Who this is for

Built for the moment you stop Googling.

Homeowners

You're planning a deck, an addition, or a remodel. You want to know if you need a permit, what it costs, and what's involved — before you commit.

Real-estate investors

You're buying a property and need to know whether the work on record was permitted, what unpermitted work means for your ROI, and what disclosure law applies in the state.

Contractors

You need a fast sanity check on a city you've never worked in. Fees, review timelines, what the local inspectors actually look at first.

Agents & flippers

You're advising a client on renovation ROI or disclosing work at sale. You need source-cited facts and the right filing path.

What we are

We are not lawyers, contractors, or a permit expediter.

Our job is to give you accurate, source-cited facts so you can decide what to do next. Final authority on any permit question rests with your local building department.
