Same trip on Google Maps Platform (list prices, for comparison): Routes: Compute Routes Essentials, 3 × $5.00 per 1,000 = $0.015; Dynamic Maps, 240 loads × $7.00 per 1,000 = $1.68. About $1.70 at list price, or $0.00 while usage stays inside Google's monthly free usage cap (10,000 billable events per SKU). Location updates have no Google equivalent and would still need a realtime service.⁴

¹ Location updates: 116 min × 60 s/min = 6,960 s; 6,960 s ÷ 8 s per update = 870 updates. Counted as 1 Realtime message each; even counting send + receive (1,740) it stays far under the 2,000,000 included.
² Supabase Realtime: Free plan includes 2 million messages per month; Pro includes 5 million, then $2.50 per million. Source: supabase.com/pricing, checked Oct 11, 2026.
³ 240 map tile/view loads is an example estimate, not a measurement.
⁴ Google Maps Platform list prices (USD per 1,000 billable events, first paid tier above the free cap): Routes: Compute Routes Essentials $5.00 (free cap 10,000); legacy Directions $5.00 (free cap 10,000); Dynamic Maps $7.00 per map load (free cap 10,000). The comparison treats each of the 240 views as a billable map load, which is an upper estimate. List prices as of Oct 11, 2026 (date checked).

⁵ Typical market range: a standard home inspection costs $296 to $425, national average $344 (Angi, 2026 data: angi.com).
⁶ IRS standard mileage rates: irs.gov/tax-professionals/standard-mileage-rates (business 76¢/mi for Jul 1 to Dec 31, 2026; 72.5¢/mi for Jan 1 to Jun 30, 2026), checked Oct 11, 2026.

⁵ Price per sq ft. Shed: a basic site-built wood shed runs $40 to $100/sq ft, and a typical 10×12 is $5,000 to $9,000 (estimationpro.ai, 2026). Tiny house: $150 to $450/sq ft nationally, and California $325 to $650+ (tinyhomesconnect.com; gsadus.com, 2026). This example uses $60/sq ft for the shed and $325/sq ft for the tiny house.
⁶ Labor: carpenters typically bill $57 to $66/h (oneestimate.ai, 2026), and general carpentry runs $75 to $125/h (homeadvisor.com). This example uses $65/h.
⁷ Equipment day rates: skid steer $180 to $350/day, average $275 (latestcost.com); 2 to 4 ton mini excavator $250 to $300/day (skidsteersdirect.com); 10 to 20 kW generator $200 to $300/day (concretecalculate.com); jobsite delivery $75 to $250 flat (rntr.com). The trip charge uses the IRS 2026 business mileage rate of 76¢/mi (Jul 1 to Dec 31) as an example rate set by the PSP (irs.gov).
⁸ Dumpster: median advertised price is $350 for a 10-yard and $449 for a 20-yard (dumpstercontrols.io, Sep 2026 data). Permits vary by city; a tiny house runs about $1,500 to $3,500 in the Southwest (buildmatinsight.com). The shed permit, materials markup (15%), change orders and prebuilt delivery figures are example values.
⁹ Tax: an example 7.25% (California's statewide base sales and use tax rate, cdtfa.ca.gov) is applied to materials cost only. Local district taxes and how a construction contract is taxed vary, so the PSP confirms the actual tax.
¹⁰ CSLB license requirement: cslb.ca.gov (Before Applying for a License); CSLB press release on AB 2622.
¹¹ Down payment limit: cslb.ca.gov (Home Improvement Contracts); 2026 CSLB Law Book, B&P Code §7159.
