About Capital Construction

Capital Construction: ADU Builders Serving the Region

Capital Construction Inc. has built a strong reputation as an experienced ADU contractor in the region. Over many years, they have developed and refined their design, engineering, and construction processes to deliver accessory dwelling units that add both value and functionality to residential properties. Whether a homeowner comes in with a clear vision or needs guidance from the design team, Capital Construction works to respect the client's goals, budget, and timeline.

Their team offers a zero-obligation consultation to explore project ideas in detail before any commitments are made. This gives homeowners the opportunity to understand what is possible on their property and what the process involves.

Building Custom ADUs for a Range of Needs

Capital Construction works as a detached ADU builder and in-law suite builder, serving homeowners who want to house family members, create a granny flat, or add a rental unit to their property. Their familiarity with local ADU regulations means projects can move forward efficiently, with designs that meet local building and safety codes. This knowledge helps streamline the permitting process, which is often one of the more time-consuming aspects of ADU construction.

  1. In-law and granny suites
  2. Long-term rental units
  3. Short-term vacation rentals
  4. Home offices

What to Know About ADU Homes

ADU regulations vary by municipality, but there are two general requirements that apply broadly regardless of location:

  1. The new structure must be no larger than 1,200 square feet
  2. The property owner is required to live in one of the structures — either the main home or the ADU

Capital Construction's specialists walk clients through the specific requirements that apply in their area, helping to ensure the project is compliant from the start.

When working with Capital Construction as a licensed, bonded, and fully insured ADU builder, clients can expect:

  1. A streamlined permitting process
  2. Quality building materials from trusted brands
  3. Respect for the agreed budget and deadline
  4. Guaranteed workmanship

For homeowners considering adding a backyard cottage, Casita, or other type of accessory dwelling unit to their property, Capital Construction offers the experience and local knowledge to guide the project from initial consultation through to completion.

"Very easy to do business with. Quality work and very reasonable in terms of cost. We had them repair our front door frame and are very pleased with the work done. We will definitely call again as projects come up."

"I contacted Capital Construction for an estimate on a room addition. Nathan came out to give me an estimate, he was on time and explained the entire process. I decided to go with Nathan because everything was upfront, and I really liked how he answered all my questions and concerns. During the construction they were always on time and they worked very organized. They all did an amazing job on the room addition. I would use them again for any future projects."

"Capital Construction, Inc. is by far the best Company for all of your construction needs. We were referred to CCI by our pool contractor. We showed Nathan, the owner, a 3-D rendition of what we wanted and he had the plans drawn up, had the engineering taken care of, and dealt with the City of Murrieta Building Department through plan check, approval, inspections and final. The finish product is exactly what we wanted without exception. Nathan kept us informed every step of the way. If we had any questions or concerns, he answered them immediately. All of his employees are very professional and personable. We are very happy with the end result. We would highly recommend Nathan for any and all construction needs you may have. CCI built a glass block wall on the rear of our property, a full width covered balcony with glass railing, waterproof decking, lighting and fans. CCI also built a TV wall including a fireplace, lighting, fan, and alumawood cover for our sunken bar area. Nathan and his employees are truly professional and take great pride in their finish work product. 5 stars to Nathan and all of the employees that made our dream backyard a reality!"

"Beautiful ADU. Professional with great communication. We hired Capital Construction, and Nathan, to build an ADU in our backyard. We are thrilled with the results. Nathan walked us through the permitting process and was a professional communicator from beginning to end. Capital Construction had to over come numerous obstacles with weather and the city of Murrieta, and they handled it all in stride; all while providing amazing quality. This is exactly what you want in a general contractor and Id recommend them to anyone."

"Nathan did the most remarkable job of building my 2 bed apartment over the garage. It turned out even better than I has envisioned. He does quality work, even with COVID causing many delays and setbacks. He was always professional, honest, and focused on giving me all I asked for. He stayed within the estimate he had given and I couldn't be more happy with the results. I would definitely recommend Capital Construction for any of your construction needs."
