Tips
- Window/door replacement without structural alteration still requires a permit in Riverton, but the permit itself carries no fee under Resolution No. 1355 — don't skip the paperwork just because it's free.
- The alteration fee schedule bundles equipment/material replacement categories (electrical service upgrade, mechanical equipment, plumbing alteration, water heater, gas piping test, water/sewer replacement) as flat per-item minimums rather than valuation percentages — see the electrical-permit, plumbing-permit, and mechanical-hvac-permit entries for those specific flat fees.
