Retail Space for Sale: How to Buy a Retail Building or Strip Center in Northern California

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

When you buy a retail building or strip center, you are buying two things: the real estate and its leases. Confirm that the city or county zoning allows each current and planned retail use, verify every lease against a tenant estoppel certificate, and find out whether the property has had a CASp accessibility inspection before you remove contingencies. Then line up financing that fits how the building will be used: an owner-user storefront can qualify for SBA loans, a fully leased investment center generally cannot.

This guide covers those steps for retail property in the counties we serve, from Sonoma, Napa and Marin to the East Bay, the South Bay, Sacramento and the Sierra foothills. It gives rules and process, not prices, cap rates or market forecasts.

What counts as retail property

Retail property ranges from a single storefront on a downtown main street to a multi-tenant strip center with a shared parking lot, a pad building leased to one user, or the ground floor of a mixed-use building with apartments above. Wine country adds its own variant, the tasting room, which mixes retail with alcohol licensing. Each type raises the same core questions about zoning, leases, access and financing, but in different proportions: a single-tenant pad is mostly a lease-credit question, while an older strip center is often a building-condition and accessibility question.

Step 1: Confirm zoning for each retail use

California leaves zoning to cities and counties. Government Code section 65850 lets a city or county legislative body regulate how buildings and land are used for business and other purposes, along with building size and height, signs, setbacks and off-street parking and loading. That means the rules for a storefront in Santa Rosa come from the City of Santa Rosa, while a crossroads store outside city limits in Sonoma County answers to the county. Many unincorporated parcels carry a city mailing address, so confirm the jurisdiction by assessor’s parcel number.

What to check with the planning department:

• Permitted vs. conditional uses. Retail zones usually list some uses as allowed by right and others as requiring a conditional use permit. Under Government Code section 65901, a zoning administrator or board of zoning adjustment hears conditional use and variance applications where the local ordinance provides for them. Restaurants, bars, alcohol sales, gyms, drive-throughs and late-night hours are common examples that local codes treat separately from general retail; read your jurisdiction’s use table rather than assuming.
• Existing permits and conditions. Ask for any use permit on file. Conditions of approval (hours, parking, signage, outdoor seating) can run with the land.
• Nonconforming status. If a current use or the building itself no longer fits the zoning, ask how the local code treats a change of tenant, expansion or rebuild after damage.
• Parking. Government Code section 65863.2 generally bars a public agency from imposing minimum automobile parking requirements on residential, commercial or other development within one-half mile of a major transit stop. Hotels and other transient lodging are excluded, event centers must still provide worker parking, and accessible and EV-charging space requirements still apply. For a retail buyer, this can matter when a new tenant’s use would otherwise need more spaces than the lot has; confirm with the planning department whether the parcel qualifies.
• Signs. Sign rules are part of local zoning under section 65850; a new tenant’s signage may need a separate permit.

A written zoning verification letter from the city or county is the cleanest record. Our commercial due diligence checklist lists the permit-history and code-violation records to request at the same time.

Step 2: Read the leases and get tenant estoppels

In a leased retail building, the leases are most of the value. Read each lease and every amendment, and look for:

• Expense structure. Is it a triple-net (NNN), modified gross or full-service lease? Who pays property tax, insurance, common area maintenance (CAM) and roof and parking-lot replacement? Our guides to commercial lease types and buying NNN-leased property cover the differences.
• Property tax pass-throughs. A purchase is a change in ownership. The Board of Equalization’s change in ownership FAQ explains that under Proposition 13 the assessor reassesses the property to its current market value as of the date ownership changed. Whether tenants share that increase depends on each lease’s tax clause, so read it before you underwrite expenses.
• Retail-specific clauses. Exclusive-use rights (one tenant’s right to be the only seller of a category), co-tenancy clauses (rent relief if an anchor leaves), radius restrictions, percentage rent, and options to renew, expand or purchase.
• Assignment and SNDA terms. Whether the lease will subordinate to your new loan.

Then confirm the leases with tenant estoppel certificates, signed statements from each tenant on rent, term, deposits, defaults and side agreements. Our estoppel certificate guide explains what to ask for and when to send them.

Security deposits. For commercial tenants, Civil Code section 1950.7 requires a landlord whose interest ends through a sale either to transfer the deposits, less lawful deductions, to the successor and notify each tenant by personal delivery or certified mail, or to refund them. A buyer who receives deposits takes on the landlord’s obligations for them. Reconcile the rent roll, estoppels and deposit credits in escrow.

Step 3: Check CASp and accessibility status

Retail buildings are open to the public, so accessibility deserves early attention. Civil Code section 1938 requires the owner or lessor of commercial property to state on every lease signed on or after January 1, 2017, whether the premises have been inspected by a Certified Access Specialist (CASp). If there is a CASp report, the tenant must get it at least 48 hours before signing or may rescind within 72 hours after signing, and repairs of violations it notes are presumed to be the owner’s responsibility unless the parties agree otherwise. If no disability access inspection certificate has been issued, the lease must include a statutory statement that a CASp inspection is available on the tenant’s request.

For a buyer, that means two things: ask the seller for any CASp report and confirm that each existing lease contains the required statement. Parking lots, path of travel from the sidewalk, entrances, counters and restrooms are common review areas. See our full CASp and ADA guide for commercial property.

Step 4: Environmental and building condition

Former dry cleaners, auto service bays and fuel stations often sit inside or next to retail centers. Order a Phase I environmental site assessment early; our Phase I ESA guide explains the standard, the state database lookups and when a Phase II follows. California also requires the owner of nonresidential property who knows, or has reasonable cause to believe, that a hazardous substance release is on or under the property to give written notice to a buyer or tenant before the sale or lease, under Health and Safety Code section 78700.

Older main-street buildings raise a seismic question. Under Government Code section 8875.8, the owner of an unreinforced masonry (URM) building in seismic zone 4 who has notice of its construction type must post a warning sign at the entrance; a sign on the door is a reason to ask about retrofit history and any local URM ordinance. For roofs, HVAC, parking-lot paving and fire systems, commission a property condition assessment and compare it with the lease repair clauses.

Step 5: Financing a retail purchase

How the building will be used drives the loan options.

Our SBA 504 vs. 7(a) comparison explains how the two programs differ. Investment buyers typically use conventional bank, credit union, life company or CMBS loans; in practice those lenders underwrite the rent roll, lease terms and tenant credit, so the estoppels and lease abstracts from Step 2 become loan documents too. If you are trading out of another property, review the 1031 exchange identification deadlines before you go under contract.

Step 6: Value it on income, not just comparable sales

Leased retail is valued mostly on its income. Start with net operating income built from actual leases (not the seller’s pro forma), then test lease rollover, vacancy and any CAM reconciliation shortfalls. Our commercial property valuation guide walks through the income, sales comparison and cost approaches.

Questions people ask

Do I need a use permit to open a store in a retail building?

It depends on the zone and the use. Many local codes allow general retail by right in commercial zones but require a conditional use permit for uses such as restaurants, alcohol sales or drive-throughs. Under Government Code section 65901, those applications go to the local zoning administrator or zoning board where the ordinance provides for them. Ask the planning department for the parcel’s use table.

Does California require a CASp inspection before I buy a retail building?

No. Civil Code section 1938 requires disclosure on leases of whether the premises were CASp-inspected, and its statutory statement says state law does not require an inspection. Many buyers still order one because retail property serves the public.

What is an estoppel certificate and why does my lender want it?

It is each tenant’s signed confirmation of the lease terms, rent, deposits and any defaults. Lenders and buyers rely on it to confirm the rent roll. See our estoppel guide.

Will my property tax go up after I buy a strip center?

The purchase is a change in ownership, and under Proposition 13 the assessor reassesses to current market value as of the transfer date, per the BOE. Whether tenants reimburse the increase depends on each lease.

Can I use an SBA loan to buy a retail building I will lease out?

Not if it is a passive investment. SBA’s rules make passive landlord businesses ineligible, but an owner-user who occupies at least 51% of an existing building can qualify.

What happens to tenants’ security deposits when I buy?

Under Civil Code section 1950.7, the seller either transfers commercial deposits to you, with notice to each tenant, or refunds them. If you receive them, you take on the landlord’s obligations for them.

Do parking minimums still apply to my retail property?

Possibly not. Government Code section 65863.2 generally bars minimum parking requirements for projects within one-half mile of a major transit stop, with exceptions. Ask the city or county whether your parcel qualifies.
