Lyon County, not Washoe
Dayton is about 12 miles east of Carson City at 4,397 ft, and it is the second-oldest settlement in Nevada. Building permits come from the Lyon County Community Development Building Department. Washoe County's like-for-like window exemption and the City of Reno's EZ Permit sheet do not govern here.
We could not find a published Lyon County rule on same-size window replacement, so ask the installer or the department whether your job needs a permit. Ask who pulls it, and get that in the written quote.
The Aspen Creek building pause, read carefully
Lyon County paused will-serves, final maps and building permits in Dayton for developments that add sewer flow, because of design flaws in the Aspen Creek rapid infiltration basin. The notice describes new sewer-adding development. A window swap adds no sewer flow and is a different kind of job, but the county's status can change, so check with Lyon County Building before assuming either way.
- Ask whether the pause currently touches any permit your project needs.
- If you are adding rooms or a new bath alongside the windows, ask separately about those pieces.
- Keep any county correspondence with your contract.
Growth since the 1990s
Dayton grew from 8,964 people in 2010 to 15,153 in 2020, up 69%, with most residential growth on the east side of the Carson River since the 1990s. That makes houses mostly 30 years old or newer, where the usual issues are failed insulating-glass seals, worn weatherstripping and builder-grade vinyl or aluminum windows past their service life.
| Frame | Typical lifespan (This Old House) | Page |
|---|---|---|
| Vinyl | 20 to 40 years | vinyl windows |
| Aluminum | 15 to 30 years | window frame materials |
| Fiberglass | 30 to 50+ years | fiberglass windows |
We have not confirmed Dayton's local wind or distance-to-Reno figures, so we do not make claims about either.
Repair, glass swap or replace
A foggy pane on a sound frame may only need new glass, and a national guide puts glass replacement at $300 to $880 (Fixr), with double-pane glass at $150 to $600. A frame that is cracked or no longer seals is a replacement candidate, and the retrofit vs. full-frame page explains the two methods. Window repair lists what can be fixed without replacing the unit.
Costs in the Dayton area vary and are not published by any guide. The federal 25C credit ended for property placed in service after December 31, 2025.
