The San Diego Small Business Reality Check
What's great: Weather, talent pool, military/tech/hospitality demand, tourism traffic, affluent customer base in North County and coastal areas.
What's hard: Some of the highest commercial rents in the US, SDG&E rates that are brutal for energy-intensive businesses, California labor regulations that require real attention, and competition from well-funded coastal operators.
The SideGuy truth: San Diego rewards operators who run tight ships. Margin slippage is everywhere — payment fees, energy costs, labor overhead. The businesses that thrive here are the ones that know their numbers cold.
Year 1: Passion. Revenue. This is working.
Year 2: Process. Hiring. Scaling is harder than it looked.
Year 3: Why is my payment processor holding $8,000, SDG&E just raised rates again, and my best employee wants a raise I'm not sure I can afford.
Year 4 with SideGuy: All three of those are solved problems. Text PJ →
The Key Cost Levers for SD Operators
Payment Processing
Most SD businesses overpay by 0.5–1% on processing. At $20k/month, that's $1,200–$2,400/year. Compare all options →
Energy (SDG&E)
SDG&E has among the highest commercial rates in the country. Time-of-use pricing, demand charges, and solar ROI are all worth understanding. NEM 3.0 solar math →
Labor
California minimum wage is $16/hour (2024). San Diego's living wage is effectively higher. Factor total labor cost including payroll taxes, workers comp, and benefits when pricing services.
Commercial Rent
San Diego commercial rents increased 15–25% from 2021–2024 in most areas. Triple-net leases (NNN) mean you also pay property tax, insurance, and maintenance. Know your total occupancy cost, not just base rent.
