First: which counter your address answers to
There is no single Reno-area building department. Three separate authorities review residential work across the valley, and which one reviews yours is a function of the parcel, not of the mailing address on your utility bill.
- City of Reno: addresses inside Reno city limits.
- City of Sparks: addresses inside Sparks city limits.
- Washoe County: unincorporated addresses, which includes plenty of parcels carrying a Reno or Sparks mailing address.
Each runs its own submittal requirements, fee schedule, correction process and inspection scheduling. A neighbour’s experience two streets away is not evidence about yours if the boundary runs between you, and the most common early mistake is building a schedule around the wrong department. Our service-area pages name the reviewing authority for each city we hold contracts in.
It does not quote a fee, a code section or a setback, the distance a structure has to keep from the property line, and it quotes a review time only where a department has published one. Those are published by each jurisdiction and they change; a number repeated from memory on a contractor’s blog is exactly the kind of thing that gets planned around and turns out to be two years old. Where a jurisdiction-specific figure belongs, this page quotes it from the department’s own page with the date we read it, or says plainly that the department publishes none.
What “the permit timeline” is actually made of
People talk about permit time as if it were one number the counter hands out. It is a chain of five things, only one of which is the review itself. The ones that most often eat the calendar are on the applicant’s side of the desk.
- Preparing the set. Drawing, coordinating and assembling everything the application requires. Entirely within the project’s control, and where an experienced submitter saves the most time.
- Intake and completeness. The department confirms the application is complete enough to review. An incomplete package can be rejected here without ever reaching a reviewer, which feels like nothing happening.
- Plan review. The technical review: building and structural always, and mechanical, electrical, plumbing, energy, fire, planning and public works depending on the scope, meaning how much of the house the job actually touches. Several can run in parallel; the file moves at the pace of the slowest.
- Corrections and resubmittal. Comments come back, the design team answers them, the set goes back in. This is a loop, not a step, and every pass costs the response time plus a re-review.
- Issuance. Fees paid, permit issued, approved set stamped and returned. Work can start, and inspections are scheduled against that set.
Written that way, the reason two identical-looking projects finish permitting months apart stops being mysterious. One went around step four once. The other went around it three times.
What each department publishes about review time
The figure people search for is a first-review target: how long a department aims to take over its first pass through a complete set. On 24 September 2026 we read each department’s own permit pages looking for one, and none publishes a first-review target for remodel permits. The table records what each one does publish and where, so you can check it yourself instead of taking our word for it.
| Jurisdiction | What it publishes on review time | Applies to |
|---|---|---|
| City of Reno | No first-review target on the Reno Building Permits page, read 24 September 2026. A reported result is below the table. | Parcels inside Reno city limits |
| City of Sparks | None. No review time or target on the Sparks Building Permits page or the city’s applications and forms page, both read 24 September 2026. | Parcels inside Sparks city limits |
| Washoe County | None for remodel permits on its Permit Review and Status or Residential Projects pages. Its solar page states an aim of a first review “within 10 business days” for solar PV permits only. All three read 24 September 2026. | Unincorporated parcels |
The City of Reno does report a result. A Development Services memo to the City Council dated 26 May 2026 reports “a 10-business day turnaround for 96% of permits” (read 24 September 2026). That is a city-wide result for past permits, not a target or a promise for yours.
Two things are worth saying about any review figure a department does print. It describes the first pass only, and says nothing about how many passes your file will need. And it moves with permit volume, which in this valley moves with the building cycle.
The six things that actually stall an application
An incomplete set
The most common cause and the most avoidable. A missing site plan, an unsigned application, a structural sheet without a wet stamp, no energy-compliance documentation. None of these are review comments: they stop the file before review.
Scope that moved after the drawings were finished
A layout change agreed in a kitchen conversation and never fed back into the set. The reviewer reviews the set, so when the field work does not match it the correction arrives at inspection instead, a far more expensive place to find it.
Structural work with no calculations behind it
Removing a bearing wall, adding a header, cutting a new opening, adding load above an existing foundation. A reviewer cannot approve a beam on the strength of a note saying it will be fine, and engineering takes its own calendar.
A second agency nobody scheduled
Depending on scope and parcel, plan review is not the only approval: fire review, health-district review where a property is on septic or a well, utility coordination, floodplain or grading review, or a planning-side approval. Each is a separate queue, and discovering one late adds its review time to the middle of the project rather than the end.
Unpermitted prior work
An addition, a conversion or a sub-panel that never had a permit. It surfaces when a reviewer or an inspector looks at the house and has to be resolved before your work proceeds. This is the largest schedule surprise in older housing stock.
Slow answers to corrections
The clock a homeowner can actually see. Comments come back and then sit, waiting on a selection nobody has made, an engineer’s revision, or a decision that needs two people in a room. From the outside, days spent on your side of the loop look exactly like days spent waiting on the city.
ADUs, which are their own review path
Accessory dwelling units are worth naming separately, because their rules are not a single Washoe County code path. The City of Reno administers its own ADU ordinance, the City of Sparks administers its own, and unincorporated county code governs only unincorporated addresses. Setbacks, size limits, parking and owner-occupancy provisions are set by whichever of the three governs your parcel, and they do not agree with each other.
The specific standards, with ordinance sections and the date each was read, belong on this site as Reno Land Development Code 18.03.303 and 18.03.405, with parking at 18.04.708, inside Reno city limits, Sparks Municipal Code 20.03.003 inside Sparks, and Washoe County Development Code 110.306.20 and 110.306.25 on unincorporated Washoe parcels (all three read 30 July 2026), not as a paraphrase. A neighbour’s finished ADU is not a precedent for yours, and neither is a number from a blog. Our ADU and garage conversion page names which authority reviews which addresses.
What a contractor can and cannot do about any of this
The honest division is short. We cannot move a file up a queue, and no relationship at a counter changes a review time. What we can do is make the file one that does not come back:
- Confirm the reviewing authority for the parcel before the schedule is written.
- Assemble the submittal against that department’s current checklist, complete on the first attempt.
- Start engineering early enough that stamped calculations are in the first package rather than the second.
- Identify the second and third agencies at the walkthrough and start those in parallel.
- Answer corrections in days rather than weeks, because that is the half of the loop we own.
- Run the work that legitimately precedes issuance, such as selections, long-lead ordering and site protection planning, so review time is not dead time.
And say plainly which part of the calendar is ours and which is not. A schedule that quietly absorbs plan review into the contractor’s number looks better in week one and worse in month three.
