A construction loan is a short-term financing product that funds the cost of building or substantially rebuilding a property, with funds disbursed in stages as work is completed rather than in a lump sum at closing. In Philadelphia, construction loans are used by homeowners building on vacant lots in transitional neighborhoods like Kensington, Grays Ferry, and North Philadelphia, by developers doing teardown-rebuilds in gentrifying corridors, and by investors executing full gut-to-stud rehabilitation projects on distressed rowhouses that conventional renovation loans cannot underwrite.
Philadelphia's rowhouse density, infill lot constraints, zoning complexity, and the L&I permit process create a specific set of risks and requirements that distinguish construction lending in the city from suburban or rural new construction. This guide covers how construction loans work, the one-close versus two-close structure decision, how draws are managed, builder qualification requirements, lot loans, Philadelphia zoning and permit considerations, the 10-year tax abatement, and what to expect across the full construction-to-permanent financing arc.
How construction loans work
A construction loan is a short-term credit facility -- typically 12 to 18 months -- that covers the cost of construction. Unlike a standard mortgage, which disburses the full loan amount at closing and is secured by an existing property, a construction loan holds funds in reserve and releases them in draws as construction milestones are verified by an independent inspector hired by the lender. The borrower pays interest only on the drawn balance during construction, not on the full approved loan amount. This means interest charges start low and increase as more funds are drawn.
At project completion, when the Philadelphia Department of Licenses and Inspections issues a Certificate of Occupancy confirming the structure is habitable and code-compliant, the construction loan either converts to a permanent mortgage (in a one-close structure) or is paid off by a separate permanent mortgage (in a two-close structure). The permanent mortgage is a standard 15- or 30-year amortizing loan secured by the completed property.
What construction loans cover
Construction loan proceeds can fund land acquisition (if the lot is purchased simultaneously with the construction loan), site preparation and demolition, foundation work, framing, roofing, rough mechanical work (plumbing, HVAC, electrical), insulation and drywall, finish carpentry, fixtures and appliances, exterior work and landscaping, and soft costs including architectural and engineering fees, permit fees, and builder overhead. Lender-specific policies vary on which soft costs are fundable; confirm in advance what your lender will and will not advance.
One-close versus two-close construction loans
The fundamental structure decision in construction financing is whether to use a one-close (construction-to-permanent) loan or a two-close (separate construction and permanent) approach. Each has distinct advantages and the right choice depends on your rate environment, timeline, and risk tolerance.
| Feature | One-Close (C2P) | Two-Close |
|---|---|---|
| Number of closings | One, at construction start | Two: construction + permanent |
| Closing costs paid | Once | Twice ($8,000-$18,000 additional) |
| Rate lock | Locked at construction closing | Floats until permanent close |
| Rate risk | Rate locked before construction; may miss rate drops | Full market risk during 12-18 month build |
| Permanent lender flexibility | Predetermined; limited to original lender terms | Shop permanent market at completion |
| Qualification timing | Qualify once, before construction | Must re-qualify at permanent closing |
| Best for | Rising rate environments; preference for certainty | Falling rate environments; strong post-completion credit |
In Philadelphia's current rate environment, most owner-occupied borrowers prefer the one-close structure to lock their permanent rate and avoid a second set of closing costs. Investors and spec builders more frequently use two-close structures or short-term construction financing -- including hard money -- because they plan to sell or refinance into a portfolio or DSCR loan rather than a standard permanent mortgage.
FHA and VA one-close construction loans: FHA offers a one-time-close construction-to-permanent loan with a 3.5% down payment for eligible borrowers, making it the lowest-barrier path to new construction financing. VA also offers a one-time-close construction loan for eligible veterans with no down payment requirement. Both programs apply the same property condition standards (minimum property requirements) at the appraisal stage and require full L&I permit compliance at close. These programs have stricter builder approval requirements than conventional construction loans and typically have longer processing timelines.
Down payment and LTV requirements
Construction loan LTV is calculated on the lesser of the total project cost (land plus construction budget) or the completed appraised value (the as-completed value estimated by the appraisal). Most conventional construction lenders allow 80% LTV on owner-occupied builds, requiring 20% down on the total project cost. FHA one-close allows up to 96.5% LTV. Investor and spec construction loans typically require 70% to 75% LTV, meaning 25% to 30% of the total project cost must come from the borrower.
Land equity as down payment
If you already own the lot where you plan to build, the equity in that land can substitute for all or part of the cash down payment. A lender will order an appraisal of the land at construction-loan application. If the land appraises at $150,000 and the total project cost (land plus construction) is $600,000, the land represents 25% of the project cost -- meeting a 25% down payment requirement without additional cash. Confirm with your lender how they calculate land equity credit; some discount the land value if it was purchased more than 12 months ago or if the appraisal reflects speculative upside rather than current market.
How construction draws work
Construction funds are held in a controlled account by the lender and released in stages as construction milestones are completed. The draw process is designed to protect both the borrower and the lender: it ensures the lender's collateral (the partially built structure) stays ahead of the loan balance, and it gives the borrower a structured payment mechanism that ties funding to verified progress.
Typical Philadelphia construction draw schedule
| Draw | Milestone | Typical % of Budget Released |
|---|---|---|
| Draw 1 | Site prep, demolition, foundation complete and inspected by L&I | 15-20% |
| Draw 2 | Framing complete, roof deck installed, rough mechanical (plumbing, HVAC, electrical) roughed in | 20-25% |
| Draw 3 | Rough mechanical inspections passed by L&I; insulation installed | 15-20% |
| Draw 4 | Drywall hung and taped; exterior complete (windows, doors, siding or masonry) | 15-20% |
| Draw 5 | Finish work: flooring, trim, cabinetry, fixtures, paint; mechanical trim-out | 15-20% |
| Final Draw | Certificate of Occupancy issued; punch list complete; title bring-down clean | 5-10% |
Before each draw is released, the lender sends an independent inspector (a construction monitor or bank inspector, not a home inspector) to verify the work claimed in the draw request has been completed. The inspection report comes back to the lender within 2 to 5 business days; the lender then reviews and releases funds, typically within 3 to 7 business days of the inspection. Builders who are accustomed to progress billing need to account for this 1 to 2 week delay between completing work and receiving payment. Budget for carrying costs during the draw delay period.
Retainage
Most construction lenders hold back 5% to 10% of each draw as retainage -- funds withheld until the final Certificate of Occupancy is issued and all lien waivers are received from subcontractors. Retainage protects the lender against mechanics liens filed by unpaid subcontractors after the work is done. See our Philadelphia mechanics lien guide for how lien exposure works in Pennsylvania and why unconditional lien waivers are required at each draw before retainage is released.
Builder and contractor qualification
Construction lenders do not just underwrite the borrower -- they underwrite the builder. An approved builder is typically required for all construction loans, and lenders have their own approval processes that differ by institution. The builder approval process is designed to confirm the contractor has the experience, licensure, bonding, and financial capacity to complete the project.
What Philadelphia lenders typically require from builders
- Pennsylvania Home Improvement Contractor (HIC) registration (mandatory for residential work over $500) and Philadelphia contractor license via eCLIPSE
- General Liability insurance ($1 million per occurrence minimum, $2 million aggregate) with the lender named as additional insured
- Workers' Compensation insurance covering all employees and subcontractors
- Builder's Risk (course of construction) insurance covering the project value during build
- 2 to 3 references from prior completed projects of similar scope
- Photos of 1 to 3 comparable completed projects
- Detailed construction budget with line-item breakdown (lenders compare to cost databases like RSMeans to flag underestimates)
- Construction timeline with milestone dates
- Resume or company history demonstrating experience with comparable projects
First-time builders or owner-builders (where the borrower acts as their own general contractor) face significantly higher qualification hurdles and are declined by most conventional construction lenders. If you plan to manage the project yourself, expect to hire a licensed GC as the prime contractor of record, even if you are doing substantial work yourself.
Check the permit history on any Philadelphia address
Flagstone pulls L&I permit records, open violations, and OPA ownership data in seconds -- essential due diligence before buying a lot or planning a new construction project.

If you want to purchase a lot now and build later, you will need a lot loan (also called a land loan) to finance the land acquisition while you finalize plans, secure permits, and arrange construction financing. Lot loans are a distinct product from construction loans and carry different terms.
Lot loan characteristics
| Feature | Improved Lot (utilities at lot line) | Unimproved Lot (no utilities) |
|---|---|---|
| Maximum LTV | 70-80% | 50-65% |
| Down payment | 20-30% | 35-50% |
| Interest rate premium over 30yr fixed | +1.5% to +3% | +2% to +4% |
| Typical term | 5-15 years (balloon or amortizing) | 2-5 years (balloon) |
| Lender type | Community banks, credit unions, some portfolio lenders | Primarily community banks and credit unions |
In Philadelphia, most residential vacant lots are improved lots -- city water and sewer are at the street, gas and electric are available. This makes Philadelphia lot loans somewhat more accessible than rural land loans. However, lenders still want to confirm buildability: that the lot is properly zoned for the intended use, that it meets minimum lot size requirements, that there are no title issues or encumbrances, and that there are no environmental conditions (Phase I ESA) that would complicate development.
Philadelphia-specific construction considerations
Zoning for new construction
New construction in Philadelphia requires that the project comply with the Philadelphia Zoning Code. For a standard rowhouse infill on a vacant lot in an established residential block, the most likely zoning classification is RSA-5 (Residential Single-Family Attached), which permits attached rowhouses by right -- no variance required if the design meets dimensional standards for lot width, setbacks, building height, and impervious coverage. However, if the lot is wider than the RSA-5 standard or adjacent to mixed-use or commercial zoning, review the zoning classification on the Philadelphia Atlas before assuming by-right approval.
Projects that need a zoning variance -- including builds that exceed height limits, have reduced setbacks, or plan density above what the base zoning allows -- must go through the Zoning Board of Adjustment (ZBA). ZBA hearings require community notification through the Registered Community Organization (RCO) for the neighborhood, a public hearing, and a waiting period. Budget 3 to 6 months for a contested ZBA variance and confirm your construction lender's tolerance for pre-permit variances. See our Philadelphia zoning variance guide for the full variance process.
L&I permits for new construction
A Philadelphia building permit from the Department of Licenses and Inspections is required for all new construction. The permit application for a new residential structure requires: approved architectural drawings showing all elevations, floor plans, and sections; structural drawings stamped by a licensed Pennsylvania structural or civil engineer; a zoning compliance certification from the Zoning Division (or approved ZBA variance); contractor license documentation in eCLIPSE; and applicable permit fees. L&I new construction permit processing currently takes 6 to 16 weeks for standard residential projects from complete application submission to permit issuance, with complex or non-conforming projects taking longer.
Most construction lenders require a fully approved and issued building permit before the construction loan closes and funds. This means you need to complete the design, engineering, and permit process -- spending $15,000 to $40,000 in soft costs -- before you have construction financing in hand. Some lenders will approve but not fund the loan before permits are issued, allowing you to lock the loan and move through the permit process with loan approval in place.
Party wall obligations for rowhouse infill
Philadelphia rowhouse infill on a lot flanked by existing structures creates party wall obligations that affect design, construction sequencing, and insurance. A party wall is a shared wall between two adjacent buildings. If you are building a new rowhouse adjacent to an existing structure, you have an obligation not to damage or destabilize the neighbor's party wall during construction. This requires: a pre-construction survey of the party wall condition (typically a licensed engineer documents the existing condition with photographs), vibration monitoring during foundation excavation, temporary shoring as needed, and repair of any damage caused during construction. Budget $5,000 to $15,000 for party wall engineering and monitoring on a standard infill rowhouse build. See our Philadelphia party wall guide for full legal obligations and documentation requirements.
Philadelphia 10-year tax abatement for new construction
New residential construction in Philadelphia is eligible for the 10-year property tax abatement, which exempts the assessed value of the improvement (the structure) from property taxes for 10 years after the Certificate of Occupancy is issued. During the abatement period, the property owner pays taxes only on the land value, not the building value. For a newly constructed rowhouse with a finished value of $500,000 on a lot assessed at $80,000, the abatement saves approximately $8,000 to $12,000 per year in property taxes compared to full assessment.
The abatement significantly improves the economics of new construction in Philadelphia relative to comparable suburban markets with no abatement. Lenders underwriting the permanent mortgage at construction completion must use the actual PITI (principal, interest, taxes, insurance) including the abated -- not full assessed -- tax amount for DTI calculation during the abatement period. Confirm your permanent lender's policy on tax abatement and how they calculate DTI for abated properties. See our Philadelphia 10-year tax abatement guide for full abatement eligibility, application, and expiration planning.
Transfer tax on lot acquisition
If you purchase a vacant lot as part of your construction project, Philadelphia's 4.278% combined transfer tax applies to the lot purchase price. On a $150,000 vacant lot in North Philadelphia, transfer tax is approximately $6,400 -- a material soft cost to include in your project budget. The transfer tax does not apply again at construction completion unless you sell the property. See our Philadelphia transfer tax guide for full rate breakdown, exemptions, and negotiation conventions.
Construction loan rates and costs
Construction loans carry higher interest rates than permanent mortgages, reflecting the lender's higher risk during the construction phase when the collateral is incomplete and the borrower's ability to complete the project is unproven. Rates vary by lender type, borrower strength, loan-to-cost ratio, and prevailing market conditions.
| Lender Type | Typical Construction Rate (2026) | Origination Points | Owner-Occupied Max LTC | Investor Max LTC |
|---|---|---|---|---|
| Community bank / credit union (C2P) | 7.5% - 9.0% | 0 - 1 point | 80-85% | 70-75% |
| National bank (C2P program) | 7.75% - 9.25% | 0.5 - 1.5 points | 80% | N/A (many decline investors) |
| FHA one-time-close | 7.25% - 8.5% (fixed permanent rate) | 0 - 1 point | 96.5% | Not available |
| Portfolio lender / hard money | 10% - 13% | 2 - 4 points | N/A | 65-75% of ARV |
LTC (loan-to-cost) is how construction lenders express their limit -- the percentage of the total project cost they will fund. A $600,000 project with an 80% LTC means the lender will fund $480,000 and the borrower must contribute $120,000. Construction loan interest accrues only on the drawn balance, so the average outstanding balance during a 12-month build is typically 50% to 65% of the approved loan amount -- lowering effective carry cost relative to the maximum approved amount.
Comparison: construction loan options for Philadelphia builders and investors
| Factor | One-Close C2P (Conventional) | Two-Close (Construction + Permanent) | Hard Money / Private Construction |
|---|---|---|---|
| Best use case | Owner-occupied new builds with plan certainty | Investors expecting to shop permanent market | Spec builds, distressed lots, fast-close situations |
| Closing costs | One set ($8,000-$15,000) | Two sets ($16,000-$30,000+) | Points + fees ($15,000-$30,000+ on $500k build) |
| Rate during build | Prime-based or locked | Prime-based floating | 10-13% fixed |
| Down payment | 20-25% of total project cost | 20-30% of construction cost | 25-35% of total project cost |
| Approval speed | 30-60 days | 30-45 days | 7-21 days |
| Permit requirement | Required before funding | Required before funding | Often required; some fund on application |
| Builder approval | Full lender vetting required | Full lender vetting required | Lighter vetting; experience-based |
Timeline: Philadelphia new construction project from lot to keys
A typical Philadelphia infill rowhouse new construction project from lot purchase to Certificate of Occupancy takes 18 to 30 months when accounting for design, permitting, construction, and inspections. Understanding this timeline is critical to staging your financing, managing cash flow, and setting realistic expectations with construction lenders who have draw expiration deadlines.
- Month 0-1: Lot acquisition (lot loan or cash), zoning confirmation, project scoping
- Month 1-3: Architectural and structural design, RCO notification (if variance needed)
- Month 3-6: ZBA variance process if required; otherwise direct to L&I permit application
- Month 4-8: L&I permit processing (6-16 weeks from complete application)
- Month 5-8: Construction loan application, borrower and builder underwriting, appraisal (as-completed value)
- Month 7-9: Construction loan close; mobilization and site prep begin
- Month 9-17: Active construction; draws released per milestone completion
- Month 17-20: Final inspections, punch list, Certificate of Occupancy issued
- Month 20-21: Permanent loan close (two-close) or automatic C2P conversion
Construction loan expiration risk: Most construction loans have a 12- to 18-month draw period. If the project runs over schedule -- common in Philadelphia due to permit delays, contractor scheduling, and supply chain issues -- you may need to request a loan extension. Extensions cost $2,000 to $5,000 in fees and require lender approval. Build a 3- to 4-month schedule buffer into your loan term request to avoid forced extensions or draw expiration. Projects that expire unfunded may require the borrower to refinance into a new construction loan at current market rates, which can be materially costly in a rising-rate environment.
Philadelphia construction risks to underwrite before you build
Permit delay risk
Philadelphia L&I permit processing times for new construction are among the longer in the metro region. Plan for 10 to 16 weeks from complete permit application submission to permit issuance for a standard residential new-build. Projects requiring structural engineering review, historic commission consultation (for properties within historic district overlays), or zoning variance processing take longer. Do not underestimate permit delay risk when structuring your construction loan term.
Construction cost overrun risk
Construction cost budgets in Philadelphia are subject to material price volatility, labor cost increases, and site-condition discoveries (buried oil tanks, contaminated soil, abandoned foundations from prior structures) that generate unforeseen costs. Budget a 10% to 15% contingency on your construction cost estimate and confirm your lender's policy on contingency -- some lenders will fund a contingency reserve; others require borrowers to hold contingency funds in a separate account. Confirm before closing how cost overruns are handled if the project runs over budget.
Mechanics lien exposure
Pennsylvania's mechanics lien statute gives subcontractors and material suppliers 6 months from the last day they provide services or materials to file a lien against the property. A mechanics lien filed against your construction project can cloud title, interfere with your permanent loan close, and in extreme cases result in a forced sale. Require unconditional lien waivers from all subcontractors and suppliers at each draw, and ensure your title insurance policy includes mechanics lien coverage. See our Philadelphia mechanics lien guide for protection protocols and the lien search process.
