Home Additions in Chevy Chase, Maryland: Licensed Contractor 2026 Guide

Home Additions in Chevy Chase, Maryland: What Homeowners Need to Know in 2026

Chevy Chase homeowners planning an addition face a step that catches almost everyone off guard. In Chevy Chase Village, no exterior change moves forward without approval from the Village government first. That includes additions, new decks, rooflines, and sometimes even window replacements. Only after the Village signs off can a Montgomery County permit application even be submitted.

This sequence trips up homeowners who assume the process works like it does everywhere else in the county. It also trips up contractors who don’t work in Chevy Chase regularly and submit to the county first, out of habit. Getting the order right from day one is the single most important piece of local knowledge for any Chevy Chase addition.

At H&C Construction Design Build, we serve Chevy Chase homeowners with Home Additions projects across Chevy Chase Village, Section 3, and Section 5. Here is what Chevy Chase homeowners should know before adding on in 2026.

The Chevy Chase Village Approval Process

Chevy Chase Village is an incorporated Maryland municipality with its own Board of Managers. Because of this, the Village functions as a genuine local government, not just an HOA. Its Building Officer reviews and approves exterior work before any county paperwork begins.

Sections 3 and 5 operate differently. These areas sit within unincorporated Montgomery County, so additions there go straight to Montgomery County DPS without the Village review layer. However, deed restrictions in some of these neighborhoods can still affect what’s allowed on the exterior.

Height restrictions apply throughout Chevy Chase. Most of the area caps building height around 35 to 40 feet. That directly limits how much a second-story addition can add without triggering variance review. Confirming this limit during design, not after drawings are finalized, avoids a costly redesign.

Contacting the Village early saves real time. The Chevy Chase Village office reviews addition plans on a set schedule. Building that timeline into the overall project calendar prevents the most common source of delay we see in this market.

What Home Additions Cost in Chevy Chase in 2026

Chevy Chase addition costs sit at the premium end of the Montgomery County market, reflecting both labor rates and the area’s finish expectations.

Single-story rear or side addition: $200,000 to $400,000. A family room, an expanded kitchen, or a sunroom-style addition typically falls in this range depending on size and finish level. Foundation work and matching the addition to the home’s existing roofline both affect the final number.

Second-story addition: $200 to $350 per square foot. Building up requires reinforcing the existing structure and adding a new staircase. Chevy Chase’s height restrictions often shape the design before cost ever enters the conversation.

Primary suite addition over a garage or family room: $150,000 to $300,000. This remains one of the most requested addition types in Chevy Chase, since it adds meaningful square footage without expanding the home’s overall footprint.

Budgeting for the unexpected. Add a 15 to 20 percent contingency to any Chevy Chase addition estimate. Homes built in the early twentieth century commonly reveal foundation or framing surprises once construction actually begins.

Why Chevy Chase Additions Require Extra Planning

Architectural matching matters as much as square footage. A poorly matched addition stands out immediately in a neighborhood known for architectural consistency. Rooflines, brick coursing, and window proportions all need to read as original rather than added later.

Structural engineering is required for anything built up. An engineer has to confirm the existing foundation and framing can support the added weight of a second story. This step belongs in the design phase, well before Village or county submission.

Mature trees and tight setbacks shape what’s possible. Many Chevy Chase lots have significant tree canopy and established landscaping that constrain where an addition can go. Site assessment early in design prevents surprises once construction crews arrive.

The Permit Process for a Chevy Chase Home Addition

Village approval comes first when it applies. Confirming whether your property falls within Chevy Chase Village, Section 3, or Section 5 determines the entire sequence. This is always the first call to make.

Montgomery County DPS review follows Village approval. Standard review for residential additions typically runs 6 to 10 weeks once the application is complete and any Village conditions are satisfied.

Structural drawings are required at submission. Any addition involving new framing or a second story needs engineer-stamped calculations included with the application package.

Final inspection closes out the project. Each trade signs off as its portion of the work completes, and a final county inspection precedes the certificate of occupancy for the new space.

What Chevy Chase Buyers Look For in a Well-Executed Addition

A seamless match to the original home reads as quality. Buyers touring Chevy Chase listings can usually spot an addition that wasn’t planned with the existing architecture in mind. It works against the home’s perceived value.

Purposeful rooms outperform vague bonus space. A primary suite with a genuinely well-designed bathroom beats an undefined flex room. Buyers in this market compare homes on specific, well-executed spaces rather than raw square footage.

Respecting the neighborhood’s character pays off at resale. Chevy Chase buyers consistently favor additions that feel like they belong, over additions that read as an obvious later add-on.

How to Choose a Home Addition Contractor in Chevy Chase

Confirm Maryland licensing first. Verify MHIC credentials at dllr.state.md.us before any design conversation begins, and confirm liability coverage above Maryland’s $500,000 statutory minimum.

Ask specifically about Village approval experience. A contractor who has submitted addition plans to Chevy Chase Village before can walk you through the process in detail. One who hasn’t may not even know the step exists.

Review a local portfolio of comparable additions. Ask for photos and addresses of completed additions in Chevy Chase from the past two years, then call the homeowners directly.

Insist on engineer-stamped drawings before permitting. Any addition involving structural changes should have these prepared during design, well ahead of submission.

Bathroom Remodeling in Chevy Chase, Maryland: Licensed Contractor 2026 Guide

Bathroom Remodeling in Chevy Chase, Maryland: What Homeowners Need to Know in 2026

Chevy Chase is one of the Washington region’s most historically significant residential communities. Its large Colonial Revivals, Tudors, Queen Anne Victorians, and foursquares were built largely between the 1890s and 1930s as one of America’s first streetcar suburbs. These homes are beautiful, but they often have bathrooms that are original, retrofitted, or undersized for the home’s overall scale. Because of this specific housing character, bathroom renovation here requires a different skill set than renovation in newer Montgomery County communities like Gaithersburg or Germantown.

Furthermore, Chevy Chase presents a permitting complexity that most contractors don’t fully understand. Bathroom renovation in this community involves Montgomery County DPS permits, WSSC coordination for plumbing, and in some cases individual village or town reviews depending on which section of Chevy Chase your property falls within. In practice, understanding this layered process before design begins is the most important preparation any Chevy Chase homeowner can make.

At H&C Construction Design Build, we serve Chevy Chase homeowners with Bathroom Remodeling projects across Chevy Chase Village, Section 3, Section 5, Hamlet, Martin’s Additions, Drummond, Bradford Hills, and Friendship Heights. Here is what Chevy Chase homeowners need to know before starting a bathroom renovation in 2026.


The Chevy Chase Permitting Reality

This is the single most important thing a Chevy Chase homeowner can know before starting a bathroom renovation. Bathroom renovation navigation in this community involves Montgomery County DPS and WSSC permits plus the individual village and town reviews that the “Chevy Chase” name actually entails.

Chevy Chase Village is an incorporated Maryland municipality with its own Board of Managers. Because of this, exterior changes in Chevy Chase Village require Village approval before Montgomery County DPS permits are submitted. Interior bathroom renovations that don’t affect the exterior typically bypass Village review. However, a contractor unfamiliar with this distinction may not understand where the line falls for your specific project.

Chevy Chase Sections 3 and 5 fall within unincorporated Montgomery County. As a result, these properties permit directly through Montgomery County DPS without the Village governance layer. However, deed restrictions and HOA covenants in some Section 3 and 5 neighborhoods still govern certain exterior changes. Confirming your specific property’s governing requirements before design begins prevents costly sequencing errors later.

WSSC permit coordination adds another layer. Beyond the building permit, plumbing work in Chevy Chase, including shower drain changes, vanity plumbing, and wet bar additions, requires separate Washington Suburban Sanitary Commission coordination. Because of this, a comprehensive bathroom permit package in Chevy Chase includes Montgomery County DPS building and electrical permits plus WSSC coordination for any plumbing scope. An experienced Chevy Chase contractor manages all of these simultaneously as a matter of standard practice.


What Bathroom Renovation Costs in Chevy Chase in 2026

Chevy Chase bathroom renovation costs reflect Montgomery County’s premium labor market and the specific conditions of its historic housing stock.

Powder room update: $6,000 to $15,000. A new vanity, toilet, lighting, and flooring transform a half bath quickly. Furthermore, no shower work means this scope avoids the most labor-intensive waterproofing steps.

Secondary or hall bathroom: $15,000 to $35,000. Complete tile replacement, new vanity, new toilet, updated GFCI electrical, and exhaust fan. In practice, Chevy Chase’s pre-war homes regularly surface plumbing and electrical conditions during demolition that push costs toward the upper end of this range. A 15% contingency is standard professional practice.

Primary suite bathroom: $35,000 to $80,000. This is the most requested scope in Chevy Chase’s established neighborhoods. The scope typically includes a custom tile curbless walk-in shower, double vanity, frameless glass enclosure, and quality fixtures throughout. Furthermore, heated floors have become a standard expectation at this tier in Chevy Chase’s $1.3M and above housing market.

Luxury primary suite: $80,000 to $130,000 or more. For Chevy Chase Village and Section 5 properties trading above $1.8 million, primary bathroom renovation at spa specification is appropriate and well-supported by the surrounding market. Steam shower, natural stone throughout, and custom vanity cabinetry characterize this tier.

Permit fees. Chevy Chase bathroom projects file with Montgomery County DPS. Standard electrical and plumbing permits run $500 to $1,500. Additionally, WSSC coordination adds time and sometimes fees depending on the specific plumbing scope.


Chevy Chase’s Housing Stock: What Each Era Requires

Chevy Chase’s architectural diversity creates meaningfully different renovation conditions by section and era.

1890s to 1930s Colonial Revivals, Tudors, and Victorians. These are Chevy Chase’s oldest and most architecturally significant homes. From Chevy Chase Village through Section 5, each section has its own architectural character and renovation requirements. In practice, bathroom renovation in these homes involves the most discovery: plaster walls, original cast iron plumbing, knob-and-tube electrical, and subfloor conditions from a century ago. Because of this, a 15 to 20% contingency is essential for any pre-1940 Chevy Chase bathroom renovation.

Mid-century infill from the 1940s through 1960s. Some Chevy Chase sections contain homes built during the community’s postwar growth years. These homes have better baseline structural conditions than pre-war properties but still carry aging systems that commonly surface during demolition. In practice, supply line replacement and panel upgrades often accompany primary bathroom renovation in this tier.

Contemporary custom infill. Newer custom homes in Chevy Chase, built on lots where earlier structures were removed, call for a different renovation approach. Because these properties have current-code systems and more generous bathroom footprints, renovation focuses on premium finish upgrades rather than system remediation.


What Chevy Chase Buyers Expect in a Renovated Bathroom

Chevy Chase’s premium resale market sets a clear finish standard. Buyers comparing Chevy Chase Village and Section 5 listings evaluate bathroom quality with genuine sophistication.

Period-sympathetic design is rewarded. In Chevy Chase’s historic homes, bathroom renovation that respects the home’s era performs consistently better at resale. Tile profiles, fixture styles, and material choices that reference the home’s original decade distinguish well-considered renovation from renovation that simply treats these homes as generic structures.

Curbless walk-in showers are now the baseline expectation. However, in historic homes, curbless shower design must work within potentially constrained footprints. As a result, linear drains that permit flexible drain placement are commonly specified in Chevy Chase’s narrower bathroom configurations.

Double vanities signal proper scale. Beyond aesthetics, a double vanity signals that the bathroom was designed for two people. This is the standard expectation in Chevy Chase’s family-oriented buyer pool. Furthermore, quality fixtures in period-appropriate finishes communicate attention to detail that buyers in this market notice and remember.


The Renovation Process: What to Expect Phase by Phase

Understanding each phase prevents the most common homeowner frustrations.

Design and selection (2 to 5 weeks). First, all tile selections, vanity specifications, fixture choices, and layout decisions are finalized. Specifically, plumbing fixture positions must be decided during design. Because moving a shower drain in a Chevy Chase home can require saw-cutting a concrete slab, this decision carries real cost implications. Settling it in design prevents costly mid-project changes.

Permit applications (5 to 8 weeks). Montgomery County DPS processes bathroom renovation permits in 5 to 8 weeks for major work and 2 to 3 weeks for straightforward scopes. Because of this, the permit timeline is a fixed part of every Chevy Chase bathroom renovation calendar.

Demolition and assessment (3 to 5 days). In Chevy Chase’s pre-1940 housing stock, demolition commonly surfaces corroded plumbing, inadequate electrical capacity, or subfloor moisture damage. A 15% contingency above the construction estimate accounts for these discoveries without requiring scope changes mid-project.

Waterproofing and rough-in (1 to 2 weeks). Plumbing rough-in, electrical rough-in, and shower waterproofing membrane installation happen while walls are open. Each trade requires a county inspection before walls close. Full WEDI or equivalent system coverage is the correct standard for curbless shower construction.

Tile installation and finish work (2 to 4 weeks). Large-format tile, vanity setting, fixture installation, and frameless glass fabrication follow in sequence. Frameless glass is measured after tile completion and fabricated in 1 to 2 weeks. Finally, the Montgomery County final inspection closes the project.


How to Choose a Bathroom Remodeling Contractor in Chevy Chase

MHIC license verification is always the first step. Verify at dllr.state.md.us before any design conversation. Maryland requires minimum $500,000 general liability insurance since June 2024. Because Chevy Chase projects regularly reach $80,000 to $130,000 or more, confirming adequate insurance coverage protects a significant investment.

Multi-layer permit knowledge matters. Ask directly: “Are you familiar with the specific permitting requirements for my section of Chevy Chase, including WSSC coordination and Village review if applicable?” A contractor who does not immediately understand these distinctions has not worked regularly in this community.

Historic construction experience is essential. Ask specifically whether the contractor has completed bathroom projects in pre-1940 Chevy Chase homes. Furthermore, ask how they handle plaster wall repair, original hardwood floor protection, and period-sympathetic tile sourcing. Contractors who regularly work in historic construction have specific, detailed answers to these questions.

Written scope with full material specifications. Every tile selection, every fixture model, every plumbing position, and every scope item should appear in writing before signature. Because Chevy Chase projects involve expensive materials and complex historic conditions, a complete written contract is not optional.
