Isaman design, Inc.
ADU Contractors in San Luis Obispo
Average rating: 5 out of 5 starsApril 13, 2012
“Isaman design is a professional organization that completes their designs on an individual basis. They got to know us, and our specific wants and needs , then created the house design based on that. They also offered exceptionally talented advice ,which made the whole process of designing our own home manageable and fun! The outcome was everything and more than we had hoped for. And the Isaman design team was there, guiding us every step of the way, from our design dreams to a finished beautiful home! ”

Jessica Lehrbaum Architect
ADU Contractors in San Luis Obispo
Average rating: 5 out of 5 starsJuly 16, 2017
“We had no idea how wonderful it could be to have an architect's help until we met Jessica. We felt listened to and like she really took the time to hear an understand our project. When we called Jessica (at the suggestion of our realtor) for help in remodeling the kitchen in the house we were purchasing, we had no idea what a gift she would be! Not only is she excellent with all the design details and measurements and everything else an architect is supposed to do, but she was able to help us with materials and think outside the box to accomplish our goals in creative ways. Jessica also helped us tie in the look and feel of our kitchen/dining room to our front outdoor space and thought of other details we wouldn't have even considered. Jessica was professional and easy to work with, she was gracious and even able to understand/communicate well with both my husband and me and help us figure out what we wanted. We are so thankful we found such a great Architect in SLO!!”
RF Building Corporation
ADU Contractors in San Luis Obispo
Average rating: 5 out of 5 starsFebruary 14, 2024
“When I was doing a gut remodel on my home there was no question on who I was going to use. Stephen and his team responded quickly and thoughtfully walked me through the process. They were honest and set clear exceptions for cost and timelines (which they correctly estimated from the beginning). The work was done beautifully and they were always considerate to clean up after each day. I could not recommend them enough and look forward to working with them again on my next project.”
Ferreira Inc
ADU Contractors in San Luis Obispo
Average rating: 5 out of 5 starsAugust 22, 2013
“I hired Dan to coordinate my recent kitchen remodel. I had a good idea what I wanted but several other people I sought bids from discouraged me and tried to change my plan. This company had a 'can do' attitude and nothing was too hard for them to carry out. My kitchen remodel knocked out a small wall, moved the sink (which involved extensive plumbing), stove and refrigerator placement, installed new cabinets, counter tops, flooring,windows,appliances,lighting and a barn door. All of the building professionals employed for this job were respectful, reliable, and well qualified to carry out the job at hand. It was a pleasure doing business with Ferreira Inc. The project lasted 2 months from planning to completion and was completed within the planned budget amounts. We received good value for quality work.”
Nathan Simpson Architect
ADU Contractors in San Luis Obispo
Average rating: 5 out of 5 starsApril 3, 2023
“We purchased and older home in Sonoma Valley a few years ago and immediately turned to Nathan for his creativity, thoughtful design, and collaborative work style. We had to quickly get the house in shape for move-in and Nathan LISTENED to what we wanted short term and what our potential vision was for the longer term. He then provided the design changes and permit/construction drawings we needed. Now, a few years later, we are ready to bring the long-term vision to life and Nathan is at the helm of that effort, guiding us through the design options with his amazing taste, talent, and experience. I recommend Nathan Simpson for any architectural needs, but specifically for residential.”
Legacy Builders & Design Inc.
ADU Contractors in San Luis Obispo
Average rating: 5 out of 5 starsFebruary 5, 2023
“Simply put, Legacy Builders were amazing to work with from start to finish. Communication is top notch, everyone we worked with (Jon, Sadie, Evan and Steven) were easy to get ahold of and were quick to respond. Jon and Sadie took the time up front to help us design our ADU and the final product reflected that, even going over potential hiccups that could happen so we would be aware and prepared if anything did happen. Their estimates of work, and project management skills are top notch offering different options for estimates depending on which kind of work/look we wanted. They’re super flexible and work with you to get things just the way you like for as close to your budget as is possible. Evan (our project manager) would always keep us in the loop about when things were happening and next steps to come, so we were never left wondering "what's happening next?". They’re loyal to their people, and their people are loyal to them. Hands down would recommend to anyone needing construction/design work done. If we have another project in the future we will definitely be returning costumes.. oh yeah and our project ended up being completed a whole 2 MONTHS than the original estimated completion date! We absolutely LOVE our ADU- now 840sqft which my husband and I live in and couldn’t have done it without Legacy Builders.”
STUDIO PRIME ARCHITECTURE (SP-ARC)
ADU Contractors in San Luis Obispo
Average rating: 5 out of 5 starsMay 9, 2018
“Currently engaged with Studio Prime in support of a design/build project here in the city of San Luis Obispo. I couldn't ask for a more knowledgeable and professional group to work with, but importantly, they also have a sense of humor (especially John). They are helping my wife and I design (and eventually build) a 3,000 sf custom home on an, um, "interesting" hilly site that is presenting some challenges. However, these guys know their stuff, and are deftly navigating us around those challenges. Strongly recommend these guys!”

An accessory dwelling unit (ADU) is a separate living space that can be added to your property. It functions as an additional dwelling on the same land where your main home is located. ADUs have their own amenities and entrance, providing a self-contained living area. Unlike a traditional home, an ADU cannot be sold separately and is considered part of the same property.

ADUs are subject to specific zoning regulations and building codes in San Luis Obispo. These regulations determine where and how an ADU can be constructed, ensuring compliance with local laws and requirements. It’s important to consult with local authorities or a professional contractor who is familiar with ADU regulations in your area to understand the specific legal differences and ensure your ADU meets all necessary criteria.

Consider these options for cost-effective ADU:
  1. Prefabricated ADUs: Affordable and easy to assemble, they’re a practical choice. Many prefab ADUs cost under $100,000.
  2. Traditional Construction: Work with an ADU contractor to find budget-friendly options and make smart choices.
Tips for cost-effective ADU construction:
  1. Define your needs: Determine the purpose of your ADU, whether it’s for family, rental income, or a home office.
  2. Consult a contractor in San Luis Obispo: Their expertise can help with cost-effective materials, designs, and planning.
  3. Prefabricated components: Consider using prefabricated elements like cabinets or bathroom fixtures to save time and money.
  4. Explore financing options: Look for ADU-specific loans or programs to help cover costs.
Ensure compliance with local regulations and seek professional advice. A knowledgeable contractor can make the process smoother and cost-effective.
