Services·Room Additions & ADUs
We've built more than extra square footage — we've built better solutions for families, income needs, and future plans. As a trusted ADU builder and room addition contractor in South Orange County, we manage everything from site planning and permitting to design, engineering, and construction — so you never have to worry about setbacks, soil reports, HOA approvals, or city inspections.
What We Build
ADUs and room additions —
what's the difference?
ADUs (Accessory Dwelling Units) are independent living units on your property — backyard cottages, pool houses, guest houses, garage conversions, or attached suites. They can be rented for income, used for family, or simply add significant resale value.
Detached ADU
A fully independent backyard cottage, guest house, or pool house with its own entrance, kitchen, and living space. The most flexible and highest-value ADU type for South OC properties.
Garage Conversion ADU
Transform an underused garage into a fully permitted, code-compliant living unit. One of the most cost-effective ways to add rental income or family housing to your existing property.
Attached ADU
An addition connected to your main home with a private entrance — ideal for multigenerational living or a rental suite that stays close but feels independent.
Junior ADU (JADU)
Up to 500 sq. ft. created within your home's existing footprint — a converted bedroom, attached garage, or interior space. Lower cost, faster permitting, same quality finish.
Why Homeowners Choose ADUs & Additions
More than square footage.
A smarter investment.
Multigenerational Living
Create a private space for aging parents or adult children while keeping everyone close under one property.
Rental Income Potential
Earn passive income with a fully equipped, code-compliant ADU. Most South OC cities allow long-term rentals of 30+ days.
Increased Property Value
Well-planned additions and ADUs significantly boost resale value in high-demand South Orange County neighborhoods.
Upgraded Lifestyle
A custom design tailored to your family's needs — whether it's a new master suite, studio, or guest unit.
Work & Creativity Space
Build a quiet, dedicated area for remote work, fitness, or hobbies — without leaving home.
