I hired West Coast for a concrete slab for a patio. He gave me a quote and started the job within a week. We are happy with the work and it looks great! Everyone who was on our property was respectful and cleaned up after the job was complete. They were very reasonable and professional.

So happy to have our contractor, Rene Rivera, bring our beautiful Granny Flat to life. It is spectacular!

Rene took charge of building an ADU above my garage, and I couldn’t be happier with the result. The quality of his work is top-notch, and it’s clear he takes real pride in what he does. Plus, his pricing was fair and upfront, which I really appreciated. Looking back, my only regret is not getting Rene involved in the design process too.

Today I had an amazing talk with Rene at West Coast Building and Design. He was quite informative and gave me some great ideas and help in our situation. I highly recommend this place.

Great contractor to work with! Rene built a terrific house for me. It sold in less than 24 hours for 50k above asking price. He is not just a skilled builder but a really nice guy. He also contracts for a fixed price which includes an in house architect and interior decorator

Best customer service. West Coast was very professional and efficient, on my remodel, definitely recommend them to friends and family.

I worked with Rene on an ADU in La Mesa in 2023. He was on top of all subs, quick to respond, and managed the project like a pro. The ADU turned out great, and we couldn’t be happier with the experience!

I hired Rene to build a 1200sf ADU w/ a 2 car garage. One thing I really liked about Rene is that he is a man of his word. What I really appreciate was his responsiveness to all my communications; even during some very tough situations, he picked up the phone. I am very satisfied with end result.

Very much appreciated working with Rene! He was very communicative and, with the exception of delayed products due to supply chain, his timelines were realistic and spot on. We are thrilled to have our ADU completed by West Coast Building and Design. We would definitely work with him again!

Rene at West Coast has got to be one of the most reliable, honest, professional and overall a well put together contractor that I have dealt with in the industry. I have nothing but good to say about him and his company. His work ethic and professionalism are always tip top.

Rene and his team built our 750 sq ft ADU. They took care of all permits, design, plans, and construction. Our project was quite complex including over 150 ft of trenching operations surrounding our entire main house and navigating the large number of state and local regulations regarding the upgrade of our electrical panel. Rene always displayed the highest level of integrity throughout the project and in the end it came out much better than we thought it would.

Very professional and quick. The workers get things done either on time or ahead of schedule and always answered any questions I had. They are friendly, fast, and affordable. Whenever someone tells me they want work done, I recommend them.

Rene Rivera for west coast building and design built a ADU (granny flat, Casita, mother-inlaw suite) in my back yard. He went above and beyond during the height of covid to complete this project. Everything went smooth and fast.

Built and ADU for my mother-in-law… she now lives like a queen.

If you’re looking for a great value and great costumer service! This is the right company for you! They just finished building our 2 bedroom 2 bath Granny flat. Good communication with Rene, always a phone call away.

My husband and I hired Rene’ and his team to get our ADU off the ground. This was NOT a small project. It is really a 1,200 sq’ custom home with a 2-car garage that just happens to be on our property. Rene was with us from the start, offering suggestions and working with us in every way. There was a work-ethic and caring attitude across the board. His team was extremely helpful in making our dream a reality.

He blew us out of the water with his knowledge, timeliness, and of course having a quote within our budget. We could not have been happier with the work Rene and his team completed. Rene was there through the whole process of bringing our vision to life. Whether it was finding ways for us to save money or time managing his team, they got it done.

Rene’s team did our granny flat and did an amazing job. Rene was awesome to work with and gave me the best bid. I’ll be using them for my eventual remodel!

Great guys and great work! Needed my front and back porches, along with some pretty major repairs done to my roof from a bad leak. Called around and these guys gave me a really good quote and could start work ASAP. Finished on time and looks like new!
