Introduction to ADUs

Accessory Dwelling Units (ADUs) have become increasingly popular among homeowners looking to maximize the utility and value of their properties. But what exactly is an ADU? An ADU, or Accessory Dwelling Unit, is a secondary housing unit on a single-family residential lot. These units can be detached, attached, or even converted from existing spaces like garages or basements.

The benefits of building an ADU are manifold:

  • Additional Income: Renting out an ADU can provide a steady income stream.
  • Family Accommodation: Perfect for housing elderly parents, grown children, or guests.
  • Increased Property Value: ADUs can significantly boost the value of your property.
  • Flexible Living: Offers more living space without the need for moving to a larger home.

Legal and Zoning Requirements in Pasadena

Before embarking on your ADU project, it's crucial to understand the legal and zoning requirements in Pasadena. The city has specific guidelines to ensure that ADUs are built safely and harmoniously within existing neighborhoods.
