Ask Baily about your Boston remodel and you will not be passed around. Boston is the densest pre-war housing market in the United States by share of stock, and its regulatory stack — the Massachusetts Construction Supervisor License, the Boston Landmarks Commission's eight designated districts, the Massachusetts Lead Law on pre-1978 stock and the Massachusetts Stretch Code — makes quote-spray sites like Angi genuinely unfit for the market. A Beacon Hill townhouse, a Back Bay brownstone flat, a South End bow-front and a triple-decker in Jamaica Plain each answer to different rulebooks, different de-leading obligations and different envelope-energy requirements. Baily holds that context. We introduce one Baily-vetted Boston builder who holds an active Massachusetts Construction Supervisor License (CSL) at the appropriate classification, who engages Massachusetts-licensed electricians under 527 CMR 12 and plumbers under 248 CMR 10, who has presented before the Boston Landmarks Commission, and who has delivered a compliant Massachusetts Lead Law de-leading project. One pro per homeowner, from the first enquiry through Certificate of Occupancy. No quote spray, no twelve strangers. The builder we introduce is the builder who walks the final inspection with you.
The Boston remodel market in 2026
Boston is one of the highest per-project renovation markets in the United States. The Warren Group reported Greater Boston's median single-family home price crossed US$800,000 in 2023 [verify — The Warren Group Greater Boston 2023 market report]. The City of Boston Inspectional Services Department issued approximately 24,000 residential building permits in fiscal year 2023 [verify — Boston ISD FY2023 permit activity]. At the project level, a mid-range Boston kitchen renovation typically runs US$55,000 to US$130,000 supplied and installed, with designer kitchens in Back Bay, Beacon Hill, South End and Cambridge (Harvard Square-adjacent) regularly exceeding US$250,000 once custom millwork, natural stone and Wolf or Sub-Zero packages are included (Houzz US Kitchen Trends Study 2024 Boston metro, Massachusetts Association of REALTORS Q4 2023 market reports [verify]). Bathroom renovations sit between US$25,000 and US$65,000 for a primary bath. Whole-home refurbishments on four-bedroom Greater Boston single-family and townhouse properties commonly run US$275,000 to US$800,000, with Beacon Hill and Back Bay whole-home projects regularly exceeding US$1.8 million.
The housing stock is unusually old. Federal and Greek Revival single-family and townhouse stock from the 1790s-1840s defines Beacon Hill, Bay Village and parts of the North End. Victorian and Italianate townhouse stock from the 1850s-1890s fills Back Bay, the South End and parts of South Boston. Triple-decker and two-family stock from the 1890s-1920s dominates Jamaica Plain, Dorchester, Roxbury and parts of Somerville. Post-war single-family stock fills Newton, Brookline, Lexington and the inner suburbs. Per the Massachusetts Association of REALTORS, more than 55 percent of Greater Boston's housing stock predates 1940 [verify — MAR 2023 Greater Boston market report]. Renovating homeowners split between multi-generation Beacon Hill, Back Bay and Newton families undertaking once-in-a-generation refurbishments, mid-career South End and Jamaica Plain upgraders investing in whole-home gut renovations, and Cambridge and Somerville owner-occupants renovating triple-decker and two-family stock. The 2026 trend favours kitchen-and-primary-bath gut renovations within period envelope, Massachusetts Stretch Code-compliant envelope and mechanical upgrades, de-leading-paired gut renovations on pre-1978 stock, and townhouse whole-home refurbishments coordinated with Boston Landmarks Commission where applicable.
What homeowners need to know about Boston regulations
Massachusetts Construction Supervisor License (CSL) — Unrestricted and Restricted. Massachusetts licenses construction supervisors at the state level under 780 CMR 110.R5 and Massachusetts General Laws Chapter 143 §94 and §95. The Unrestricted CSL authorises supervision of buildings of any occupancy and any size. The Restricted CSL (1-2 Family Dwellings) authorises supervision of 1-2 family residential construction only. Any residential renovation requiring a building permit requires a licensed construction supervisor on site responsible for the work. Unlicensed supervision is prosecutable under state statutes. Baily verifies CSL classification, workers' compensation, general liability and Board of Building Regulations and Standards disciplinary history on every partner before the first introduction. Home Improvement Contractor (HIC) registration under MGL Chapter 142A is also verified for contracts with homeowners on owner-occupied 1-4 family dwellings.
Boston Landmarks Commission and eight designated districts. The City of Boston has eight Landmark Districts under Boston Landmarks Commission jurisdiction: Back Bay, Beacon Hill, Bay Village, South End, Fort Point Channel, Aberdeen, Mission Hill Triangle, and St. Botolph Street. Any exterior work affecting a designated property requires a Boston Landmarks Commission Certificate of Design Approval, with staff-level approval available for minor scopes and full Commission hearings for substantial exterior alterations. The Back Bay Architectural Commission and Beacon Hill Architectural Commission operate as district-specific review bodies with their own quorum and hearing calendars. Expect Landmark review to add four to ten weeks to the permit timeline.
Massachusetts Lead Law (MGL Chapter 111 §§189A-199B) and pre-1978 de-leading. Massachusetts has one of the most stringent lead-paint laws in the United States. Any residence built before 1978 occupied by a child under 6 must be de-leaded to a Letter of Full Deleading Compliance or Letter of Interim Control issued by a licensed Massachusetts Lead Inspector. Sale or rental of pre-1978 units to families with children under 6 triggers disclosure and de-leading obligations. Renovations on pre-1978 stock require a licensed lead-safe renovator (Massachusetts Lead-Safe Renovator certification, aligned with EPA RRP Rule). Baily's partner builders hold Lead-Safe Renovator credentials and coordinate with Mass licensed Lead Inspectors on every pre-1978 scope.
Massachusetts Stretch Code (780 CMR 115.AA). Massachusetts adopts the Stretch Energy Code as an optional above-baseline energy code that over 300 Massachusetts municipalities, including Boston, Cambridge, Somerville, Brookline and Newton, have made mandatory as Green Communities. The 2023 Stretch Code imposes tighter envelope, fenestration U-value and mechanical performance than the base Massachusetts Energy Code. Renovations meeting defined alteration thresholds trigger Stretch Code compliance. Opt-in Specialized Code applies in some municipalities with Net Zero provisions.
Snow-load engineering and coastal-flood V and AE zones. Boston's design ground snow load under ASCE 7-22 and 780 CMR amendments is typically 40 psf, with higher values in outer suburbs. Roof additions and pop-top additions require snow-load engineering. Coastal blocks in South Boston, East Boston, Charlestown and parts of Jamaica Plain sit inside FEMA-mapped V and AE zones with substantial-improvement elevation rules. Waterfront Back Bay and the Seaport carry additional climate-resilience review.

Frequently asked questions — Boston
How long does a permit take for a typical Boston kitchen renovation?
For an interior-only kitchen renovation that triggers plumbing, electrical or minor structural scope, the Boston Inspectional Services Department typically issues a residential alteration permit in four to ten weeks via Boston BuildingLink. Renovations involving structural scope, pre-1978 de-leading-paired work or exterior envelope work take six to fourteen weeks with Stretch Code and Lead Law compliance review. Boston Landmarks Commission, Back Bay Architectural Commission and Beacon Hill Architectural Commission review adds four to ten weeks and runs in parallel. Cambridge, Somerville, Brookline and Newton operate independent timelines.
What licenses and insurance do you verify on your partner builder?
We verify Massachusetts Construction Supervisor License classification and status on the BBRS public search, Massachusetts Home Improvement Contractor registration where the contract is for an owner-occupied 1-4 family dwelling, 527 CMR 12 electrician licences for in-house electrical trades, 248 CMR 10 plumber licences for in-house plumbing trades, minimum US$2 million general liability insurance, workers' compensation coverage, BBRS and trade-board disciplinary history, and references on comparable Boston-area projects. For pre-1978 work, we verify Massachusetts Lead-Safe Renovator certification.
How are payments structured in Boston?
Massachusetts residential contracts under MGL Chapter 142A cap initial deposits at one-third of the contract price or the actual cost of special-order materials, whichever is greater. Progress draws tie to demolition, rough-in, drywall, finish and substantial completion. Retention of 5 to 10 percent is held through final inspection and the defects period. All amounts are in US dollars. Baily does not take homeowner funds — payments go directly to your builder against contract stages.
How do you handle my personal data?
Massachusetts 201 CMR 17.00 imposes comprehensive data-security standards on businesses handling personal information of Massachusetts residents. Baily complies with 201 CMR 17.00 and applies CCPA-equivalent access, correction and deletion rights to Massachusetts residents as a matter of policy. Your enquiry data is processed to match you to a builder and is never sold.
What language does Baily handle?
English is the primary service language for Boston. Baily's natural-language layer also handles Spanish, Portuguese, Haitian Creole, Mandarin and Vietnamese for Boston's community languages, given Greater Boston's significant Brazilian-Portuguese, Haitian, Chinese and Vietnamese communities per US Census ACS 2022. Written contracts and Massachusetts CSL and HIC paperwork are issued in English; translated plain-language summaries are available on request.
How is a dispute resolved if something goes wrong?
We encourage direct resolution first. If escalation is needed, the Massachusetts Office of Consumer Affairs and Business Regulation administers the Home Improvement Contractor program, including a Guaranty Fund paying eligible homeowners up to US$10,000 per claim. The Massachusetts Attorney General Consumer Protection Division covers broader consumer-fraud matters. Massachusetts District Court Small Claims handles matters up to US$7,000. Arbitration under MGL Chapter 251 is available.
Press and podcast coverage
We are targeting launch coverage in Boston Magazine, Boston Home Magazine, Design New England, New England Home, Boston Globe Real Estate, Curbed Boston and Boston Business Journal. Business-press angles sit with the Boston Globe real estate desk and Axios Boston. Podcast targets include The Boston Real Estate Podcast, Home on the Hub and Beantown Built. The Boston story is specific: Angi and peers fan a South End bow-front gut renovation or Beacon Hill whole-home project out to twelve contractors without knowing whether any of them have presented before the Beacon Hill Architectural Commission, coordinated a Massachusetts Lead Law de-leading Letter of Full Compliance or delivered Stretch Code-compliant envelope upgrades. AskBaily introduces one Massachusetts CSL-licensed builder with verified Landmark, Lead Law and Stretch Code track record before the first phone call. Launch timing pairs with Boston chapter events of the National Association of the Remodeling Industry (NARI) and the Builders and Remodelers Association of Greater Boston.
