The 20 Questions That Determine Whether Your Project Works
Every rural estate project in Loudoun County runs through the same set of gatekeeping questions. The answers determine the permit path, the timeline, the total cost, and whether what you want to build can be built where you want to build it.
Projects that work have answers to all twenty before design begins. Projects that stall typically discover the hard answers mid-design — after significant investment in drawings that must be revised.
This checklist is organized across five domains: zoning, soil and septic, access, infrastructure, and program. Work through each section before committing to a design contract.
---
Domain 1: Zoning (Questions 1-5)
**1. What is the exact zoning designation of the parcel?**
Do not rely on the listing description. Pull the current Loudoun County GIS parcel data and confirm the zoning designation. AR-1, AR-2, A-3, A-10, and JLMA designations each carry different permitted uses, minimum setbacks, and lot coverage limits. Confirm before every other question.
**2. Does the 2024 amendment's prime farmland restriction apply to this parcel?**
The 2024 Loudoun County Zoning Ordinance created tighter building envelope constraints on approximately 685 parcels where 70% or more of soils are classified as prime farmland. If your parcel is in this category, the building envelope where you can place structures is more constrained than the general AR-1 standards suggest. Check with Loudoun County Planning or a land use attorney before designing.
**3. Are there conservation easements or deed restrictions recorded against the parcel?**
Pull the full chain of title including all recorded easements. Conservation easements held by land trusts — Loudoun Wildlife Conservancy, Northern Virginia Conservation Trust, Virginia Outdoors Foundation — restrict development in ways that may not be apparent from a visual review of the property. The restriction language varies: some easements permit a primary residence within a defined building envelope; others prohibit any additional construction whatsoever. Read the full easement document.
**4. What uses are permitted by right versus by Special Exception?**
Primary residences, accessory dwellings, agricultural structures, farm wineries, and farm breweries are by-right on AR-1 in most cases. Commercial event venues, agritourism operations above a certain scale, and specific agricultural businesses may require a Special Exception — a discretionary approval that adds 3-6 months and is not guaranteed. Confirm which category your intended use falls into before designing around it.
**5. What are the minimum setbacks for all proposed structures?**
In Loudoun County's AR-1 district, setbacks from property lines, road rights-of-way, and stream buffers must be met for every structure. On irregularly shaped parcels or parcels with multiple frontages, setback compliance can significantly constrain where structures can go. Map all setbacks against the site before placing any structure in a design.

Domain 2: Soil and Septic (Questions 6-9)
**6. Has a soil evaluation and perc test been completed?**
The VDH soil evaluation establishes whether a conventional septic system ($12,000-$25,000) or an engineered alternative ($30,000-$80,000+) is required. It also establishes where on the parcel the septic drain field can go — which constrains building placement. This evaluation must happen before design places the primary residence at a specific location.
**7. Does the preferred building site have adequate soil in the required setback zones?**
The septic drain field must maintain minimum setback distances from structures, property lines, wells, and water features. If the preferred building location does not have adequate soil area within required setbacks, the building must move or the septic system must be engineered to a smaller footprint at higher cost. This determination cannot be made without the soil evaluation.
**8. Is the septic system sized for the full program — not just Phase 1?**
On multi-structure estates, the septic system installed with the primary residence must have adequate reserve capacity for accessory dwellings, guest houses, and any hospitality uses planned for later phases. Adding capacity to an existing system is possible but expensive. Designing for full program capacity from the beginning costs a fraction of the retrofit.
**9. If an engineered septic is required, which system type has been selected and permitted?**
Drip dispersal systems, mound systems, aerobic treatment units, and recirculating media filter systems each have different site footprint requirements, maintenance obligations, and costs. The selection of system type must be confirmed before final site plan layout, because the system footprint occupies land that cannot be used for other purposes.

Domain 3: Access (Questions 10-12)
**10. Does the proposed driveway entrance have adequate VDOT sight distance?**
Assess the sight distance in both directions from the proposed entrance at the posted speed limit. If obstruction from vegetation, curves, or grade limits sight distance below the VDOT standard for that road speed, the entrance location or the obstruction must change. Determine this before submitting the VDOT Land Use Permit application.
**11. Is the proposed driveway route feasible from a grade and drainage standpoint?**
Have a civil engineer review the proposed driveway route for maximum grades (VDOT recommends no more than 10% for a private driveway, 8% preferred), drainage patterns, and culvert requirements. A driveway that looks straightforward on a map may cross a drainage swale, require substantial cut and fill, or have grade issues that add significantly to construction cost.
**12. Are there any easement or right-of-way constraints on the proposed access route?**
Some parcels access public roads only through easements across adjacent properties. Confirm that easement language permits the driveway width, surface type, and traffic volume you intend. Confirm maintenance obligations. On multi-structure estates, confirm that the easement permits the service and agricultural traffic the full program will generate.

Domain 4: Infrastructure (Questions 13-16)
**13. Where is the nearest Dominion Energy transformer and what is the electric service extension cost?**
Contact Dominion Energy Virginia with the parcel address and request a service availability and extension cost estimate. Do this before finalizing the site plan, because the cost of service extension is highly sensitive to the distance from the nearest transformer — a distance that can be reduced by selecting a building site closer to the road.
**14. Is fiber or broadband service available at the parcel address?**
Check with Xfinity, Verizon FiOS, and local fiber providers for the parcel address. In parts of western Loudoun and Clarke County, fiber is not available. Satellite broadband (Starlink) is a viable alternative but has different performance characteristics. Confirm before assuming connectivity requirements are met.
**15. Where does propane delivery access the property?**
In the absence of natural gas service (which is not available in most of rural Loudoun County), propane is the primary heating and cooking fuel for rural estate construction. The propane tank must be accessible to a delivery vehicle at regular intervals. Site the tank location and confirm delivery access before finalizing the site plan.
**16. Has a preliminary infrastructure cost estimate been developed?**
Before design begins, the total site infrastructure cost — driveway, utilities, well, septic, grading — should be estimated at the order-of-magnitude level. This estimate defines the available budget for the structure. It is the difference between designing to a budget that works and designing to a budget that forces scope cuts during construction documents.

Domain 5: Program and Feasibility (Questions 17-20)
**17. Is the full construction program confirmed and feasibility-tested against the site?**
Document every structure you intend to build — primary residence, guest house, barn, pavilion, pool, future phases — and map them against the site's constraints (setbacks, drain field location, topography, access routes, view corridors). This exercise frequently reveals conflicts that must be resolved before a dollar is spent on design.
**18. Has a preliminary total project budget been developed across all seven cost categories?**
Land acquisition, site infrastructure, soft costs, structure, fixed equipment, landscape, and contingency. The per-square-foot structure cost is one of seven categories — and it represents 60-70% of total project cost on a rural estate. The other 30-40% must be budgeted before design begins.
**19. Is the construction timeline consistent with the owner's occupancy goals?**
From preconstruction engagement through certificate of occupancy, plan 16-24 months for a primary residence on rural land in Loudoun County. Multi-structure estates and hospitality projects extend this timeline. If a specific move-in date drives the project, work backward from that date to confirm when design must begin, when permits must be submitted, and when construction must start.
**20. Has a design-build partner been selected who has direct experience on comparable rural projects in Loudoun County?**
The final question. Rural estate construction in Loudoun County requires a team that knows the regulatory environment, the subcontractor network, and the site challenges specific to this region. This knowledge is not transferable from suburban residential or commercial experience. Verify directly.

FAQ
**Q: How long does it take to answer all 20 questions?**
With the right team, 4-6 weeks. Zoning confirmation and easement review take 2-4 weeks. Soil evaluation takes 1-2 weeks to schedule and complete. VDOT access assessment, utility investigation, and civil engineering preliminary review can run concurrently. The full checklist can be completed in a single focused preconstruction engagement before the design contract is signed.
**Q: What happens if I can't answer one of these questions?**
The question identifies a gap that must be resolved before proceeding. Do not skip questions and hope the answer is favorable — unfavorable answers discovered mid-design cost more to respond to than unfavorable answers discovered before design begins. If a question cannot be answered, identify why and resolve the gap.
**Q: Can a design-build firm help me answer these questions?**
Yes. Hearthstone's preconstruction engagement ($7,500-$12,500) is structured specifically to answer these questions before design begins. The engagement includes site evaluation, zoning review, preliminary cost framework, and schedule development. The output is a validated project foundation — not just a pile of open questions.
