§ Dallas fast facts

QUICK ANSWERS.

Do I need a separate permit for the HVAC work on a Dallas home addition?

Yes. The City of Dallas requires separate mechanical, electrical, and plumbing permits in addition to the base building permit. Your HVAC subcontractor must pull their own mechanical permit, and the load calculation supporting any equipment change must be available for inspection. A Manual J calculation is the standard method for justifying equipment sizing on addition projects.

§ Built for Dallas

LOCAL FACTS.

DALLAS RESIDENTIAL FRAMING LABOR RATE (2024 DFW METRO AVG).

Framing labor in the DFW metro runs approximately $6.50–$8.50 per square foot for addition framing, depending on complexity and crew source. Multi-story additions trend toward the upper end.

CITY OF DALLAS BUILDING PERMIT FEE — REPRESENTATIVE ADDITION.

For a $150,000 addition valuation, Dallas Building Inspection typically assesses combined permit and plan review fees of $1,400–$1,700 under its valuation-based fee schedule. Fees are calculated per the adopted fee table and require a separate mechanical, electrical, and plumbing permit for each trade.

ADOPTED BUILDING CODES — CITY OF DALLAS.

Dallas has adopted the 2021 International Residential Code (IRC) and the 2020 National Electrical Code (NEC). Addition projects must comply with current energy code requirements under the 2021 IECC as locally amended.

FOUNDATION CONDITION NOTE — NORTH TEXAS EXPANSIVE CLAY.

Dallas sits on expansive black clay (Houston Black series soils). Most addition contractors in the market specify post-tension slabs or drilled pier-and-grade-beam systems for new addition foundations. A geotechnical report is often required by plan reviewers for additions over 400 sq ft.

DALLAS ADDITION CONTRACTOR MARKET — PEAK SEASON.

Addition permit filings in Dallas historically peak in the March–June window as homeowners finalize projects before summer heat sets in. A secondary surge occurs September–November. Addition contractors who can turn bids quickly during these windows win a disproportionate share of signed contracts.

§ Why new additions pros in Dallas use Estimate.Pro

THE BID ENGINE.

## Addition Estimating in Dallas Moves Fast — Your Bids Need to Keep Up Dallas is one of the busiest residential construction markets in the country. The demand for home additions — master suite expansions, second-story additions, ADUs, garage conversions — has held strong across Preston Hollow, Lake Highlands, Oak Cliff, and the suburban belt stretching into Plano, Richardson, and Garland. Homeowners here expect a professional bid fast, and they're comparing you against three or four other addition contractors before they sign anything. Slow estimates kill deals. Estimate.Pro gets you from a phone walkthrough to a sendable bid in 8 minutes. --- ## What Makes Addition Estimating Different in Dallas **Foundation type drives everything.** North Texas expansive clay soil means most Dallas additions require a post-tension slab or pier-and-beam extension rather than a simple monolithic pour. Your estimate has to account for geotechnical conditions from the start. Estimate.Pro's scope-of-work builder includes foundation type as a required field, so it never gets buried in a line-item note and forgotten. **MEP coordination is non-negotiable.** A 400-square-foot addition in Dallas typically involves extending HVAC (with a Manual J load calculation to justify equipment sizing), rerouting plumbing drain lines, and adding circuits under the current NEC adoption cycle. The City of Dallas has adopted the 2021 IRC and 2020 NEC. Your bid has to reflect code-compliant scope, not guesses. **Permit fees are real money.** Dallas Building Inspection charges permit fees based on valuation. A $150,000 addition can carry permit and plan review fees north of $1,500 before your first nail goes in. Estimate.Pro lets you build permit cost into your line items so it's visible to the client — not absorbed silently into your margin. **Material costs shift quarter to quarter.** Lumber, concrete, and framing labor in the DFW metro have seen significant volatility. Estimate.Pro keeps a saved material cost workspace so you update unit prices once and every active estimate reflects the current number. You're not re-keying the same framing cost into a spreadsheet every week. --- ## How Estimate.Pro Works for Addition Contractors **Walkthrough capture.** Walk the job with your phone. On supported devices, ONNX-assisted live AR measurement gives you room dimensions in real time. On other devices, camera and photo measurements are flagged as estimates — you always know what's confirmed and what needs verification. **AI scope-of-work.** After the walkthrough, the AI drafts a scope: foundation type, framing spec, sheathing, roofline tie-in, windows, exterior finish, MEP rough-in allowances, insulation, and interior finish schedule. You review and edit. Nothing gets sent without your sign-off. **Priced estimate.** Your saved cost data populates the line items. Labor rates, material unit costs, subcontractor allowances — pulled from your own workspace, not a national average that doesn't match DFW reality. **Send it.** The client gets a professional, itemized proposal. If you're on Pro+ (Elite tier at $79/seat/month), you can collect a deposit through Stripe Connect with zero platform fee. On the Free tier, Stripe Connect runs at 3%. --- ## Pricing That Fits Your Operation - **Free forever** — no credit card, no trial clock. Enough to run real jobs. - **Pro** — $39/seat/month. Full cost workspace, unlimited estimates. - **Elite** — $79/seat/month. Stripe Connect at 0%, invoice exports, advanced workflows. - **Crew** — $399/month flat for your whole team. No per-seat math when you're running multiple crews across DFW. --- ## Built for the Way Dallas Addition Contractors Actually Work You're not bidding cookie-cutter jobs. Every addition in Dallas has a different foundation condition, a different existing electrical panel situation, a different roofline to tie into. You need estimating software that follows your process — not one that forces you into a template built for a painting contractor. Estimate.Pro supports 25 trades, and the additions workflow is built around the full scope: site prep through final finish. The 8-minute median from walkthrough to sendable bid isn't a marketing figure — it's the median across contractors using the platform on real jobs. Start free. No credit card. Run your next Dallas addition bid through it and see where it lands.
