Buying a lot and building a custom home in Reno can be one of the most rewarding moves you make. It can also feel complex with utilities, permits, and inspections to line up. You want a clear path, realistic timing, and local steps that keep you on schedule and on budget. In this guide, you will see the full timeline from offer to move-in, who to involve at each stage, and the local reviews and utilities that matter most in Reno and unincorporated Washoe County. Let’s dive in.
Reno custom home timeline at a glance
- Due diligence and closing: 2–6 weeks
- Design to permit-ready plans: 2–6 months
- Plan review and permitting: 4–12+ weeks
- Construction to final inspections: 8–15 months
- Move-in and wrap-up: 1–4 weeks
Build a buffer into your plan. Many projects benefit from a 3–6 month schedule cushion and a 10–20% cost contingency due to weather, resubmittals, or utility coordination.
Step 1: Due diligence and closing (2–6 weeks)
Before you close on a lot, confirm which jurisdiction you are in. City of Reno and unincorporated Washoe County follow different rules, even though both use the regional OneNV/Accela system. The City lists submittal checklists, fees, and process details on its Building Permits page.
Order a current boundary and topo survey to understand setbacks and your buildable area. Review title for easements, access, and recorded restrictions. If the property has an HOA, request CC&Rs and architectural rules early so you know what the design board expects.
Do not assume water or sewer service is ready at the curb. Start a will-serve or service-availability check with Truckee Meadows Water Authority. TMWA’s new construction process includes engineering review and a Water Service Agreement, and sometimes water rights or facility charges. Begin at the TMWA new construction portal.
If the lot may need a well or septic, order geotechnical testing and septic feasibility now. Washoe County requires soils and, if applicable, test trenches and health district routing for septic. See the County’s single-family dwelling guidance for what your permit set will need.
Step 2: Design, budgeting, and builder selection (2–6 months)
Decide how you want to design and build. You can work with an architect and bid to builders, or choose a design-build firm for a single team. For highly custom homes, expect more design iterations and longer timelines before permits.
Invite a prospective builder to walk the lot early. A good builder will flag grading needs, retaining walls, utility extension costs, and foundation complexity. Use this input to refine a realistic budget and hold a 10–20% contingency for custom decisions and long-lead items.
If you plan to use a construction loan, talk with a lender now. Many lenders structure draws around build milestones and expect completion within 12–18 months. For an overview of how combined construction-permanent loans are treated in disclosures, review the CFPB’s TRID construction loan guide.
Step 3: Permitting and approvals (4–12+ weeks)
Your permit path depends on location. Both City of Reno and Washoe County accept plan submissions and schedule inspections through OneNV, and the City’s Building Permits page outlines required documents and checklists. Complete submittals shorten first review times.
Typical routing includes building plan check, fire district review, public works or engineering, and utility and health district reviews. If your site is in a Wildland Urban Interface area, expect fire access, hydrant spacing, or sprinkler conditions. For expectations and inspections, see the Truckee Meadows Fire Protection District Development and Inspection Guide.
Plan ahead for fees. Regional Road Impact Fees can be significant, and local water and sewer connection charges are often due near permit issuance. Learn about the RRIF program on the RTC site at the Regional Road Impact Fee page.
Step 4: Utilities and site prep
Water service requires a formal TMWA application and engineering review before meters are set. Some projects involve water rights dedication or facility charges. Starting early with the TMWA new construction process reduces delays.
If public sewer is not nearby, the health district may require septic if it is feasible, or prohibit it if sewer is within a certain distance. Washoe County’s single-family dwelling guidance explains septic testing and routing.
Coordinate power and gas service with your utilities during design. Many builders set temporary power and arrange construction water before site mobilization. Align trenching so you are not opening the same ground twice.
Step 5: Construction and inspections (8–15 months typical)
Most custom builds follow a similar sequence. After site prep and grading, you will move through foundation and footings, framing and roof dry-in, then rough mechanical, electrical, and plumbing. Exterior finishes and interior trim follow, along with final system startups.
Inspections track each phase. The building department and TMFPD schedule many inspections through OneNV. Missed items or failed inspections can lead to reinspection fees and push the schedule, so plan checklists with your builder and trade partners. The TMFPD inspection guide lists common fire-related checkpoints.
If you use a construction loan, draws are tied to milestones and usually require third-party or lender inspections. Many lenders expect completion in 12–18 months, so confirm your timeline and draw schedule before breaking ground.
Step 6: Move-in and closeout (1–4 weeks)
After you pass final inspections, the local building official issues a Certificate of Occupancy. Washoe County codifies CO requirements and sometimes allows temporary occupancy with conditions. You can review CO standards in County Chapter 100 code.
At this stage, transfer utility accounts, collect digital record sets and warranties, and finalize lien releases from subcontractors. Expect your property to be reassessed with the new improvements in the next tax cycle.
Who to involve and when
- Offer and due diligence: real estate agent, title company, licensed surveyor, geotechnical engineer, septic or well consultant if needed, and utility will-serve checks with TMWA.
- Before design completion: architect or designer, civil and structural engineers, prospective builder for lot review and budget, and construction-loan lender prequalification.
- Before permit submission: final drawings, engineered foundation and civil plans, geotech report, utility applications through TMWA, and a pre-application with fire staff if in a WUI area.
- During construction: builder or GC, trade subcontractors, lender inspector, building and fire inspectors, and utility crews.
- Move-in: title or escrow if converting the loan, final lien waivers, CO issuance, utility transfers, and HOA move-in steps if applicable.
Always verify that your contractor is licensed and insured in Nevada. You can look up licenses on the Nevada State Contractors Board site.
Local risks and how to avoid delays
- Utility availability: Water capacity, line extensions, or WSA timing can slow projects. Start early with the TMWA new construction process.
- Septic or well feasibility: Outside sewer areas, health district routing and test trenches can add weeks. See Washoe County’s single-family dwelling guidance to plan testing.
- Plan review resubmittals: Incomplete drawings or missing details add time. Follow the City’s Building Permits checklists and consider a pre-application meeting.
- Fire district conditions: Access, hydrant spacing, and sprinklers can require design changes. Review the TMFPD Development and Inspection Guide early.
- Weather and seasonality: Winter can slow grading, foundations, and exterior work. Aim to schedule major exterior phases for spring through fall when possible.
- Labor and materials: Plan for long-lead fixtures or equipment and keep your contingency intact.
Sample timelines for Reno builds
- Best case: 9–12 months from contract to Certificate of Occupancy on a well-served lot with straightforward approvals.
- Typical case: 12–18 months for most custom single-family homes in Reno and unincorporated Washoe County.
- Challenging case: 18–30+ months with septic or well issues, major grading, complex design, utility extensions, or multiple resubmittals.
