FAQ — ADU Legalization Citrus Heights
What does “ADU legalization” mean?
ADU legalization is the process of taking an existing ADU that was built without permits and bringing it into compliance through plans, permits, inspections, and required construction corrections. The goal is a safe, code-compliant unit that can be legally used.
Does my ADU qualify for an amnesty-style legalization program?
Some cities offer amnesty programs for certain older ADUs. Eligibility commonly depends on when the unit was built and its existing conditions. The first step is usually an as-built evaluation, then confirming the local process and requirements.
Do I have to fix health and safety issues right away?
If an inspection identifies life-safety or health-safety hazards, those items typically need to be corrected promptly before moving forward with other improvements. We help you prioritize the work and build a realistic scope.
Can I delay some non-life-safety corrections?
In some cases, there may be options to complete certain non-life-safety items over time. The availability of any delay process depends on local rules and the type of corrections identified. We can explain practical options once the unit is evaluated.
