Shelton & Associates is a trusted, San Diego commercial real estate broker specializing exclusively in tenant representation. For nearly 25 years, we’ve helped businesses across UTC, Sorrento Mesa, Mission Valley, Carlsbad, and every major submarket secure the most favorable lease and purchase terms possible.
We negotiate lease renewals, relocations, expansions, and acquisitions for office, industrial, life-science, medical office, and warehouse users, never landlords. Our job is simple: lower your total cost of occupancy and protect your downside through data-driven negotiations and clear financial modeling. Our interests are aligned with yours, and in nearly all cases the landlord pays our fee.
We negotiate directly with landlords and their brokers to reduce rent, capture free rent and improvement allowances, and ensure flexible lease structures that fit your company’s growth. Our services come at no cost to tenants, as landlord commissions cover our fee. With local market expertise, real-time vacancy data, and proven negotiating power, Shelton & Associates delivers measurable savings and leverage for every client we represent.





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: 9–12 months in advance. Industrial/life science: 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.
