Frequently asked questions

How to expand your house?

If your home no longer meets your needs but you and your family would rather not move, a home addition project may be just what you need. Here are some options to consider if you’ve been thinking about investing in a house addition in San Diego.

  • Go with a bump-out. If adding a whole floor or room to your home is not a viable option for you, a bump-out house addition may be the perfect solution. For instance, you might have a small kitchen that needs just about 40-50 extra square feet to become a fully functional and comfortable space.
  • Opt for a full house addition. This type of house addition is the most popular option among San Diego homeowners, despite being the most time-consuming and expensive of the lot. This is because a full home addition can add substantial resale value to your home, whether you decide to get a new garage, master bedroom, or dining room.
  • Convert a room. If you have an extra attic or garage that you don’t use for anything other than storage, converting this space into a more useful room may be a good choice. You can choose to convert your unused room into a craft room, bedroom, or workshop and get that extra square footage and functionality.
  • Build a sunroom. Sunrooms are typically unheated spaces made up of large windows that enable you to enjoy the feeling of being outdoors from the comfort of your home. Sunroom house additions are highly versatile and relatively easy to install as they don’t need any additional cooling or heating routing.
  • Go big with an ADU. Whether you’d like to have extra renting space or a starter property for your kids, adding an accessory dwelling unit is a great idea. You can choose to add a detached garage with a rented apartment above or create a modern backyard cottage as a convenient space for your close family.

What is considered an accessory unit?

An accessory dwelling unit or ADU is a term used to describe an additional, or secondary home that is built within or adjacent to a primary residence. Some examples of ADUs include guest houses, office rooms, detached garages, and similar house additions.

If you’ve been thinking about improving upon your San Diego home with an ADU construction, you’ll first have to check if you’d be able to add onto your home. As municipal and city permitting requirements and zoning ordinances can sometimes get in the way of these types of house additions, it is essential that you consult with our architects, builders or zoning office to check if an ADU would be doable.

Whether you need more information on ADU building or house addition services or wish to entrust the construction process to experienced contractors in San Diego, Lars Room Additions is your best choice. Let us add value, beauty, and functionality to your residence – contact us today.

What are the types of accessory dwelling units?

You could use the term accessory dwelling unit to describe a wide range of house addition projects. Here are some popular types of ADUs:

  • Backyard rooms: This type of ADU is great to have in your backyard as a quiet space to relax, read, and enjoy some quiet time.
  • Hobby rooms: In some cases, San Diego homeowners want to take up or go back to an old hobby they used to enjoy. These ADUs can be custom made to fit that need.
  • Office rooms: Offices are making a huge comeback in homes and outside of homes. If you need some quiet time in a productive space, an outdoor office ADU can be the perfect solution to get some work done.
  • Converted garages: If you have a detached garage that you would like to convert to an ADU, this is a great option because now your ADU has some bones to it. The structure can then be remodeled to fit a more comfortable life.
  • Backyard cottages: A small ADU can become anything you’d like. Some ADUs create a cottage feel that makes it appear not only homey but also cozy. These ADUs have stylish kitchens and living space, perfect for inlaws, or using it as a guest room.

What are the benefits of accessory dwelling units?
