Building a porch costs $40 to $120 per square foot for a standard open porch — the same rate all three sources publish — putting a 200-square-foot porch at $8,000 to $24,000 on the sibling size tables123. HomeGuide’s range for a 200-square-foot porch is $8,000 to $30,000 (February 2026)1. Angi and HomeAdvisor are corporate siblings, and matching figures alone don’t establish independent corroboration — their tables match on nearly every row below, with HomeGuide providing the separate comparison. Two published figures are omitted here: HomeAdvisor’s headline ($4,000 to $7,200 normal range, $14,500 average) contradicts its own size table, and Angi’s lead repeats the $14,500 with a per-square-foot unit its own tables don’t support. The size tables, which are internally consistent with the published per-square-foot rates, are used instead. All figures are the latest published data from each source.
Cost by size
The siblings’ matching size table (HomeAdvisor’s rows shown; Angi adds intermediate sizes at 150, 250, 350, 450, and 550 square feet on the same $40 to $120 rate)23:
| Square feet | Average cost |
|---|---|
| 80 | $3,200 – $9,600 |
| 100 | $4,000 – $12,000 |
| 200 | $8,000 – $24,000 |
| 300 | $12,000 – $36,000 |
| 400 | $16,000 – $48,000 |
| 500 | $20,000 – $60,000 |
| 600 | $24,000 – $72,000 |
HomeGuide’s dimensioned table runs higher at the top end — its 200-square-foot row is $8,000 to $30,000, and it extends to 600 square feet at $24,000 to $90,0001.
Cost by porch type
HomeGuide’s type table1:
| Type | Cost per sq ft | Average total cost |
|---|---|---|
| Front porch | $40 – $120 | $6,000 – $18,000 |
| Back porch | $40 – $120 | $9,000 – $27,000 |
| Screened-in porch | $50 – $175 | $10,000 – $35,000 |
| Enclosed porch | $80 – $400 | $16,000 – $80,000 |
| Wrap-around porch | $60 – $150 | $27,000 – $67,500 |
| Farmer’s porch | $60 – $150 | $15,000 – $37,500 |
| Portico | $100 – $185 | $4,000 – $15,000 |
| Prefabricated porch (DIY kit) | $25 – $50 | $2,500 – $10,000 (materials) |
The siblings frame types per square foot only: open porch $40 to $120, wraparound and veranda $60 to $150, screened-in $25 to $120, and multi-season $115 to $200 (Angi only)23. Screened-in pricing diverges between the publishers — $25 to $120 on the siblings against $50 to $175 on HomeGuide; ranges as published123. HomeAdvisor separately prices a small 8×10 front porch at $1,900 to $8,8003.
Foundations, roofing, and railings
The siblings publish identical foundation and component rates23:
| Component | Average cost |
|---|---|
| Concrete foundation | $2 – $10 per sq ft |
| Wood foundation | $4 – $30 per sq ft |
| Composite foundation | $25 – $55 per sq ft |
| Pier and beam foundation | $7 – $12 per sq ft |
| Roofing | $30 – $160 per sq ft |
| Flooring | $4 – $32 per sq ft |
| Railings | $15 – $600 per linear ft |
| Stairs | $120 – $300 per step |
HomeGuide’s calculator table adds installed-cost rows the siblings don’t break out: gable roof $70 to $155 per square foot, flat roof $20 to $60 per square foot, skirting $25 to $30 per square foot, screens $10 to $25 per square foot, a set of 5 to 10 steps $500 to $5,000, an electrical outlet $180 to $350, lighting $80 to $300 per fixture, a damp-rated ceiling fan $300 to $1,500 installed, and old porch removal $675 to $2,2501. For DIY material browsing, Home Depot’s deck railing category covers wood, composite, and metal options (non-affiliate link).
Materials vs labor
HomeGuide splits the $40 to $150 blended rate into materials at $22 to $100 per square foot and labor at $18 to $50 per square foot1. The siblings mix units: materials 50% to 65% of the project total on both, with labor at 35% to 55% of the total (Angi) and $20 to $50 per square foot (both siblings)23.
Permits and timeline
Permit rules are set locally — confirm with your building department before starting. Published estimates: $150 to $500 on HomeGuide (with fees increasing over 200 square feet), against $150 to $2,000 on both sibling pages123. HomeGuide’s timeline: 4 to 6 weeks to build, plus 1 to 4 months for permit processing, or 2 to 7 days to add screens and a simple roof over an existing foundation1.
