About

Common Questions
Who manages the Northbrook Community Association and how are decisions made?
The Northbrook Community Association is governed by three volunteer homeowners elected to overlapping three-year terms at an annual meeting held each fall. Administrative and financial functions are handled through Cyron & Company, PO Box 470, West Grove, PA 19390. The Association requires prior written approval before any exterior structural or landscaping changes are made. Buyers should request and review current governing documents, dues schedules, and the Association’s financial statements before closing.
Which school does Northbrook feed into at the elementary level?
The most common elementary school assignment for Northbrook is Bethel Springs Elementary School, located at 3280 Foulk Road, Garnet Valley, PA 19060 (part of the Garnet Valley School District). Bethel Springs serves grades K–5 with approximately 530–550 students and a student-to-teacher ratio near 11:1. State proficiency data shows students outperform Pennsylvania averages in both math and reading. Buyers should confirm current boundary assignments directly with the Garnet Valley School District, as attendance zones can change.
What builder constructed Northbrook and when were the homes built?
Northbrook was developed by Blenheim Homes, which marketed the community as its ‘premier community in Delaware County.’ Construction spanned approximately 2004 to 2009, with a median build year around 2006. The carriage-home product featured three distinct floor-plan models with 9-foot ceilings across multiple levels. A separate third-party real estate data source notes construction ran through approximately 2013 for later phases. Buyers should verify the specific year built for any individual home through Delaware County public records.
Items to Verify with Your Agent
A few specifics on this page are sourced from secondary aggregators or older filings. Confirm before relying:
- Builder — Blenheim Homes is confirmed as the carriage-home builder from a 2004 Philadelphia Inquirer newspaper advertisement (newspapers.com). Whether Blenheim also built the 15 detached single-family homes or whether a separate builder was responsible for that product type is not confirmed by any source found.
- Hoa Notes — Specific Current Dues Amount — The Northbrook Community Association website confirms dues are collected and managed via Cyron & Company and references both annual and monthly fee structures, but does not publish a specific current dollar amount. A third-party real estate site (scottkompa.com) cites a range of $50–$100/month with some annual fees around $1,000, but this is not verified from the Association directly. Buyers must request current dues from the Association or its management company.
- Interior Sqft Range Text — Upper End For Detached Singles — LivingPlaces.com cites ~3,000 sq ft for detached singles; neighborhoods.com cites a range of 2,230–3,936 sq ft across the community broadly. No single authoritative source publishes a complete verified range for detached singles specifically. Buyers should confirm in public records.
- Community Amenities — Playground/tot Lot — Redfin public sales data notes HOA amenities include ‘Common Grounds, Tot Lots/Playground’ but no dedicated community amenity page on northbrookgv.com independently confirms a specific playground structure or trail. A listing narrative references ‘a babbling creek’ and wooded backdrop but no formal trail map is published by the HOA.
School District
Northbrook is served by the Garnet Valley School District. Buyers should verify current school assignments directly with the district.
