Frequently Asked Questions

Get answers to common questions about our room additions & extensions.

How long does a room addition take in West Covina?

Room additions typically take 6-12 weeks depending on size, complexity, and permit approval time. Single-room additions may take 6-8 weeks, while multi-room or second-story additions can take 10-16 weeks. We provide detailed timelines during the planning phase and keep you updated throughout construction.

Do I need permits for a room addition in West Covina?

Yes, room additions require building permits from the West Covina building department. We handle all permit applications, architectural drawings, structural engineering, and inspections to ensure your addition meets all local building codes, zoning requirements, and safety regulations.

Will the addition match my existing home's architecture?

Absolutely. We specialize in seamless architectural integration, carefully matching rooflines, siding materials, window styles, exterior finishes, and design details to ensure your addition looks like it was part of your original home design. Our goal is invisible integration.

How much does a room addition cost in West Covina?

Room addition costs vary based on size, complexity, and finishes. Basic single-room additions start around $40,000-60,000, while luxury additions with bathrooms or kitchens can range from $80,000-150,000+. Second-story additions typically cost more due to structural requirements. We provide detailed estimates based on your specific needs.

Can I add a second story to my existing home?

In many cases, yes, but it depends on your home's structural capacity and local zoning requirements. We conduct thorough structural evaluations and work with engineers to determine feasibility. Second-story additions require additional foundation reinforcement and structural modifications but can maximize your lot's potential.

Will a room addition affect my home's resale value?

Quality room additions typically increase home value by 50-80% of the construction cost, depending on the type of addition and local market conditions. Bedroom and bathroom additions generally provide the best return on investment, while functional spaces like home offices also add significant value.

How do you handle utilities and HVAC for the new space?

We extend your existing electrical, plumbing, and HVAC systems to serve the new space, ensuring proper load calculations and code compliance. This may require electrical panel upgrades or HVAC system modifications to maintain efficiency and comfort throughout your home.

Can I live in my home during room addition construction?

Yes, in most cases you can remain in your home during construction. We take measures to minimize dust, noise, and disruption, and we can often maintain separate access to the construction area. We'll discuss specific arrangements during planning to ensure your comfort and safety.

What's the difference between a room addition and a home extension?

Room additions typically add individual rooms, while home extensions can include multiple rooms or entire wings. Extensions often involve more complex structural work and may include multiple systems. Both require permits and professional construction, but extensions generally take longer and cost more.

Do you handle landscaping restoration after construction?

Yes, we include site cleanup and basic landscaping restoration in our room addition projects. This includes grading, seeding or sodding disturbed areas, and restoring walkways. We can also coordinate with landscaping professionals for more extensive restoration or enhancement work.
