Home Additions

A 20x20 addition, totaling 400 square feet, typically costs between $80,000 and $200,000 or more. The final price depends heavily on the room's complexity, foundation type, roofing, and interior finishes. For a basic shell with standard fixtures, you might expect costs on the lower end, while a fully finished space with custom cabinetry, premium flooring, and high-end systems will push the budget higher. Permits, engineering fees, and site preparation also add to the total.

At Royal Home Remodeling, we always advise getting a personalized quote based on your home's unique structure and your design goals.

The 30% rule is a financial guideline suggesting that you should not spend more than 30% of your home's current market value on renovations. For example, if your home is valued at $500,000, your total renovation budget should ideally stay under $150,000. This rule helps ensure you do not over-improve your property relative to the neighborhood, which can make it difficult to recoup your investment upon resale. At Royal Home Remodeling, we always advise clients to consider this benchmark when planning major projects, particularly for kitchens and bathrooms. While the 30% rule is a helpful starting point, factors like local market conditions in the San Fernando Valley and your long-term plans for the home also play a critical role in determining the right budget for your specific project.

For a 12x12 room addition, homeowners in the Van Nuys area can generally expect costs to range between $30,000 and $60,000. This price depends heavily on the scope of work, including foundation type, roofing, electrical, and HVAC integration. A simple shell addition will be on the lower end, while a fully finished space with premium materials and permits will reach the higher end. Labor and material costs in Los Angeles also influence the final number.

For homeowners in the Van Nuys area, adding an addition is typically cheaper than building a new house. A new custom home involves land acquisition, full foundation work, and complete utility hookups, which significantly raises costs. An addition, while still requiring permits and structural work, leverages your existing foundation and systems. However, the cost per square foot for an addition can sometimes be higher due to complex tie-ins. The best choice depends on your specific needs and property.
