House Hacking with Euclid St. Paul Alley Apartments

What if your next St. Pete home helped pay its own mortgage? In Euclid St. Paul, many properties sit on alleys and some already have garage or over-garage spaces, which makes house hacking with an alley apartment a smart, local fit. You want clear steps, real numbers, and the rules that matter so you can move with confidence. In this guide, you’ll learn how alley apartments work in St. Petersburg, what it costs, what you can rent for, and how to finance it. Let’s dive in.

Why Euclid St. Paul fits alley ADUs

Euclid Place, also called Euclid St. Paul, is an established neighborhood just north of downtown with a historic mix of bungalows and small multifamily homes. Alleys are part of the original neighborhood fabric, and garage apartments are not unusual. That context makes a detached or above-garage accessory dwelling unit feel right at home here. You can read more about the neighborhood’s history on the Euclid St. Paul page on Wikipedia.

What St. Pete allows today

St. Petersburg expanded where accessory dwelling units are allowed, and the city provides a GIS tool to check parcel eligibility. Use the city’s ADU resources referenced in this public update to confirm your lot.

• Size: ADUs are commonly limited to 800 square feet or 67% of the primary home, whichever is smaller. Detached, attached, and over-garage forms are typically allowed, subject to zoning. See a concise summary of common standards from this local ADU resource: ADU Design Builders eligibility overview.
• Parking: Expect to provide one off-street space for the ADU unless an exemption applies. Always verify your exact zoning requirements.
• Short-term rentals: Many residential zones restrict stays under 30 days. If your goal is house hacking with a long-term lease, you are usually in safer territory. Check the county’s definition and program here: Pinellas County STR overview.

How to check your lot

• Look up your address in the City’s ADU GIS and read the city guidance noted in this press resource.
• Confirm zoning, lot size, alley access, and parking.
• If needed, email planning staff to verify eligibility before you design plans.

Expected rent and payoff math

Recent listings suggest one-bedroom rentals in Euclid St. Paul often fall in the low-to-mid $1,400s up to $1,800+, depending on condition and location. Scan current neighborhood listings on Zumper’s Euclid Place page to set expectations. When estimating your offset, subtract vacancy, maintenance, utilities, and any management costs from projected rent.

Financing with ADU income

Lenders increasingly recognize ADU income. FHA updated policy so a portion of ADU rent can help you qualify, with documentation rules that your lender will explain. Review the FHA announcement here: HUD ADU income policy. Conventional options are evolving too. Fannie Mae details how accessory-unit income may be used under certain programs and appraisals: Fannie Mae ADU policy.

Permitting steps in St. Pete

• Confirm eligibility. Start with the city’s ADU GIS and guidance linked above.
• Prepare plans. Hire a designer or architect to meet Florida Building Code, setbacks, lot coverage, and ADU size limits.
• Submit for permits. Use the city’s ePlan process and be ready to document parking, utility connections, and alley access for trash service if required.
• Check flood data. Look up your FEMA zone and elevation needs on Pinellas County flood maps. Flood requirements can affect design and cost.

Design and construction tips

Converting an existing garage or finishing space above a garage is often the most budget-friendly path because you reuse structure and utilities. Plan for safe egress, fire separation above a garage, proper stairs, and HVAC. Utility capacity and metering vary by jurisdiction, so confirm what is allowed before you bid.

• Cost benchmarks: Industry guides commonly show $60,000 to $300,000+ total, or roughly $100 to $400+ per square foot, depending on scope, finishes, and site work. See ranges here: HomeGuide ADU cost.
• Build in a contingency: A 10% to 20% buffer for surprises is wise, especially if your property has flood or structural needs.

Long-term vs short-term rentals

For most Euclid homeowners, long-term leasing is the cleanest way to house hack with an ADU. St. Petersburg and Pinellas County define and regulate short-term rentals separately and restrict them in many residential zones. Start with the county’s guidance to understand what counts as a short-term rental and how registration works: Pinellas County STR overview.

Landlord basics in Florida

When you rent an ADU, you become a landlord. Florida’s Chapter 83 covers deposits, notices, and eviction procedures. Read the statute text here: Florida Statutes, Chapter 83. Also plan for tax reporting on rental income and talk to your insurance provider about coverage updates.

House-hacking playbooks that work

• Live in the main home, rent the ADU to one tenant on a long-term lease.
• Live in the ADU and rent the main home, if your layout and financing allow it.
• Convert an existing garage or second-floor space over a garage into a code-compliant one-bedroom.

Resale and documentation

A permitted, code-compliant ADU can add day-to-day utility and appeal to future buyers who value flexibility. Keep copies of plans, permits, inspections, and any appraisals that document the ADU and market rent. Strong records support value at resale and make underwriting easier for the next buyer.

Your next steps

• Verify ADU eligibility for your specific Euclid lot.
• Pull rent comps and sketch a conservative budget with contingency.
• Consult an ADU-savvy lender about using rental income.
• Get bids from licensed contractors who know St. Pete’s process.
• Plan for long-term leasing to keep compliance straightforward.
