastic investment for Auburn homeowners—but only if they’re allowed by zoning and built to code. Before you start designing a guest house or rental unit, make sure you understand the local requirements.
