San Diego is a popular destination for homebuyers, and there are many neighborhoods and communities throughout the city that offer homes with granny flats or guest houses.

A granny flat is a self-contained living space that is typically located on the same property as a single-family home. It is designed for an older family member who wants to live independently but also wants to be close to family. A granny flat may also be used as a rental property to generate additional income.

A guest house, on the other hand, is a separate dwelling on a property that is designed to accommodate guests. It is typically larger than a granny flat and may have multiple bedrooms and bathrooms. Guest houses are often used for short-term rentals, such as vacation rentals or Airbnb properties.

While there are some similarities between granny flats and guest houses, the main difference is their intended use. Granny flats are designed for long-term living and are usually occupied by a family member, while guest houses are intended for short-term rentals and are often occupied by tourists or other visitors.

The size of a granny flat, also known as an accessory dwelling unit (ADU), can vary depending on a few factors, such as local building codes, available space on the property, and the intended use of the unit.

Generally speaking, granny flats can range from around 300 square feet to over 1,000 square feet. However, the most common size is between 500 and 800 square feet.

Some granny flats may consist of just one room with a bathroom and a small kitchenette, while others may have several rooms, including a bedroom, living area, kitchen, and bathroom.

It's worth noting that the size of a granny flat doesn't necessarily determine its functionality or livability. With smart design and efficient use of space, even a small ADU can provide a comfortable and functional living space.

The size of guest houses can vary widely, depending on various factors such as location, purpose, and available space. Generally, guest houses are smaller than hotels and typically have fewer rooms. Some guest houses may only have a few rooms or suites, while others may have several dozen.

The size of a guest house may also depend on its intended use. For example, a guest house designed for couples or solo travelers may have smaller rooms than a guest house intended for families or groups. Additionally, guest houses located in urban areas with high land costs may have smaller footprints than those in rural or suburban areas.

Overall, the size of a guest house can range from a small cottage or studio apartment to a larger building with multiple rooms and amenities.
