Site Selection for Small Bay Industrial Development: What the Data Tells You

Here's the difference between small-bay and big-box site selection in one sentence: a 500,000 SF distribution center can succeed in the middle of nowhere if the interchange is good. A 40,000 SF multi-tenant small-bay building lives or dies on the quality of its immediate submarket.

Small-bay tenants are local businesses -- contractors, service companies, small manufacturers, e-commerce operators. Their location decisions aren't about interstate logistics networks. They're about being close to their customers, accessible to their employees, and legal under the local zoning code.

That means site selection for small-bay development demands a completely different analytical framework. Here's every factor that matters, with specific data sources and benchmarks for Texas markets.

The Core Principle: Follow the Tenants, Not the Trucks

Big-box site selection is a logistics exercise. Small-bay inverts the logic entirely. Your tenants' location decisions are driven by:

• Proximity to their customers (the residential and commercial areas they serve)
• Employee commute accessibility (where their workforce lives)
• Visibility and access (easy to find, easy to get in and out)
• Zoning compatibility (can they actually operate without restrictions)

Every data point you evaluate should connect back to one of these four factors.

Factor 1: Zoning and Entitlements

Zoning is the first filter because it's the most binary: either the site works or it doesn't. In Texas, zoning regimes vary dramatically across municipalities, and the nuances can kill a project.

What to verify

Base zoning district: Confirm multi-tenant industrial use is permitted.

• LI (Light Industrial): The most common and typically best fit. Permits warehousing, light manufacturing, contractor yards, and office-warehouse combos.
• HI (Heavy Industrial): Permits everything LI does plus heavier uses. Usually overkill for small-bay but not a negative.
• PD (Planned Development): Requires reviewing the specific ordinance. Some PDs are ideal; others have restrictions that make multi-tenant industrial impractical.
• C-2 or GC (General Commercial): Some commercial zones permit limited industrial uses. Check the permitted use table.

Conditional use restrictions: Even within LI zoning, some municipalities require CUPs for activities common among small-bay tenants: outdoor storage, commercial vehicle parking, auto repair, welding, food production. If 40% of your prospective tenant base needs a CUP, you've got a site selection problem.

Setback and coverage requirements: Small-bay development requires efficient site utilization. If zoning demands 30-foot setbacks on all sides and limits coverage to 50%, your buildable footprint may be too small. Compare the effective building envelope against your target size.

Parking requirements: This is where projects die. Municipal requirements range from 1 space per 500 SF to 1 per 1,000 SF. For a 40,000 SF building with 10 bays, the low end means 80 spaces -- consuming significant site area and potentially limiting building size or yard space.

Real-world demand from small-bay tenants often exceeds code minimums. Contractors with crew vehicles, flex-office tenants with higher employee density, and businesses with walk-in customers all push demand to 4-5 spaces per 1,000 SF. Underestimate parking at your peril -- it's the most common operational complaint in small-bay industrial.

Houston's unique situation: No traditional zoning. Instead, deed restrictions, minimum lot sizes, and ordinances regulate land use. This can be an advantage -- no rezoning process -- but you must carefully review deed restrictions on the specific parcel. They can be more restrictive than municipal zoning elsewhere.

Data sources

• Municipal zoning maps and ordinances (city planning department websites)
• GIS parcel data with zoning overlays (most Texas counties publish these)
• SpanVor's property search includes zoning data from public sources where available

Factor 2: Traffic Counts and Accessibility

For small-bay, site accessibility isn't about interstate proximity. It's about how easily tenants' employees, customers, and delivery vehicles can reach the building daily.

Annual Average Daily Traffic (AADT)

TxDOT publishes AADT counts for every state-maintained road in Texas, updated annually. What to look for:

• Frontage road AADT: Target 10,000-30,000. Enough traffic for visibility and accessibility without congestion that creates access problems.
• Primary arterial AADT: 15,000-50,000. Below 10,000 signals an isolated or underdeveloped area with limited services.
• Highway proximity: Within 2 miles of an interchange with 50,000+ AADT for regional connectivity.

Why AADT matters for small-bay: Your tenants care about local road access, not interstate connectivity. A plumbing contractor dispatches trucks to job sites across their service area. An e-commerce operator needs daily UPS and FedEx access. An auto service shop needs drive-by visibility. AADT captures all of this in a single metric.

Access and turn movements

Beyond traffic volume:

• Turn lanes: For a multi-tenant building generating 80-150 vehicle trips per day, dedicated turn lanes aren't optional -- they're a safety and operational necessity.
• Median breaks: On divided arterials, can vehicles make a left turn in? Many Texas arterials have raised medians with limited breaks, forcing U-turns.
• Truck access: Can a 53-foot trailer reach the site? Even if most tenants don't receive full tractor-trailer deliveries, the occasional one will happen. If you can't accommodate it, you lose an entire tenant segment.
• Traffic signal proximity: A site within 500 feet of a signalized intersection has a meaningful access advantage over one mid-block on a high-speed arterial.

Data sources

• TxDOT STARS: Free online tool with AADT for all state roads
• Municipal traffic count databases: Many Texas cities conduct their own counts
• Google Maps traffic layer: Real-time and historical patterns for peak-hour congestion

Factor 3: Labor Shed Analysis

Your tenants' employees are typically hourly workers -- warehouse staff, technicians, mechanics, production workers -- who are sensitive to commute time and costs. If they can't easily get to your building, your tenants can't staff their operations, and they'll lease somewhere else.

Defining the labor shed

For small-bay in Texas metros, the practical labor shed is a 20-30 minute drive time during morning peak. Beyond 30 minutes, hourly employee retention drops sharply.

What to analyze

Working-age population (18-64): 100,000+ within 20-30 minutes provides a deep talent pool. Below 30,000, your tenants may face chronic staffing challenges.

Household income levels: Small-bay employees typically earn $35,000-$65,000 annually. The labor shed should contain significant numbers in this range. Predominantly high-income surrounding areas mean the workforce lives elsewhere, creating a commute mismatch.

Housing affordability: No affordable housing in the labor shed means workers can't live nearby. This is becoming a real constraint in parts of Austin and some DFW suburbs where residential prices have outpaced wages.

Competing employers: Heavy competition for the same workforce drives up wages and turnover. Some clustering is healthy -- it indicates an established industrial workforce. Too much, and your tenants are fighting for every hire.

Public transit access: Limited in most Texas markets, but METRO bus routes in Houston, DART in Dallas, and CapMetro in Austin can meaningfully expand the labor shed for workers without vehicles.

Data sources

• Census ACS: Demographic data by tract or ZIP -- age, income, education, commute patterns
• ESRI Business Analyst: Drive-time polygons with demographic profiles
• OnTheMap (Census LEHD): Shows where workers live relative to where they work
• Google Maps isochrone tools: Quick labor shed delineation

Factor 4: Proximity to Demand Generators

Small-bay tenants serve specific local demand generators. The closer your building is to those generators, the more desirable it is.

Key demand generators

Residential growth areas: Contractors and home service businesses need to be within 15-20 minutes of active residential construction. Texas's strongest growth corridors:

• Northern DFW (Celina, Prosper, Princeton, Anna)
• Western Fort Worth (Weatherford, Aledo, Hudson Oaks)
• Northwest Houston (Tomball, Magnolia, Hockley)
• North Austin (Leander, Liberty Hill, Jarrell)
• Northeast San Antonio (Schertz, Cibolo, New Braunfels)

Commercial and retail districts: Cleaning, maintenance, pest control, catering, and food distribution businesses need proximity to the commercial areas they serve.

Healthcare facilities: Medical supply, device distribution, and healthcare service providers cluster near hospital campuses.

Last-mile logistics hubs: E-commerce tenants prioritize proximity to FedEx, UPS, and USPS facilities. Within 10 minutes of a major carrier hub offers meaningful logistics advantage.

Educational institutions: Community colleges and trade schools generate workforce. Sites near Texas State Technical College, Tarrant County College, or San Jacinto College benefit from skilled labor proximity.

Quantifying proximity

For each demand generator category, calculate drive time from the candidate site to the nearest three to five. A site within 15 minutes of multiple generators scores higher than one 25+ minutes from all of them.

Factor 5: Highway and Infrastructure Access

Highway access still matters. Most tenants need to reach customers across a metro, receive carrier shipments, and dispatch vehicles across a wide geography.

Benchmarks

• Interstate or state highway: Within 3 miles of an interchange
• Highway AADT: 50,000+ on the nearest highway -- I-35, I-10, I-45, US-290, Loop 820, Beltway 8, Loop 1604
• Frontage road access: Visibility plus accessibility -- the ideal combination in Texas

Utility infrastructure

• Electrical: Confirm three-phase power availability. Extension costs and timelines can be significant. Contact Oncor, CenterPoint, or TNMP for a service availability letter.
• Water and sewer: Municipal service preferred. Well water and septic are generally unsuitable for multi-tenant development.
• Natural gas: Required for manufacturing, commercial kitchens, and heating. Check Atmos Energy in most Texas markets.
• Fiber internet: Increasingly critical. Many tenants run cloud-based operations, VoIP, and online storefronts that require reliable high-speed connectivity.

Factor 6: Competitive Landscape

Your building has to compete with what already exists -- and what's coming -- in the submarket.

Competitive supply analysis

Inventory within 5 miles: How much small-bay space exists? Catalog everything under 100,000 SF with bays under 20,000 SF. SpanVor's property search makes this straightforward -- filter by building size, type, and geography to instantly see the competitive set.

Vacancy: Below 4%? Supply-constrained, can absorb new product. Above 7%? Risky unless you've got differentiated product.

Rent levels: Your pro forma rents need to be achievable based on what's leasing now. If the best product within 5 miles gets $12 PSF NNN, don't underwrite $15 without compelling evidence of a market shift.

Age and quality: If existing inventory is predominantly 1980s-1990s with deferred maintenance, new construction with modern amenities (LED, climate control, dock-high, high electrical) can command a 20-30% premium. If competing supply is already high-quality, your differentiation opportunity shrinks.

Pipeline: Other developers building or planning small-bay nearby? Simultaneous delivery creates lease-up risk. Check municipal permits and CRE platforms.

Positioning strategy

• Premium in an underserved market: New Class A in a submarket of aging Class B/C. Command 20-30% rent premiums.
• Cost-efficient in a high-rent market: Smaller bays (1,500-3,000 SF) at competitive monthly totals. Capture the price-sensitive segment.
• Specialized product: Extra power for manufacturing, enhanced loading, high office ratios -- whatever's underrepresented in existing supply.

Factor 7: Land Cost and Development Economics

Site selection ultimately comes down to whether it pencils.

Texas land cost benchmarks

• DFW: $8-$25 PSF for entitled industrial land. South DFW and Ellis County at the low end, Frisco/Plano at the top.
• Houston: $6-$20 PSF. Northwest and Katy higher, southeast and Baytown lower.
• Austin: $12-$35 PSF. Highest in Texas for industrial, driven by limited supply and competing residential demand. Georgetown and Hutto offer relief.
• San Antonio: $5-$15 PSF. Most affordable major Texas metro, particularly the northeast corridor.

The quick feasibility test

1. Land cost per building SF: Total land cost divided by planned building area. Target under $25/building SF. Above $35, likely too high for small-bay economics.
2. Construction cost: $85-$130 PSF hard costs depending on finish level, height, and configuration. Add 15-20% for soft costs.
3. All-in development cost: $120-$180 PSF in most Texas markets.
4. Required rent: All-in cost times target yield. At $150 PSF targeting 8%, you need $12.00 PSF NNN. Is that achievable?
5. New construction premium: Typically 10-20% over existing product. If comps are at $11, you can reasonably underwrite $12.50-$13.00.

The counterintuitive insight

High land costs are bad for development but great for existing owners. In submarkets where land has appreciated past the feasibility threshold, existing buildings become more valuable because new supply can't be economically delivered. That's one of the structural advantages of investing in existing small-bay versus ground-up.

A Site Selection Scorecard

When comparing candidates, use standardized scoring:

| Factor | Weight | Key Metric | |---|---|---| | Zoning and entitlements | 20% | Permitted uses, parking, CUP requirements | | Traffic and accessibility | 15% | AADT, turn movements, truck access | | Labor shed | 15% | Working-age population within 25-min drive | | Demand generators | 15% | Drive time to residential, commercial, healthcare | | Highway / infrastructure | 10% | Distance to interchange, utility availability | | Competitive landscape | 15% | Vacancy, rent levels, pipeline within 5 miles | | Land cost and economics | 10% | Land PSF, pro forma feasibility |

Rate each site 1-5 per factor, apply weights, compare composites. Above 4.0 is a strong candidate. Below 3.0, walk away. Between 3.0 and 4.0, the deal depends on how strong the top factors are and whether the weak ones can be mitigated.

How AI Changes the Game

Traditional site selection means an analyst spending 40-80 hours per site collecting zoning data, pulling traffic counts, running demographics, cataloging comps, and building a pro forma. Five candidate sites? That's a significant investment before you've made an offer.

AI-driven platforms compress this dramatically. SpanVor aggregates property-level data across all 254 Texas counties and applies machine learning to surface patterns. While primarily used for identifying acquisition opportunities, the same dataset powers development site selection:

• Competitive supply mapping: Every industrial property within a defined radius, filtered by size, age, and type. Days of manual research in minutes.
• Ownership and transaction patterns: Which properties traded recently and at what values, providing comp evidence for land pricing.
• Market density visualization: The interactive map reveals where development clusters and where supply gaps exist.

Combined with TxDOT data, Census demographics, and municipal zoning, tools like SpanVor let you evaluate a candidate site in hours instead of weeks.

Case Study: I-35 Corridor Site

A 5-acre parcel between San Antonio and New Braunfels, zoned LI.

Zoning: All target uses permitted including outdoor storage. Parking at 1 per 750 SF. No CUPs needed. 60% coverage. Score: 5/5.

Traffic: 4-lane arterial frontage with 22,000 AADT. Turn lanes exist. I-35 interchange 1.5 miles away at 95,000 AADT. Score: 4/5.

Labor shed: 85,000 working-age residents within 25 minutes. Median household income $58,000. Score: 4/5.

Demand generators: 3 master-planned communities within 10 miles, regional medical center 8 minutes away, FedEx Ground 12 minutes. Score: 5/5.

Infrastructure: I-35 at 1.5 miles. Three-phase power. Municipal water/sewer. Fiber from two providers. Score: 5/5.

Competitive landscape: 1.2M SF of small-bay within 5 miles, mostly 1990s vintage. 3.8% vacancy. $10.50 PSF NNN average. No new small-bay in pipeline. Score: 5/5.

Land cost: $9 PSF ($1.96M for 5 acres). Planned 40,000 SF building. Land per building SF: $49. Construction: $110 PSF. All-in: ~$165 PSF. Required rent at 8% yield: $13.20 PSF NNN. That's a 26% premium over existing -- aggressive but potentially achievable in a supply-constrained market. Score: 3/5.

Composite: 4.4/5.0 -- a strong site. Primary risk is land cost pushing required rents above current market. Mitigate by pre-leasing 2-3 bays before breaking ground to validate the rent assumption.

The Bottom Line

Site selection for small-bay development rewards discipline. The developers who consistently win are those who rigorously evaluate zoning, traffic, labor sheds, demand generators, competitive supply, and economics before committing capital -- and who use modern tools to compress the process.

In Texas, the site selection challenge isn't finding markets with demand. It's finding the specific parcels where zoning, access, infrastructure, and economics all converge.
