Make Your Orange County Landlord Compete for You
Peninsula Commercial Real Estate Group provides tenant representation across Orange County, covering Irvine, Newport Beach, Costa Mesa, Santa Ana, Anaheim, Huntington Beach, Orange, Lake Forest, Mission Viejo, and Tustin. Corina Irvin, Founder & Principal, started the firm in 2019 and personally negotiates every lease. Her track record spans more than $750 million across 10 million-plus square feet.
A Renewal Offer Is a Guess About How Much Effort You’ll Make
Most Orange County tenants negotiate against exactly one building. The one they already sit in.
The renewal notice shows up. The number is higher than last time. Someone checks it against what the landlord says the market is doing. Then it gets signed for another five or ten years.
Here is the method Peninsula CRE Group rejects: negotiating a renewal before touring competing buildings. It feels like the efficient choice. It is the most expensive shortcut a tenant can take. No landlord improves an offer when nothing is pulling their tenant away.
There is a second assumption worth naming out loud. Many tenants believe the broker who listed the building is helping them. That broker’s duty runs to the owner. Most tenants never think to ask which side anyone is on.
Peninsula CRE Group takes no landlord listings anywhere in Orange County. No property management contracts either. When Corina sits down with your landlord, no other client’s interests are pulling at her.
Leverage is not how hard someone pushes in a meeting. Leverage is a real building, already toured, that your landlord knows you could move into.
Ten Cities. Three Corridors. That’s Where Your Leverage Comes From
Orange County reads like one market on a map. It does not behave like one.
-
The Airport Corridor
Irvine, Newport Beach, Costa Mesa, and Tustin. These cities ring John Wayne Airport and hold the county’s deepest concentration of Class A office space.
-
The North and Central Corridor
Santa Ana, Anaheim, and Orange. County government, courts, hospitals, and the largest industrial districts in Orange County all sit here, connected by the 5, 22, 55, 57, and 91.
-
The Coast and South County Corridor
Huntington Beach, Lake Forest, and Mission Viejo. Coastal industrial buildings, business park inventory, and suburban professional and medical office run along the 405 and the 5.
A landlord is at their strongest when you only shop inside their corridor. The moment a credible building appears one corridor over, the conversation changes. Concessions that were unavailable last week become available this week.
That is why Peninsula CRE Group covers all ten cities. Not to plant a flag. So the shortlist Corina puts in front of your landlord holds buildings that landlord actually has to worry about.
You do not have to move to benefit from this. Plenty of clients stay right where they are, on better terms, because someone showed the landlord what leaving would have looked like.
Every Lease Is Worked by a Principal. Every Time
Corina Irvin has spent 15+ years in commercial real estate. Eight of those as a Director at Cushman & Wakefield in New York City and Los Angeles. Five more at Grubb & Ellis in Los Angeles. She holds a BS in Business Administration from USC with an emphasis in Real Estate Finance.
She was a conference speaker at the GlobeSt Women of Influence event and an Honoree at the CREi Women of Influence Summit, 2022 through 2025.
At many large firms, a senior name wins the assignment and a junior broker runs it. At Peninsula CRE Group, you work directly with a principal. Whether you need 2,000 square feet in Tustin or 100,000 in Anaheim, it is the same principal, start to finish.
Cost stops most tenants before they start. Representation is almost always paid by the landlord out of the listing commission. For most tenants, senior-level representation costs nothing out of pocket.

Tenant Representation in Irvine — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Irvine for companies leasing office, medical office, retail, industrial, and combined office/warehouse space.
Irvine is a master-planned city, and that shapes every negotiation inside it. A large share of the commercial inventory sits under concentrated, master-planned ownership, which means one owner often controls both the building you want and the building you would use as leverage against it.
The office market splits in two. The Irvine Business Complex sits next to John Wayne Airport and carries the older, denser inventory, much of it reworked over the years. The Irvine Spectrum sits where the 5 and 405 meet, fed by the 133, 241, and 261 toll roads, and carries the newer campus product. UC Irvine anchors a research and technical workforce, and the tenant base follows: technology companies, medical device firms, engineering and design operations, professional services, and healthcare practices.
Those two office markets price differently and negotiate differently. A tenant who tours only one never learns what the other would have paid to win them.
Corina Irvin handles Irvine leases personally. She tours across both, then develops credible alternatives in the neighboring airport-corridor cities. Once a landlord knows a competing building is in play, the terms available to you change.
She reads the whole lease, not just the rate. Tenant improvement allowances, operating expense pass-throughs, free rent, expansion rights, and exit terms all carry money. Rent is the number everyone watches. The other terms are where a decade of cost quietly builds up.
If your Irvine lease expires in the next 6 to 18 months, that is the window where representation changes the outcome.

Tenant Representation in Newport Beach — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Newport Beach for businesses leasing office, medical office, and retail space, negotiated personally by Corina Irvin.
Newport Beach is an address market, and it has two of them. Newport Center holds the tower inventory around Fashion Island, where the view and the postcode are part of what a tenant is buying. A second office cluster sits at the airport end of the city, minutes from John Wayne, with a different rent structure and a different kind of building. The 73 toll road and the 55 connect them.
The tenant base leans heavily toward wealth management, law firms, private equity and investment companies, accounting practices, and real estate firms. Medical office demand concentrates near Hoag Hospital. Retail runs along the Balboa Peninsula and through the Pacific Coast Highway corridor in Corona del Mar.
Tenants arrive here having already decided they want Newport Beach. Landlords understand that, and opening terms reflect it.
Corina’s job is to keep your preference from becoming your negotiating position. She tours both Newport office markets and builds real options in the surrounding airport-corridor cities. Then the landlord has to earn the lease instead of assuming it.
She negotiates the full document. Tenant improvement dollars, operating expense treatment, free rent, renewal rights, and exit flexibility all get worked. Client-facing businesses sign long leases here, so the terms that decide year seven get attention at signing.
Medical requirements get specific fast. Patient flow, plumbing and power, parking ratios, ADA compliance, and whether the build-out you need is permitted in that building at all. Corina asks those questions before you sign, not after.
ORANGE COUNTY · TENANT REPRESENTATION
Tenant Representation in Costa Mesa — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Costa Mesa for companies leasing office, creative office, medical office, retail, industrial, and combined office/warehouse space, with Corina Irvin negotiating every lease directly.
Costa Mesa holds two very different inventories inside one small city. South Coast Metro carries the Class A towers clustered around South Coast Plaza and Segerstrom Center for the Arts, drawing professional services, finance, and corporate tenants. A few minutes west, older industrial buildings along the Baker and Placentia corridors have been converted into creative office, and consumer brand, apparel, design, and media companies cluster there. Orange Coast College and Vanguard University sit inside the city, and the 405, 55, and 73 all converge, with John Wayne Airport minutes away.
Two inventories means tenants routinely compare the wrong set of buildings. A company that belongs in a converted creative building prices itself against tower rents, or the reverse. Either way, the comparison that would have created leverage never happens.
Corina starts by defining what your operation actually needs, then tours across both inventories. What comes back is a shortlist of buildings that fit, priced against each other.
Converted buildings deserve extra scrutiny. Power, ceiling height, loading, parking ratios, and permitted use are things you learn by walking the property, not by reading a flyer. Bow-truss ceilings and skylights photograph beautifully and can hide practical problems.
The build-out conversation is where tenants most often lose money in this city. Tenant improvement allowances and construction terms get negotiated as part of the lease, not discovered after it.

Tenant Representation in Santa Ana — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Santa Ana for companies leasing office, medical office, retail, industrial, and combined office/warehouse space, negotiated start to finish by Corina Irvin.
Santa Ana is the county seat, and the civic center changes what leases here. County administration, the courts, and the legal and professional firms that need to be near them occupy a large share of the office inventory, and proximity to the courthouse is a real requirement rather than a preference. MainPlace and the historic downtown anchor retail. West and south of the civic core sits one of the deepest industrial and combined office/warehouse bases in Orange County. Santa Ana College is here, the Santa Ana Regional Transportation Center connects Metrolink and Amtrak, and the 5, 22, 55, and 405 converge at the interchange locals call the Orange Crush.
Santa Ana carries the widest range of price points and building ages in the county. That range is an advantage for a tenant who compares properly and noise for one who does not.
Corina does the comparison for you. She tours, shortlists, and reduces a crowded market to the buildings that genuinely fit your operation. Then she negotiates them against each other.
Older buildings often need work to function for a modern tenant. That is a negotiating opportunity, not a disqualifier. Tenant improvement dollars, free rent, and construction terms are where the value gets recovered, and those are negotiated before you sign.
Peninsula CRE Group holds no landlord listings in Santa Ana and no property management contracts. When Corina says a building has a problem, no second client softens that assessment.
ORANGE COUNTY · TENANT REPRESENTATION
Tenant Representation in Anaheim — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Anaheim for businesses leasing industrial, combined office/warehouse, office, medical office, and retail space, handled personally by Corina Irvin.
Anaheim runs on two economies at once. The visitor economy anchors the south end of the city around the Disneyland Resort, the Anaheim Convention Center, Angel Stadium, and Honda Center, with the Platinum Triangle adding density around them. The northeast is a different city entirely: Anaheim Canyon holds one of the largest industrial districts in Orange County, with manufacturing, distribution, and combined office/warehouse users along the 91. The 5 and 57 carry the rest, and the Anaheim Regional Transportation Intermodal Center connects Metrolink and Amtrak.
Industrial requirements here are operational, not aesthetic. Loading capacity, clear height, power, yard space, cold storage, and drive time to the freeway and to your customers. Get those wrong and the building costs you money every day you occupy it.
Corina runs these searches with the technical requirement leading, not the rent number. She has negotiated combined office/warehouse transactions where highly specific power, HVAC, and operational specs decided which buildings qualified at all.
Once the qualifying buildings are identified, she negotiates them against each other. A landlord who assumes you have nowhere else to go behaves very differently from one watching a competing building bid for your operation.
Retail and hospitality-adjacent requirements near the resort district work on a different clock, with visibility, access, and seasonal traffic driving the decision. Same method: define the requirement, tour the real options, then negotiate.
Requirements here run from 2,000 square feet to 100,000 and beyond, and no lease size gets handed to someone junior.
ORANGE COUNTY · TENANT REPRESENTATION
Tenant Representation in Huntington Beach — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Huntington Beach for companies leasing industrial, combined office/warehouse, office, medical office, and retail space, with Corina Irvin negotiating every lease herself.
Huntington Beach has had a manufacturing and engineering base for decades, concentrated in the industrial corridors in the northwest of the city along Gothard, Springdale, and the streets feeding Bolsa Chica and Edinger. Consumer brand and apparel companies built a presence here too. Retail runs through Bella Terra, Pacific City, and the Main Street district near the pier, with Beach Boulevard and Pacific Coast Highway carrying the traffic and the 405 running along the top of the city.
Class A office inventory here is limited compared with the airport corridor, and industrial space is tightly held. That combination is exactly why the requirement has to be defined before the search starts. Tenants who begin by browsing whatever is listed end up compromising on the thing that mattered most, because the listing they found was the only one they saw.
Corina runs the search from your side. She identifies which Huntington Beach buildings genuinely satisfy your operation, then develops credible options in the neighboring coastal and North County cities. Your landlord finds out that other buildings want your business.
Loading, power, clear height, and yard access are things you confirm by walking a property. She walks them with you, and she asks what the building will need to do for you in year five, not just on move-in day.
Start 6 to 18 months before expiration. Inside 90 days, your landlord knows you are out of runway, and so are your options.
ORANGE COUNTY · TENANT REPRESENTATION
Tenant Representation in Orange — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in the City of Orange for businesses leasing medical office, office, retail, and industrial space, negotiated personally by Corina Irvin.
Orange holds one of the most concentrated healthcare clusters in Southern California. UCI Medical Center, Providence St. Joseph Hospital, and CHOC sit within blocks of each other near The City Drive and West Chapman, and medical office demand around those campuses is persistent. Chapman University anchors the center of the city. Old Towne Orange, one of the largest historic districts in California, holds small converted retail and office buildings that suit boutique firms and practices, with historic-district requirements that affect what you can change inside them. The Outlets at Orange draws regional retail traffic, and the 5, 22, 55, and 57 all meet nearby.
Medical office is where tenants here lose the most money, because build-out drives the economics. Patient flow, specialized equipment, plumbing and power, ADA compliance, and shell condition all decide which suites are genuinely viable. Two spaces at the same rent can differ by a wide margin once construction is priced.
Corina has completed medical office transactions and knows which questions to ask early. She identifies the suites that actually work for your practice, then negotiates build-out terms alongside the rate.
Proximity to a hospital campus is valuable, and landlords price against that. The counter is a shortlist that includes credible options slightly farther out, so the preferred building has to compete to keep you.
Peninsula CRE Group takes no landlord listings in Orange and no property management contracts. Corina’s only client in the room is you.
ORANGE COUNTY · TENANT REPRESENTATION
Tenant Representation in Lake Forest — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Lake Forest for companies leasing industrial, combined office/warehouse, office, medical office, and retail space, negotiated start to finish by Corina Irvin.
Lake Forest is business park country. The commercial inventory concentrates in the park corridors along Bake Parkway, Rockfield, and Muirlands, and up into Foothill Ranch, serving light manufacturing, medical device, consumer product, distribution, and professional services tenants. The 5 runs along the western edge and the 241 toll road along the eastern, which is why South County distribution operations lease here rather than farther inland.
Business park buildings photograph as interchangeable. They are not. Clear height, power capacity, loading configuration, HVAC, parking ratio, and truck turning radius vary building to building inside the same park, and those differences decide whether your operation runs smoothly or fights the building every day.
Corina walks the buildings and pressure-tests fit against how you actually operate. Only the properties that qualify make the shortlist.
Then she negotiates them against each other, and against credible options in the neighboring South County and airport-corridor cities. A landlord negotiates differently with a tenant who has somewhere real to go.
Growing companies outgrow business park space faster than they expect. Expansion rights, contraction options, and exit terms are worth more here than most tenants realize at signing, and the time to negotiate them is before the first lease, not during the second.
Requirements run from 2,000 square feet to 100,000 and beyond, and Corina works all of them personally.
ORANGE COUNTY · TENANT REPRESENTATION
Tenant Representation in Mission Viejo — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Mission Viejo for businesses leasing medical office, office, and retail space, with Corina Irvin personally handling every negotiation.
Mission Viejo is a master-planned South County city, and its commercial inventory reflects that. Professional and medical office concentrates along Crown Valley Parkway and La Paz Road, with a medical cluster built up around Providence Mission Hospital. The Shops at Mission Viejo anchors retail. Saddleback College sits in the center of the city. The 5 carries the commute, and the tenant base leans toward medical practices, professional services firms, financial and insurance companies, and businesses serving the surrounding South County population.
The inventory here is smaller than in the airport corridor, and that is the negotiating problem. When a market has few available buildings, a landlord assumes their tenant has nowhere to go. Usually the landlord is right, because most tenants never look.
Corina looks. She tours the qualifying Mission Viejo space, then develops real alternatives in the neighboring South County cities. The renewal offer that arrives after that work is done usually looks different from the one that arrived before it.
Practices and professional firms stay put here for a long time, because the location becomes part of the client relationship. Staying is frequently the right answer. It is only the right answer at the right price, and that price is impossible to identify from inside a single building.
Medical requirements get particular attention. Patient flow, equipment, plumbing and power, ADA compliance, and build-out cost all determine which suites are genuinely viable, and which ones only look affordable until construction is priced.

Tenant Representation in Tustin — Peninsula CRE Group
Peninsula CRE Group provides tenant representation in Tustin for companies leasing office, medical office, retail, industrial, and combined office/warehouse space, negotiated personally by Corina Irvin.
Tustin carries two generations of building stock side by side. Tustin Legacy, the redevelopment of the former Marine Corps Air Station, has delivered newer commercial and retail product, including The District. Older industrial and combined office/warehouse buildings run along Red Hill Avenue and Edinger, and Old Town Tustin holds small historic retail and office space. The Tustin Metrolink station sits at the south end of the city, and the 5, 55, and 261 all serve it. John Wayne Airport is minutes away, which puts Tustin inside the airport office corridor without airport-corridor pricing.
New product and older product negotiate differently. Newer buildings compete on condition and amenity and hold firmer on rate. Older buildings compete on economics and on what a landlord will fund to make the space work. Tenants who shop only one generation never see the trade they are actually making.
Corina tours both. She builds a shortlist across the range that fits your operation, then negotiates those buildings against each other and against options in the surrounding airport-corridor cities.
She negotiates the terms that carry long-term cost: tenant improvement dollars, operating expense pass-throughs, free rent, expansion rights, and exit terms. Those decide whether a lease protects you in year seven or works against you.
Peninsula CRE Group takes no landlord listings in Tustin and no property management assignments. Nothing pulls Corina’s read on a building in another direction.
If your Tustin lease is inside 18 months of expiring, now is when the useful work happens.
Who Peninsula CRE Group Is Not Built For
Some tenants will be better served somewhere else, and it is worth saying so plainly.
-
If you want to deal directly with the listing broker because it feels like it will save you money
This is not a fit. That broker works for the owner. Tenants who skip independent representation do not save a commission — the landlord pays it either way. They just negotiate with nobody on their side.
-
If you want a large national brokerage team experience, with a senior name on the pitch and a junior broker doing the work
Peninsula CRE Group is the wrong choice. There is no team to hand your lease to. There is Corina.
-
If you want the fastest possible close with no touring and no comparison
She will say so rather than take the assignment. The comparison is the product. Remove it and there is nothing left to negotiate with.
-
Peninsula CRE Group also does not represent landlords, work in residential real estate, or provide property management or investment sales.
Owner-user purchases are in scope — a company buying a building to occupy is a client. A company buying to lease out is not.
If you need space in Orange County and want one experienced principal accountable for the outcome, you are exactly who this firm was built for.
Proof From Completed Transactions
Real completed Southern California transactions, anonymized by industry at the client’s request.
-
An engineering company needed highly specific electrical power, HVAC, and operational specs. Searching alone produced little response from listing brokers. Corina ran an extensive search, found a technically qualifying facility, and negotiated directly with the landlord. The result was a long-term lease meeting both office and warehouse needs.
-
A distribution company outgrew its warehouse and needed more loading capacity while staying near its customers and transport routes. Corina evaluated numerous facilities and negotiated flexible terms. The result was a facility supporting future growth with upfront occupancy costs minimized.
-
A retail business needed a highly visible location in a competitive trade area to support expansion. Corina evaluated numerous opportunities and negotiated with multiple landlords. The result was a prime location with favorable lease economics and tenant improvement concessions.
-
A healthcare practice needed space for specialized equipment, efficient patient flow, and future growth with minimal renovation cost. Corina identified multiple medical office options and negotiated terms that reduced build-out costs.
-
A professional services firm faced a significant renewal rent increase and could not tell whether renewing or relocating served them better. Corina ran a market analysis, evaluated competing options, and used relocation alternatives as negotiating leverage. They stayed in their preferred location on favorable renewal terms with reduced occupancy costs.
Cesar Olmedo, a client, put it plainly in his review: he wouldn’t trust anyone else with his commercial real estate needs.
Southern California Doesn’t Stop at the County Line
Plenty of companies searching Orange County should also be looking one county over. Sometimes the right building is in El Segundo, or Carlsbad, or Ontario — and knowing that is exactly what gives you leverage here.

Start Before Your Landlord Does
The tenants who get the best terms in Orange County are not the toughest negotiators. They are the ones who started early enough to have options.
Six to eighteen months before expiration is the window. That is enough time to tour, shortlist, and build a real alternative before your landlord’s offer arrives.
Tell Corina what you need and where. She handles the search and the negotiation personally, start to finish.
