Why deck permits get rejected

Refused, or sent back?

Most deck applications are not refused outright. They come back with correction comments: something is missing, unclear or outside the rules, and the review stops until you answer. A real refusal happens when the deck itself cannot be approved where and how it is drawn, for example because it sits in an easement. Both cost time. The reasons below come from what building departments publish about decks, so you can check your file against them before you submit.

Where the deck sits: setbacks and easements

This is the first thing a reviewer measures. Setbacks are the minimum distances between a structure and the property lines; easements are strips of your lot that a utility or the city can use.

• Setbacks change with height. In Thornton, Colorado, decks between 30 inches and 8 feet high may reach to 10 feet from the rear property line, but decks over 8 feet tall must meet the full required rear setback, which the city says prevents decks from looming over a neighbor's property^[1]. Enclosed decks must meet the full building setbacks^[1].
• Easements are off limits. Thornton allows the setback encroachment only as long as the deck does not encroach into any easement^[1]. Hanover, Minnesota, says decks go outside drainage and utility easements and outside building and septic setbacks^[2].
• Front yards have extra rules. Thornton requires decks in the front yard to be compatible in materials and colors with the home, and decks larger than 480 square feet in the front yard need a separate Minor Development Permit^[1].

A deck that crosses one of these lines is drawn in the wrong place, and no correction letter fixes that. Moving or reshaping it does, or a variance.

What the site plan is missing

The site plan is how the city checks the paragraph above, so a vague one gets sent back. Hastings, Minnesota, asks for a scaled drawing that accurately shows the deck with its distances from property lines, utility easements, power lines and other structures^[4]. Hanover asks for the proposed structure and existing buildings, the distances to property lines, easements and setbacks, and the location of the well, septic system and driveways, on a survey or site plan^[2].

Hanover also lists the cases in which it may not require a certificate of survey, such as when the city already has a foundation as-built survey of the home, or when the deck would be at least 5 feet from any rear setback line, wetland buffer or drainage and utility easement^[2]. Outside its list, plan on a survey.

Structural details that do not match the code

When a city publishes prescriptive deck details, the reviewer compares your drawings to them line by line. The City of Alexandria, Virginia, says construction cannot deviate from its details unless prior approval is obtained^[3]. Common mismatches:

Guards are another frequent comment. Hastings requires a guard at least 36 inches high on every deck 30 inches or more above grade, built so a 4-inch sphere cannot pass through and able to withstand a 200-pound lateral force^[4].

Rules the city does not enforce, but someone else does

A building permit does not settle your homeowners association. Milpitas, California, states that on a property regulated by an association, any exterior work must have the association's approval, and that getting it is the owner's responsibility^[9]. An HOA refusal will not appear in the city's review, but it can still stop the project.

When the answer is a variance

If the deck cannot fit the setback, the alternative to redesigning is a variance: a request for permission to depart from the zoning rule. It is a separate application with its own fee. Canandaigua, New York, lists $100 for an area variance in its 2026 fee schedule^[5]. A variance is decided case by case, so it is not a formality to plan around.

Building it anyway

Some owners decide to build first and ask later. Cities have answers for that:

• Stop-work orders and extra fees. Carmel-by-the-Sea, California, issues a stop-work order for work begun without a required permit, and charges a stop-work investigation fee in addition to double permit fees before it will issue the permit^[6].
• Penalties to legalize, or to remove. In New York City, legalizing work done without a permit on a one- or two-family home carries a $600 penalty, and removing the work instead carries the same penalty^[7].
• It follows the house. Fairfax County, Virginia, applies its rules on unpermitted construction to properties that have been bought and sold, regardless of when the construction was done^[8].

How to avoid the corrections

Build the file the way the reviewer reads it: a site plan with every distance and easement, a framing plan inside the prescriptive tables, the ledger and footing details your city publishes, the guard and stair details, and a note on anything outside them. Then answer every comment in one resubmission. That is the job the All-in offer does: our permit team prepares the file for your city's rules, reviews it before you file, and handles the city's comments until the permit is issued.
