About ADU Gurus

About ADU Gurus™ — California's ADU Builder Specialists

ADU Gurus™ is a California-based accessory dwelling unit builder established in 2020 in response to the state's growing housing demand. With over 25 years of experience in residential real estate, land use oversight on city planning commissions, and deep expertise in ADU construction on both single-family and multi-family lots, they bring a comprehensive, streamlined solution to homeowners and investors seeking quality housing options on their own property.

Their mission is to empower California homeowners to craft personalized ADUs that cater to their families while delivering long-term financial rewards — all while positively impacting local communities. From concept to keys, ADU Gurus™ is committed to exceptional service and innovative designs tailored to each client's individual needs.

ADU Design Plans and Engineering Services

As a full-service ADU contractor, ADU Gurus™ handles the technical complexities of ADU development so homeowners don't have to. MEP engineering — covering mechanical, electrical, and plumbing systems — forms the backbone of every build. They prepare all permit-ready plans, including MEP plans and Title 24 documents, which address the environmental and energy compliance requirements under California's Building Standards Code.

Whether a client is working from a custom design or utilizing pre-approved city plans, ADU Gurus™ manages the entire planning and permitting process. Their design services include:

  1. Floor Plans — Efficient layouts featuring open floor plans, compact kitchens, and multifunctional living areas
  2. Structural Plans — Permit-ready documentation submitted directly to the city's Building Department
  3. Title 24 Compliance — Full preparation of required energy and environmental documentation

As a trusted garage conversion contractor and JADU contractor, they work with both attached and single garage conversions as well as larger detached ADU builds up to 1,200 square feet. Their team draws out floor plans and manages logistics to ensure the space is arranged optimally for the homeowner's needs.

For ADUs under 750 square feet, ADU Gurus™ helps clients take advantage of California's waived Impact Fees — a significant cost saving that has been in effect since January 1, 2020. Impact fees are often among the most expensive charges a city imposes during the ADU building process.

What Is an Accessory Dwelling Unit?

An accessory dwelling unit is a secondary housing unit located on the same property as a primary residence. Also known as granny flats, in-law suites, casitas, companion units, or backyard cottages, ADUs have grown in popularity across California due to their versatility and financial benefits. They can take the form of detached structures, home additions, or conversions of existing spaces such as garages or basements.

California's ADU-friendly legislation — beginning with SB1069 in 2017 and further expanded through subsequent Senate Bills including SB9 in 2022 — has made it easier than ever for property owners to build ADUs on single-family lots. These laws have reduced fees, streamlined permitting, and increased the number of allowable ADUs per property.

The key benefits of building an ADU include:

  1. Increased property value
  2. Rental income potential
  3. Multigenerational living options
  4. Design flexibility

ADU Gurus™ also offers financing connections through partnered professionals, as well as property valuation analysis through their licensed California Real Estate Broker on staff — helping clients understand the value of their property both before and after ADU construction. If a client does not yet own an ADU-ready property, they can assist in finding one.

"I am a real estate broker and ADUs are another beast all together. Lisa is amazing. I had a question about if a listing of mine could have an ADU and she quickly gave me so much information! She is a wealth of knowledge that I refer people too all the time. She is friendly, responsive and knows her stuff! I cannot recommend her enough to people."

"After being scammed for over two years by another ADU company and reeling from the deceit, timemoney lost, Lisa from ADU Gurus swooped in to rescue us when all hope of building my mother her retirement home seemed to be lost. Her vast knowledge of the industry, professionalism, honesty, dedication and kind heart have been such a breath of fresh air. If you considering building an ADU or are feeling lost with your current ADU project, I cant imagine there is anyone else who will help you reach your goals better than Lisa!"

"I started my ADU journey with someone else. I was telling a friend how confusing all this was and I wasnt getting any guidance from the person I was using. My friend told me about ADU Gurus and to call them. I did and explained to Lisa I was already using someone else and understood if you couldnt help. Lisa sat on the phone for over half hour explaining everything to me and putting my mind at ease about planning and executing an ADU. I was so impressed with her I let the person I was working with go and immediately hired ADU Gurus. From start to finish everything was explained to me and I was guided through each step of the way. The builders ADU Gurus use were great. They were professional and understanding of all the questions I had. I highly recommend ADU Gurus to anyone thinking about building. Shawn Fernandes"
