I get this question a lot from investors who are building from the ground up or doing major rehabs: "Do my construction and development hours count toward Real Estate Professional Status?"
Yes. Construction and development are two of the 11 specifically named real property trades or businesses under IRC §469(c)(7)(C). If you're actively involved in building, renovating, or developing real property, those hours absolutely count toward your 750-hour REPS test — and they can be a game-changer for investors who need to stack hours across multiple real estate activities.
I know this firsthand because I track every hour across my own portfolio, which includes new construction projects alongside rental management, acquisitions, and property development. Here's how it works, what the IRS cares about, and how I document it all.
Why New Construction Is a REPS Goldmine
Most investors think of REPS as a landlord strategy — tracking hours managing tenants, coordinating repairs, and handling lease renewals. And for a lot of investors, that's exactly what it is. But the IRS definition of qualifying real property trades is much broader than property management.
Here are the 11 qualifying activities under IRC §469(c)(7)(C):
- Development
- Redevelopment
- Construction
- Reconstruction
- Acquisition
- Conversion
- Rental
- Operation
- Management
- Leasing
- Brokerage
Construction and development are right there at the top. If you're building a new property — whether it's a ground-up new build, a major renovation, or a conversion project — the hours you spend actively managing that construction process are qualifying REPS hours.
And here's the thing about construction projects: they eat hours. In a way that managing a stable, occupied rental property simply doesn't.
What Construction Activities Count (and What Doesn't)
Not every minute you spend thinking about your build counts toward REPS. The IRS draws a clear line between active, managerial participation and passive investor-type activities. Under Treas. Reg. §1.469-5T(f)(2)(ii), investor activities are explicitly excluded from material participation.
Activities That Count
These are the construction and development tasks that qualify for both the 750-hour REPS test and material participation:
Project management and oversight
- Meeting with your general contractor to review progress, timelines, and budgets
- Conducting site visits and walk-throughs to inspect work quality
- Reviewing and approving change orders
- Coordinating between subcontractors (plumber, electrician, HVAC, framing crew)
- Resolving construction issues on-site
Design and planning decisions
- Selecting finishes, materials, fixtures, and layouts — when these are active decisions that affect the build, not passive browsing
- Meeting with interior designers, architects, or engineers about your specific project
- Reviewing blueprints, floor plans, and spec sheets for your build
Permitting and compliance
- Pulling permits and coordinating with the city or county building department
- Meeting with inspectors or scheduling inspections
- Reviewing code requirements and ensuring the build is compliant
Vendor and contractor management
- Sourcing and vetting contractors, getting bids, negotiating contracts
- Reviewing invoices and approving payments
- Managing the construction schedule and holding contractors accountable
- Dealing with delays, material shortages, or quality issues
Financial management of the project
- Tracking construction costs against the budget
- Managing draw schedules with your lender (if using a construction loan)
- Reviewing and processing contractor invoices
- Bookkeeping specific to the construction project
Hands-on work
- Any physical labor you perform on the build — demo, painting, landscaping, installing fixtures
- Supply runs for specific construction materials
- Cleaning or prepping the site
Activities That Don't Count
These fall into the "investor activity" bucket and won't help your REPS claim:
- Browsing Zillow or Redfin looking for your next potential build site (unless you actually acquire the property)
- Analyzing pro formas and running ROI calculations to decide whether to do a deal
- Attending general real estate education seminars or courses
- Reviewing your construction project's financials in a purely passive, non-managerial way
- Time spent arranging financing (calling lenders, comparing loan products) — this is a gray area, but most practitioners treat it as investor activity
The dividing line is simple: if the activity directly affects the construction, operation, or management of a specific property you own, it counts. If it's general analysis, education, or deal-hunting, it doesn't.
How I Track Construction Hours (Real Examples)
I built REPS Time because I needed a system that could handle the reality of how I work — which means logging hours across multiple projects, multiple activity types, and multiple properties in the same day.
Here's what a real construction week looks like in my contemporaneous log:
Monday
- 8:30–11:00am | New Build — Mesa, AZ | Met with GC on-site. Reviewed framing progress on bedrooms 3 and 4. Discussed pool/spa rough plumbing timeline. Approved change order for upgraded electrical panel. (2.5 hrs)
- 1:00–2:30pm | New Build — Mesa, AZ | Selected tile for master bath and pool deck at tile showroom with designer. Compared 4 options, confirmed pricing and lead times. (1.5 hrs)
Wednesday
- 9:00–10:30am | New Build — Mesa, AZ | Drove to property for city inspection (rough plumbing). Met inspector on-site. Discussed one flagged item, coordinated with plumber for correction. (1.5 hrs)
- 11:00am–12:00pm | New Build — Mesa, AZ | Reviewed and approved 3 contractor invoices against draw schedule. Updated construction budget spreadsheet. Called lender to schedule next draw. (1 hr)
Friday
- 8:00–10:00am | Flip — Rainier Ave | On-site walk-through with interior designer. Reviewed cabinet installation progress. Identified issue with countertop template — called fabricator to reschedule. (2 hrs)
- 10:30–11:30am | Flip — Rainier Ave | Met with handyman to scope remaining punch list items: touch-up paint, hardware installation, final cleaning coordination. (1 hr)
That's 9.5 hours in one week from construction alone — and I haven't counted any rental management, tenant communication, or acquisition work from my existing portfolio. Over a full year of active construction, logging 20+ hours per week on the build is completely realistic. That's 1,000+ hours just from construction, well above the 750-hour threshold.
Every entry has five things the IRS needs: date, property, specific task, start time, and end time. No rounding, no vague descriptions, no "construction work — 4 hours." The more specific your entries, the harder they are to challenge. For a deeper dive on documentation standards, see our guide on keeping a contemporaneous log for material participation.
The Critical Timing Rule: Place It in Service
Here's where construction REPS gets nuanced, and where a lot of investors make a costly mistake.
Your construction hours count toward the 750-hour REPS test regardless of whether the property is rented yet. Construction is a qualifying real property trade or business on its own — you don't need to have tenants to log those hours toward REPS.
However, to deduct rental losses using your REPS status, the property must be a rental activity. A property under construction that hasn't been placed in service as a rental isn't generating rental losses yet — it's generating construction costs that get capitalized into the property's basis.
This matters for two reasons:
1. Construction hours count for REPS qualification but not rental material participation until the property is rented.
If your only real estate activity is a new build that won't be rented until next year, you can qualify as a real estate professional this year (the construction hours satisfy the 750-hour and more-than-half tests). But you won't have rental losses to deduct this year because the property isn't in service.
2. The grouping strategy makes this work.
If you own other rental properties alongside your construction project, you can use the grouping election under Treas. Reg. §1.469-9(g) to treat all your rental interests as a single activity. Your construction hours satisfy the REPS test, and your combined rental management hours across your existing properties satisfy material participation for the grouped rental activity. The rental losses from your existing properties become nonpassive.
And when the new build is completed and placed in service, it joins the group — and any cost segregation and depreciation from the new build flows through as nonpassive losses in the year it's placed in service.
In Miller v. Commissioner, the Tax Court specifically allowed a taxpayer to combine construction and rental hours into one real property trade or business. This precedent supports the strategy of stacking construction hours with rental management hours for REPS qualification.
The takeaway: If you're building and you also own rentals, the combination is extremely powerful. The construction project generates massive REPS-qualifying hours, and your rentals generate the losses you need to offset income.
The New Build + Grouping Election Strategy (Step by Step)
This is one of the strongest REPS qualification strategies available, and it's how many investor-developers approach it:
Step 1: Build or heavily renovate a property you own. You're personally involved in the construction — selecting contractors, managing the project, making design decisions, overseeing inspections. You log every hour.
Step 2: Continue managing your existing rental portfolio. Tenant communication, maintenance coordination, lease renewals, bookkeeping — the standard rental management work. Log those hours separately, tagged to each rental property.
Step 3: File the grouping election. Attach a statement to your tax return electing to treat all rental real estate interests as a single activity under Treas. Reg. §1.469-9(g). This groups your existing rentals (and, once placed in service, the new build) into one activity for material participation purposes.
Step 4: Qualify for REPS using combined hours. Your construction hours + rental management hours + any other real property trade hours all flow into the 750-hour REPS test. If you pass 750 hours and more than half your total working time is in real estate, you qualify.
Step 5: Prove material participation on the grouped rental activity. Using the seven material participation tests, demonstrate that you (and/or your spouse) materially participated in the grouped rental activity. With existing rentals in the group, the rental management hours typically carry this.
Step 6: Deduct rental losses against active income. Your grouped rental losses — from depreciation, mortgage interest, operating expenses, and eventually cost segregation on the new build — flow through as nonpassive losses on your joint return.
What to Track During Each Phase of a New Build
The documentation requirements shift as your project moves through phases. Here's what to log at each stage:
Pre-Construction
- Meeting with architects, engineers, designers about project scope
- Permit applications and building department coordination
- Contractor sourcing: getting bids, interviewing GCs, checking references
- Lot preparation and site work you oversee
- Design selections that require active decisions
Active Construction
- Every site visit with purpose, duration, and what you reviewed or decided
- Contractor meetings — who attended, what was discussed, decisions made
- Inspection coordination and attendance
- Change order review and approval
- Budget tracking and draw schedule management
- Material selection and purchasing
- Quality control walk-throughs
- Problem resolution (delays, defects, weather issues, permit holds)
Completion and Lease-Up
- Final walk-through and punch list creation
- Certificate of occupancy coordination
- Furnishing and staging (if it's a short-term rental — see our STR tax loophole guide)
- Listing creation, photography coordination, marketing
- Tenant screening, lease execution, move-in coordination
Every one of these tasks should be logged in your contemporaneous log with the date, property address, specific activity, and time spent. Your log should tell the complete story of your involvement — from dirt to tenants.
How Construction Hours Stack With Your Other Real Estate Activities
One of the most misunderstood aspects of REPS is that you don't need all 750 hours to come from a single activity. The 750-hour test draws from ALL real property trades or businesses in which you materially participate.
That means if you have:
- 400 hours on your new build (construction)
- 250 hours managing your 4 existing rentals (rental operation and management)
- 150 hours on a flip project (reconstruction)
That's 800 total REPS-qualifying hours. You pass the 750-hour test, and you pass it comfortably.
This stacking effect is why investors who do construction or development alongside rental ownership find REPS dramatically easier to qualify for than a passive landlord with 3 stable rentals and a property manager. For a complete breakdown of how to prove your hours for each activity type, see our guide on tracking hours as a real estate agent or investor.
And here's the real power play: combine this with the spouse strategy. If one spouse manages the construction project while the other earns a high W-2 income, the construction-managing spouse qualifies for REPS, and the couple's rental losses offset the W-2 income on their joint return. Read our stay-at-home parent REPS roadmap for the complete spouse strategy.
Common Mistakes With Construction REPS Claims
Logging contractor hours as your own. Your GC spent 40 hours on-site this week. You were there for 6 of those hours overseeing the work. You log 6 hours, not 40. The IRS is very clear: material participation is based on YOUR personal involvement. And if you're using material participation Test 3 (100 hours and more than anyone else), you need to know how many hours your contractors are logging too.
Vague entries like "construction work." In Penley v. Commissioner (T.C. Memo 2017-65), the Tax Court rejected vague, rounded entries. Your log should say "Met with plumber on-site to review rough-in layout for master bath, identified conflict with HVAC ductwork, coordinated solution with HVAC sub" — not "plumbing stuff, 2 hours."
Not tracking before you break ground. Pre-construction planning, design, permitting, and contractor selection all count. I've seen investors lose hundreds of hours because they didn't start logging until the foundation was poured. Start tracking the day you begin making active decisions on the project.
Forgetting the place-in-service requirement. If you're counting on the new build's depreciation losses for the current tax year, the property must be placed in service (available for rent or actually rented) before December 31. If your build runs into January, those losses push to next year. Plan your construction timeline with tax year deadlines in mind.
Not separating personal use. If you plan to use the property personally at all — even for a weekend to "test" the Airbnb setup — be careful. Under IRC §280A(d)(1), personal use exceeding 14 days or 10% of rental days (whichever is greater) reclassifies the property as a personal residence with limited deductions.
