When, and how much?
For the majority of projects that involve a structural change, whether "up" or "out", a full survey by a licensed surveyor is a "must-have". In Seattle, the fee to have a property surveyed averages between $2,500 and $3,000 for a typical urban residential lot and up to $5,000 for larger or more complex lots, depending on factors such as the distance to nearest recorded monuments, the presence of environmentally critical areas (steep slope, known landslides, etc.), and the quantity and complexity of the existing improvements.

Since subsequent visits to record additional information are not included in the initial price, a list of information required by your local jurisdiction should be provided to your surveyor, to ensure that all it is acquired in a single visit.

Basic requirements
Here are a few of the checklists and standards for the city of Seattle:

SDCI Tip 103 - Site Plan Requirements

SDCI Tip 327A - Environmentally Critical Areas

Be sure to check the City of Seattle Department of Planning and Development for the most current version of these documents prior to use.

Similar information for other jurisdictions can be found by searching for "land use department" or "planning department" and the name of your city and/or county.

Be sure to also ask for...
In addition to this list, I always request the following additional information:

  • elevation of every corner 

  • elevation of finished floor at every door

  • elevation of every ridge

  • top elevation of every overhang

  • horizontal dimension from the outside edge of the overhang (or face of fascia) to the face of the foundation

  • diameter of trunk and species of all trees with trunks greater than 3" in diameter

  • locations of all impervious surfaces with type of material labeled (concrete, asphalt, crushed rock)

  • adjacent right of way (full width) 

  • neighboring structures within 20' of property line (If you are changing the front of your house, you may need to have the entire front of both adjacent houses surveyed in order to determine your setback by way of "front yard averaging.")

  • For properties where we may be building close to underground utilities, recorded locations of all existing underground utilities. The marking of underground utilities is usually done by a separate company, subcontracted by the surveyor prior to their visit to measure your property. This cost is not typically included in the surveyor's estimate, but is sometimes free and usually not more than a few hundred dollars. The underground utility locators can also mark depths of items - sometimes critical for locating new foundation walls and new sewer or stormwater connections, if requested. 

Avoid conflict.
Whether or not you anticipate problems, making changes to your home's appearance is something that the neighbors will be concerned about. For strategies to prevent or resolve conflict, see WHEN NEIGHBORS DISAPPROVE - 6 TIPS FOR SUCCESS.

When Neighbors Disapprove - 6 Tips for Success

1- Know your property.
For the majority of projects that involve a structural change, whether "up" or "out", a full survey by a licensed surveyor is a "must-have". In Seattle, the fee to have a property surveyed averages between $2,500 and $3,000 for a typical urban residential lot and up to $5,000 for larger or more complex lots, depending on factors such as the distance to nearest recorded monuments, the presence of environmentally critical areas (steep slope, known landslides, etc.), and the quantity and complexity of the existing improvements.

2- Be a good neighbor.
The golden rule "Do unto others as you would have them do unto you" holds true. If you have been opinionated and difficult in the past about your neighbor's projects, they are more likely to act the same when it is your turn. If you've had troubles in the past, it is a good idea to try to repair relationships in earnest long before you begin the design process.

3- Communicate.
If you plan to change the appearance of the exterior of your home in any significant way (including paint color), it makes sense to let your neighbors know your plans. You are not (necessarily) asking for permission, rather letting them know what kind of disruption to anticipate and how they should handle any issues that arise, such as blocked access, property damage, etc.

4- Know your rights.
Sometimes, questions arise which are difficult to answer with certainty. If your property has easements, encroachments, or other complexities involving property lines, it would be wise to do some research. This may be in the form of a feasibility study, a binding meeting with the relevant parties at your land use department, and/or legal advice from an attorney who specializes in residential real estate law. As an architect, I advise my clients when such additional measures are appropriate. It is less expensive to secure your footing in the beginning than it is to fight your way through a dispute when you are in construction.

5- Have an alternate plan.
One of my former clients planned to add a porte cochere, a historic type of carport, onto the side of his house. His property was located in a historic preservation overlay district, where many of the neighborhood homes had this feature. There was plenty of room on his property, and the structure was permissible under the current zoning code without requiring a variance. However, due to the overlay district, design approval was required from a separate committee, prior to permit approval. When we presented the design for consideration, the neighbors attended the meeting to lobby against the porte cochere - not because they didn't like the idea or design, but because they didn't like my client!

In the end, we did not get approval for the covered carport, but we did accomplish the goal of providing off-street parking by capitalizing on the fact that the committee did not have purview of driveways, curb cuts, or fences. Our "Plan B" was to install tire strips and a parking pad made of permeable pavers. The homeowner now parks where he had originally hoped, and walks up a set of side stairs directly onto his porch, getting out of the rain quickly. When there is no car parked in the driveway, the permeable pavers look like a grass lawn.


Parking beside the porch steps was a viable alternative to a porte cochere.

6- Offer up something.
When all else fails, offer up something. In the past, I've known clients to share or carry the expenses on things such as tree removal or pruning, new fences, landscaping, privacy screens, sewer repair, and burying overhead cables. All of these things cost money, but they are often items which were desired - or would soon have been required.

My Architecture Education Started Early

Here I am, age 3, helping my Dad build a treehouse. I didn't realize that it was meant for my brother until it was finished and only had a knotted rope for access. He is almost 5 years older than me, so that was just "perfect" for him - a haven away from his little sister! Dad realized that I was not going to give up on the idea of playing up there, so he built a set of steps for me. Years after it was built, when my brother had outgrown the need for the playhouse, it was finally mine. So, I set about remodeling. I painted it with the leftover (pink!) paint from my bedroom, hung curtains, moved in my kitchen wares, and held the cats hostage there as my "babies".
