Frequently Asked Questions
How long does an ADU take to permit and build?
Typical projects range from 6–12 months. Permitting times vary by city; pre-submittal meetings often shorten review times.
Can I rent my ADU?
Most jurisdictions allow rental; some have occupancy conditions. We’ll review local rules during feasibility.
What affects cost the most?
Site conditions, foundation type, utility distance, and finish level are primary cost drivers. Expect contingency for unknowns like underground utilities.
What if code changes mid-project?
We monitor local updates. If a code change affects your approved plans, we’ll outline options and costs before proceeding — and minimize delays where possible.
