Building in Spring Hill

Spring Hill straddles Maury and Williamson counties about 30 miles south of downtown Nashville, in subdivisions such as Port Royal Estates, Wades Grove, Aston Woods, Wyngate Estates, Grand Reserve and Hampton Springs. Permits come from the city’s Building Codes and Inspection Department on Station Hill Drive, and the Unified Development Code sets the rules below.

Fences

From 5 feet behind the front of the house out to the front lot line, a fence can be 36 inches. Side and rear yards allow 6 feet, with the finished side facing away from your lot. The code requires a permit for any fence over 36 inches, and the city’s fence permit form asks for a survey and a $25 fee. On a corner, nothing between 3½ and 8 feet tall can stand within 30 feet of the intersection along either street.

Decks and hot tubs

A deck needs a building permit with a plot plan. A low deck, 4 feet or under, can’t go in the front yard, and a taller one has to be at least 5 feet from the side and rear lot lines. Setting a hot tub or swim spa on a deck brings an engineer into the permit because of the weight.

Retaining walls, fireplaces and pergolas

A retaining wall over 3 feet needs plans from a licensed engineer with the building permit, and walls can’t go in the front or corner-side setbacks. An outdoor fireplace needs no building permit but belongs in the rear yard, 10 feet from the lot lines. Gazebos and pergolas stay out of the front yard and 5 feet from the side and rear lines, while arbors and trellises need no permit at all.

Driveways

Every residential curb cut needs the City Engineer’s approval. Each lot gets one, and the driveway can be up to 26 feet wide within the front setback.

Spring Hill questions

How tall can a fence be in Spring Hill, TN?

Six feet in side and rear yards. From 5 feet behind the front of the house out to the front lot line, the limit is 36 inches. Spring Hill requires a permit for any fence over 36 inches, and the city’s form asks for a survey and a $25 fee.

Can I put a hot tub on a deck in Spring Hill?

Yes, but the deck needs an engineer. Spring Hill’s deck permit checklist calls for engineering when a hot tub or swim spa sits on the deck, because of the weight of the water. Every deck also needs a building permit with a plot plan, and decks over 4 feet stay 5 feet from side and rear lines.

When does a Spring Hill retaining wall need an engineer?

Over 3 feet. Spring Hill requires plans from a licensed engineer with the building permit for any retaining wall taller than 3 feet, and walls aren’t allowed in front or corner-side setbacks. A slope that needs more height is often split into terraced walls to keep each tier under the limit.

Do I need a permit for an outdoor fireplace in Spring Hill?

No building permit is needed for an outdoor fireplace in Spring Hill, but it has to go in the rear yard and stay 10 feet from every lot line. Gazebos and pergolas also stay out of the front yard, 5 feet from side and rear lines, while arbors and trellises need no permit.
