Looking to expand your living space in beautiful Belmont, CA? Whether you’re adding a new bedroom, remodeling your kitchen, or building upward with a second story, Royalty Builders brings expertise, creativity, and craftsmanship to every home addition project. We help Belmont homeowners maximize space, comfort, and home value—all while staying in the neighborhood they love.

Custom Kitchen Additions in Belmont

The kitchen is often considered the heart of the home—a place where meals are prepared, and memories are made. If your current kitchen lacks space, modern amenities, or the layout you desire, a custom kitchen addition can transform it into a culinary haven. Imagine incorporating a spacious island for family gatherings, state-of-the-art appliances for gourmet cooking, and ample storage to keep everything organized. Our team works closely with you to design a kitchen that reflects your lifestyle and meets your culinary needs.

Stylish Bathroom Additions in Belmont

An additional bathroom can significantly enhance the comfort and convenience of your home, especially for growing families or frequent guests. Beyond functionality, a well-designed bathroom serves as a personal retreat—a space to relax and rejuvenate. Whether you’re envisioning a spa-like master bath with a soaking tub and rainfall shower or a compact yet elegant powder room, we ensure that every detail, from lighting to fixtures, aligns with your vision and complements your home’s design.​

Sunroom Additions in Belmont

A sunroom offers a unique blend of indoor comfort and outdoor ambiance, allowing you to enjoy Belmont’s natural beauty year-round. These versatile spaces can serve multiple purposes: a serene spot for morning coffee, a vibrant area for indoor plants, or an inviting space for entertaining friends and family. Designed with expansive windows and thoughtful insulation, our sunrooms provide panoramic views and abundant natural light while maintaining energy efficiency and comfort in all seasons.

Functional Room Additions in Belmont

As lifestyles evolve, so do the needs for additional functional spaces within the home. Whether you require a dedicated home office to enhance productivity, a playroom to keep the kids engaged, or a guest suite to accommodate visitors, we tailor each room addition to your specific requirements. Our designs seamlessly integrate with your existing floor plan, ensuring that the new space feels like a natural extension of your home, both in flow and aesthetics.

Second Story Additions in Belmont

When lot space is limited, building upward with a second-story addition can effectively double your living area without sacrificing outdoor space. This approach is ideal for adding multiple bedrooms, additional bathrooms, or even creating a separate living area for extended family. Our team carefully evaluates the structural integrity of your existing home, designs a second story that harmonizes with the original architecture, and manages all aspects of construction to deliver a cohesive and functional expansion.

Home Addition Costs in Belmont

One of the most common questions we get is: “How much will a home addition cost?” While pricing can vary based on the size, design complexity, materials, and permitting requirements, here’s a general breakdown to help you plan.

Interior Additions

Interior additions typically involve expanding or reconfiguring space within your home’s existing footprint—or adding new rooms attached to the main structure.

✅ Room Additions (Bedrooms, Offices, Family Rooms): $300–$450 per square foot
✅ Kitchen Expansions: $350–$500 per square foot
✅ Bathroom Additions: $350–$600 per square foot
✅ Second-Story Additions: Starting at $400 per square foot and up

Interior additions often require plumbing, electrical, HVAC modifications, and structural work, all of which can impact cost.

Exterior Additions

Exterior additions expand your home’s footprint outward or upward and often include site preparation, foundations, and roofing work.

✅ Garage Conversions or Expansions: $250–$400 per square foot
✅ Sunroom Additions: $300–$450 per square foot
✅ Covered Patios & Outdoor Living Rooms: $200–$350 per square foot
✅ Accessory Dwelling Units (ADUs): $400–$700 per square foot, depending on size and whether it’s attached or detached

Exterior work can sometimes involve additional permits or compliance with Belmont’s setback, height, and floor area ratio (FAR) requirements—which we handle entirely on your behalf.

Frequently Asked Questions – Home Additions in Belmont

How long does a home addition project take in Belmont?
Most additions take between 3 to 6 months, depending on the project’s size and complexity. Permitting, design, and construction are all factored into the timeline.

Do I need a permit for a home addition in Belmont?
Yes. The City of Belmont requires permits for most structural changes, including room additions, garage conversions, and ADUs. We manage the entire permitting process for you.

Can you match the design of my existing home?
Absolutely. Our additions are designed to blend in seamlessly with your current structure—rooflines, siding, windows, and materials all matched for a natural look.

Are there zoning restrictions in Belmont I should be aware of?
Yes. Belmont enforces setback requirements, height limits, floor area ratio (FAR), and other zoning rules. We handle all compliance checks during the planning phase.
