§ Baltimore fast facts

QUICK ANSWERS.

Do I need a contractor's license to pull door permits in Baltimore City?

Yes. Baltimore City requires a licensed home improvement contractor (MHIC license issued by the Maryland Department of Labor) for residential door replacement projects valued over $500. Commercial door work on projects above certain thresholds may also require a Maryland general contractor license. You must list your MHIC number on the permit application.

§ Built for Baltimore

LOCAL FACTS.

BALTIMORE METRO DOOR INSTALLATION LABOR RATE (RESIDENTIAL, AVG 2024).

Approximately $75–$95/hr for a journeyman door installer in the Baltimore–Towson metro area, per RSMeans 2024 regional cost data — roughly 12–18% above the national average due to prevailing wage influence and union presence in commercial work.

BALTIMORE CITY BUILDING PERMIT FEE FOR A STANDARD DOOR REPLACEMENT (RESIDENTIAL).

Baltimore City charges a minimum permit fee of $50 for residential door replacements under $5,000 in project value; fees scale to approximately $95–$150 for jobs in the $5,000–$15,000 range under the City's use-and-occupancy schedule.

CHAP HISTORIC DISTRICT COMPLIANCE REQUIREMENT.

Baltimore City's Commission for Historical and Architectural Preservation (CHAP) oversees roughly 70 designated historic districts. Replacement exterior doors in these areas must match historic character — solid wood, approved paint colors, period hardware — and require a separate CHAP approval before a building permit is issued, adding 2–4 weeks to the permitting timeline.

MARYLAND 2021 IECC EXTERIOR DOOR U-FACTOR REQUIREMENT.

Under the 2021 IECC as adopted by Maryland, opaque exterior doors must meet a maximum U-factor of 0.32 (Climate Zone 4, which covers Baltimore). Door products must carry NFRC certification or equivalent documentation to satisfy the plan reviewer — this spec should appear explicitly in your scope-of-work when you're pulling a permit.

§ Why doors pros in Baltimore use Estimate.Pro

THE BID ENGINE.

## Door Estimating in Baltimore Moves Fast — Your Bids Need to Keep Up Baltimore's housing stock is dense and old. Rowhouses in Hampden, Federal Hill, and Patterson Park were built with non-standard door openings — 30-inch rough openings that don't accept modern pre-hung units without modification, transom frames that complicate weatherstripping, and original plaster jambs that crumble on contact. When you walk a job here, you're rarely looking at a straight swap. That complexity has to show up in your bid, or you eat the difference. Estimate.Pro is built for exactly that situation. You do a walkthrough, the app captures measurements and conditions, and the AI generates a scope-of-work with line items for door units, hardware, framing modifications, weatherstripping, casing, and disposal. Median time from walkthrough to sendable bid: 8 minutes. ## What Makes Door Estimating Different in Baltimore **Historic district overlay work.** Baltimore has one of the largest concentrations of historic preservation districts in the Mid-Atlantic — Otterbein, Stirling Street, Upper Fells Point, and others fall under Baltimore City's Commission for Historical and Architectural Preservation (CHAP). Replacement doors in these districts require material-specific specs: solid wood panels, paint-grade versus stain-grade, period-appropriate hardware. Your estimate needs line items that match what the permit reviewer will scrutinize. Estimate.Pro lets you save those material specs in your workspace so the same compliant configuration loads every time. **Energy code compliance.** Maryland adopted the 2021 IECC, and Baltimore City enforces it. Exterior door U-factor requirements (U-0.32 or lower for opaque doors, per IECC Table R402.1.3) affect your product selection and need to appear in the scope-of-work if you're pulling a permit. The app surfaces this in the estimate so the inspector isn't your client's first heads-up. **Commercial work in the Inner Harbor and downtown corridor.** Hollow-metal door and frame work for commercial tenants requires different takeoff logic than residential pre-hung installs — door schedules, hardware groups, closer specifications, and coordination with the electrical rough-in for mag-holds. Estimate.Pro handles both residential and commercial door scopes under the same login. **Labor rates here aren't national averages.** Baltimore metro door installation labor runs higher than the national average. Building that into a templated estimate matters. Your saved material cost workspace in Estimate.Pro holds your actual supplier pricing from Contractors Building Supply, Hardware Specialty, or wherever you source, not a number pulled from a ZIP-code algorithm that hasn't been updated since last quarter. ## How the App Works on a Baltimore Job 1. **Walkthrough.** On supported devices, the AR measurement tool uses ONNX-assisted live detection to capture rough opening dimensions, swing direction, and existing frame condition. On older devices, camera and photo measurements are captured and flagged as estimates. 2. **AI scope-of-work.** The app drafts line items: door unit, frame modification if needed, hardware, weatherstripping, casing material and labor, haul-away, and permit allowance. 3. **Price it.** Pull from your saved material cost workspace — your real prices, not placeholder data. 4. **Send it.** The bid goes to your client as a professional document. No reformatting in Excel, no retyping in a Word template. ## Pricing That Fits How You Operate Estimate.Pro has a free tier — no credit card required, no expiration. When you're ready to take deposits and run payments through the platform, Pro is $39 per seat per month. Elite is $79 per seat per month and adds Stripe Connect with 0% platform fee and invoice exports. Crew is $399 flat per month for the whole team. On the Free tier, Stripe Connect carries a 3% platform fee. On Pro+ plans, that fee is $0. ## Built for 25 Trades, Including Yours Estimate.Pro supports 25 trades. Door contractors share the platform with framing, finish carpentry, millwork, and other trades that overlap on the same job. If you do related scope — window installs, trim work, exterior casing — you're covered under the same account. Baltimore door contractors are bidding against other shops that are still doing this in their truck with a notepad. An 8-minute bid from a clean, professional document changes how clients see you before the job starts.
