FAQs
What is a Lot Development Plan (LDP)/Site Plan?
A lot development plan (LDP) is a sketch depicting the proposed development for a particular lot. It is prepared by a certified engineer for the purposes of building permit application.
I have an easement on my property, what does that mean?
The purpose of the easement is to protect buried infrastructure which has been installed on a portion of your property (i.e. Storm Sewer). This easement gives legal access to Municipal officials to enter onto the land for the purposes of inspection/maintenance. Sheds, pools, decks, fencing or any means of blocking or altering the easement may not be permitted.
What is a Building Lot and Location Survey?
A Building Lot and Location Survey (also known as the Real Property Survey or BLS) shows the as-built location of the structures constructed. It is prepared by a Surveyor following foundation completion. Your BLS should be referenced when determining the location of exterior structure such as fences. Two copies of the real property survey are included in your closing documents.
What are Subdivision Restricted Covenants?
In some instances a Subdivider will register on the title of new Subdivision lands Restricted Covenants dealing with issues relating to parking, fencing, landscaping etc. in the Subdivision. These Restricted Covenants are between the Subdivider and property owners. The Municipality has no involvement. These should be discussed with a Solicitor.
How do I proceed?
You should review your Agreement of Purchase and Sale and Restrictive Covenants. The installation of a pool may result in changes to the grading or drainage; please note: all change to grading or drainage must be approved by Doug Tarry Homes. Authorization from the Municipality is required.
More info can be found on the FAQ page of our website.
