"We had a detached ADU built in our backyard in North Park and the whole process was smoother than we expected. The crew was respectful of our space, stayed on schedule, and the finished unit looks fantastic."
"Crimson Ridge remodeled our kitchen and two bathrooms, and the difference is night and day. They were upfront about costs from the start and there were no surprise charges at the end."

Yes, all ADUs in San Diego require building permits. California state law and the City of San Diego have specific rules about setbacks, size limits, and parking that apply to your project. We handle the full permitting process for you, including plan submissions and any required revisions.
It depends on the scope. A bathroom remodel might take 3 to 5 weeks, a kitchen 6 to 10 weeks, and a full ADU build 4 to 7 months including permitting. We give you a realistic timeline upfront and keep you updated throughout the project.
In most cases, yes. California's ADU laws have relaxed many of the old restrictions, and even smaller lots in neighborhoods like Hillcrest, North Park, and Normal Heights can qualify. We evaluate your specific lot during the initial consultation to confirm what's possible.
We handle design in-house for most projects, including ADUs and remodels. For larger or more complex builds, we work with local architects we trust. Either way, you won't need to coordinate between separate companies — we manage the entire process.
Generally, yes. Kitchen and bathroom remodels consistently rank among the top value-adding improvements, and ADUs can significantly boost property value while generating rental income. San Diego's strong rental market makes ADUs an especially smart investment for local homeowners.
