Permitting Process: What to Expect in Your Community
The permitting process for an ADU can vary widely, often taking several weeks to months to finalize. Start by consulting with your local planning department to gather necessary documentation. Be prepared for potential delays due to changes in laws or policies relating to residential construction.
Understanding Zoning Laws Impacting Your ADU
Researching zoning laws in your area helps simplify the construction process. Understanding what is permissible can save you time and prevent expensive changes mid-project. For example, some areas have restrictions on unit size, type, or the ratio of the ADU to the primary structure.
