Cedar Park is one of the fastest-growing communities in the Leander corridor, and MLD Services has served it since 2009. If you're replacing an aging system, you've probably wondered whether you need a permit. Usually you do — and the simplest path is to hire a licensed contractor who takes care of it as part of the job. Here's the Cedar Park specifics.

When you need a permit in Cedar Park

  • AC, furnace, air handler, or full-system changeout — typically yes.
  • New installs and additions — yes.
  • Major ductwork or line-set work — often yes.
  • Routine repairs, tune-ups, filter or capacitor swaps — typically no.

Who issues the permit

Inside the city limits, the City of Cedar Park building inspections department is the Authority Having Jurisdiction. A wrinkle worth knowing: Cedar Park straddles both Williamson and Travis counties, so for parcels outside the city limits the county may be the AHJ. We confirm the correct jurisdiction and current fee for your address before starting.

Why the permit protects you

  • Code + safety: independent inspection of the electrical, gas, and mechanical work.
  • Warranty: manufacturers can deny claims on unpermitted installs.
  • Resale: unpermitted work can stall a sale.
  • Accountability: the job is tied to a licensed contractor.

If a bid is cheap because it skips the permit, it isn't really cheaper — see what an honest quote includes.
