Commercial Loans in Boca Raton, FL: Downtown Rules, Taxes and What Lenders Check

Short answer

A Boca Raton commercial loan is sized on the building's net operating income and value, and the local items that move the numbers are a 16.9090-mill tax rate for a city address, a reset to market value the year after you buy, and downtown rules that cap height at 100 feet and set parking per square foot. Commercial and multifamily (5+ units) loans are business-purpose loans, subject to credit approval and property review.

The basics, and what is local in Boca

How lenders use net operating income (NOI), debt service coverage and loan-to-value is in our Florida commercial loan guide. In short: the loan is the smaller of what the income can carry and what the value supports.

Boca Raton adds four things that reach the term sheet: the tax rate and the reset after a sale, the downtown ordinance if the parcel is in the downtown district, city and county business tax receipts, and flood risk in the eastern part of the city.

Property types we see most: medical and professional office, retail and restaurant space along the main corridors, mixed-use downtown, small industrial and flex space, and apartment buildings. Five or more units is a commercial loan even with no storefront; see multifamily loans.

These are business-purpose loans. Federal Regulation Z (12 CFR 1026.3) exempts credit made primarily for a business or commercial purpose, so you get a term sheet and commitment letter instead of a consumer Loan Estimate. Read the prepayment terms, balloon date and personal guarantee closely.

Downtown Boca: the 100-foot cap and parking rules

Downtown parcels fall under Ordinance 4035 and the Downtown Rules, the Boca Raton Downtown Development of Regional Impact covering about 344.4 acres. Per the city's amended text, as of November 2026:

• Height: no part of a building may exceed nine stories or 100 feet, with exceptions only for projects approved under the Downtown Quality Development Regulations. Nonresidential buildings also cannot be taller than their distance to the nearest home outside the downtown district.
• Parking minimums: office 3 spaces per 1,000 sq ft, retail 4 per 1,000 sq ft, residential 1.75 per unit, and restaurants 1 per 38.9 sq ft of gross floor area plus 1 per 2.2 linear feet of bar. Shared parking can cut the total by up to 25% unless a larger technical deviation is approved.

Why a lender cares: parking drives which tenants can legally use a building. Turning office or retail space into a restaurant can need far more spaces than the site has. If your plan changes the use, confirm parking and zoning before you sign, and consider a bridge loan to buy and reposition, with a long-term loan once the new use is approved and leased.

The city has been working on an update to the downtown rules. If your plan depends on height, density or use, ask the city which rules apply to your parcel at closing.

Property taxes: 16.9090 mills and the reset

Taxes sit inside the NOI. The Palm Beach County Property Appraiser's 2026 proposed rates for a Boca Raton city address total 16.9090 mills, about 1.69% of taxable value, as of November 2026. That includes the city's 3.6476 operating plus 0.0163 debt, the county's 4.5000 plus 0.0210 debt, the school board's 6.2870, and the Greater Boca Raton Beach and Park District's 1.0331. The city's own brochure shows the same total.

• Reset when you buy. Under Florida Statutes 193.1555, non-residential property is reassessed at just value on January 1 after a change of ownership or control. Apartment buildings of 9 or fewer units reset the same way under 193.1554.
• Buying the LLC counts. A cumulative transfer of more than 50% of the owning entity is a change of control.
• 10% cap after that on non-school levies. School levies are not capped.
• Big renovations reset it. An improvement that raises just value by at least 25% puts the property back at just value.

Lenders underwrite taxes on your price, not the seller's bill. If the seller has owned for years, the jump can be large.

Business tax receipts and flood risk

Business tax receipt and Certificate of Use. Boca Raton requires a business tax receipt and Certificate of Use for each business location, and staff check that the use fits the zoning. Receipts run October 1 to September 30; renewal opens July 1 and late renewals pay penalties. Every business must also get a Palm Beach County receipt, after city approval. Per the city, as of November 2026, a new application may include:

• $30 application fee, $105 business tax receipt and $50 Certificate of Use zoning review.
• $45 each for code, fire and utility inspections, plus other fees that may apply.

Ask your tenants for current receipts during due diligence; a use that cannot get a Certificate of Use is a vacancy risk. City Hall: 561-393-7700.

Flood. The city says a large portion of Boca Raton lies in the special flood hazard area, and FEMA adopted new flood maps on December 20, 2024. Check the parcel on FEMA's map; the city's floodplain manager keeps elevation certificates for new or substantially improved buildings. The NFIP covers up to $500,000 for a commercial building and $500,000 for contents, so larger buildings often need excess coverage. Put a real flood and wind quote in the NOI; see what a flood zone means for your loan.

Example only: a $3,000,000 Boca Raton building

Example only, not a quote or an approval. An investor buys a medical office building in Boca Raton for $3,000,000. The rent roll shows NOI of $210,000 a year after vacancy, taxes on the new price, insurance and expenses. Assume a lender with a 1.25 minimum DSCR and a 70% maximum LTV; each lender sets its own limits by property type.

• Income test: $210,000 / 1.25 = $168,000 a year, the most annual principal and interest the building can carry. The lender turns that into a loan amount using that day's rate and amortization. Rates vary daily; call for today's pricing.
• Value test: 70% of $3,000,000 = $2,100,000.
• The loan is the lower of the two. If the income test supports $2,000,000, that is the loan, and the down payment is $1,000,000.

Taxes on the new price: at 16.9090 mills, about $50,730 a year. Florida closing taxes on a $2,000,000 loan, as of November 2026:

• Deed stamps: $0.70 per $100 of price outside Miami-Dade = $21,000. The contract sets who pays.
• Note stamps: $0.35 per $100 = $7,000.
• Intangible tax: 2 mills on the loan = $4,000.

How we shop a Boca Raton commercial loan

Commercial lenders pick property types, so the first step is matching yours. Then we:

• Rebuild the NOI with taxes on your price, real wind and flood quotes and current leases.
• Check downtown rules, parking and the Certificate of Use early, so the appraisal and lender review move together.
• Compare term sheets side by side: conventional commercial, DSCR for small mixed-use, hard money in Boca Raton for a fast close, and bridge when the building needs work or lease-up first.
