Our Process

You bring the vision, we walk you through every step.

Walk Through Every Step
Design & Planning 02

Design & Planning

Once you decide you're ready to see what's feasible on your property, our project consultants will work with you in two to three phases, depending on your build type. Phase 1 begins our site study, project scope, preliminary designs, and price estimations for your project. Phase 2 begins the creation of your architectural plans and additional city construction documents. If you choose to build with us, signing a Construction Agreement allows us to submit your documents to the city for a building permit. In the meantime, you'll work with our interior designer to finalize selections before the build starts.

At our first meeting, we’ll do a walk-through of the spaces you want to remodel and discuss your ideas, lifestyle, budget, and timeline to determine the scope of work. At this point, we’ll be able to tell you what the approximate cost and duration will be based on projects we’ve done that are similar to yours.

Real homes. Real stories.

We had a great experience working with Valley Home Builders for our ADU. There's some inherent challenges with construction of this scope (especially when it comes to permits), and our project was no exception, but I felt that the process was made very transparent to us, especially by Yazan at VHB, and in the end we are very happy with the final product. I would recommend them to anyone looking to build an ADU.

We had an absolutely amazing experience working with Yazan and Natalie on our ADU project! From start to finish, their professionalism, attention to detail, and commitment to excellence truly stood out. The project was completed right on time, which is a rare and much-appreciated achievement in the construction world. Their follow-through was exceptional—any questions or concerns we had were promptly addressed, and they kept us informed every step of the way. The quality of their work exceeded our expectations. Every detail was executed with precision, and the finished ADU looks stunning. It's clear that they take immense pride in their craftsmanship and customer satisfaction. We couldn’t be happier with the result and highly recommend VHB to anyone looking for a reliable and talented home builder. Thank you for making our vision a reality!

We are almost done with a large addition and remodel with Valley Home Builders, and it's been a great experience in both the design and build phases. We worked to come up with a great floorplan that met our budget, and the construction has gone smoothly, quickly and on schedule- we are anticipating moving in before our estimated completion date!

Real homes. Real stories.

We recently built an ADU with Valley Home Builders and would definitely work with them again. From the beginning, the operation manager Yazan had always been transparent about pricing, respected our budget and kept us on track. The architect Natalie was so nice to work with; she considered our needs and got us through the permitting process with no comments regarding the architectural design. The project manager Alex was also amazing. The whole Valley team: their building works were beautiful! Like any big construction project, there’re some small hiccups along the way but Valley always tried their best to resolve and meet our expectations. All in all, we’re very happy!

Before You Build

Here’s what most people want to know.

View All FAQs

The first step is to schedule a free initial consultation. We’ll do a walk-through and discuss your ideas, lifestyle, budget, and timeline to determine the scope of work. While we can’t give you an estimate without design plans, we can tell you if your budget is realistic. If money is tight, there are ways to economize. Many projects can be divided into phases or reduced in scope. Rather than adding a new master bedroom suite, it may be more cost-effective to remodel an existing bath. Finishes matter too. A ceramic tile backsplash can be as attractive as a glass mosaic. A standard tub can be substituted for a jetted spa. Domestic hardwood is an economical alternative to exotic wood flooring. If you choose to move forward to the Preliminary Design phase, we’ll give you choices that fit your budget without compromising quality or style

Planning and communication are key. We start with detailed scopes, clear allowances, and realistic timelines so expectations are aligned before construction begins. Throughout the project, you’ll receive regular updates, milestone check-ins, and transparent change-order approvals to keep both budget and schedule under control.

Yes. Valley Home Builders is fully licensed, bonded, and insured for residential remodeling work in California. We can provide proof of licensing and coverage before work starts, and we maintain strict safety and compliance standards throughout every phase of construction.

There are many ways to refresh your space without a full gut remodel. We can prioritize high-impact upgrades like tile, vanity, lighting, and fixtures while preserving existing plumbing locations. That phased approach helps you modernize the room now and plan larger improvements later.

Absolutely. Our design-build process focuses on making additions feel seamless, not bolted on. We evaluate rooflines, proportions, exterior finishes, and interior circulation to ensure the expanded home feels cohesive and true to your preferred architectural style.
