Types Of Home Additions We Can Build

Bump-out addition: This is a small-scale addition that extends an existing room by a few feet, typically to create more space or add a specific feature like a window seat or storage area.

Room addition: This involves adding a new room or rooms to the existing structure, such as a bedroom, bathroom, or family room. Room additions can be built on any level of the home, including the basement or attic.

Sunroom or four-season room: These are glass-enclosed spaces designed to provide natural light and additional living space while allowing homeowners to enjoy the outdoors year-round.

Second-story addition: This type of addition involves adding an entire new level to a one-story home or extending the living space of a two-story home. This can significantly increase the square footage of the home and may include new bedrooms, bathrooms, or living areas.

Garage conversion: This involves converting an existing garage into living space, such as a bedroom, office, or family room. This type of addition is popular for adding square footage without altering the home's exterior appearance.

In-law suite or accessory dwelling unit (ADU): This is a separate living space within the main home or a detached structure on the property, designed to accommodate extended family members or renters. In-law suites typically include a bedroom, bathroom, kitchen, and living area.

Basement conversion: Transforming an unfinished or underutilized basement into a functional living space, such as a home theater, playroom, or additional bedroom and bathroom.

Dormer addition: This involves adding a dormer window to an existing sloped roof, creating additional living space and headroom in an attic or upper-level room.

Yes, you will need a building permit for most home additions in Calabasas. Whether you're adding a new room, expanding your kitchen, or building a second story or ADU, the City of Calabasas requires permits to ensure the work meets local building codes and zoning regulations. At All Exclusive Construction, we handle the permitting process for you—including plan submissions, coordination with city officials, and ensuring full code compliance—so your project stays on track and stress-free.

Zoning regulations govern various aspects of construction, including setbacks, building heights, and land use.  These can vary from property to property.  At All Exclusive Construction we will be able to discuss the specific zoning issues that might affect your home addition project.

The timeline for a home addition depends on factors such as the size and complexity of the project, weather conditions, and our current availability. We can discuss a realistic timeline with you for your particular addition project.  A home addition is generally a several week, if not a few months, long project.

Property taxes in Santa Clarita are based on the assessed value of your property. A home addition may increase your property's value and, consequently, your property taxes. You would need to contact the Santa Clarita Revenue Department to discuss how your addition might impact your property taxes.

Financing options for home additions may include personal savings, home equity loans, home equity lines of credit (HELOC), cash-out refinancing, or personal loans. Consult with your financial advisor, bank, or mortgage specialist to determine the best option for your situation.

A home addition will increase the value of your property, which may require updating your homeowner's insurance coverage. You will need to contact your insurance agent to discuss any changes needed to ensure you and your new home addition and it's contents are adequately covered.

Depending on the scope and complexity of your home addition project, it may be possible to continue living in your home during construction. However, you should be prepared for disruptions such as noise, dust, and limited access to certain areas of your home. We can discuss the construction schedule and potential disruptions with you before work begins.

Depending on the complexity of your home addition, you may need to consult with an architect or designer to create detailed plans and ensure your project meets local building codes and regulations. A professional designer can also help you maximize space, create a cohesive design, and ensure the addition complements your existing home.

At All Exclusive Construction we work closely with several local architects and designers based in Santa Clarita, CA and can recommend someone if this is required.

Incorporating energy-efficient features in your home addition can reduce energy consumption and save on utility costs. Consider options such as energy-efficient windows and doors, insulation, heating and cooling systems, appliances, lighting, and solar panels.  We can discuss green, energy-efficient options with you.
