Residential Design & Permit Services

Montgomery County, Maryland

Additions • Decks • Porches • Residential Renovations

Have an idea for your home but aren't sure how to turn it into an approved, buildable project? JL Enterprises SP helps Montgomery County homeowners move from the initial concept through residential design, construction drawings and the permitting process.

Over 40 Years of Residential Design & Construction Experience

From Concept to Permit

Residential projects can become complicated long before construction begins.

What can you build? What drawings will be required? How will the new work integrate with the existing home? What information will Montgomery County require during permit review?

JL Enterprises SP helps homeowners work through those questions and develop a clear path from the initial concept through permitting and construction.

Residential Design Services Include

Home Additions • Second-Story Additions • Renovations • Decks • Porches • Screened Porches • Structural Alterations • Construction & Permit Drawings • Existing-Condition Evaluations • Permit Coordination • Plan Revisions

A Straightforward Process

1. Initial Consultation

We discuss your project, goals and existing conditions to determine the appropriate next steps.

2. Design & Drawings

Your concept is developed into detailed residential construction and permit drawings.

3. Permitting

We assist with the permit submission process and address applicable plan-review comments and requested drawing revisions.

4. Construction: Your Choice

Already have a contractor? No problem. Our design and permitting services are available independently. If you need construction services, we can discuss that option as well.

Home Additions

Planning a Home Addition?

Adding space to your home can transform how it functions without requiring you to leave the property and neighborhood you already enjoy.

JL Enterprises SP can help evaluate the existing conditions, develop the proposed addition, prepare construction drawings and assist with the permitting process.

Services are available for first-floor additions, second-story additions and other residential expansions.

Deck & Porch Design

Planning a New Deck, Porch or Major Renovation?

Considering a new deck, screened porch or major renovation of an existing outdoor structure?

JL Enterprises SP provides deck and porch design, construction drawings and permitting assistance, as well as optional construction services.

Existing structures can also be evaluated to help determine whether renovation, structural repair or replacement makes the most sense.
