Real Estate Developer Site Planning and Feasibility Software
Site planning software for real estate developers. Enter any address to evaluate zoning, setbacks, buildable area, and 1-foot contour topography. Assess development potential before you buy.
Built for Property Evaluation and Due Diligence
Most deals don't fail at closing. They fail when site constraints surface too late.
Properties get acquired blind
Without site-level data, developers commit based on assumptions about what's buildable.
Due diligence takes too long
Waiting for surveys, zoning reports, and feasibility studies delays decision-making.
Potential goes unseen
Lot coverage, topography, and setback constraints aren't visible until it's too late to walk away.
How Developers Evaluate Properties in Minutes
1. Load the Property
Enter the address. The system automatically pulls parcel boundaries, building footprints, zoning data, setback requirements, satellite imagery, and USGS elevation data with 1-foot contour intervals.
2. Assess Development Potential
See buildable area within setbacks. Review lot coverage limits, zoning constraints, and topography. Understand what can realistically be built before engaging architects or engineers.
3. Make Data-Driven Decisions
Compare multiple properties, export professional PDFs for investor presentations, and move forward with confidence backed by real site data.

Frequently Asked Questions
- Is this a design tool or an evaluation tool?
- It's a property evaluation and feasibility tool designed for early due diligence, not final architectural design.
- Can I use this to compare multiple properties?
- Yes. Load different addresses and evaluate buildable potential, zoning constraints, and site conditions across properties.
- Does this work nationwide?
- Yes. Property data is available across the United States.
- Can I share findings with investors?
- Yes. Export professional PDFs with property data, zoning overlays, and development potential analysis for investor presentations.
- Does this show lot coverage and buildable area?
- Yes. The tool calculates lot coverage, displays buildable area within setbacks, and tracks impervious surface coverage to help you understand development limits.
Before a single dollar of capital is committed to a land acquisition, experienced developers conduct rigorous site planning to determine whether a parcel can actually support their intended project. This process — often called due diligence site analysis — examines zoning classifications, setback requirements, easements, utility corridors, and topographic constraints to establish how much of a parcel is truly buildable. A site that looks promising on paper can quickly reveal serious limitations: a 2-acre lot encumbered by a 50-foot drainage easement and 25-foot perimeter setbacks may yield far less usable area than anticipated. For developers evaluating multiple sites simultaneously, a preliminary site layout helps quantify each parcel's potential before committing to surveys, environmental studies, or legal fees. If you're also exploring accessory dwelling unit potential on residential parcels, the ADU feasibility software page covers that specific analysis in detail.
Zoning Constraints and Buildable Area Analysis
Every development project must reconcile the physical dimensions of a parcel with the regulatory envelope imposed by local zoning. Most municipalities define buildable area through a combination of front, rear, and side setbacks, maximum lot coverage percentages, floor area ratios (FAR), and height limits. A parcel zoned R-2 with a 35% maximum lot coverage and 20-foot setbacks on all sides will support a very different project than one zoned MU-C with 80% coverage and zero lot-line allowances. Developers must also account for:
- Recorded easements (utility, drainage, access) that restrict construction
- Flood zone designations under FEMA flood mapping, which may require elevated foundations or exclude portions entirely
- Impervious surface limits tied to stormwater management regulations
- Parking minimums that consume significant buildable area
- Overlay districts imposing additional design or density standards
The International Building Code establishes baseline construction standards, but local zoning ordinances — not the IBC — govern land use and density. Always verify current zoning with the local planning department, as overlay amendments and interim zoning changes are common and not always reflected in online GIS portals.
Practical Advice for Preliminary Site Layouts
One of the most common mistakes developers make during due diligence is conflating gross parcel area with net developable area. A 5-acre site may yield only 2.8 acres of buildable land once you subtract wetland buffers, right-of-way dedications, required open space, and utility easements. Always calculate net area first, then apply coverage ratios and FAR to arrive at realistic program assumptions.
- Sketch multiple massing scenarios — surface parking versus structured parking dramatically changes unit yield
- Identify utility stub locations early; sewer and water connection points often dictate building orientation
- Check for recorded plat restrictions or CC&Rs that may survive rezoning
- Confirm whether the jurisdiction requires a traffic impact analysis threshold that your project density would trigger
- Review EPA stormwater construction permit requirements early — sites over 1 acre require an NPDES permit and a stormwater pollution prevention plan
For projects that include structured parking or shared surface lots, reviewing standard parking layout site plans will help you apply correct dimensional standards for stall widths, drive aisles, and ADA-accessible space ratios before your preliminary layout is too far along to adjust efficiently.
