Shelton & Associates is a San Diego tenant-only commercial real estate brokerage representing office, industrial, medical office, life science, and warehouse tenants in lease renewals, relocations, expansions, and purchases. We never represent landlords or list buildings. We help tenants create leverage, reduce total occupancy cost, and negotiate lease terms that protect flexibility. In most transactions, the landlord pays the brokerage fee.
Many businesses search for a San Diego commercial real estate broker without realizing most brokers represent landlords, list buildings, or operate under dual agency. Shelton & Associates represents tenants only. That means our advice, negotiations, and financial modeling are aligned solely with your business, not a landlord’s portfolio.
We negotiate directly with landlords and their brokers to reduce rent, increase concessions, and secure flexible terms that protect your operation. We support every step from market strategy through lease language redlines and move-in execution.




Do you charge tenants?
No. In nearly all cases, the landlord pays our fee as part of the transaction.
Is renewing always cheaper than moving?
Not always. We compare renewal vs. relocation using total cost models; credible move options often improve renewal terms dramatically.
When should we start if our lease expires next year?
Office: typically 9–12 months. Industrial/lab: typically 12–18 months to allow for permitting and build-out.
What if we only want a quick second opinion?
We’ll review your proposal and flag savings opportunities in rent, OPEX/base-year, TI, free rent, and risk clauses.

- Lower effective rent and capped escalations
- Larger TI packages and more free rent
- Flexibility rights (termination, expansion, contraction, sublease)
- Reduced personal guarantee exposure
- Clear, model-based decisions your CFO will trust
-More predictable operating expenses (caps/audit rights where achievable)
