§ Baltimore fast facts

QUICK ANSWERS.

Do I need a license to install irrigation systems in Maryland?

Yes. Maryland requires irrigation contractors to hold a Master Home Improvement Contractor (MHIC) license for residential work. Commercial irrigation work connecting to a potable water supply may also require a licensed plumber to perform or supervise the backflow preventer installation. Baltimore City additionally requires a local business license.

Are rain sensors required on new irrigation systems in Baltimore?

Maryland law (MD Code, Environment §9-207.1) requires automatic irrigation systems installed after October 1, 2010 to include a rain sensor or soil moisture sensor that shuts off the system during or after adequate rainfall. This applies to systems in Baltimore City and Baltimore County and must be reflected in your scope and bid.

BALTIMORE COUNTY PLUMBING PERMIT FEE FOR NEW IRRIGATION SYSTEM.

§ Why irrigation / sprinkler pros in Baltimore use Estimate.Pro

THE BID ENGINE.

## Irrigation Estimating in Baltimore Moves Fast — Your Bids Should Too Baltimore's climate drives two hard rushes for irrigation contractors: spring system startups through May, and late-summer installs before the Chesapeake Bay watershed restrictions tighten in fall. Between those windows, your estimating process either keeps pace or costs you jobs. Estimate.Pro gives you a walkthrough-to-bid workflow built for the trades. Pull up a residential or commercial property, walk the site with the app, and generate a priced scope of work in a median of 8 minutes. No spreadsheet archaeology. No chasing down material prices you saved three months ago. ### What Makes Baltimore Irrigation Jobs Different **Soil and site conditions matter here.** Much of the Baltimore metro sits on clay-heavy Piedmont soils with scattered rock ledges, especially in areas like Towson, Catonsville, and the older Hampden neighborhoods. Trenching depth and lateral spacing for head placement directly affect your labor estimate. Estimate.Pro lets you document soil conditions during the walkthrough so those notes live inside the scope, not in a text thread. **Local water restrictions shape system design.** Baltimore City and Baltimore County properties near Chesapeake Bay tributaries fall under Maryland's Phase II MS4 stormwater requirements, and Bay-sensitive design often means pressure-regulated heads, rain sensors, and smart controllers are specified rather than optional. Those line items carry real cost differences — Estimate.Pro's saved material cost workspace lets you store your preferred sensor and controller SKUs with current pricing so your bids reflect what you actually buy. **Permit pull timing matters.** Baltimore County requires a plumbing permit for any new irrigation system connecting to a potable water supply. Plan review adds days to your start date. When you're quoting a job, that delay is either in your scope or it's a surprise you eat later. ### From Walkthrough to Sendable Bid On a supported device, Estimate.Pro's ONNX-assisted live AR measurement gives you zone dimensions and head-count estimates during the site visit. On any device, photo measurements work as clearly marked estimates. Either way, you're not going back to the truck to rebuild numbers from notes. The AI scope-of-work generator builds line items from your walkthrough inputs — backflow preventer, valve manifold, controller, head type and count, trenching linear footage, and startup/winterization provisions. You review, adjust, and send. The median time from walkthrough to a sendable bid is 8 minutes. ### Pricing Built for Irrigation Contractors Estimate.Pro runs on a free forever tier — no credit card, no trial clock. When your volume grows, Pro is $39 per seat per month. Elite at $79 per seat per month adds Stripe Connect payments (0% platform fee on Pro+), invoice exports, and the full workflow stack. If you're running a crew, the Crew plan is $399 flat per month for the whole shop. On the Free plan, Stripe Connect carries a 3% platform fee. On Pro and above, that fee drops to 0%. ### Why Irrigation Contractors Use It You're bidding against companies that still email PDF estimates three days after the site visit. A same-day, itemized bid with a professional scope of work — sent from the parking lot — closes more jobs. That's not opinion. It's what faster response time does in a competitive local market. Baltimore irrigation contractors also deal with a short effective season. Every bid that drags kills margin on jobs you should have already started. Tighten the estimating step and you recover that time downstream. Estimate.Pro supports 25 trades. If your shop also handles drainage, hardscape, or outdoor lighting, those scopes live in the same platform. One walkthrough can feed multiple trade estimates. Start free at Estimate.Pro. No credit card required.
