Tips
- A straightforward furnace, AC, or water heater replacement qualifies for Hudson's One Stop (over-the-counter) permit track at a flat $125 fee, issued within 2 days — don't over-apply the longer Standard Building Permit process to a simple like-for-like replacement.
- New mechanical work bundled into a larger addition or new-construction project instead falls under the general valuation-based Building Permit Fee and 1-2 week review window.
