General Permit Tips

When do you typically need a permit?

Most cities require permits for structural work, including fences over a certain height, pools, ADUs, and sheds above a size threshold. Even projects that seem minor can trigger permit requirements, so it is always best to check first.

How to apply for a building permit

Visit your local building department or their website. Most jurisdictions accept online applications. You will typically need a site plan, project description, and may need contractor information. Processing times vary from same-day for simple projects to several weeks for larger builds.

Common permit violations to avoid

Building without a permit, exceeding approved dimensions, and ignoring setback requirements are the most common violations. Penalties can include fines, required removal of the structure, and complications when selling your home.
