"I would recommend Reliance to anyone looking to upgrade their home. Everything went exactly how it was explained from beginning to end, and on top of that, they were so clean and fast that we barely knew they were here."
Detached and attached units, garage and interior conversions, and junior ADUs across Southern California. Licensed, in-house crews. No subcontracting, no hard sell, just an honest plan for your property.


























An accessory dwelling unit is one of the smartest investments a Southern California homeowner can make. Here's what a properly permitted ADU can do for your property.
A legal, independent living space you can rent long term. Many of our clients build ADUs specifically to add a steady monthly income stream to their property.
A private space for aging parents, adult kids or long-term guests. Everyone stays close without giving up independence, comfort or privacy.
Added square footage and a second livable unit raise what your property is worth. An ADU keeps paying you back, whether you rent it, use it or sell.
We visit your property, listen to your goals and give you an honest, itemized estimate. No obligation.
Our in-house team draws the plans and engineers the unit to fit your lot, your budget and city requirements.
We handle all the city paperwork and approvals ourselves, so you never have to chase a permit office.
Our own licensed crews build your ADU start to finish, then hand you the keys after the final walkthrough.
Forty percent of our business comes from repeat and referred customers who already know our work can be trusted.
Planning, design, engineering, permits and construction, all under one roof. You deal with one team the whole way through.
Our own trained crews handle your project from the first inspection to the final walkthrough. We never subcontract a job we can do ourselves.
